0515 The effect of topical tretinoin use on topical minoxidil efficacy in androgenetic alopecia: A clinical review

Tretinoin can enhance the effects of topical minoxidil for hair loss, with Altreno recommended for its less irritating formula. Users suggest applying tretinoin first, waiting 20 minutes, then applying minoxidil or finasteride.

The conversation discusses using tretinoin as an additional treatment for hair loss alongside minoxidil, with plans to test its effectiveness by applying it to only one side of the scalp. The user intends to start this experiment after using minoxidil for a year.

Minoxidil 5% combined with 0.01% tretinoin may be as effective as using minoxidil twice daily. Users discuss switching to oral minoxidil for consistency, with concerns about side effects.

Tretinoin may enhance minoxidil absorption, potentially improving hair regrowth when combined with microneedling. Users discuss various treatments like minoxidil, finasteride, dutasteride, and microneedling, with mixed results and concerns about side effects and scarring.

The user is considering using tretinoin with minoxidil to enhance its effectiveness for hair loss, as oral minoxidil and finasteride aren't meeting expectations. They also mention ketoconazole topical as a potential scalp treatment.

The conversation discusses the effectiveness of oral minoxidil versus topical minoxidil with tretinoin for hair regrowth, with some users suggesting oral minoxidil might be more effective for non-responders to topical treatments. Concerns about side effects and the role of enzymes in activating minoxidil are also mentioned.
