research Hair Growth Defects in Insig-Deficient Mice Caused by Cholesterol Precursor Accumulation and Reversed by Simvastatin
Mice lacking Insig proteins had hair growth problems due to cholesterol buildup, but this was fixed by the drug simvastatin.
research Sterol Intermediates of Cholesterol Biosynthesis Inhibit Hair Growth and Trigger an Innate Immune Response in Cicatricial Alopecia
Cholesterol-related compounds can stop hair growth and cause inflammation in a type of scarring hair loss.
research Pharmacological Inhibition of DGAT1 Induces Sebaceous Gland Atrophy in Mouse and Dog Skin While Overt Alopecia Is Restricted to the Mouse
Blocking DGAT1 reduces oil gland size in mice and dogs, but only mice experience hair loss.
research Aromatase inhibitor–induced hair loss in two adolescents
Two teenage boys lost hair after taking a drug for growth, which was not a known side effect for kids.
research Role of cholesterol sulfate in epidermal structure and function: Lessons from X-linked ichthyosis
Cholesterol sulfate buildup due to a genetic mutation disrupts the skin barrier, leading to the scaling skin seen in X-linked ichthyosis.
research Cholesterol homeostasis: Links to hair follicle biology and hair disorders
Cholesterol balance is important for hair health, and problems with it can lead to hair loss conditions.
research Effects of Finasteride (MK-906), a 5α-Reductase Inhibitor, on Circulating Androgens in Male Volunteers*
Finasteride safely lowers DHT levels without affecting testosterone.
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 Inhibition of 5α-Reductase, IL-6 Secretion, and Oxidation Process of Equisetum debile Roxb. ex Vaucher Extract as Functional Food and Nutraceuticals Ingredients
Equisetum debile extract, especially the ethyl acetate type, may be a promising natural ingredient for anti-hair loss products.
research 5α-Reductase type 1 inhibition of Oryza sativa bran extract prepared by supercritical carbon dioxide fluid
Rice bran extract might help prevent hair loss.
research Localisation and regulation of cholesterol transporters in the human hair follicle: mapping changes across the hair cycle
Cholesterol transport in hair follicles decreases from growth to regression phase.
research The ‘bald’ phenotype (androgenetic alopecia) is caused by the high glycaemic, high cholesterol and low mineral ‘western diet’
Western diet may cause male pattern baldness; low glycemic diet with magnesium could help.
research Tofacitinib: The selected selective JAK inhibitor in paediatric dermatology
Tofacitinib may be safe and effective for treating certain skin conditions in children.
research Aromatase inhibitor therapy and hair loss among breast cancer survivors
Aromatase inhibitor therapy for breast cancer increases the risk of hair loss and thinning.
research Consequences of steroid-5α-reductase deficiency and inhibition in vertebrates
Lack or blocking of SRD5a, a key component in hormone creation, can lead to conditions like pseudohermaphrodism and affect hair growth, bone mass, muscle strength, and reproductive health. More research is needed on its regulation from fertilization to adulthood.
research Effect of Testosterone Supplementation With and Without a Dual 5α-Reductase Inhibitor on Fat-Free Mass in Men With Suppressed Testosterone Production
Testosterone's muscle-building effects do not require its conversion to DHT.
research Outcome of long-term treatment with the 5α-reductase inhibitor finasteride in idiopathic hirsutism: clinical and hormonal effects during a 1-year course of therapy and 1-year follow-up
Finasteride effectively reduces hair growth in women with idiopathic hirsutism, but requires careful contraception during treatment.
research Overexpression of aldo-keto reductase 1C3 (AKR1C3) 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 Treatment of male rats with finasteride, an inhibitor of 5alpha-reductase enzyme, induces long-lasting effects on depressive-like behavior, hippocampal neurogenesis, neuroinflammation and gut microbiota composition
Finasteride treatment in male rats causes long-lasting effects on depression-like behavior, brain cell growth, inflammation, and gut bacteria composition.
research FCE 28260, a new 5α-reductase inhibitor: In vitro and in vivo effects
FCE 28260 is a stronger and longer-lasting inhibitor of 5α-reductase than finasteride, which may make it a better treatment for certain medical conditions.
research The 5α-reductase inhibitor finasteride increases suicide-related aggressive behaviors and blocks clozapine-induced beneficial effects in an animal model of schizophrenia
Finasteride raises suicide-linked aggression and stops clozapine's positive effects in schizophrenia animals.
research Oral Testosterone With and Without Concomitant Inhibition of 5α-Reductase by Dutasteride in Hypogonadal Men for 28 Days
Taking oral testosterone with or without dutasteride increases testosterone levels and could be an effective treatment for low testosterone.

Finasteride may cause kidney damage.
research Steady-state pharmacokinetics of oral testosterone undecanoate with concomitant inhibition of 5α-reductase by finasteride
