It depends on their hair. If you have super curly hair you should wash it every other day... maybe every 3 days. If you have greasy hair then wash it everyday. If you have straight hair just wash it everyday. Mostly every girl washes her hair everyday.
I am mixed black and white and need moisture in my hair. I dont wash it everyday because it is cheaper and better for your hair to not wash out the oils. I also dont like my hair greasy because I notice more acne I am 33 and have flawless skin. My advice wash your hair once a week use pink oil moisturizer and a silk hair cap at night and a leave in conditioner.
Women should wash their hair at least every two days. But I wash my hair everyday.
They can wash their hair, there is no reason that they cannot.
Yes, you should wash your hair if you are sweaty. Washing your hair is on an "as needed" basis. If your hair is greasy or sweaty you need to wash it.
Although I wash my hair everyday, it is said to wash your hair every other day in order to keep the natural oils and not dry out your hair.
That's different from person to person? xD Most actually wash their hair everyday because of how much hairspray and stuff is used, but people with f. blue, pink, green hair and all colors, normally doesn't wash their hair that often because it washes the color out. And the more greasy the hair is, the easier it is to style it.
Twice everyday
It's impossible to completely remove it, but if you use clarifying shampoo and wash your hair everyday, it will wash out faster.
Yes. If you wash your hair with shampoo everyday it takes away your natural oils and if you don't have your natural oils your hair will get greecy
Yes. Your hair could start being a haven for lice.
