Scalp diseases are a common issue affecting patients’ self-esteem and quality of life. Currently, trichoscopy is the foundation of diagnostics; however, it does not always provide sufficient sensitivity and specificity. In uncertain cases, scalp biopsy remains the gold standard, though it is an invasive method and not well accepted by patients. In recent years, new non-invasive diagnostic methods have been developed and modernized. This article discusses imaging techniques, emphasizing their development over time as well as their advantages and limitations in the diagnosis of scalp dermatoses. Full article

Tinea incognito is an incorrectly diagnosed form of fungal infection due to a changed clinical picture as a result of systemic or topical corticosteroids or even local immunomodulators. This type of skin lesion is most often located on the trunk but can affect any part of the body. We present a case report of 76-year-old woman with a history of systemic lupus erythematosus who was admitted to hospital because of extensive, painful, and burning erythematous and papular lesions in an annular pattern, covered with a thick, yellow crust, located on the scalp and neck. The skin lesions were accompanied by extensive hair loss. The patient had previously undergone intensified treatment of the underlying disease due to the exacerbation of skin lesions of a subacute cutaneous lupus erythematosus type. A suspicion of tinea incognito was raised, and direct mycological examination and culture confirmed the presence of dermatophytes (Microsporum spp.). Tinea incognito can be difficult to diagnose because the clinical picture is relatively nonspecific and can mimic other dermatoses, such as subacute lupus erythematosus. Therefore, in doubtful cases it is necessary to perform a direct test and culture for fungal infection, especially before initiating treatment with glucocorticosteroids and other immunosuppressive agents.

Background: Androgenetic alopecia (AGA) is a prevalent condition characterized by progressive follicular miniaturization. Minoxidil topical treatment and finasteride oral treatment are the golden standard, but they are limited by local and systemic adverse effects. Combination therapies targeting both follicular stimulation and nutritional support may enhance clinical outcomes. Objective: To evaluate the efficacy of a combined topical and oral therapy compared to topical monotherapy in patients with AGA using trichoscopic and clinical parameters. Methods: In this open-label, prospective trial, 48 patients were assigned to receive either a topical spray alone (Group A) or in combination with oral capsules (Group B) for 3 months. Trichoscopic parameters were assessed at baseline and post-treatment. Paired and independent t-tests, along with Cohen’s d effect sizes, were used to evaluate intra- and inter-group changes. Results: Both groups demonstrated improvements in hair density, thickness, and anagen/telogen ratio. Group B exhibited significantly greater increases in total hair count and anagen conversion (p < 0.05). The effect sizes ranged from small to large, with the most pronounced changes observed in anagen/telogen ratio (Cohen’s d = 0.841) in males. Conclusions: The combination of topical and oral treatment led to greater trichologic improvements than topical therapy alone. While extrapolated projections at 6 and 12 months suggest continued benefit, future studies with longer duration and placebo controls are required to validate these findings. Full article

Primary cutaneous lymphomas (PCLs) constitute a heterogeneous group of rare diseases. Previously, few studies have focused on the aspect of scalp involvement by PCLs. The objective of this study was to analyze the clinical presentation, diagnostic pathways, and treatment methods in patients diagnosed with scalp PCLs. A comprehensive literature review was conducted using the PubMed database, with the search terms “scalp” AND “cutaneous lymphoma”, “folliculotropic mycosis fungoides” AND “scalp”, “trichoscopy” AND “lymphoma”, and “dermoscopy” AND “scalp” AND “lymphoma.” The search was limited to articles published from database inception to May 2, 2024. Based on the title and abstract analysis, we included articles on PCLs involving the scalp. After a thorough review of the full manuscripts, several were excluded due to irrelevance, the absence of essential clinical data, discrepancies in patient age, gender, and diagnosis, and a lack of information pertinent to scalp PCLs. The literature search identified 1482 patients with scalp involvement in PCLs. Of the total number of cases, 1096 were diagnosed with B-cell PCLs, 384 with T-cell PCLs, and two cases lacked a precise PCL diagnosis. Primary cutaneous follicle center lymphoma was the most frequently reported B-cell PCL of the scalp, while mycosis fungoides was the most common T-cell PCL. Alopecia was observed in 69.0% of the patients analyzed, with the most prevalent form being non-scarring focal alopecia. It is imperative to consider the scalp in patients with PCLs, particularly in light of the knowledge that some lymphomas affecting the scalp exhibit a higher degree of aggressiveness. Full article

