If you are experiencing thinning hair, you are not alone. Hormonal changes (peri menopause) and this brand of genetic minoxidil 5% foam isn't oily and even may give hair a little body. Yay!! The 5% says it's for men. They sell 3% for women but most women go with the stronger stuff if you research it. Play it safe & avoid chemicals if nursing or childbearing whether you're a man or woman. Essentially you'll be applying a chemical to your scalp that blocks a chemical produced in your body called DIHYDROTESTOSTERONE.. From what I understand this is what can become of excess testosterone produced by your body and tells the hair follicles to go to sleep, into a dormant phase when shedding increases and less new hair is growing as more follicles enter the androgen phase. Be careful to wash your hands after applying. A side effect I know of that it can increase the peach fuzz on your face. . Minoxidil has been around long enough, it's sold over the counter..and seems like common sense to try something rather than let hair follicles die off because if dormant long enough they will lose the blood supply, and that's it. The hair will become thinner, weaker and eventually won't grow back. Each hair strand has it's own individual blood supply… fascinating when you think about it. So this product potentially can work for both men and women. Try it for at least 3 months and take before and after photos to see if you experience less shedding and hopefully fuller, thicker hair.
