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 Clinical Trial: N-Acetyl-Cysteine for Treatment of AGA in Men

Collagen supplements, often combined with L-cysteine, are reported to thicken hair but are not sufficient for preventing hair loss. Users also mention using other treatments like minoxidil, Nizoral, and dermarolling for hair regrowth.

community Can amino acids help with AGA

4 upvotes 2 years ago

Amino acids like lysine, methionine, and cysteine may help with androgenetic alopecia when taken in high doses along with a DHT blocker. Users discuss combining these with treatments like Minoxidil, finasteride, and RU58841.

learn L-cysteine

What is L-cysteine, and why is it often included in hair growth supplements? Cysteine is a building block of keratin, the main protein in hair. Whether cysteine supplements help hair in people who eat enough protein is unproven.
Can taking L-cysteine orally really strengthen hair from the inside? No verified study shows that L-cysteine on its own strengthens hair. The one controlled trial found tested a multi-ingredient supplement in women with shedding and did not measure hair strength.
Does L-cysteine work better alone or when combined with other vitamins and minerals? Studies have only tested cysteine inside multi-ingredient supplements, so its effect alone, and whether combinations work better, is unknown.
