I have used hair relaxer three days ago, and I have still have not washed my hair. I have used Mizani relaxer. Even I have been working out little so that I had a little sweating. I have also used a bit of Redken hair serum on my hair. Is it fine to wash it now? I have a biracial hair, if that makes any difference. How long after using a hair relaxer can I wash my hair? How often should I use shampoo or conditioner on it? I would really appreciate your feedback. Please advice. Thanks.
