Product Description

Keratin Hair Building Fibers instantly give you a thick and beautiful new head of hair. It really is just that easy. No more embarrassment over thinning areas and no more excuses. As the protein fibers fuse to your natural hair, you’re thinning areas will disappear like magic. Your gorgeous new hair is perspiration and weather resistant, and the fibers are removed easily with a single shampoo.

No matter what your hair color, Hairthickener offers a perfect match of hair building fibers, offering 10 available shades to fill in all of your thinning areas. Perfect for men and women who want to rebuild their hair and regain the confidence they had with a thick and natural head of hair.

Our fibers are made of all natural organic keratin protein, the same protein that hair is made of. The fibers are charged with static electricity so they intertwine with your own hair and bond securely. Just shake on the fibers and they stay in place all day, all night.

The fibers are undetectable even as close as a few inches away. The Hair thickener hair fibers look exactly like your hair and bond with your existing hair. You will not have any embarrassing moments. Once the fibers are set in place they will not come off with normal pat to your hair, or with perspiration, or wind. Utilizing the fiber hold spray will increase the bond between the hair building fibers and your natural hair.

Hair Thickener Fiber Application in 3 Easy Steps

Step 1: Wash and dry hair. Shake liberally over thinning areas. Gently tap, shake, or sprinkle the bottle of fibers at about 45 degrees, and hold it 3 inches above your thin areas to dispense fibers.

Step 2: Once the Fiber is applied, gently pat hair if necessary to disperse the hair fibers evenly within your hair.

Step 3: Apply  fiber hold Spray to secure the fibers.

    Once I tried the Hairthickener system I was hooked and the subscription plan makes it really easy to always have the hair fibers on hand.

    Thought I would have a hard time matching my hair color, but there are lots of colors to choose from. Found a perfect match and no one can ever tell the difference.

    The hair fibers are really easy to apply. I use the hairthickener 360 mirror and I can get to the hard to reach areas in a snap.

    At first I was just ordering the hair fibers one bottle at a time, but I like hairthickener so much it was an easy decision to switch over the subscription.
