Hair regrowth from treatments like minoxidil, RU58841, and finasteride is not permanent; stopping these treatments typically results in hair loss resuming. Beard hair can become permanent with minoxidil use, unlike scalp hair, which requires ongoing treatment to maintain gains.
The conversation discusses identifying permanenthair loss and includes treatments like microneedling and biotin vitamins. The user is unsure whether the reduction in wispy hairs is due to hair revitalization or loss.
Beard hair grown with minoxidil can become permanent because it is not sensitive to DHT, unlike scalp hair, which requires ongoing minoxidil use even with DHT blockers like finasteride or dutasteride. Dutasteride reduces scalp DHT significantly but not completely, which may explain why scalp hair still needs minoxidil for maintenance.
Scalp sunburns can cause permanenthair loss, so wearing UPF hats is essential. Tretinoin and Tacrolimus users should be cautious of increased photosensitivity and potential scalp issues.
Shampoos are unlikely to cause permanenthair loss; hair loss is more likely due to male pattern baldness (MPB). The user is advised that losing hair in the shower is normal, and to avoid shampoos with sodium sulfate.
