Vitamin D is important for skin health and can help treat psoriasis, atopic dermatitis, and vitiligo.
research Hidradenitis suppurativa/Acne inversa: an endocrine skin disorder?
Hidradenitis suppurativa may be related to hormones and patients often have metabolic disorders; more research is needed to understand this connection.
research Study of gene expression alteration in male androgenetic alopecia: evidence of predominant molecular signalling pathways
Hair loss involves immune responses, inflammation, and disrupted signaling pathways.
research A Humanized Mouse Model of Hereditary 1,25-Dihydroxyvitamin D–Resistant Rickets Without Alopecia
Researchers created a mouse model of a type of rickets that does not cause hair loss.
research The Vitamin D Receptor Is Required for Mouse Hair Cycle Progression but not for Maintenance of the Epidermal Stem Cell Compartment
Vitamin D Receptor is needed for hair growth in mice but not for skin stem cell maintenance.
research Retinoid Metabolism Is Altered in Human and Mouse Cicatricial Alopecia
Altered retinoid metabolism in cicatricial alopecia suggests a balanced vitamin A diet may prevent the condition.
research The Influence of Valproic Acid and Carbamazepine Treatment on Serum Biotin and Zinc Levels and on Biotinidase Activity
Valproic acid and carbamazepine do not change biotin or biotinidase levels but may lower zinc levels, still within normal range.
research The Transient Role for Calcium and Vitamin D during the Developmental Hair Follicle Cycle
Vitamin D and calcium are essential for normal hair growth.
research Induction of osteoblastic differentiation of neural crest-derived stem cells from hair follicles
Hair follicle cells can become bone-like cells, useful for bone repair.
research Skin diseases in consequence of endocrine alterations
Hormone imbalances can cause skin diseases, and understanding these links is important for diagnosis and treatment.
research Lichen Planopilaris in Women
Women with lichen planopilaris often have thyroid disease, depression, anxiety, and may respond to treatment with slowed disease progression.
research Vitamin D and calcium signaling in epidermal stem cells and their regeneration
Vitamin D and calcium are important for skin stem cell function and wound healing.
research Erosive pustular dermatosis of the scalp: causes and treatments
A rare scalp condition mainly in older women can be treated with various alternatives to steroids, which may have fewer side effects.
research Effect of a transcriptional inactive or absent vitamin D receptor on beta-cell function and glucose homeostasis in mice
Mice without active or present vitamin D receptors maintain normal blood sugar control and islet gene expression when calcium levels are normal.
research Testosterone replacement in 49,XXXXY syndrome: andrological, metabolic and neurological aspects
Testosterone therapy improved physical and social health in a male with 49,XXXXY syndrome.
research Nongenomic effects of 1α,25-dihydroxyvitamin D 3 on cartilage formation deduced from comparisons between Cyp27b1 and Vdr knockout mice
1α,25-dihydroxyvitamin D3 directly affects cartilage growth and development.
research Prevention of Alopecia in Medical and Interventional Chemotherapy Patients
