The two things that you can use to remove build up from your hair are :
Baking soda and Apple cider vinegar.
I think the best way to use them it would be like I have described it in "the no poo method" post.
I don't recommend using only baking soda if your hair is dry. BS is slightly alkaline and it will open up your cuticle. In this way it will make your hair a mess and even drier.
As for the ACV you can use it in two other ways.
- Fill with lukewarm water a water bottle,add 4 tablespoons of acv and use it after shampoo.Just like you would do with a conditioner.
- Fill the sink with lukewarm water(make sure the sink is very clean,without any soap residue) and add 3/4 cup acv. Soak your hair for 4-5 min, then squeeze and rinse. This is what I did about 3 hours ago and my hair feels so soft now. It doesn't smell at all even if it's still damp. I didn't shampoo previously, but I'm washing it after a few hours. When to use it,before or after shampoo, is your choice. Try and see what works best for you. Acv will also help with removing mineral build up in your hair.
And this is it.So easy!!!
I hope I haven't forgotten anything. If you have any questions ask me in the comments :)
