To keep my color fresh after a visit at Neil George Salon I almost exclusively use Kerastase hair products (sometimes I alternate with Davines). I try not to shampoo too often but when I do I switch off between the Bain Chroma Riche which is for dry, highlighted hair and Bain Satin #2 or #3 for moisture.
For conditioner I use Lait Vital for everyday and then use the Chroma Riche hair mask about once a week to keep my hair in tip top shape. I also really adore Davine's Love conditioner because of its yummy grapefruit scent.
Before every blow-dry I put the Ciment Thermique and Oleo Relax throughout the ends of my hair for heat styling protection and shine. I'm also hearing great things about a new product that used to only be available overseas called Noctogenist which comes in a serum or cream and is used as an overnight repair product.
Kerastase can be purchased at some of my favorite salons: Neil George Salon in Beverly Hills, Osgood O'Neil Salon in Dallas and Butterfly Salon in New York.
