A dry shampoo is a very good idea for those who lacks time. I think that every girl was sometimes in a situation when she doesn’t have time but should look cool, so using a dry shampoo is right what you need. To make it at home you’ll need cocoa powder, corn starch, essential oil. If you have dark hair: use 2 parts cocoa powder, 1 part cornstarch. If you have light/blonde hair, you can omit the cocoa powder, and just use the cornstarch and a few drops of your favorite essential oil! Mix all ingredients and combine well. Store in a small container and apply with a makeup brush or sprinkle through hair and comb.
