If you have coloured or damaged hair, it’s best to avoid washing it as much as possible. For me, I’ve managed to avoid washing my hair for up to two weeks (yeah, you read that right). If odour is your concern, there are also ways to freshen it up without the water or soap. And don’t worry, all of these tips are cost friendly. Like you, I am also the average income consumer who doesn’t have a lot to dish on super expensive products or hair treatments.
