Ans: You should choose the relaxer strength according to the texture of your hair. The rule of thumb here is, for fine hair, choosing a mild strength relaxer is best. For regular hair, a regular strength relaxer would work better. If you have coarse hair, then using a super strength relaxer should fetch you the desired results. Remember, just because you have very thick hair, there is no need to think that you will need super strength. It depends on the hair strands and not on the thickness. It is best to perform a strand test before applying a product.
