✱ 1 – You Can End Up With Acne
You already know that bacteria will breed on the pillow if your hair is wet. When that bacteria goes on your skin, you will end up with acne as it fills your pores. Therefore, that in itself is a reason to not sleep with wet hair.
Again, if you want to take a shower before going to bed, be sure to blowdry your hair before going under the covers or wear a shower cap.
