research Increased Prevalence of Insulin Resistance and Metabolic Syndrome in Men With Early‐Onset Androgenetic Alopecia: A Case–Control Study

November 2025 in “Journal of Cosmetic Dermatology”

This study reported that young men with early-onset androgenetic alopecia have a higher prevalence of insulin resistance and metabolic syndrome compared to controls, suggesting that AGA may indicate underlying metabolic disturbances.

research Increased androgen bioavailability is associated with non-alcoholic fatty liver disease in women with polycystic ovary syndrome

119 citations , November 2009 in “Human Reproduction”

This study found that women with polycystic ovary syndrome have a higher prevalence of non-alcoholic fatty liver disease and increased androgen bioavailability may be involved alongside metabolic factors.

research Increased Scalp Skin and Serum 5a-Reductase Reduced Androgens in a Man Relevant to the Acquired Progressive Kinky Hair Disorder and Developing Androgenetic Alopecia

11 citations , September 1997 in “Archives of Dermatology”

Reduced androgens linked to kinky hair disorder and hair loss; 5a-reductase inhibitors may help.

research Increased androgen receptor messenger RNA in frontal-parietal hair follicles of women with androgenetic alopecia

6 citations , January 2013 in “Genetics and Molecular Research”

This study found that women with androgenetic alopecia demonstrated higher androgen receptor gene expression compared to controls, with a correlation found between higher AR expression and fewer CAG repeats in the AR gene.

research Increased Androgen Binding Capacity in Sebaceous Glands in Scalp of Male-pattern Baldness

51 citations , January 1989 in “Journal of Investigative Dermatology”

This study found that sebaceous glands in bald scalp have greater androgen binding affinity and capacity than those in hairy scalp, possibly contributing to the androgenic response seen in male pattern baldness.

community Increased efficacy of daytime low-dose oral minoxidil dosing for androgenetic alopecia: a retrospective study

4 upvotes 6 days ago

Daytime low-dose oral minoxidil may be more effective for treating androgenetic alopecia. Some users experience dizziness and headaches when taking it at night.

community Has anyone powered through the creatine shedding (via increased androgen receptor sensitivity) and stabilized?

9 upvotes 1 year ago

Creatine may cause increased hair shedding due to androgen receptor sensitivity, despite limited evidence. The user is using dutasteride and minoxidil and seeks advice on whether shedding will stabilize, with suggestions including GHK-Cu and RU58841.

community Minoxidil is able to suppress androgen receptors or increase aromatase effect. Blood test in pictures.

in Minoxidil 6 upvotes 4 years ago

A 24-year-old male experienced an increase in estradiol levels and symptoms like gynecomastia and excessive sweating after using Minoxidil for hair loss. His estradiol levels decreased after he stopped using Minoxidil.

community Experienced Increased Shedding After Switching from Dutasteride to Finasteride, Also Using Topical Anti-Androgen and Minoxidil

in General 84 upvotes 1 year ago

The user switched from Dutasteride to Finasteride and experienced increased hair shedding. They are also using a topical anti-androgen and Minoxidil.

community What actually causes hair loss / androgenic alopecia?

in Chat 8 upvotes 1 year ago

DHT sensitivity at the scalp increases with age, contributing to androgenic alopecia. Treatments like Minoxidil, finasteride, and RU58841 are discussed for managing hair loss.

learn Finasteride

Popular 5-alpha reductase inhibitor that lowers DHT, taken as a pill or used topically

Does hair strand thickness decrease in men with androgenic alopecia? Can finasteride help restore it? Androgenic alopecia thins hair strands by miniaturizing follicles. The pivotal finasteride trials (1,553 men, 1 mg/day, two years) report increased hair counts and improved assessed appearance, but they measured density, not the diameter of individual strands, so the effect on thickness itself is not established.
Is Finasteride unbeatable or are there equally powerful alternatives? Finasteride has the longest record of trial evidence in male androgenetic alopecia; in pooled 24-week trials dutasteride increased hair counts more, and minoxidil, topical finasteride, PRP, LLLT and microneedling have supporting studies. Regulators warn that finasteride can cause sexual side effects, depression and suicidal thoughts that may persist after stopping, its label also lists breast, semen and other physical effects, and dutasteride now carries a precautionary mood warning; both are prescription-only, and dutasteride and oral minoxidil are off-label for hair loss.

learn Minoxidil

Vasodilator used on the scalp and, at low doses, as a tablet

learn Adenosine

Molecule the body uses for energy, used as a cosmetic hair-lotion ingredient

learn Dutasteride

5-alpha reductase inhibitor that blocks both enzyme types, a stronger DHT blocker than finasteride

learn Microneedling

Technique that makes tiny punctures in the scalp with fine needles

learn Hair Transplant

Does a hair transplant increase hair density? A hair transplant can improve density, but results vary by individual factors.

learn Vascular Endothelial Growth Factor

Are there risks or side effects associated with treatments that increase Vascular Endothelial Growth Factor (VEGF)? In a VEGF gene-therapy trial for leg artery disease, raising VEGF caused more leg swelling, and excess VEGF drives leaky, abnormal vessels in mice and in eye disease. No long-term studies have tested the safety of treatments that raise VEGF in the scalp.

learn vitamin b2

Can a deficiency in Vitamin B2 cause scalp irritation or increased hair shedding? Severe vitamin B2 deficiency can cause seborrheic-dermatitis-like skin changes, according to the NIH and WHO. It is rare in well-nourished people, and reviews do not identify it as a common cause of hair shedding.
