Skin disorder like red, scaly patches on your scalp and seborrheic dermatitis can flare up from time to time, leaving the scalp bumpy, flaky and itchy. If either condition strikes you, consult your dermatologist immediately. Any type of your skin disorder on your scalp can make you bald. These conditions cause inflammation which – like sunburn – floods your scalp with superoxide, which causes follicle to eject hair permanently. And again, the hair that regrows may not be thick.
Do not make the mistake of simply treating these conditions with an over-the-counter shampoo.
