Adding tretinoin to minoxidil may help non-responders but likely won't improve results for those already responding to minoxidil. The user plans to try tretinoin with minoxidil and finasteride to see if it enhances hair regrowth.
Finasteride prevents further hair loss by blocking DHT, while minoxidil stimulates hair growth by prolonging the active phase of hair follicles. Stopping minoxidil can lead to loss of regrownhair because finasteride does not address the same growth mechanism.
Individuals with oily scalps, dandruff, and diffuse thinning hair loss who have managed to either halt the loss or regrow their hair by using topical finasteride and minoxidil as well as microneedling and ketoconazole 2% shampoo.
Stopping hair loss treatments like finasteride and minoxidil can result in losing regrownhair, highlighting the importance of consistent use. Restarting these treatments may cause temporary shedding, but hair can regrow with continued use.
