The user is asking if caffeine topicals are effective for hair growth, noting they already use Minoxidil and finasteride. They are unsure if caffeine topicals are beneficial or a waste of money.
Quitting vaping significantly reduced hair loss for a user who was a heavy vaper and also taking finasteride. Some participants suggest nicotine's vasoconstrictive properties may worsen hair loss, while others share personal anecdotes of hair improvement after quitting smoking or vaping.
Bryan Johnson uses a custom hair loss treatment that includes topical finasteride, minoxidil, azelaic acid, diclofenac, tea tree oil, rosemary oil, ginkgo biloba, biotin, and melatonin, which have shown varying degrees of effectiveness with minimal side effects. He also undergoes PRP and laser therapy, and has tried dutasteride mesotherapy.
Alcohol-based minoxidil absorbs better but can cause irritation; non-alcohol-based is gentler. Topical dutasteride shows promise but needs more research; low-dose oral minoxidil (0.25 mg/day) is effective with fewer side effects. Ingredients like Procapil, Redensyl, caffeine, and Anagain in shampoos have limited evidence; ketoconazole shampoo can help when used 2-3 times a week with other treatments.
