Dutasteride and finasteride can cause changes in physical appearance, like more feminine features and increased water retention. Users report side effects such as reduced libido, weight gain, and improved skin clarity, while some notice no significant changes.
Oral minoxidil is effective for hair loss and unlikely to significantly affect collagen synthesis, making it a safe option without causing premature skin aging. Users report positive hair regrowth without noticeable skin aging.
Topical finasteride that doesn't penetrate the skin could potentially treat hair loss without side effects. Current challenges include finding a formulation that remains on the scalp without increasing blood levels.
Finasteride and minoxidil use resulted in a more youthful appearance and improved skin. There is debate about their effects on collagen and skin aging, with no solid evidence supporting significant changes due to finasteride.