Alopecia areata (AA) is an autoimmune disorder causing non-scarring hair loss, which is often triggered by psychological stress. Conventional treatments, such as corticosteroids and immunotherapy, show variable efficacy and can cause side effects like hair discoloration. Exosome therapy, utilizing extracellular vesicles, presents a promising alternative, though its use in stress-related AA remains underexplored. A 39-year-old male with unifocal AA on the right parietal scalp developed hair loss following emotional distress after his fiancée’s death. Methotrexate and prednisolone were ineffective, prompting a bioregenerative approach using rose stem cell-derived exosomes (RSCEs) combined with thulium laser therapy. Six monthly sessions of RSCEs (20 mg/vial, 10 billion exosomes) were administered, with laser pre-treatment enhancing absorption. Within one month, vellus hair regrowth appeared, progressing to an increased density and pigmentation at three months. By six months, complete regrowth and natural pigmentation were achieved, with reduced inflammation confirmed by trichoscopy. The therapy was well-tolerated, with no adverse effects. This case highlights RSCE therapy as a promising treatment for stress-induced AA, achieving significant regrowth without corticosteroid-related side effects. Further studies are needed to validate its efficacy and refine protocols for broader clinical applications. Full article

Context: Hair loss (alopecia) presents both aesthetic and psychological challenges, significantly impacting quality of life. Platelet-rich plasma (PRP) therapy has gained prominence due to its ability to deliver growth factors and modulate local inflammation. However, uncertainties remain regarding the mechanisms through which systemic inflammation, oxidative stress, and coagulation factors influence PRP’s efficacy. Objectives: This narrative review explores the impact of inflammatory biomarkers (e.g., NLR, PLR, IL-6, TNF-α) and growth factors (VEGF, TGF-β, FGF) on hair regeneration in PRP therapy. It discusses how oxidative stress and vitamin status (B12, D, folate) correlate with therapeutic success. Additionally, it examines the PRP preparation protocols and combined approaches (microneedling, minoxidil, LLLT) that may amplify clinical responses. Results: The synthesized data highlight that elevated systemic inflammation (increased NLR/PLR values) can limit PRP’s effectiveness, while the regulation of inflammation and optimization of antioxidant status can enhance hair density and thickness. Integrating vitamins and an anti-inflammatory diet into the therapeutic protocol is associated with more stable hair growth and reduced adverse reactions. The variability in PRP’s preparation and activation methods remains a major obstacle, underscoring the need for standardization. Conclusions: Integrating inflammatory biomarkers with oxidative stress indicators provides fresh insights for tailoring PRP therapies in alopecia. Multimodal treatment strategies combined with collaborative multicenter studies—in which biological markers are embedded within rigorous protocols—could establish standardized methodologies and significantly enhance the treatment success.

