This study found that oregonin, isolated from Alnus japonica, demonstrated strong antioxidant activity and apoptosis modulation in hair follicle cells, suggesting its potential as a natural ingredient for preventing hair loss in cosmetic products.

In this study, researchers explained that healing of extensive skin defects involves granulation filling the wound cavity, followed by epithelialization from skin edges and hair follicles, which are crucial steps in wound healing.

This study found that Sida cordifolia collected in Colombia is a good source of steroidal saponins, which may contribute to its antioxidant and antifungal properties.

This study found that rabbits fed a diet deficient in Vitamin E developed severe muscular dystrophy that was not fully prevented by adding selenium, Vitamin E supplements, or natural feedstuffs, indicating other nutritional deficiencies.

This research outlines how retinoids, compounds based on vitamin A, activate nuclear receptors to influence cellular processes such as differentiation and carcinogenesis, with benefits like anti-inflammatory properties but requiring careful management of dose-dependent side effects.

This case report describes a 33-year-old woman whose symptoms improved significantly after vitamin D and zinc supplementation, highlighting the importance of diagnosing and managing deficiencies to enhance quality of life in young women.

This study found that 66% of patients with hair loss also have vitamin D deficiency, with a significantly higher prevalence among women than men.

This study investigates the relationship between vitamin B12 levels and chronic telogen effluvium, reporting that the role of vitamin B12 in its pathogenesis remains unclear.

In this study, two patients with long-term total parenteral nutrition and no biotin intake experienced hair regrowth after biotin supplementation, suggesting biotin deficiency can lead to alopecia.

This study found that in young male rats, cortisone acetate inhibited body growth and caused alopecia, which vitamin B12 and aureomycin largely counteracted, especially when combined.

This randomized control trial reported that patients with alopecia areata typically have lower serum Vitamin D levels, and treatment with topical vitamin D3 analogue calcipotriol led to significant hair regrowth in 71% of participants over six months.

This chapter provides an overview of phytochemicals with properties to combat alopecia and discusses the potential of flavonoids, found in several herbs, as a safer alternative to synthetic hair loss treatments due to their long-term skin compatibility.

This study found that vitamin C deficiency in neonatal dairy calves is closely associated with skin problems like dermatosis, but treatment with vitamin C led to improvements.

This study found that methyl nonanoate and methyl caprate significantly enhanced the skin penetration of minoxidil compared to solutions with other common enhancers like Azone, DMSO, or DEET.

This study found that individuals with androgenic alopecia had higher levels of vitamin D compared to those with telogen effluvium and healthy controls.

In this study, researchers found that female COVID-19 patients experiencing hair loss had higher testosterone levels and lower Vitamin D levels than healthy controls, suggesting these hormonal factors may play a role in post-COVID-19 hair loss.

This study observed that women with hair loss had significantly higher serum prolactin levels compared to healthy controls. Additionally, a positive correlation between prolactin and vitamin D levels was reported, indicating potential roles for these factors in women's hair loss.

This double-blinded randomized clinical trial found that combining topical vitamin D analog (calcipotriol) and intra-lesion PRP led to a greater reduction in hair loss severity in alopecia areata patients compared to either treatment alone, with significant improvements observed across all groups.

This case report details a patient with autoimmune hypothyroidism who experienced multiple health issues that improved with comprehensive treatment including Thyroxin replacement and other supportive measures.

This research observed that some hypothyroid patients on adequate levothyroxine therapy continue to experience symptoms like poor concentration and hair loss, with findings suggesting an elevated anti-TPO level increases the likelihood of such symptoms, despite normal TSH levels.

This case report describes a 3-year-old boy with atrichia with papular lesions, emphasizing that dermoscopy, showing the 'cluster of stars' appearance, facilitated diagnosis without needing a skin biopsy.

This review describes the molecular interactions between androgens and Wnt/ß-catenin signaling in androgenetic alopecia but reports no new experimental or clinical findings; the authors discuss potential Wnt/ß-catenin-targeted treatments for hair growth.

People with vitiligo may have a lower risk of heart disease.

This study observed that women with telogen effluvium had significantly lower vitamin D levels compared to control subjects, suggesting a possible link between vitamin D deficiency and this type of hair loss.

This case report describes a 56-year-old male with chronic watery diarrhea, hyperpigmentation, and alopecia, in whom colonoscopy revealed multiple polypoidal lesions from the distal transverse colon to the rectum.

UV radiation may cause DNA changes in skin, certain UVB therapy helps psoriasis, a new gene mutation is linked to mild piebaldism, different immune cells affect psoriasis, a drug promotes hair growth, and some cancer drugs could treat skin barrier issues.

This abstract reviews the characteristics and health risks associated with polycystic ovary syndrome and does not report new findings, highlighting the syndrome's multifactorial nature.

This review explores the role of Foxn1 in mammalian skin biology, discussing its influence on hair follicle function and the potential for further research to enhance understanding of epithelial differentiation.

These guidelines review the management of complications and specific forms of congenital ichthyosis and report no new results; they summarize expert and evidence-based recommendations for clinicians.

In this study, researchers observed that the sebaceous gland niche in mice allows for Wnt-induced hair follicle differentiation, unlike the non-permissive bulge.
