As a stylist I have been told to tell my clients to use “sulfate-free” shampoo if they have color-treated(or curly) hair. However, I read in your book that you’ve studied the performance of sulfate-free vs shampoos containing sulfates and didn’t see a difference in hair color fading. Is there anything out there that preserves freshly colored hair?! Is there any benefit of using a sulfate-free shampoo as far as frizz goes?! I stumbled upon this company, purely perfect, and that say sulfates damage the hair?!
Thanks!!Q: I read in your book that you’ve studied the performance of sulfate-free vs shampoos containing sulfates and didn’t see a difference in hair color fading.A: True. While there is data that shows sulfates can be irritating to skin (because they interact with skin protein and don’t rinse well) there is no data showing they cause color loss. In our lab testing they caused no more color loss than other types of shampoo.Q: Is there anything out there that preserves freshly colored hair?!A: We’ve seen data from chemical suppliers showing that a variety of ingredients can reduce color fading. The only one product we have personal experience with is the Tresemme ColorThrive S/C (not Color Revitalize.) It may be discontinued, I’m not sure. If you can’t find the Tresemme product I’d look at the L’Oreal Color Radiance line since their color technology is quite good.Q: Is there any benefit of using a sulfate-free shampoo as far as frizz goes?A: Not necessarily. The anti-frizz effect of a shampoo is determined more by the conditioning agents than the surfactant.Q: I stumbled upon this company, purely perfect, and that say sulfates damage the hair?!
A: Of course they say that – they sell sulfate-free shampoo!KAL06 you may want to reccomend your clients use a pre-oiling method prior to shampooing. Put some coconut oil in the hair, let it absorb. Some will still stay unabsorbed where the hair is less porous but it will help buffer more damaged parts of the hair (usually the ends) from shampoo dryness, whether the shampoo is sulfate free or not. This is one reccomendation I’ve been told works for a lot of people with thin or oily hair who feel that conditioning shampoos weigh down their hair, yet they still want the color protection. Might be an option…
Sulfates don’t rinse as well as some other surfactants because they can bind to keratin protein. Hence the potential for irritation.
I’m not sure which specific factors determine its “stickiness” but this is really only a problem if you find sulfates irritating. If they don’t irritate you, then you can use sulfates no problem. If they do irritate you, switch to a sulfate free formula.
Oh okay. They are the only thing that makes me look non greasy and they don’t bother me. But my mom was shaving flakes even with regular dandruff shampoo use so I convinced her to buy sulfate free shampoo and her flakes went away. She has rosacea though and people with it seem to be really sensitive.
