This study found that sebum free fatty acids may enhance the antibacterial defense of human sebaceous glands by upregulating the expression of the antimicrobial peptide hBD-2, potentially aiding in acne treatment.

In this study, isolated human hair follicles maintained prolonged growth and consistent DNA and keratin synthesis patterns in a fully defined medium for at least 9 days while preserving in vivo-like morphology.

In this study, minoxidil sulphate was observed to significantly increase DNA synthesis in cultured human hair follicles in a concentration-dependent manner.

This study found that a serum-free DMEM-F12 medium with 45% oxygen best supports in vitro development and differentiation of human fetal skin, closely mimicking the in vivo state.

Mouse hair can regrow in a special lab setup without serum.

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 study found that a serum-free culture system supported hair growth from follicles responsive to calcium, glucose, and amino acids, with insulin enhancing the growth, while other factors had no effect.

This study found that variations in sleep patterns, free testosterone, and 5-alpha-reductase type 1 activity are associated with changes in sebum excretion in women, which may contribute to variability in acne studies.

This chapter reviews the methodology for isolating and differentiating CD34+ HAP stem cells into neural cells, but provides no new research results.

This study found that serum-free expanded hair follicle mesenchymal stem cells (hfMSCs), derived from hair plucking, significantly improved cartilage repair in a murine model despite minimal engraftment, suggesting their effectiveness through a paracrine mechanism.

This study found that DermaCult™ Keratinocyte Expansion Medium allows for significantly extended growth of human epidermal keratinocytes while maintaining their differentiation potential.

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.

In this study, researchers established a model using Mongolia Sheep hair follicles to investigate growth mechanisms, noting that adding insulin and hydrocortisone helped maintain follicle shape during extended culture.

In this study, elevated serum levels of aldosterone and free testosterone, along with increased androgen and aldosterone receptor levels, were associated with early-onset androgenetic alopecia in female patients.

This study found that women with hair loss had significantly higher free testosterone levels compared to those without hair loss.

This study found that patients with hidradenitis suppurativa had significantly higher levels of cell-free DNA in their serum compared to healthy controls, suggesting its potential as a biomarker for the disease.

This study found that patients with alopecia areata had significantly higher levels of circulating DNA for certain cytokines compared to healthy controls, suggesting that increased circulating DNA may be linked to hair follicle damage in these patients.

This study found that 9 out of 12 women with acne or alopecia showed subjective improvement with finasteride treatment despite having normal free testosterone levels, suggesting a potential role of 5alpha-reductase activity.

This study found that conditioned media from SHED stem cells cultured in STK2 media significantly stimulated hair growth in mice more effectively than media from HFSCs.

This study found that serum PSA levels are higher in hirsute women and can be significantly reduced by antiandrogen treatment, suggesting PSA as a marker of androgen action in females.

In this study, oral finasteride therapy was associated with decreased DHT levels and improved hair loss severity in young male AGA patients, while hormonal changes influenced the curative effect.

In this study, distinct metabolic profiles were identified in women with PCOS, suggesting potential biomarkers for diagnosis based on changes in lipid and androgen metabolism.

This abstract reviews testosterone supplementation with and without a dual 5α-reductase inhibitor on fat-free mass in men with suppressed testosterone production and reports no new research findings.

In this study, correlations between urinary and serum androgen metabolites were examined in girls aged 6-13, revealing that summed urinary metabolites strongly correspond with circulating androstenedione and testosterone levels, though individual variations depend on participant characteristics such as age and body measurements.

In this study of hirsute women, researchers found that correlations between hirsutism and hyperandrogenism were observed only in patients with a low LH/FSH ratio.

This study found that patients with androgenetic alopecia had increased oxidative stress and microinflammation, contributing to hair loss, due to elevated levels of specific serum biomarkers compared to controls.

Among women with androgenetic alopecia, this study observed that using Jet Peel™ with JetCare® serum led to significant trichoscopic changes, high satisfaction, and good safety after five weeks, suggesting it as a viable additional treatment option.

This research describes how herbal hair serums, containing natural components like pomegranate peel and aloe vera, can support hair health by nourishing the scalp, stimulating follicles, and enhancing hair strength and shine, aligning with growing interest in herbal and chemical-free personal care products.

This study reviews the benefits of herbal hair serums, highlighting their antioxidant and anti-inflammatory properties from natural ingredients like pomegranate peel and aloe vera, which nourish the scalp and promote healthy hair growth while improving hair strength and texture.
