I am currently using a 2% minoxidil solution for my thinning hair, but it is still falling out! most likely from hormones (I'm 54) but recently read an email regarding a solution for hair growth and I inquired about the active ingredient since I'm already using what supposedly works. They replied, .025% treatinoin and minoxidil, 2%. I've tried to research this treatinoin and it seems more of a cure for acne. This company requested that I purchase 3 of their formulated hair growth solutions except it's quite expensive monthly...about $90. or more. Yet I can not find that this a cure for thinning hair, hair loss. Can you confirm if this is wise to purchase. Is there anything that really works for thinning hair?
