Why do some hairs come back from Finasteride, but others only come back with Minoxidil?

12/26/2025

Hair loss may be linked to blood flow issues, but DHT is considered the main cause. Treatments used include finasteride, RU58841, minoxidil, vitamin D3, microneedling, and dutasteride, but hair loss persists.

The conversation discusses skepticism about the effectiveness of scalp tension theory and scalp massagers for hair regrowth, contrasting it with treatments like finasteride and minoxidil, which have more user-reported results. Participants question the belief in scalp tension theory, suggesting it may be a marketing tactic, while others argue for a multifactorial approach to hair loss.

Minoxidil helps hair growth by increasing blood flow and prolonging the growth phase, but it doesn't address the root cause of hair loss, such as DHT sensitivity. Finasteride can help maintain some gains by blocking DHT, but stopping Minoxidil often leads to hair loss because the new hairs are dependent on it.

Minoxidil effective for regrowth but causes dryness; finasteride stops hair loss but may affect hormones; dutasteride powerful but reduces libido; RU58841 thickens hair but expensive and risky; dermarolling improves blood flow and results; aminexil overrated and not effective. Dermarolling beneficial with both minoxidil and finasteride.

Minoxidil may suppress androgen activity in hair follicles, potentially aiding in hair growth and prostate cancer treatment. Users discuss the effectiveness of minoxidil and finasteride for hair maintenance and regrowth, with some preferring topical applications over oral due to safety concerns.
