should not be used for this purpose.
I know it has been highly abused for glow, skin, whitening etc..But it is an absolute no.
There are many side effects like acne
dependence, thinning of skin, vessels showing from the skin etc.
There is no role of cortisone in generating new hair.

but it is a disease.
Stay away from cortisone unless prescribed by a doctor.
