How hard are you on your hair? Just brushing itself can hassle strands so I’m glad I picked up KERASTASE Ciment Thermique Heat-Activated Reconstructor Milk for Weakened Hair ($36/4.8oz @ amazon.com). I mean, I color, flat iron, tease, blow dry and lately use a curling iron on my hair weekly. So you can imagine that my hair needs some sweet lovin’ sometimes and I didn’t really know how well this one would boost the overall look and feel of it. It’s heat-activated and contains the patented ingredient Vita-Ciment that goes to the core of the strand to repair and Vita-Topseal that replicates the protective layer of the hair fibre. Think of this as a hair mask that works while you use the heat of a blow dryer or styling iron! And they claim that it’s results lasts up to 5 shampoos. Big Recommendation.
