I have started using nizoral shampoo and started using minoxidil, scalp has now however become more aggravated and is now sore to the touch. I was diagnosed with genetic hairloss, and seborrhoeic dermatitis. Will this "aggravated scalp' lead to permanent damage to hair follicles. There is no blood or scabbing of any sort just a sore scalp, very little swelling type bumps (2-3) and skin cells/ dandruff.
