well are there some days where you just don't use it? I hear its better for the scalp if you go every other day without shampoo. my hair is really short so I don't even bother with it. I just use shower gel every where but my hair obviously, and I end up smelling really nice.
so for long hair it seems best to just use conditioner. I used to shampoo my hair everyday
The ingredients in shampoo strip your hair of almost every thing, even hair coloring if you have it, so imagine the amount of natural oils that keep your hair moisturized and protected being stripped away by constant shampooing, shampoo about every 2 days apart and you can condition as often as you want, conditioner has no harmful effects.
I went for close to month without it once, just to see how it worked. My hair was good, but I have nasty ass dandruff so my scalp just had a layer of dead gnarly ass skin on it. Though I don't shower every day anyways, so I guess I'm good.
I used to use shampoo everyday but I heard it drys out the scalp and makes hair dry because your hair has oils and nutrients it needs and washing it to much with shampoo strips it from these oils and nutrients
I only use shampoo twice a week now unless I feel like my head needs a good scrubbing from working outside or being outside on general
