In general yes, any permanent hair coloring is harmful to our hair because it requires some strong chemicals to open up the cuticle of the hair to slip the color underneath. Then, if you add discoloration (aka bleaching) before adding up the color, it's even more harmful because there you will rip your hair off some of its components to make it lighter. BUT at Hairqare, we believe that you can have the best out of both worlds. You can great hair and dye it... AS LONG AS you grow out the healthiest strand possible and apply the right care practices. So if you maximize the health of your hair, it will be able to stay healthy enough even with some coloring. How to maximise your hair health and potential in the long run?
