Whether topical caffeine can be as effective for hair growth as minoxidil and finasteride, with various replies discussing the efficacy of these treatments and criticism of Dr. Huberman's research methods.
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.
The conversation discusses whether drinking coffee affects the hair growth benefits of Minoxidil, with one user mentioning that Minoxidil's vasodilation is stronger than caffeine's vasoconstriction, and another sharing personal experience of better hair growth after quitting caffeine while on Minoxidil.
Coffee may negatively impact hair health due to its vasoconstrictor effects, potential to increase DHT, and interference with nutrient absorption. There is no strong clinical evidence linking caffeine to hair loss or regrowth in humans, but moderation is advised.
A user suspects Ritalin is causing hair loss due to vasoconstriction and is considering trying Ginkgo Biloba after already taking a multivitamin and hair supplement. Another user mentions experiencing hair shedding with Vyvanse and Dexedrine.
