Redken Extreme Anti-Snap Leave-in Treatment - reviewed and rejected

Is a Solution for:
Dry or Brittle Hair
September 3, 2009 Reviewed by Marta 6 Comments
I was recently asked by someone with hair that tends to break and split what I thought of Redken's Extreme Anti-Snap Leave-in Treatment ($17.99). Before even looking at it, I was tempted to suggest that she just try emu oil, which has a proven track record for strengthening hair as well as waking up sleeping hair follicles. Having looked closely at Redken Extreme, I would now say that it would be probably safer to swim across the Hudson River than leave this product on your head. The Cosmetic Database seems to agree with, giving Redken Extreme the dubious honor of a nine out of ten hazard rating.

One of the culprits could be Arginine HCl. Arginine is an amino acid, but arginine hydrochloride is listed in the Cosmetic Database as a neurotoxin (although I couldn't find the studies cited) and, according to the Material Safety Data Sheet, is hazardous if in contact with the skin (this is at a pure concentration). Polyacrylamide is a polymer that is formed from units of acrylamide, a known neurotoxin. However, Polyacrylamide itself is not considered to be toxic, but is a controversial ingredient because of its potential ability to secrete acrylamide, according to Wikipedia. Although allowed by the FDA, concentrations used in cosmetics are limited.

There are several laureths in this product. The number (eg laureth-230 refers to the level of viscocity. However, there is some research that suggests that the higher the number, the more likely it is to cause irritation. Oleth-10 can be an irritant, increase the penetration of other products and be contaminated with carcinogens. Then there is a couple of parabens and  phenoxyethanol at number three in the ingredients list.

The few good things - wheat amino acids, taurine (an antioxidant) and soy protein - don't really stand a chance.


Water (aqua), Cyclopentasiloxane, Phenoxyethanol, Polyacrylamide, Dimethiconol, C13-14 Isoparaffin, Laureth 23, Laureth 4, Laureth 7, Methylparaben, Disodium EDTA, Ethylparaben, PPG-5-Ceteth-20, Hydrolyzed Soy Protein, Wheat Amino Acids, Arginine HCl, Taurine, Oleth 10, Disodium Cocoamphodipropionate, Lecithin, Hydroxypropyl Trimonium Hydrolyzed Wheat Protein, Phosphoric Acid, 2 Oleamido 1, 3 Octadecanediol, Trehalose.

    My niece and I purchased redken extreme anti-snap leave in conditioner and after using it 2 times we both had a terrible itchy break out on our scalp. Something toxic in this product.

    Someone posted a question about the controversy they heard over this product.. that i am now hearing of for the first time. I modeled for Redken about 12 yrs ago and i remember I couldn't stand to use any of their products because I knew how damaging they were and just how much press we had for the bad ingredients put into them. I never knew until now just what those actually were. A friend bought me a complementary leave-in conditioner as a "gag" gift and i used it a week ago and after 15 mins when i went to rinse it out, I seriously had PASTE LIKE CHUNKS stuck in my hair the next day. I had to tug and tear at to remove these. If some don't know what Polymer is:A mixture of Clay and Glue compounds. Hows that for some DEEP conditioning? Thank You .. this was extremely informative!

    Thank you!
    I had an allergic reaction shortly after using these Redken anti-snap products. My skin itched and turned pink everywhere. It took an antihistamine and a steroid to get it to stop. I had a hunch it was the switch in hair care products, and now I know.

    Thank you for this!

    I have been using Anti-Snap for 5 days now (3 washes/applications) and I have had CONSTANT hives around my neck, down my back, and across my chest. I have really long layered hair with moderate breakage, and my roommate had suggested AS to help repair & fortify. She has eczema, and I have minor allergies to things like cats, horses, and hay, so I figured I wouldn't have a problem- I've never had any problems with any beauty product before.
    Yes, I noticed my hair isn't as frizzy, or as fluffy at the ends; Yes, it's looking healthy and glorious. But the hives on my skin are UNBEARABLE!
    So thank you for explaining why my skin hates this product.

    Today is my first time on this website and I have found it very informative but I had to leave a comment on one of your reviews. I have used Redken Extreme and I Love It! It
    conditions my hair on a deeper level when I need to do something different then a quickie rinse out conditioner or a leave in. In fact sometimes I will put it on and leave it over night and rinse the next day and my hair looks so healthy and soft. It smells good to!
