You may be wondering if your hair can benefit from a protein treatment if you are new to using it. Generally, color-treated, relaxed, heat-styled, and natural hair all need protein. Rice water for hair growth is believed to make hair shinier and stronger, as well as help keep tangles at bay, so it can be used as a treatment for fine, dull hair. Proteins in rice water hair growth may benefit those with dry, brittle, curly hair because they help improve hair condition and make it bouncy. It may also benefit those who want their hair to shine and their cuticles to be stronger. All hair types can benefit from rice water hair growth.
