Hi..dear Manjulatha..,
Thanks for choosing HCM..,
1) white patches on fore head..,
2types are there....Hypopigmented and Depigmented..,
a) Depigmented patch is called VITILLIGO...,
cause is unknown...but it is genetic predisposition....
b) Hypopigmented may be due to ....fungal, worm infestation..,
vitamin deficiency..,etc..,
So first evaluate the patch ...,
2) Depigmented patch is not curable..,
it can only controllable..,
Hypopigmented patches are curable..,
3) Depigment patches are very slowly spreading....if treatment starts.,
it will stop..,
So consult good
dermatologist and he can give correct direction..thanQ
