Rated 5 out of 5 by from Great Mousse My hairdresser introduced me to this product. I absolutely love the way it makes my hair feel. It is very light and silky in my hair but also does a great job to maintain the style of my hair.

Rated 1 out of 5 by from None I bought this hoping that it would be as good as K Mousse bouffant. It isn’t. I have found that Nexxus has a mousse that actually works better.

Rated 4 out of 5 by from A mouse that works...... I really appreciate a mousse that helps my hair hold style and gives body. This mousse works well. You don't need to use a lot so it lasts. My only complaint is that toward the end of the product, the applicator stopped working and the mousse was just liquid. That was disappointing. I have ordered again and hope I can use every last drop m

Rated 5 out of 5 by from Amazing! I am a 22 year old guy with fine hair that has started to thin out over the last few years. The salon I go to carries Kerastase products and when I complained about my hair, my stylist used this on me. Cannot live without this product now! It really does work at giving a more dense feel to my hair. In certain light when my hair was freshly washed you could see my scalp through the hair. Not anymore with this styling product. I plan to give the shampoo and conditioner a try soon. Yes, its an investment but out of all the products they have out there that claim to give you more hair, this one actually does it. It also does not dry out your hair or make it feel crunchy like some of the volumizing mousses do. Kerastase does market more to women, but I have started using them a few years ago and have really noticed a difference.

Rated 5 out of 5 by from Cannot survive without it I have been using this for over a year and absolutely love the product. This is NOT a styling product but gives your hair extra volume. I have been using Hair, Skin & Nails and an extra 5000 mcg of Biotin to get my extremely thinning hair to grow back. It took a good 6 months to notice the difference but together with the Mousse, Bain Densite and Fondant Densite I feel like a new person. My husband actually remarked this weekend "wow, your hair is so thick". It does not happen overnight but with perseverance these products really made a difference to me.

Rated 5 out of 5 by from Works great with fine hair! I originally bought this at a salon in Tucson AZ and was a bit skeptical. I decided to use it every time I washed my hair and it has made a huge difference. I ordered 2 to keep on hand bc it helps my hair so much!

Rated 5 out of 5 by from Absolutely Perfect! I've been using Densimorphose Mousse for a couple of weeks. My hair is very fine and the slightest wind or dampness makes the ends frizz or lose the styling. This mousse stops that completely without hairspray and yet doesn't weight my hair down or make it feel sticky. Love it!

Rated 5 out of 5 by from One and Only Hair Mousse I had been shopping around for a great volumizing and thickening mousse for my mother who's hair has thinned. I had tried everything and nothing was really impressive. Lo and behold, Densimorphose. My mother who is a tough customer, loved it. It is truly a lifesaver and I actually use it myself. My hair looks good smells good and it doesn't feel sticky like other mousses. I love it too because often, I don't feel like using multiple products and this mousse does it for us. I always believe that our hair is our crown and Densimorphose is giving me great looking sexy hair.

Rated 4 out of 5 by from Good Product I have very fine and thinning hair with no body at all. I have tried a lot of products to try to get some volume in my hair and this is one of the products I like the best. It is light and doesn't weigh my hair down. My only issue is the price. I think $42 is a lot of money compared to some other equally good products on the market.

Rated 5 out of 5 by from Lightweight and Volumizing I love this product because it is so lightweight, which is perfect for fine hair. You get subtle volumizing properties without weighing hair down later. It also smells delightful.

Rated 5 out of 5 by from Love it! I purchased, and am using, this treatment mousse in conjunction with the shampoo and masque in the same family. I am in love with the Densifique line and think it has worked wonders for my hair. This mousse gave my hair light body, without weighing my hair down or making it feel crunchy like some mousses can. With other mousses I have used in the past, I notice my hair takes additional time to blow dry, but I do not notice that with this product at all. I blow dry my hair and then just run a flat iron over it to smooth and curl the ends under and my hair looked awesome. It did not look limp or flat, but full and smooth. It held style better than ever and even my 2nd day hair looked good! I am in love with Densifique line and highly recommend it!!!

Rated 5 out of 5 by from Love it! I love this product! Makes my hair seem fuller and easy to style. Doesn't leave my hair oily feeling. It is a bit pricey, but as I don't style my hair daily I don't mind the price!
