False. Your hair doesn’t build up a tolerance to any certain shampoos or conditioners. This myth derived from the fact that your body builds up a tolerance to certain substances, like coffee or alcohol for example. While this may be true, hair products don’t act in the same way. If something worked when you first used it, it should always produce the same results. The disconnect here is that many synthetic chemical products can appear to work at the beginning by coating your hair with silicone, making it shiny. While they may give you that instant shine that you yearn for, this perfect hair day won’t last. Over time these products will eventually build up on your hair and cause breakage.
All in all, choose a high quality shampoo and conditioner and you won’t have to worry about its longevity.
