research Retrospective evaluation of sex hormones and steroid hormone intermediates in dogs with alopecia
Most dogs with alopecia had higher than normal levels of certain hormones, but hair loss might not always be linked to these hormone changes.

research External genitalia abnormalities in male rats exposed in utero to finasteride, a 5α-reductase inhibitor
Finasteride exposure in pregnancy causes genital abnormalities in male rats.
research Androgen actions on the human hair follicle: perspectives
Androgens have complex effects on hair growth, promoting it in some areas but causing hair loss in others, and our understanding of this is still evolving.
research Critical Developmental Periods for Effects on Male Rat Genitalia Induced by Finasteride, a 5α-Reductase Inhibitor
Finasteride affects male rat genitalia development, causing abnormalities during specific pregnancy days.
research The effect of finasteride, a 5 alpha-reductase inhibitor, on scalp skin testosterone and dihydrotestosterone concentrations in patients with male pattern baldness.
Finasteride reduces scalp DHT levels, potentially treating male pattern baldness.
research Minoxidil increases 17β-hydroxysteroid dehydrogenase and 5α-reductase activity of cultured human dermal papilla cells from balding scalp
Minoxidil boosts enzymes that help hair growth.
research 5α‐Reductase inhibitors and prostatic disease
5α-Reductase inhibitors can help treat hair loss, acne, and prostate issues by reducing DHT levels.
research Androgenetic alopecia and hair growth promotion state of the art: Present and future
Current research explores hair growth drugs, while future research aims for personalized treatments.
research Male pattern hair loss: prevention rather than regrowth
Preventing hair loss is more effective than regrowth; oral finasteride is a realistic option.
research The hair growth promoting effect of Sophora flavescens extract and its molecular regulation
Sophora flavescens extract may help hair grow by affecting growth factors and blocking a hair-related enzyme.
research Expression of mRNA for androgen receptor, 5alpha-reductase and 17beta-hydroxysteroid dehydrogenase in human dermal papilla cells
Hair sensitivity to androgens is partly controlled by specific enzyme expressions in different hair areas.
research Effects of finasteride, a 5 alpha-reductase inhibitor, on circulating androgens and gonadotropin secretion in hirsute women.
Finasteride reduces dihydrotestosterone, increases testosterone, and may treat hirsutism in women.
research 5α-Reductase Inhibitors, Chemical and Clinical Models
Researchers developed a model to predict how well certain compounds can block an enzyme related to hair loss and prostate issues, suggesting a 50 mg dose of finasteride might be effective based on lab and body data.
research 9 Role of 5α-reductase in health and disease
5α-reductase is essential for male sexual development and its inhibitors have potential in treating various conditions related to hormone action.
research 5α‐Reductase Isozymes and Androgen Actions in the Prostate
5α‐reductase isozymes are crucial for prostate development and health, and targeting them can help prevent and treat prostate issues.
research Finasteride
Finasteride treats enlarged prostate, shrinks it, improves urination, but may cause sexual dysfunction and isn't for women or children.
research Androgen receptors and their biology
Androgen receptors are key for development and health, affecting conditions like prostate cancer and male pattern baldness.
research 5α-Reductase activity in the human hair follicle concentrates in the dermal papilla
The enzyme that changes testosterone to a stronger form is mostly found in the part of the hair follicle called the dermal papilla.
research Steroidogenic Isoenzymes in Human Hair and Their Potential Role in Androgenetic Alopecia
Steroidogenic isoenzymes may help improve treatments for common hair loss.
research The diagnosis of androgenetic alopecia in children: Considerations of pathophysiological plausibility
AGA in children needs careful diagnosis due to low androgen levels and possible other causes.
research Anti-androgen therapy in dermatology: a review
Anti-androgens are effective for female acne but less so for male-pattern hair loss, with side effects similar to birth control pills.
research Selections from current literature: androgenetic alopecia: the science behind a new oral treatment
New oral treatment, finasteride, effectively and safely treats common hair loss.
research Ethnobotany, phytochemistry and pharmacology of the Mediterranean dwarf palm (Chamaerops humilis L.)
The Mediterranean dwarf palm has medicinal, nutritional, and craft uses, but more research is needed.
research Lack of efficacy of finasteride in postmenopausal women with androgenetic alopecia
Finasteride doesn't effectively treat hair loss in postmenopausal women.
research Female pattern hair loss
Hair loss in women is genetic, diagnosed by examination and biopsy, and treated with minoxidil, finasteride, or transplantation.
research Androgens and alopecia
Male hormones, particularly DHT, are linked to male pattern hair loss, and treatments like finasteride can help, but they don't work for postmenopausal women's hair loss, which may have different causes.
research A New Look at the 5?-Reductase Inhibitor Finasteride
Finasteride treats enlarged prostate and hair loss, but may cause side effects in some patients.
research Immunohistochemical localization of types 1 and 2 5α-reductase in human scalp
The study found that two enzymes linked to hair loss are located in different parts of the scalp, supporting a common treatment's effectiveness.
research 5α-Reductase type 2 gene variant associations with prostate cancer risk, circulating hormone levels and androgenetic alopecia
A49T gene variant linked to higher prostate cancer risk, lower hormone levels, and slightly reduced balding risk.
research PNU 157706, a novel dual type I and II5α-reductase inhibitor
PNU 157706 is a more effective treatment than finasteride for conditions caused by DHT, like enlarged prostate and hair loss.
