The use of good shampoos for chemically treated hair is one of the best ways to keep hair healthy. Harsh hair chemicals such as color and perm are very high on the pH scale which means that they are alkaline. This is why commercials always make a point to advertise that their shampoo is acid balanced. The pH scale goes from 0-14, which means 7 is neutral; below 7 is acidic and above 7 is alkaline. Many hair chemicals are at 10 or higher on the pH scale. Now, you know why you need an acid balanced shampoo. I learned all of this way back in 1983 when I went to cosmetology school.
Yes, I am still a licensed cosmetologist working in a salon and do quite a bit of hair coloring and perming on a weekly basis; mostly women as well as a few men and have used these brands of good shampoos for chemically treated hair. This to let you know that I speak from experience and will not recommend any hair products that I have not used on myself or others and that these hair care products are indeed some of the best on the market, as I have used them for many years.
I have favorite color treated shampoos that I alternate often and most of them are salon shampoos with the exception of one and that one is Herbal Essences Color Me Happy. Color Me Happy is an excellent drugstore shampoo for color treated hair. My salon favorites include: Vavoom Bust Out Body by Matrix, Color Protect by Paul Mitchell, Redken Color Extend, Biolage Color Care, Lavender Color Protect by Back to Basics, Tigi Bedhead Superstar Sulfate Free and Kenra Color Maintenance. All color treated shampoos also work well for permed hair; it’s more about the acid balance than anything else.
Keep in mind that using good shampoos for chemically treated hair isn’t the only thing you can do to keep hair healthy. How often to shampoo is a question I am asked all the time and the answer is always about twice a week. Shampooing too much is hard on chemically treated hair, since it is more fragile than hair that is chemical free. Be careful when it comes to chlorine and hard water mineral deposits, they’re bad news and can destroy hair in no time.
Lastly, do not shampoo hair for 48 hours or longer after a chemical service. When you finally do shampoo hair use tepid to cool water, hot water is harmful for hair of any texture.
