Special Issue Information

Dear Colleagues,

Healthy hair is one of the most prominent and best visible signs of health, youth and attractiveness in human beings. Weathered hair, hair loss and hair greying are hallmarks of aging. Therefore, people go to great lengths to beautify their hair and delay the effects of time.

Hair problems can lead to psychological distress and low self-esteem. A healthy scalp accompanies healthy hair. Scalp issues range from an oily and itchy scalp to seborrheic conditions such as dandruff. Hair and scalp conditions may arise from various stimuli causing any kind of stress. Examples are environmental impacts such as solar irradiation, air pollution and nutrition, and changes in neuroendocrine status, but also from mechanical impacts such as blow drying, iron flattening or coloring and bleaching hair. On the molecular level, these stimuli may lead to oxidative stress or inflammation, compromised scalp-barrier strength and damaged hair fibers.

The science on hair follicles and scalp skin has focused on deciphering the complex and tightly orchestrated molecular pathways regulating hair and scalp health. Further research could help us to better understand the mechanisms behind a healthy scalp and healthy hair, and pave the way for the better treatment of unwanted scalp and hair conditions.

Therefore, I, together with my co-editors, invite you to submit a manuscript on your recent research in the field or a review article for this Special Issue “Scalp and Hair Health” in the journal Cosmetics (MDPI publisher). Based on your previous published work and your expertise in the field, we are sure you will make an excellent contribution to this Special Issue.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cosmetics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

(1) Background: Environmental factors, such as airborne pollutants and solar UV, induce oxidative damage to proteins and lipids on hair fibers, leading to decreased hair strength and shine, increased fiber porosity, brittleness, dryness, and stiffness. Traditional methods used for hair damage/protection/reparation assessment show limitations in sensitivity or specificity for evidencing the benefits to be gained from the protection/reparation of hair fibers against environmental stressors. (2) Methods: Ex vivo experimental models of hair fibers exposed to urban pollutants and UV irradiation were developed. Targeted proteomics approaches for the quantification of oxidatively damaged (carbonylated) proteins on hair fibers were optimized. (3) Results: A significant dose-dependent increase in carbonylation both in the cuticle and cortex proteins was observed upon exposure of hair fibers to particulate matter and UV-A radiation, at daily stress equivalent doses. Increased protein carbonylation on keratins and keratin-associated proteins led to loss of hair fiber structural integrity. The oxidative modification of proteins induced by urban pollution exposure led to hair cuticle structural damage revealed by an increased permeability. However, protein carbonylation was prevented in the presence of antioxidant compounds. (4) Conclusions: Protein carbonylation is an early event in hair fiber damage which can be used as a reliable biomarker for the efficacy of hair care interventions against environmental stressors.

Solar radiation is a significant source of damage to hair fibers. However, the instrumental measurement of the consequences of its interaction with hair fibers’ constituents remains a challenge. In this work, the flexabrasion methodology was investigated as a potential tool to quantify the damage to mechanical hair properties caused by solar rays. The in vitro experiment developed for this study simulated four initial conditions of human hair samples, which subsequently underwent different periods of exposure to the radiation emitted by a Xenon arc lamp source. The statistical analysis of the results characterized the methodology’s ability to evaluate the impact of solar radiation on the hair’s mechanical resistance. More evident effects were observed on natural fibers subjected to exposures of up to 60 h and over, corresponding to about 1.5 h per day of sun exposure in Rio de Janeiro over five months. The results point to flexabrasion as an option to evaluate the photoprotection efficacy offered by hair-care products. Full article
