Androgenetic alopecia is caused by DHT affecting hair growth. Finasteride and minoxidil are used to manage hair loss by blocking DHT and promoting hair growth.
Minoxidil may improve or worsen skin quality, with topical forms causing dryness and wrinkles, possibly due to alcohol content, while oral forms have fewer side effects. Some users consider using tretinoin to mitigate negative effects.
Oral minoxidil may cause dry skin and dark eye bags but doesn't significantly age the skin. Topical minoxidil is toxic to cats, and some users prefer finasteride.
Tretinoin may enhance minoxidil's effectiveness for those not responding to minoxidil alone, but it could reduce efficacy for some who are already responding to minoxidil. Tretinoin requires careful use, including skin moisturizing and sun protection due to increased sensitivity.
Microneedling for hair restoration involves daily use of a 0.3 mm device and weekly use of a 0.5 mm device. Combining microneedling with Minoxidil can enhance hair growth.
