research Overexpression of Aldo-Keto Reductase 1C3 in LNCaP Cells Diverts Androgen Metabolism Towards Testosterone Resulting in Resistance to the 5α-Reductase Inhibitor Finasteride
Too much AKR1C3 enzyme causes resistance to finasteride by increasing testosterone.
research Human Type 3 5α-Reductase Is Expressed in Peripheral Tissues at Higher Levels Than Types 1 and 2 and Its Activity Is Potently Inhibited by Finasteride and Dutasteride
Type 3 5α-reductase is more common and finasteride and dutasteride strongly inhibit it.
research Finasteride, 1 Mg Daily Administration on Male Androgenetic Alopecia in Different Age Groups: 10-Year Follow-Up
Finasteride effectively increases hair growth in men with AGA, works better for those over 30, and may cause some side effects.

research Hirsutism
Hirsutism is excessive male-pattern hair growth in women, often caused by hormonal imbalances, and requires ongoing treatment to manage.
research Acquired Scalp Alopecia: A Review
Early diagnosis and treatment are crucial for preventing permanent hair loss in various scalp conditions, and while new treatments are promising, more research is needed to evaluate their effectiveness.
research Guidelines of Care for Androgenetic Alopecia
Treat genetic hair loss early with FDA-approved medications and consider hair transplantation.
research Local and Systemic Reduction by Topical Finasteride or Flutamide of Hamster Flank Organ Size and Enzyme Activity
Topical finasteride and flutamide reduce gland size and enzyme activity, with flutamide being more potent, potentially treating acne, seborrhea, hirsutism, and androgenic alopecia.
research Aromatase Deficiency in a Male Patient: Case Report and Literature Review
A male with aromatase deficiency improved bone health with estradiol treatment.
research Biosynthesis of Dihydrotestosterone by a Pathway That Does Not Require Testosterone as an Intermediate in the SZ95 Sebaceous Gland Cell Line
Dihydrotestosterone can be made from dehydroepiandrosterone in skin cells without needing testosterone.
research Side Effects of 5-Alpha Reductase Inhibitors: A Comprehensive Review
5-alpha reductase inhibitors slightly increase the risk of sexual and mood side effects, and breast growth in men.
research Global Photographic Assessment of Men Aged 18 to 60 Years with Male Pattern Hair Loss Receiving Finasteride 1 mg or Placebo
Finasteride significantly improves hair growth but may cause sexual side effects.
research Leydig Cell Hyperplasia and Adenomas in Mice Treated with Finasteride, a 5α-Reductase Inhibitor: A Possible Mechanism

research Minoxidil Increases 17β-Hydroxysteroid Dehydrogenase and 5α-Reductase Activity in Cultured Human Dermal Papilla Cells from Balding Scalp
Minoxidil boosts enzymes that help hair growth.
research Azasteroids as Inhibitors of Testosterone 5α-Reductase in Mammalian Skin
Certain 4-azasteroids are effective at blocking the enzyme that processes testosterone in human skin and could help treat acne, excessive hair growth, and male pattern baldness.
research Patients With a Large Prostate Show a Higher Prevalence of Androgenetic Alopecia
Large prostate links to more hair loss, but age of onset doesn't affect it.
research Understanding and Addressing Hair Disorders in Transgender Individuals
Hormone therapy affects hair growth in transgender individuals, with testosterone potentially causing hair loss in trans men and estrogen reducing facial/body hair in trans women; treatment options vary.
