Special Issue Information

Dear Colleagues,

Hair is an important component of body image with unquestionable relevance in society that we can easily change according to culture, fashion, and personal taste. Hair undergoes irreversible changes as a result of cosmetic operations and products as well as environmental assaults and daily routines. This causes the hair to lose some of its properties, such as strength, elasticity, shine, and smoothness. Recent research has proven the beneficial effects of natural-based cosmetic formulations on hair, as they can protect the hair fiber or modulate some of its properties. Furthermore, these cosmetics can be applied over the hair fiber or target the hair follicle, delivering bioactive agents.  

This Special Issues welcomes original works and reviews focused on the development of new classes of natural-based cosmetic formulations and how they affect hair attributes such as color, fragrance, strength, elasticity, shape, shine, and volume. We also welcome submissions on hair biology and on the modulation of the hair cycle.

 The incorporation of new formulations in the creation of alternative hair products in the future will result in innovative, sustainable, and environmentally friendly cosmetic goods that have a significant impact on the cosmetic sector.

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. Applied Sciences 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 2400 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.

Hair Growth Booster Effects of Micro-Needling with Low-Level Led Therapy and Growth Factors on Subjects Treated with Finasteride®

A procedure based on Microneedling (MND) with Low-Level Led Therapy (LLLT) and Growth Factors (GFs) could be a booster for hair re-growth (HRG) in patients assuming Finasteride®. The study examined the clinical outcomes of a multicentric, observational, retrospective, case-series investigation in which MND with LLLT and GFs was applied to patients suffering from androgenic alopecia (AGA) who were prescribed Finasteride®. Twenty-one patients were initially enrolled, of which seventeen males were classified in stage II–VI by the Norwood–Hamilton scale, and four females were classified in stage II–III by the Ludwig scale. One male patient was excluded after screening (exclusion and inclusion criteria evaluation). Twenty patients were analyzed, of which ten patients’ hair growth has stalled after taking Finasteride®, and ten patients did not achieve good results from Finasteride®. HRG assessment was evaluated with photography, physician’s, and patient’s global assessment scale, in addition to standardized phototrichograms during a short follow-up: T0—baseline, T1—20 weeks (wks). A statistically significant improvement in HRG (p = 0.0822) and an increase in hair density of 19 ± 2 hairs/cm2 at T1 after 20 wks (20 wks vs. 0 wks) in the targeted area over baseline (74 ± 2 hairs/cm2 at T1 versus 55 ± 2 hairs/cm2 at baseline) were reported and described as encouraging results. The effectiveness of MND with LLLT and GFs use was demonstrated in patients whose hair growth stalled after taking Finasteride® and in patients who did not achieve good results from Finasteride®.

The permeation and absorption of solutes into human hair are highly relevant to various applications, including the formulation of hair-care products, the development of water pollution control and remediation, and the risk assessment of environmental exposure. Based on a detailed introduction of the structure and composition of hair, the effects of the properties of hair (structure, composition, and charge properties), the physicochemical properties of solutes (molecular size, shape, and hydrophobicity), and the conditions of the surrounding medium (solvent composition, temperature, and pH) on the permeation and absorption were comprehensively analyzed. Several theoretical models were reviewed, including two-part/two-state, porous media diffusion, homogeneous medium diffusion, heterogeneous medium partition, and diffusion models. Finally, future research directions for the permeation and absorption of solutes in hair were proposed to provide a foundation for the further optimization and application of permeation models.
