Key Ingredients





How to Use

Gently apply 1 or 2 pumps on dry or wet hair from lengths to ends. Leave-in. Follow with Thermique Régénérant.

Thermique Régénérant is my new must-have for heat protection. I always put it on my hair first before any other styling products, like a coat of primer before the paint. If I don’t blow dry my hair smooth, I can use it to diffuse my curls, and all day they’re frizz free and softly refined. For the most luxurious fragrance and lightweight oil that fully absorbs into your hair, I love the new Huile de Parfum. It’s the quintessential “treat yourself” product and can be used all day on dry hair to smooth flyaways and add a gorgeous rose and woodsy scent. The beautiful bottle is a perfect designer accessory for your vanity, so don’t hide it in your bathroom cabinet!
