Marcia Texeira changed the formula of their shampoo in a very deceptive way. (See my letter to them below.) Thus I urge anyone who has had a BKT to use a shampoo that doesn’t have ANY sodium molecules in it. (I switched to Rejuvenol’s Keratin After Treatment Shampoo.)
I am a doctor who has had her hair straightened with your BKT Treatment and who used your “Marcia Teixeira Keratin Shampoo for Color Treated Hair “ before you changed the ingredients. The original product had no sodium--any form of which damages the keratin in hair; it contained Lauryl Sulfate and Ammonium Laureth Sulfate. The current version has sodium in it (Disodium Laureth Sulfosuccinate), but unsuspecting users would never know because (1) the ingredients are printed in a font that is half the size of the one on the original bottle and (2) you advertise the product as being “sodium chloride-free.” As any chemist knows, although the sodium molecules in Disodium Laureth Sulfosuccinate are less corrosive than the ones in sodium chloride, they still chemically remove keratin from the hair’s surface. Yet people who don’t know this will see your advertisement of “sodium chloride-free” and think that the shampoo will keep or even add keratin to their hair rather than strip it out.
Even worse is the fact that the Disodium Laureth Sulfosuccinate is the second ingredient after water on the product list. This means that the new formulation of your shampoo has more Disodium Laureth Sulfosuccinate in it than any other ingredient except water!
Not only is this misleading and deceptive, but it seems fraudulent: You have created a brilliant way to hook women into needing to have your BKT treatment done more often, because after they have it done, they use your shampoo which strips the product out of their hair, thereby speeding up the time in which they need to get the treatment redone.
Thus, I want a response about why you added sodium molecules to your shampoo and why you think that using this new formulation won’t strip out the keratin that your treatment puts in.
