I need some hair help/advice. My hair is thick, wavy/frizzy, slippery, and dry, and I get a really itchy scalp. I like to keep it's natural wave so I rarely use heat or products on it. I'm sure this is because I'm using cheap shampoo and conditioner. I was having a problem with frizzy all-over and oily roots, so I tried the "no poo" method. I loved it because it got rid of the frizz and oily-ness and made my waves turn into beautiful ringlets. The only problem was it made my itchy scalp even itchier! I think the baking soda was too harsh or something. Any tips for shampoo or conditioner that can help me with all of these problems? Or is there a different moisturizing "no poo" method I can try?
