1744 citations , August 2006 in “The Journal of Clinical Endocrinology and Metabolism”

This review discusses definitions of polycystic ovary syndrome and reports no new clinical results; the authors support using modified 1990 NIH criteria and acknowledge ongoing evolution as research advances.

research Trichoscopy criteria for diagnosing female androgenic alopecia.

5 citations , May 2008 in “Nature Precedings”

In this study, trichoscopy was used to diagnose female androgenic alopecia with 92% specificity by identifying specific hair and scalp patterns.

research Diagnostic and grading criteria for androgenetic alopecia using dermoscopy

March 2024 in “Skin research and technology”

This study reported that newly established dermoscopic diagnostic and grading criteria for androgenetic alopecia are highly accurate, with sensitivity and specificity at 98.3% and 96.7%, respectively.

research Dermoscopy in female androgenic alopecia: Method standardization and diagnostic criteria

129 citations , January 2009 in “International Journal of Trichology”

This study found that trichoscopy criteria can distinguish female androgenic alopecia from chronic telogen effluvium, with specific features achieving 98% diagnostic specificity.

research The Androgen Excess and PCOS Society criteria for the polycystic ovary syndrome: the complete task force report

1540 citations , October 2008 in “Fertility and Sterility”

This review discusses the definition of polycystic ovary syndrome proposed by the AE-PCOS Society Task Force, emphasizing hyperandrogenism, ovarian dysfunction, and excluding related disorders, while noting potential variations needing more research.

community Heads Up on Future Study: "Influence of Creatine Monohydrate Supplementation on Androgens and Global Hair Assessments"

22 upvotes 6 years ago

Creatine supplementation may increase DHT levels, potentially affecting hair loss. A study is examining this effect, with participants taking 5 grams of creatine daily for six months.

community Efficacy and Tolerability of N-Acetyl-Cysteine for Treatment of The Early-onset Androgenetic Alopecia in Men

26 upvotes 4 years ago

N-Acetyl-Cysteine (NAC) was found to improve hair parameters in men with early-onset androgenetic alopecia, showing increased terminal hair count and decreased vellus hair count, with good tolerability. NAC, used alone or with minoxidil, may help due to its antioxidant properties, though its effectiveness can vary among individuals.

community Female 37/F - On Meds, but no progress. Add PRP?

4 upvotes 3 years ago

A 37-year-old woman with androgenetic alopecia is using spironolactone, oral and topical minoxidil, and considering PRP therapy due to lack of progress. She is unable to obtain finasteride, dutasteride, or bicalutamide and is exploring other options like Clascoterone and RU58841.

community Hair Growth Caps and Helmets Research

32 upvotes 7 months ago

Hair growth caps and helmets using low-level laser therapy (LLLT) show potential for treating androgenetic alopecia, but more research is needed. Users often combine these devices with treatments like minoxidil and finasteride for better results.

community Summary of Procapil video by Haircafe

2 upvotes 1 year ago

Procapil is marketed as a natural hair loss treatment but lacks strong evidence and is industry-biased. Minoxidil and Finasteride are the only FDA-approved treatments for androgenetic alopecia.

learn Finasteride

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.

learn Spironolactone

Who can safely use spironolactone for hair thinning and androgen-related hair loss? Women with androgen-related hair loss can safely use spironolactone under medical supervision.

learn Argan oil

Argan oil: Is it useful for androgenic alopecia, or just for making hair look nice? Argan oil primarily improves hair appearance but lacks proven effectiveness for androgenic alopecia.

learn Metformin

Does metformin help control DHT levels that trigger androgenic alopecia? Metformin has been shown to lower circulating androgens in women with PCOS, but no published study has measured scalp DHT, 5-alpha reductase activity in the follicle, or hair density in anyone taking it — so its effect on pattern hair loss is untested, and it is not a DHT blocker.

learn Microneedling

Does microneedling help with all types of alopecia, or only androgenic alopecia? Microneedling is most effective for androgenic alopecia, with limited evidence for other types.
