Special Issue Information

Dear Colleagues,

This Special Issue will be focused on all aspects of hair research for science and technology; for example, hair appearance, the measurement of physical properties, microstructure analysis, hair curvature, coloring, pigmentation, decoloration, hair damage and repair, and so on. We have noticed that there have been many advances in recent research on hair science and hair care technologies. Based on your reputation and excellent contributions to these fields, I would like to invite you to contribute either an original piece of research or a review article within the focused area of this issue.

Thank you in advance for your kind consideration. Please let us know if you have any questions.

Dr. Kenzo Koike
Guest Editor

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.

Dermal papilla cells (DPCs) regulate the hair cycle and play important roles in hair growth and regeneration. Alopecia is a pathology caused by a deregulation in the hair cycle phases. Currently, the use of physical therapies such as radiofrequency (RF) as an alternative to pharmacological treatment is increasing. Electrical stimulation by capacitive resistive electrical transfer (CRET) is one of these therapies. The objective of the present study was to analyze the effect of RF-CRET currents on DPCs. Cells were treated with subthermal 448 kHz CRET currents with two different types of signals: standard (CRET-STD) or modulated (CRET-MOD). Viability (XTT Assay), proliferation (Ki67 and ERK1/2), apoptosis (p53 and caspase 3), differentiation (β-catenin and α-SMA), and anagen markers (versican and PPARγ) were analyzed by immunofluorescence and immunoblot. CRET caused effects on the proliferation and survival of DPCs associated with increases in the expression of p-MAPK-ERK1/2, cyclin D1, and decreases in the expression of p53 and caspase 3. Also, CRET caused significant transient increases in the expression of β-catenin, involved in hair growth, and in the expression of anagen phase markers such as versican and PPARγ related to hair follicle maintenance. The present study highlights the ability of treatment with CRET therapy to cause molecular alterations in DPC involved in hair regeneration. Full article

The mitigation of damaged hair conditions involves the application and penetration of substances to stabilize broken bond sites, restore lipids and proteins, reinstate hydrophobicity, and recover hair mechanical properties. Vegetable oils, in general, exhibit a list of advantageous characteristics much desired by consumers, given the associated benefits for hair fibers. While coconut oil is highly popular in the hair care market and extensively studied for its ability to diffuse through the hair cortex, the effects of avocado and argan oil on the internal structure of hair and their potential benefits remain underexplored. Tensile and fatigue tests, as well as Raman spectroscopy, were carried out to investigate the interaction of these three oils with virgin and bleached Caucasian hair. The oils were applied in sufficient amounts directly to hair tresses and maintained for 24 h at 25 °C. Our results show that the three oils successfully diffused and interacted with the cortical region of the hairs. Their impact on hair mechanical properties depends on the level of damage and humidity conditions. In virgin hair, coconut and avocado oil reinforce the hydrophobic barrier of the cellular membrane complex, preventing water from causing intense perturbation of the mechanical properties, leading to increased stiffness and break stress. Meanwhile, due to the high degree of unsaturation of its fatty acid chains, argan oil increases water absorption, resulting in losses in hair resistance. When bleached, the hydrophilicity of the hair fiber increases, determining more affinity for argan oil. Consequently, the affinity with water is also elevated, causing increased fragility to mechanical stress. The analyzed vegetable oils are not always beneficial for hair care. Their specific chemical characteristics and hair conditions will influence the final results and should be taken into consideration in hair care product development. Full article

Hair cosmetics are in fashion. Numerous products are commonly used in combination. Frequent allergens are present in hair cosmetics, which, with almost daily use, increase the risk of sensitization. Familiarity with the clinical distribution of the eczematous rash is necessary to seriously consider patch testing. Not all the products on the market are haptens. It is necessary to know how to patch your own products. When avoidance of the allergen is not possible, new treatments are evaluated to combat allergic contact dermatitis, mainly of the occupational type. In this manuscript, a complete and practical review of the main allergens and contact sources of hair cosmetic origin has been carried out. Full article
