I am 45 year old, and notice a lot of thinning, and a few bald patches on the top of my hear, the 2 bald patches turn red sometimes, I went to a derm, he gave me some lotion to put on it, and after seeing hem every 3 months, he gave me a presription for propecia, but after seeing how much it cost, I decided to look on the web. that is were I see a lot of people getting procar cheaper, anyone know where to get it, without a prescription, cause my Doctor, will only give me propecia. Also is there a shampoo that will block the dht, basically any help that anyone can give me would be great. I do take biotin, and sawpalmetto, not sure why, someone told me it might help, but it hasn't yet. Please leave my any advise you might have. thanks
