How long does it take to cure alopecia using ayurveda methods?

It won't happen: Don't expect results. If you have male pattern baldness, and you want to treat it, get with a mainstream physician for medical or transplant Rx. If it's alopecia areata or telogen effluvium, it may remit on its own. Many men embrace their masculinity and genetics and focus on fitness -- do this and you'll look and feel great regardless of where there is and isn't hair.
