Have you ever wondered why your friends hair grows so much faster than yours? You've tried every product and every hair regiment but nothing seems to work. Hair textures and products used on these textures have a tremendous amount of compatibility. When making choices for hair products you need to know the amount of moisture or lack of moisture on your hair . There is a such thing as over saturation so please read the manufacture label and follow the instructions for application. Some conditioners are heavier than others so be careful to use the right consistency on your hair type. Shampoo comes in many formulations and don't get stuck on my favorite type. Its good to switch products because your hair can become bored with the same stuff you re use to. You should always use a clarifying shampoo to clear any buildup on hair. Moisturizing shampoo is used on that hair that's really curly and needs some taming. Your specialty shampoo would be a sulfur base product for troubled scalp. The shampoo that has the word "pre" on it would be used to prepare the hair for a process. This will allow the PH level of the hair to help maintain the right level during a preparation process. Your Neutralizing shampoo is just that, and will only bring the PH level of your hair back to its correct level after a chemical process. Make sure you trim your ends and be knowledgeable of the products you use. If you don't know whats going on your hair, just ask.
