In the quest for down-to-there hair, there’s nothing we won’t try. Weekly deep conditioning treatments? Check. Hair vitamins? We’re on our third bottle. Scalp massages? 10 minutes a day. As dedicated as we are in our pursuit of princess-length locks, there’s at least one thing we’re not willing to try: giving up heat styling.

Many people have credited kicking heat styling to the curb with helping them restore their luscious, long locks, but giving up heat styling your dark brown hair may be asking a bit too much if you’re more committed to you flat iron than you are to your relationship. What if we told you there was a way you could continue to heat style and grow the long hair you’ve always dreamed of? Kérastase heard our cries and came up with the perfect solution: Kérastase Résistance Extentioniste Thermique Blow Dry Primer.

Is heat styling getting in the way of your long hair fantasies? Continue reading to learn how Kérastase Résistance Extentioniste Thermique Blow Dry Primer is going to change your hair forever.


Why Use Kérastase Résistance Extentioniste Thermique Blow Dry Primer

When attempting to achieve down-to-there length, many people search for ways to make their hair grow faster. Unfortunately, there is no way to make your hair grow faster; everyone’s hair growth cycle is determined by their DNA and there is no way to change it. The good news is that your hair is always growing. So, the question is not whether you can make your hair grow faster, but how to hold on to the length you already have.

While many things can lead to hair breakage (including fragile strands, rough styling, and unruly snarls), heat styling is one of the worst culprits. When used at temperatures too hot for your particular hair type, hot tools can zap the moisture from your hair and leave your strands dry, brittle, and broken—effectively putting an end to all of your long hair dreams.

If you’re an avid heat styler, chances are good you’re not new to heat protectant products (at least, you shouldn’t be!). While heat protectants are good at helping to shield your hair from the damage caused by high heat, not many of them are formulated to tackle your other hair woes. Kérastase Résistance Extentioniste Thermique Blow Dry Primer is different than products you’ve tried in the past because it’s formulated with creatine R and taurine to protect hair up to 450 degrees Fahrenheit and reinforce and seal lengths and ends for up to 90 percent less breakage. The equation is simple: less breakage equals longer hair!


How To Use Kérastase Résistance Extentioniste Thermique Blow Dry Primer

If it sounds like the Kérastase Résistance Extentioniste Thermique Blow Dry Primer is right for you, you’re in luck. For best results, we recommending picking up the rest of the products from the Extentioniste range, including the Résistance Bain Extentioniste Shampoo and Résistance Fondant Extentioniste Conditioner.