Background: Frontal fibrosing alopecia (FFA) is a primary cicatricial alopecia, initially described in postmenopausal women but increasingly reported in men. The male form remains under-recognized, often misdiagnosed as androgenetic alopecia (AGA) or alopecia areata (AA), particularly in the beard. Objective: This review aims to summarize the current literature on the epidemiology, clinical presentation, etiopathogenesis, diagnosis, and treatment of FFA in men. Epidemiology and Clinical Features: FFA in men typically presents at a younger age compared to women. Key features include frontal and temporal hairline recession, early involvement of the beard and sideburns, and a high prevalence of eyebrow alopecia (43–94.9%). Facial papules and body hair loss are more common in men than women. Occipital involvement varies widely across studies (8–45%). Clinical features like beard alopecia, often presenting as plaque or diffuse patterns, are highly suggestive of FFA in men but are not part of current diagnostic criteria. Etiopathogenesis: FFA is postulated to have an autoimmune basis influenced by genetic, hormonal, and environmental factors. Genetic studies have identified associations with HLA-B*07:02 and CYP1B1 loci. Environmental triggers include prolonged use of facial sunscreens and moisturizers, as demonstrated in case-control studies and meta-analyses. Diagnosis: Diagnosis is predominantly clinical, supported by trichoscopy and biopsy when needed, particularly in cases overlapping with AGA or AA. Unique presentations, such as beard alopecia and the “watch sign”, highlight the importance of considering FFA in atypical male cases. Treatment: Current treatment protocols in men mirror those for women and focus on disease stabilization. Oral 5-ARi (dutasteride) combined with topical corticosteroids and calcineurin inhibitors form the first line. Additional treatments include intralesional corticosteroids, oral isotretinoin for facial papules, and minoxidil for associated AGA. Surgical hair transplantation remains controversial, requiring disease control and careful patient counselling. Conclusions: FFA in men presents with distinct clinical features and challenges in diagnosis, often overlapping with other alopecia. Further studies are needed to validate diagnostic criteria and evaluate treatment efficacy in this underrepresented population. Full article

Background/Objectives: Alopecia is a common and distressing hair loss condition that poses a major diagnostic challenge. While histopathology is the gold standard, its invasive nature limits its routine use. Trichoscopy, a non-invasive imaging technique, has shown promises in diagnosing and differentiating the various alopecia subtypes. However, existing diagnostic algorithms primarily rely on dermoscopic findings. To address this, we developed a novel, three-step algorithm that integrates clinical and trichoscopic features and employs pattern analysis as a diagnostic tool. Methods: A comprehensive literature review was conducted to identify key trichoscopic features associated with different alopecia types. The gathered data were used as a base for the description of trichoscopic features and patterns for each subtype of alopecia, either scarring or non-scarring. Results: The proposed algorithm is analyzed into three steps. In the first step, alopecia is categorized by distribution into: patchy, patterned, or diffuse. In the second step, it distinguishes between scarring and non-scarring alopecia based on the absence or presence of follicular ostia, respectively. Lastly, in the third step, alopecias are distinguished based on specific trichoscopic clues, allowing for the identification of distinct trichoscopic patterns. Conclusions: The three-step diagnostic algorithm for alopecia, utilizing clinical and dermoscopic findings, performs a pattern analysis in trichoscopy, leading to a dermoscopic diagnosis with great confidence, and minimizing the need for invasive diagnostic procedures.

Background/Objectives: High-frequency ultrasound (HFUS) has been reported to be useful for the diagnosis of cutaneous diseases; however, its two-dimensional nature limits the value both in quantitative and qualitative evaluation. Three-dimensional (3D) visualization might help overcome the weakness of the currently existing HFUS. Methods: 3D-HFUS was newly developed and applied to various skin tumors and inflammatory hair diseases to assess its validity and advantages for dermatological use. Results: Three-dimensional images were successfully obtained from skin tumors, including basal cell carcinoma, subungual squamous cell carcinoma, Bowen’s disease, and malignant melanoma, as well as inflammatory hair loss diseases including alopecia areata in different disease phases and lichen planopilaris. Vertical and horizontal images were generated from the original 3D image data and assessed in comparison with histopathological and/or dermoscopic images. By additionally obtaining horizontal data, lateral tumor margins at any depth were visualized in tumors. In inflammatory hair loss diseases, signs potentially associated with disease activity and pathology were detected. In addition, horizontal evaluation helped grasp hair cycle status and hair follicle densities. Conclusions: These findings suggested that this novel technology holds promise as a robust noninvasive tool to diagnose and evaluate various cutaneous diseases. Full article

