D-chiral biomaterial scaffolds enhance tissue and hair regeneration by activating the body's immune system.

In this study, the application of Dr. SKS Hair Booster Serum, containing micronutrients and multivitamins, significantly improved hair density and reduced hair fall in 1,000 patients with androgenetic alopecia over six months, with no major adverse events reported and 95% patient satisfaction.

This study found that a new quercetin-loaded self-nanoemulsifying drug delivery system improved quercetin bioavailability by 149.8% compared to its suspension in rats.

This review discusses valproic acid as a common antiseizure medication associated with alopecia and highlights the need for its inclusion in relevant medical guides, without presenting new clinical findings.

This study observed that vitamin D receptor knockout mice exhibit impaired epidermal differentiation and progressive hair loss, suggesting the importance of the vitamin D receptor in normal skin and hair follicle development.

This study found that vitamin D receptor activation in primary keratinocytes can occur independently of the 1,25-dihydroxyvitamin D₃ ligand, likely through interaction with retinoid X receptors.

This study observed that Epigallocatechin-3-gallate (EGCG) can inhibit phosphorylation of STAT1 and reduce a specific subset of immune cells in vitro and ex vivo, suggesting a potential role in maintaining immune privilege in alopecia areata.

This study suggests that StemMACS MSC Expansion Media is more suitable than PowerStem MSC1 media for expanding therapeutic adipose-derived mesenchymal stem cells, with less expression of negative markers and better chromosomal stability.

This case report documents a female toddler with novel compound heterozygous mutations in the VDR gene causing hereditary 1,25-dihydroxyvitamin D-resistant rickets, expanding the known mutation spectrum for this disease.

This study found that severe forms of alopecia areata showed increased activated T cells and natural killer cells, which decreased after corticosteroid treatment, correlating with disease activity and hair regrowth.

This study suggests that autoimmune dysregulation involving HLA-DR+ T and NK cell subsets may contribute to severe patchy alopecia areata and alopecia universalis, with normalization seen after betamethasone treatment.

In this study of clinical-grade ADMSCs, researchers found that cells expanded in PowerStem MSC1 media exhibited increased negative marker expression, chromosomal abnormalities, and signs of senescence compared to those cultured in StemMACS MSC Expansion Media, suggesting that the latter is more suitable for therapeutic applications.

This study reported a significant increase in global online searches for finasteride and its possible sexual side effects, particularly after the FDA's 2012 warning.

This review discusses the regulation and function of vitamin D and its receptor in skin cells, highlighting their roles in processes such as proliferation inhibition, differentiation, and innate immunity, but reports no new results.

This study found that the effects of the vitamin D receptor on hair follicle cycling in mice are independent of its ability to bind a hormone, with specific domain mutations influencing hair regrowth outcomes.

In this study, researchers observed vitamin D insufficiency in many patients with Alopecia Areata, suggesting its potential role in managing this autoimmune condition.

This study discusses the potential association between low vitamin D levels and insulin resistance, suggesting that vitamin D deficiency may contribute to disorders like obesity and diabetes, but emphasizes the need for further research to confirm these links.

This review suggests that decreased serum 25-hydroxyvitamin D levels may play a role in different types of non-scarring alopecia, but further studies are needed to explore vitamin D supplementation as a therapeutic option.

This study suggests that impaired VDR signaling in mice leads to dysregulated Ddit4 expression, impacting hair cycle progression and wound healing.

In this study, alopecia areata and vitiligo patients had significantly lower serum BDNF and vitamin D levels, which were inversely associated with depression and quality of life, suggesting a potential combined role in the development of depression.

This study found no significant association between premature hair graying and serum ferritin or vitamin D levels in young adult males at Universitas Sumatera Utara.

This article highlights a lack of published data on vitamin D deficiency prevalence among individuals with central centrifugal cicatricial alopecia, despite its known link to other forms of hair loss.

This study found that adequate vitamin D status is necessary for metformin to effectively reduce prolactin levels in men with iatrogenic hyperprolactinemia, while improvements in glycemic control were observed across all vitamin D groups.

This study showed that vitamin D receptor gene-deficient rats exhibit hair loss and skin abnormalities due to differences in gene and protein expression patterns, while ligand-independent VDR action is crucial for normal hair cycle maintenance and skin formation.

This study found that among women with PCOS, the FokI CC genotype of the VDR gene may offer protection against acne and seborrhea, while the VDR-TaqI dominant genotype is associated with reduced oxidative stress.

This review highlights the crucial role of vitamin D signaling in epidermal stem cells during skin wound healing, emphasizing its distinct functions from calcium metabolism and its importance in genomic regulation mediated by the vitamin D receptor.

This review reports that vitamin D plays an important role in hair follicle development, with a negative correlation observed between serum vitamin D levels and female pattern hair loss, suggesting further research is needed before recommending vitamin D as a treatment.

In this study, researchers found a significant relationship between mid-luteal progesterone levels and 25-hydroxy vitamin D levels in infertile patients, suggesting that about 20 ng/mL of vitamin D may be necessary to trigger ovulation or support progesterone secretion.

This study found that at Dr. Cipto Mangunkusumo National General Hospital in Jakarta, alopecia areata was the most prevalent hair disorder, followed by alopecia androgenetic and telogen effluvium, each with distinct socio-demographic profiles.
