I made some DIY dry shampoo!
Which totally worked!
The only thing I would suggest is to NOT... I repeat... DO NOT put it in an empty garlic shaker... my hair might not be greasy anymore but it sure smells like garlic! Hahaha
1 teaspoon Bentonite clay - I get mine from pure nature
5 teaspoons Cornflour (cornstarch for the Americans)
Place into a shaker or just in a jar with a spoon and place on the scalp of your hair in small amounts and rub in.
