I wash my hair with nothing other than best quality natural water. No shampoo, no conditioner. Just brushing the natural oils in my length and occasionally giving my hair a treat with a little bit coconut oil. Can you tell? I certainly couldn't from the way it looks and from the way that it smells neither. Your scalp adapts to taking care of itself again, because the use of shampoo is in fact what is pushing it to be oily and smelly, because it brings your scalp microbiom out of balance.
The key for success is the quality of water that you wash your hair with. I prefer spring water (if you don't have one near you, you can buy yourself a bottle). Rainwater works really good as well. In case your tap water is as shitty as the one where I used to live.
Keep in mind, It took me a long time to get here, figure it all out. But it was worth it 💁♥️#naturalhair #wateronly #nopoo