Pityriasis rubra pilaris (PRP) presents a diagnostic challenge due to its varied clinical manifestations and the scarce literature on scalp involvement. This article presents a case report of a 59-year-old female with PRP solely affecting the scalp, detailing its clinical, trichoscopic, and histopathological features. Trichoscopy revealed a novel finding of white-silvery scales forming hair casts with a triangular shape, distinct from the existing literature. A literature review comparing our findings with pertinent articles underscored the uniqueness of our case. We discuss differential diagnoses and treatment options, based on available evidence. Our case highlights the importance of understanding scalp manifestations in PRP, enhancing diagnostic accuracy, and improving treatment strategies for this rare condition. Furthermore, the review of the literature compares our observations with available case reports and case series, outlining differential diagnoses and trichoscopic and histopathological diagnostic approaches to PRP, enriching overall clinical knowledge of PRP.

This study aimed to assess the impact of a combination of probiotic strains of Lactiplantibacillus on the treatment of androgenic alopecia (AGA). To this end, 136 individuals with AGA (62 men and 74 women) aged 18–65 years were enrolled in a double-blind, parallel-group clinical trial. A total of 115 individuals (57 in the probiotic group and 58 in the placebo group) completed this study within a 16-week intervention period. Capillary density, thickness, and length of hair were analyzed before and after the intervention using FotoFinder Trichoscale Pro. In addition, the gut microbiota was assessed by paired-end sequencing on the Illumina MiSeq platform (2 × 300 bp). At the conclusion of the treatment period, a notable decline (p < 0.05) in the number of telogen hairs was evident in the probiotic group while hair thickness decreased in the placebo group (p < 0.05). However, the remaining variables did not exhibit any statistically significant changes. In the probiotic-treated group, individuals aged less than 37.5 years exhibited a reduction in the number and density of telogen hair (p = 0.0693 and p = 0.0669, respectively) and an increase in hair length (p = 0.0871). Furthermore, a notable decline in the number and density of vellus hair (p < 0.05) was observed, and this was accompanied by no change in the hair thickness. The probiotic-treated group exhibited a significantly higher abundance of Lactobacillus (p-adjusted < 0.05, DEseq2 test) and demonstrated a notable reduction in the number and density of telogen hair, and this was accompanied by an increase in the percentage of anagen hair. The probiotic mixture was well tolerated by the participants, with a treatment adherence rate of 90%. In light of this study’s limitations, it can be concluded that a mixture of three strains of Lactiplantibacillus promotes the presence of terminal follicles, preventing their gradual miniaturization, which is a characteristic of AGA.

Scalp metastases (SMs) are particularly noteworthy, representing around 4–7% of cutaneous neoplasms in this region of the body, possibly due to its rich blood supply. Diagnosis of SMs involves a systematic approach encompassing oncologic history, clinical examination, dermoscopy, imaging, and histopathological assessment. Clinical presentations of SM can vary, but dermoscopy reveals unique vascular patterns aiding in diagnosis. Imaging, particularly MRI and CT, and histopathological evaluation are mandatory for definitive diagnosis. Treatment strategies vary depending on tumor characteristics and staging, ranging from surgical excision to systemic therapies like chemotherapy or radiotherapy. Multimodal approaches tailored to individual cases yield optimal outcomes. The diagnostic tools available do not always allow SMs to be diagnosed, and often the lack of knowledge on the part of oncologists in suspecting SMs can delay an early diagnosis. This review provides clinicians with a practical guide for the timely diagnosis and management of SM, emphasizing the importance of a multidisciplinary approach and personalized treatment strategies for improved patient outcomes.

