This study concluded that while home-based intense pulsed light, laser diodes, radiofrequency, and light-emitting diode devices are recommended for certain skin conditions, ultraviolet B phototherapy for psoriasis showed mixed evidence compared to clinic treatments.

This study found that Imaging Mass Cytometry effectively visualizes multiple biomarkers in alopecia areata, enhancing analysis of immune cell and tissue interactions in hair pathology.

This study found that iodine deficiency, iodine excess, or the presence of antithyroid substances affected growth and behavior in Wistar rats, leading to various symptoms such as lethargy and alopecia.

Henna orange powder, especially with alkali, protects and colors hair better than oxidizing colorants.

In this study, the authors found that rabbit hair material ground for 8 hours had better suitability and histocompatibility for injectable soft tissue augmentation compared to other tested formulations.

This chapter reviews the available options for camouflaging hair loss and thinning, discussing their advantages and disadvantages, but reports no new clinical results.

This study found that overexpressing human Bcl-2 in mice protected epidermal keratinocytes from UVB-induced apoptosis but unexpectedly increased apoptosis during hair follicle regression and chemotherapy.

This study found that low-dose UVB radiation enhances the survival, migration, and hair growth-promoting capacity of adipose-derived stem cells in mice through the generation of reactive oxygen species.

In this study, autophagy was commonly observed during keratinization in neonate rat hair follicles, suggesting lysosomal proteases and cytoplasmic enzymes may coordinate in hair follicle cell differentiation.

This study found that purified apple juice containing procyanidin B-2 promoted hair growth in both mouse models and human clinical trials for male pattern baldness.

In this study, UVB exposure was found to alter certain chemical properties of the hair shaft, such as keratin components and water content, without significantly affecting its physical morphology.

This review of Leon Sperling's Atlas of Hair Pathology discusses the visual and diagnostic value of its comprehensive coverage on hair and scalp diseases but reports no new clinical findings.

This study found that Gynostemma pentaphyllum leaf hydrodistillate (GPHD) promoted hair growth in mice similarly to minoxidil and upregulated growth factor expression via the AKT/β-catenin signaling pathway, with damulin B identified as an active component contributing to these effects.

This study found that a supplement containing cystine, B vitamins, and minerals improved hair condition in 34 women with diffuse hair loss over six months, as evidenced by an increased anagen/telogen hair ratio, positive participant feedback, and no serious side effects.

This study found that quercetin-loaded solid lipid nanoparticles demonstrated positive protective effects on human hair against UV-B light, as they controlled microscopic surface roughness, reduced chemical changes, and minimized protein loss in vitro compared to other treatments.

This study found that Silibinin-loaded polymeric micelles significantly protected human hair from UV-B induced structural and chemical damage by preventing increases in roughness and reducing protein loss.

In this study, the researchers reported that activin B combined with bone marrow-derived mesenchymal stem cells enhanced wound healing and hair follicle regeneration in rats by promoting cell migration through the ERK and JNK pathways.

This study found that cutaneous pyridoxal 5'-phosphate hydrolase activity may be carried out by an enzyme different from the classical tissue-nonspecific alkaline phosphatase in human and mouse skin.

This study found that domestic temporary hair dyes may pose a health risk due to their cytotoxic effects on human red blood cells and NIH/3T3 cell lines.

In this pilot study, both microneedling and CO2 laser combined with hair transplantation and nbUVB demonstrated potential for inducing repigmentation in refractory palmar-plantar vitiligo, though further research is needed to ascertain their relative efficacy.

This review discusses potential cosmeceutical treatments for hair loss, including ingredients like procyanidins and isoflavones, but does not present new clinical outcomes; the authors highlight the promise of further research.

This study found that keratin 17 and TNFα play interdependent roles in regulating hair follicle cycling, with TNFα required for the anagen–catagen transition and its ablation partially rescuing hair cycling defects in K17-null mice.

Certain micronutrients may improve hair and nail health, but more research is needed to confirm their benefits.

This study identified that in mice, sweat gland development is directed by mesenchymal signals that suppress SHH-production, while in humans, this occurs through a BMP spike in embryonic development.

This study found that blocking corticotropin-releasing factor receptors with astressin-B promoted hair regrowth and prevented alopecia in a mouse model of stress-induced hair loss.

This article discusses the need for rational strategies in developing hair loss drugs targeting specific events in hair follicle cycling, reporting no clinical findings but emphasizing the importance of understanding molecular controls.

This study found that activin B promotes epithelial wound healing in mice through the RhoA-Rock-JNK-cJun signaling pathway, suggesting a potential therapeutic role for activin B in wound repair.

This study found that a polyherbal gel made from guava leaves, amla, and aloe is effective against candidiasis on the skin, with additional benefits of nourishing hair and preventing premature graying.

This study found that gels containing glycyrrhizic acid and aqueous Glycyrrhiza glabra extract significantly reduced underarm hair growth in terms of area, thickness, length, and number compared to their gel bases.

North American ginseng extract helped regrow hair in balding mice.
