Does isopropyl alcohol kill or denature minoxidil and finasteride?

It is safe to mix topical finasteride with minoxidil together in their original preparations for hair growth with androgenic alopecia. Because minoxidil is a vasodilator, studies show that it aides in penetration of the topical finasteride for hair growth. When it comes to hair loss, you need a formal evaluation to see what type of hair loss you may have. It's best to do a full hormonal workup for internal optimization, evaluate it with a dermatoscope, and consider scalp biopsies or scrapings to rule out any stress related, inflammatory, autoimmune or infectious causes of hair loss. In general, most people with early hair loss have telogen (stress related) and/or androgenetic (normal aging) and both can be treated with in office treatments like steroid injections, PRP/Acell, Exosomes and at home treatments like oral medications like Finasteride or Spironolactone, oral vitamins like Viviscal, topical exfoliating sprays like Restorsea, and weekly growth factors like anteagemd. See an expert for an evaluation. If hair loss is significant it may requires hair transplant (follicular unit translation).
