Testosterone can slow down hair growth when combined with certain cells from bald scalps, and this effect can be blocked by an androgen receptor blocker.
The post and conversation are about the user's high testosterone levels and their worsening hair loss despite trying various treatments. They are considering using low doses of anti-androgens to lower their testosterone levels as a potential solution.
Topical estradiol may help with hair loss but can have systemic effects, like reduced testosterone production. Using estrogen blockers can have negative side effects, such as joint pain and reduced sex drive.
A female experiencing hair loss while on testosterone replacement therapy is using oral Minoxidil, Spironolactone, and finasteride, but still losing hair. Suggestions include switching to dutasteride, using topical anti-androgens, and reducing Nizoral shampoo use to prevent scalp dryness.
RU and Pyri block androgen receptors to prevent hair loss but may also hinder hair regrowth since they prevent testosterone, which can stimulate hair growth, from binding to these receptors. The user is questioning if this understanding is correct.
A 20-year-old saw significant hair regrowth after 9 months of using DHT blockers (finasteride and dutasteride) and 6 months of hormone replacement therapy (HRT) with estradiol. The regrowth is attributed to low testosterone and high estradiol levels, without using Minoxidil.
