Dermatitis
"Betamethasone Lotion 0.1% for itchy scalp.  I used this for over 40 years for scalp control.  Then a couple years ago, the price shot up - over 10X the normal price which is rediculous.  So my doctor turned me on to a stronger type called Clobetasol Propionate .05% topical.  This works even better than my older stuff and my insurance covers this."
