Is it normal to not wash your hair for a whole week at a time?
I don't wash my hair for sometimes a week at a time. It does't get greasy until the end and even then it doesn't look bad.
At first it was to do with laziness (I still wash my body) but my hair is healthier looking now. My hair dresser even said it's a lot nicer. She said we need the natural oils in our hair for it to be healthy (washing your hair every day will actually dry it out and make it greasier faster)
I've heard not washing your hair for a couple of months results in very nice hair once it's got passed being greasy... It makes sense because naturally, we never would have washed our hair.
