I'm using minoxidil 5% to treat my hair fall. Should I shampoo my head daily, or once every two days?

You did not state your
sex, something that has great value when answering this type of question. I
always start off with the drug finasteride for one year in men. Many men under 30, will stop or reverse the thinning that
occurs with genetic balding with the drug finasteride. I also always perform
bulk measurements with an instrument called HAIR CHECK which is a good way to
determine just how much thinning you have that you can not see. Once this test
is done and you have gone a year, I often repeat the test as it gives an
excellent measurement on what happened to your hair over the year. If it got
better and some of the thinning reversed, maybe you won't need a transplant and
that is the goal that you should look to do. Of course, a good doctor is
critical to this course.If you are a woman, then you absolutely need a doctor to make the diagnosis and treating your hair loss with minoxidil without a diagnosis will probably get you no where.