Background: Teledermatology is the application of information and telecommunication technologies in the field of dermatology to provide remote care services based on the exchange of clinical information within a network of professionals or between professionals and patients. Tele-trichoscopy is a non-invasive, inexpensive, and easy-to-use method that applies the principle of surface microscopy at different magnifications. Alopecia areata is a non-scarring alopecia with a chronic evolution, which often needs a close follow-up. Objectives: The aim of our work was to analyze the possible benefits of telemedicine for the follow-up of patients with alopecia areata. Materials and Methods: We enrolled patients with alopecia areata, identified during the first trichological evaluation, and we divided the patients into two groups. One group was provided with the devices necessary for a telemedicine follow-up. The other group had a conventional follow-up. The total follow-up time was one year. All of the patients’ photos were blindly evaluated by a team of expert dermatologists who were asked to indicate the quality of the images. The photos were also evaluated to identify disease markers. During the follow-up period, questionnaires were administered to both groups of patients to assess the quality of the visit, the level of patient satisfaction, and to identify any issues encountered by the patients. Results: There was a high degree of concordance between the images obtained by outpatient trichoscopy and those obtained by telemedicine. The satisfaction levels were the same between the patients followed via telemedicine and those seen in the outpatient clinic. Conclusions: Telemedicine applied to trichology using trichoscopy was proven to be a valid system for managing the follow-up of patients suffering from chronic recurrent scalp diseases and, above all, for maintaining continuity of care.

Tinea capitis is a fungal infection of the scalp and hair caused by dermatophyte molds, that most often affects children and may also affect adults. Previous estimates suggest that between 3% and 11% of all tinea capitis cases worldwide occur in adults, although updated epidemiological studies are needed to reassess the prevalence of tinea capitis in adult populations specifically. Postmenopausal adult women are most often affected by tinea capitis, with African American or Black women particularly at risk. Adults who experience crowded living conditions, who live in close proximity to animals, who are immunosuppressed, and/or who live in households with affected children are at greatest risk of infection. Tinea capitis can be non-inflammatory or inflammatory in nature, and the subtype affects the extent and severity of clinical symptoms. Fungal culture and potassium hydroxide preparations are the most commonly used diagnostic tools. Trichoscopy, defined as dermoscopic imaging of the scalp and hair, is a useful adjunct to the physical examination. The mainstay of therapy is oral antifungal therapy, and topical therapy alone is not recommended. Since tinea capitis infection is uncommon in adults, there are no widely accepted treatment guidelines. Rather, the same medications used for tinea capitis infection among children are recommended for adults at varying doses, including griseofulvin, and terbinafine, and, less commonly, itraconazole and fluconazole. The prognosis for tinea capitis in adults is typically excellent when prompt and adequate treatment is administered; however, delayed diagnosis or inadequate treatment can result in scarring alopecia. Over the past decade, dermatophyte infections resistant to treatment with topical and oral antifungal agents have emerged. While tinea capitis infections resistant to antifungal therapy have been rarely reported to date, antifungal resistance is rising among superficial fungal infections in general, and antifungal stewardship is necessary to ensure that resistance to treatment does not develop among dermatophytes that cause tinea capitis.

Alopecia constitutes one of the most common dermatological disorders, and its steadily increasing prevalence is a cause for concern. Alopecia can be divided into two main categories, cicatricial/scarring and non-cicatricial/non-scarring, depending on the causes of hair loss and its patterns. The aim of this study was to investigate the relationship between anthropometric and nutritional laboratory parameters in Caucasian adult women and men with non-cicatricial alopecia. A total of 50 patients (37 with non-cicatricial alopecia and 13 healthy controls) were included in the study. Clinical examination and scalp trichoscopy were performed. The anthropometric and nutritional laboratory parameters were collected and analyzed. No statistically significant differences in the laboratory findings were found. The patients with non-cicatricial alopecia were statistically significantly younger as compared to the controls. An elevated risk of hair loss, which was detected among the younger participants, might be associated with a modern lifestyle and the so-called ‘Western diet’. It seems safe to assume that suboptimal nutrition and poor eating habits during childhood might constitute risk factors for early hair loss. Full article
