Have a question?
Will the fibers fall off if it rains or I sweat?
Nope! Densify fibers are sweat-proof, wind-resistant, and water-resistant. They’ll stay in place throughout your day, whether you're working out, dancing, or caught in light rain. For best results, we recommend using a light hair spray to lock them in.
Can I use them if I have very short hair or thinning at the crown?
Yes, absolutely. Our fibers work best when there's at least some hair for the fibers to cling to. Even if your hair is very short or thinning at the crown, the fibers will bind to existing strands and create a fuller appearance instantly.
How long does a bottle last?
Each 25g bottle typically lasts around 30 to 45 days with daily use, depending on how much product you apply and the size of the thinning area you're covering.
Will it match my hair color?
We offer multiple natural-looking shades that blend seamlessly with most hair colors. If you're between two colors, go with the darker shade—it blends more easily and gives a fuller look. You can also mix two shades for a custom match.
How do I remove it?
Super simple—just wash your hair with shampoo and water. The fibers rinse out completely without leaving residue or buildup.
