KÉRASTASE Genesis Blow Dry Primer, Heat Protectant for Weak or Damaged Hair, Anti-Breakage, Detangles and Hydrates without Frizz, Sulfate Free and Defense Thermique, 5.1 Fl Oz

I love this product. It smells so good on my hair and it really goes a long way to protect your hair from the heating impacts of styling tools and blow dryers. This brand is high-end quality and you don’t need to use a lot of the product to get the full advantage so you can use it sparingly. Did I mention it smells so good?

If you’re over 50 and suddenly find your hair is rebelling against you, you need this. Somewhere around 55 my hair began to dry out, became dull and brittle. My stylist used this on me and it is like a miracle. It softens, smoothed and shines with just a few sprays when wet. This is one of those products you find and use for life.

The Kerastase blow dry primer has worked wonders for my processed hair (monthly highlights). After a month of use my hair Is noticeably smoother and less brittle, especially at the ends. Product seems to last about 2 months for me - I wash my hair about every other day. Originally recommended by my stylist - Amazon pricing slightly better and arrives quickly. Also I love the smell of this product!

This product applied very easily and was soft on my hair. Great value for the money.

This blow dry primer leaves my hair feeling soft, smooth, and way less frizzy. It also does a great job protecting from heat and detangling. But the spray nozzle isn’t great, it’s hard to control and sometimes sprays unevenly, which can be annoying.

After watching Bravo and hearing about Kerestase hair treatment for my humid hair I splurged on this hair protectant and was surprised to find how well it works when blow drying to eliminate frizzy hair.

My salon used to use this product so I bought it to use at home, but I don't think it protects against heat as well as some other high-end competitors. I prefer the Oribe equivalent even though the price is not any less expensive.

Great product to smooth your hair
