Usually 5 percent Minoxidil is prescribed at most of the centres in India for almost one year. We have seen over the years that people who use it have their hair thickness improved by about 5 to 10 percent. Minoxidil increases the local blood supply of the skin thereby supplying more nutrition to the roots. The maintenance dose of Minoxidil is once or twice a week after one year. In our practice we have also seen that 10 to 15 percent people are allergic to it and they develop frequent itching redness and swelling. In such cases we advise them to not to use.
