Hair
You might be used to shampooing every time you get in the shower, but your hair might not like it as much as you think. When you let your hair get a bit of natural oil, it looks shinier and less dry. Washing it every day is definitely too much.
You should give your scalp the chance to balance out. If you try this and you don’t see an immediate improvement, just give it a bit of time. After all, shampoos are designed to clean the scalp and remove any excess oil. But if you overdo it, it might only damage your hair.
