Tiffany wants to know…Could you please do a chemical comparison between the new Kerastase and Elseve shampoo and conditioner? They are both packaged very similarly- pink bottles- claiming no silicone and krystal shine. I’m not of the exact name in the USA since I am in France, but I spend 35 euros on the Kerastase shampoo and 3 euros on the Elseve! Quite the price difference! Please tell me there is something worth the 10xs time hike!
The Right Brain responds:
Tiffany is referring to Kerastase “Cristalliste” and Elvive “Nutri-Gloss” both of which are made by L’Oreal. While the Elvive product has been around for a while, Cristalliste is newer and makes several breakthrough and compelling claims including:*
Rebalances the hair fiber.
Roots are left pure and weightless.
Ends are smooth and polished.
Hair is perfectly clean, luminous and weightless.
*I was being sarcastic. These kinds of claims have been made by other hair care products for years.
A comparison of the Cristalliste Bain Cristal (Fine Hair) shampoo Ingredients and the Elvive Nutri-gloss shampoo shows that both have water as the first ingredient as is expected. As the second ingredient, both have a “laureth sulfate.” Kerastase has ammonium while Elvive uses sodium Both ingredients work the same way so it doesn’t really matter. As the third ingredient and fourth ingredients are salt and betaine. These are essentially foam boosters and thickeners. The the formulas are the same so far. After that we see that Kerastate uses a guar conditioning ingredient while Elvive uses a combination of guar and silicone.
What does all this mean? Both shampoos have the same cleansing “backbone” although their conditioning systems are somewhat different. You may prefer one over the other but there’s NOTHING in the Kerastase formula that would merit a ten-fold increase in price!
Now onto the conditioners: In this case both products are based on a mixture of Cetyl Alcohol, PEG-180, and Behentrimonium Chloride. The Cristalliste version contains 2 additional conditioners that may or may not significantly alter the feel of the product but again, there’s no advanced technology that would drive the price up.
Both Cristalliste and Elvive shampoos and conditioners are well formulated and you should buy the one that you like the best and that you can afford. But if you’re trying to save a few dollars you’d be much better off with the Elvive product.
