A dermatologist at Wexler Dermatology, Francesca spoke of the importance of exfoliating your scalp every now and again, which can be easily done by lathering your shampoo with sugar.
"Adding a tablespoon of sugar to a dollop of shampoo will gently exfoliate the scalp and easily dissolve and rinse out without leaving any residue on hair."The use of sugar will get rid of all those icky dead skin cells, dandruff and general grease - as well as excess shampoo.
