Charlotte Comments: I’d love to believe that those curling shampoos will really shape my thick hair. What do the Brain’s Believe?
The Right Brain Responds:
Well, Charlotte, this is an easy one. Curling shampoos do NOT make your hair curly. In fact, if you read the labels carefully, some of them don’t even SAY they’ll make your hair curly! Let’s take a look, shall we?
What do curling shampoos claim?
Even the most flagrant offender of the truth, Wash n’ Curl shampoo, only IMPLIES that it will make your hair curly just from shampooing. Read the label carefully - it says it provides “the most beautiful curls with body, bounce and resilience after styling.” Well, duh! If the shampoo only makes your hair curly AFTER you style it, it’s not really doing much for you is it?
What else does Wash n’ Curl say? “Your hair will be extremely curl responsive…Even dry, damaged, color treated hair will have the staying power of thick curly hair… Its special Curl Enhancers infuse hair with the Holding Power of naturally curly hair.”
The chemistry of curling shampoo
The only piece of truth in this claim is that the shampoo does contain something that could be called a “curl enhancer.” Looking at the ingredient list we see that it does contains a polymer (Acrylates/C10-30 Alkyl Acrylate Crosspolymer), that COULD provide some styling benefits. But that would only work if it wasn’t rinsed out! Remember, just because a product contains an ingredient that does something, it doesn’t mean that it does something in that product!
The rest of the claims are pretty much made up, as far as we can tell. There is no shampoo technology that will measurably improve the holding power of your hair.
What about other products, you ask? Well here’s two more:
KMS Curl Up Shampoo and Marc Anthony Strictly Curls. Neither of these shampoos make strong curling claims. KMS only promises to be your “curl’s best friend, ” to ” start your style in the shower,” and to “boost boisterous curls while adding moisture and shine.”
Marc, on the other hand, offers to protect color; repair dry, frizzy areas, and repel humidity to define shiny, soft, curls. (”Define” curls is not really a very emphatic claim.) Aside from a little polyquaternium (a conditioning ingredient) neither of these products have any curling technology either.
We could go on and on, but you get the picture. These shampoos don’t have anything in them to make your hair curly. They don’t even really do anything to prepare your hair for styling, other than getting it clean. If you want to see more, click the carousel below.
The Beauty Brains Bottom Line:
If you really want curly hair, go buy some mousse. Or, God forbid, get a perm!

It amazes me how good the cosmetic industry is at making what appear to be pretty blatant implications that, when you squint and look closer, are actually not at all claims of any efficacy whatsoever.
I’ve been in marketing for years and it still astounds me.

Even more odd that this, are the new shampoos for layered hair. WTF?
Michelle B Says:
I’ve actually found that curling shampoo is great for making my hair straight! The bumble & bumble stuff weighs my hair down so much that it looks better after it’s flat ironed!
