Defines My Waves/Curls & Adds Volume To My Long Hair

I have enjoyed using the Four Reasons Professional Fiber Mousse. I have long, fine hair with multiple textures in it. I have waves and curls with varying textures throughout my hair. I decided to try this mousse out to see how it would do with defining my waves/curls, and to see if it could add some volume as well. I especially wanted to add volume to my hair when it was in a ponytail. I followed the directions and blowdryed my hair after applying the mousse. The mousse definitely did add more volume to my hair when it was down or already pulled up in a slicked-back ponytail. Blowdrying definitely helped to add definition and volume to my fine hair. This product even helps to add volume to my hair in-between washes, which is nice, because dry shampoo only seems to make my hair feel more dirty and gross.Overall, I really like this mousse. It is a versatile hair styling product, and it smells nice and fresh. I would recommend giving it a try.

Nice volume!

I love that this is a vegan product! Great for fine hair. Mousse in general tends to be great for adding volume to my hair, and this one was no different. Overall a great buy!

Great volumizing product

This mousse is great for volumizing—my daughter has thin, fine hair and it really gives her a lift!

Thick and a bit sticky

This mousse comes out all foamy, as it should. The foam is thick and a bit sticky, but my hairstyle held up for the whole day. I'm quite happy with it.

Better Than Oribe!

My fab stylist used this mousse on me, and I was very, very surprised by the result...I have long, fine layered curly hair, and my issue has always been about maintaining volume after styling. Enter Fiber Mousse - my hair has kept this glorious fullness for over a week, and it still looks good on day 10 (that has never happened). Plus, my hair is soft to the touch, and that has never happened either...usually soft hair means the hold won't last, but not with this mousse. I've been using Oribe's volumizing mousse, but the fiber mousse sells for a far more reasonable price. No one paid me to leave this review, and I don't know anyone in this company. My review is authentic, and I'm thrilled that my stylist used the product on me that she, randomly, found on Amazon. Score!

Have any questions about Four Reasons?

Color Mask Treatments are pigmented deep conditioners, and Color Mask Shampoos are pigmented shampoos.

Color Masks are specially formulated for color-treated hair, as they perfectly
take into account all that colored hair needs: color refresh and deep
conditioning!

Color Masks don't contain harsh chemicals like ammonia. Quite the contrary
actually! They gently cleanse and deeply condition and repair hair, while
depositing color pigments to the hair's surface.

Color Masks are intended to tone hair or maintain your existing hair color. We all know that beautiful hair color can fade and lose its vibrancy within a few washes. That's where Color Masks come in! Use in place of regular shampoo or conditioner whenever your hair color needs to be refreshed. Simple as that!
