If your hair is drying out all the time, use conditioner instead of shampoo to clean your hair.
The oils in it will loosen and lift dirt and old surface oils and rinse away.
I use shampoo maybe once or twice a month, not much.
I do clean my hair about every other day or so using conditioner.
It works good, no dryness, no split ends, less hair pulled out when brushing.
This also works well if your skin is dry, use a good moisturizer to clean the dirt and excess surface oils.
Oils in moisturizers will dissolve the oils much like soap does, without stripping away the oils under the surface.
If you look at the main ingredient in most body wash and shampoo, its laurel sulfate, the main ingredient in garage floor cleaner.
It's also small enough molecules to penetrate your skin and get into your system.
Ammonium sulfate is larger and doesn't do this. It's used in the better body washes and shampoos, instead.
Neither of these are particularly good for your skin or hair, they are there to strip away the oils, so that you have to use conditioner and moisturizers.
Why strip the under surface oils away when you can more gently lift the dirt and excess surface oils away and retain the natural oils you're meant to have?
It really does work and cleans just as well.
My hair is past the middle of my back and hasn't had a split end since I started doing this a couple years ago.
Not even my old brittle grey hairs have them, they are as smooth as can be.
Try it for a month, I did and I won't go back to using garage floor cleaner on my skin or hair again...
