Kerastase Densifique Densimorphose Densifying Treatment Mousse 5.1 oz

[This review was collected as part of a promotion.] I am a surgeon over 65. My hair is thin, fine and fairly straight hair. I have a few curls at my side burns! My wear my hair short and it is slowly showing the gray, so I have it professionally colored to my natural medium to dark brown. This is a great product for adding density and texture my hair. I simply work it through my towel-dried hair, fluff with my fingers, straighten my side burns with it; and I am out the door!

I have mid length fine hair and this mousse is perfect for days when I want my blow dry to really last. I really love this product. That said, if I use it on days when I do a hard work out (sweat) it actually makes my post workout hair look worse than if I had used another styling product. Whatever wonderful thing in it that makes my blow dry last when I am not working out gets very heavy and looks really bad when it gets sweaty so perhaps hold off on using it when you know you are going to get your hair exposed to moisture somehow? For example, if it's a rainy day....? Otherwise, with that very specific qualifier, this mousse is now part of my must haves.
