TOPPIK Is an hair concealer:
as of now in India, it is not available in any of the retail shops,
there is just one distributer in delhi and the prices he quotes are high compared to ebay.
One more thing is the HT clinics generally stock the concealers like toppik.
Also available on e-bay.
Another one is nanogen.
The basic requirement for a concealer to work is that the scalp
should have some hair to hold it. no one can detect it easily.
Hope you have got ans.
