Scalp Aches and Feels Bruised After Using Minoxidil

Dr Rassman,

I am in my late twenties and my hair has shown signs of thinning out on top. I have been using minoxidil (5%) for 6 months now and, although there has been some benefit, i have noticed my scalp aches and feels bruised in several areas. My hair feels it has been pulled at when i run my fingers through it. It doesn’t feel right so i am considering stopping treatment. I have previously had this sensation with minoxidil after a similar amount of time and stopped treatment but restarted after a few months. Do you have any idea what may be causing these sensations?

You may have sensitivity associated with topical minoxidil and you may not be a good candidate for its use.
