Kerastase Specifique Densitive GL

Kérastase Specifique Densitive GL · $40

So this is a little different than my normal product posts buuuuut sometimes different is good. 

I purchased this little bottle on a whim (but also with a recommendation) after getting a haircut last week. When my hair is in its natural state aka curly and big enough to double as a lions mane, I have no issue with volume and body at all. When I straighten my hair which is most of the time, my hair tends to lay flat and not really do much of anything. When I went in for my cut and style, I told the stylist what products I use, told her what I was looking to achieve when styling my hair, and she recommended this. 

Kérastase Specifique Densitive GL is a thickening spray which is supposed to soothe the scalp and stimulate micro-circulation while also adding texture and volume to thin/lifeless hair. You spray it on — roots to ends — and blow-dry for the finished effect. What you're left with is natural looking volume and body. I normally spray this roots to mid-shaft (leaving out my ends) and massage into my scalp before blow-drying. I feel as though my ends don't really need it/there isn't really a purpose for spraying them because I want most of my body at the top and middle! You can also spray this on dry hair and blow-dry for a nice and even more voluminous effect. Overall I'm really happy with this so far and it's definitely helped me use less product in the long run while doing my hair. I really want to check out the Kérastase Résistance shampoo and conditioner which is supposed to be amazing for weakened and fine hair. 

Have you tried any Kérastase products? Which are your favorites?
