Frequently Asked Questions (FAQs)

1. Does hair building fibers work?

Although hair fibers might help to provide the illusion of extra density when you style hair, they have no impact on hair growth and won't help to stop male pattern baldness.

2. Do hair fibers work on bald spots?

Toppik Hair Building Fibers are specifically formulated to instantly hide hair loss like bald spots. Fibers have an electromagnetic charge so that they cling to your existing hair, making it look thicker and fuller. And since they come in nine shades, they can be blended to match almost any hair color.

3. How long do hair fibers last?

The fibers will stay in your hair overnight with only a minimal need for touch-ups in the morning. If you are using it every day, a 12g bottle of Toppik Hair Building Fibers will last about 30 days, and a 27.5g bottle will last about 60 days.
