research Plasma C19 Steroid Sulfate Levels and Indices of Androgen Bioavailability in Female Pattern Androgenic Alopecia
Women with female pattern hair loss have higher levels of certain androgens, suggesting increased androgen exposure to hair follicles.
research Platelet-Rich Plasma and Stem Cells for Hair Growth: A Review of the Literature
Platelet-Rich Plasma and stem cell therapy can increase hair count and density, but the best method for preparation and treatment still needs to be determined.
research Effects of the Anti-Androgen Finasteride on 5α-Reduction of Androgens in the Presence of Progesterone in Human Gingival Fibroblasts: Modulatory Actions of the Alkaline Phosphatase Inhibitor Levamisole
Finasteride reduces testosterone conversion, progesterone lessens this, and levamisole enhances finasteride's effect.
research Light Microscopic Hair Abnormalities in Children: Retrospective Review of 119 Cases in a 10-Year Period
Over half of the children had abnormal hair under a microscope, with many having genetic hair conditions.
research Evaluation of Biophysical Skin Parameters and Hair Changes in Patients with Acne Vulgaris Treated with Isotretinoin, and the Effect of Biotin Use on These Parameters
Biotin supplementation during isotretinoin treatment for acne may help maintain skin hydration and improve hair growth.
research Melasma and Endocrine Disorders
Melasma is a skin condition linked to female hormones, genetics, UV exposure, and certain medications, but not to pituitary, adrenal, or thyroid diseases.
research Major Approaches of Molecular and Physiopathological Mechanisms for Hormonal Treatment of Melasma: A Systematic Review
Estrogens and progesterone are key in regulating melasma pigmentation.
research Finasteride and Dutasteride for the Treatment of Male Androgenetic Alopecia: A Review of Efficacy and Reproductive Adverse Effects
Finasteride and Dutasteride can improve hair growth in male baldness but may cause temporary sexual dysfunction and possibly affect fertility.
research Disturbance of the Circadian System in Shift Work and Its Health Impact
Shift work disrupts the body's natural clock, leading to health problems.
research A Recently Characterized, Underdiagnosed Cause of Female Androgenetic Alopecia and Polycystic Ovarian Syndrome: Non-Classical 21 Hydroxylase Deficiency
Non-classical 21 hydroxylase deficiency is an underdiagnosed cause of female hair loss and polycystic ovarian syndrome.
research The Current and Emerging Role of Statins in the Treatment of Polycystic Ovary Syndrome: The Evidence to Date
Statins may help treat PCOS by lowering androgen levels and improving cholesterol.
research Expression of an Olfactomedin-Related Gene in Rat Hair Follicular Papilla Cells
FP-1 is a key protein in rat hair growth, active only during the growth phase.
research The Effect of Topical Minoxidil on Hair Follicular Cycles of Rats
Minoxidil speeds up hair growth in rats without prolonging growth phase.
research Effect of Retinoids on Follicular Cells
Retinoids can change the hair growth cycle by extending the growth phase and shortening the rest phase.
research Influence of Prostaglandin F2α and Its Analogues on Hair Regrowth and Follicular Melanogenesis in a Murine Model
Prostaglandin F2alpha and related compounds can increase hair growth and darken hair in mice.
research Cyclosporin A-Induced Hair Growth in Mice Is Associated with Inhibition of Calcineurin-Dependent Activation of NFAT in Follicular Keratinocytes
Cyclosporin A helps mice grow hair by blocking a specific protein activity in skin cells.
research Eyebrow Restoration: The Approach, Considerations, and Technique in Follicular Unit Transplantation
Successful eyebrow restoration can be done using careful hair transplant techniques and choosing the right patients.
research Targeted Elimination of Follicular Label-Retaining Cells by Photo-Induced Cell Killing Caused a Defect in Follicular Renewal in Mice
Killing specific cells in hair follicles can lead to hair growth problems in mice.
