Very good product. No itching. Works like my toppik hair. Wanted to try it and it actually works almost the same. Its fraction of the price of toppik, and serves the purpose. No greening and nothing bad with it

FAQs

Q: How do I apply Sevich Keratin Hair Building Fibers for the best results?
A: Start with clean, completely dry hair. Lightly shake fibers over thinning areas, then gently pat to help them cling to existing strands. For a more secure finish, mist a light-hold hair spray or fiber-hold spray and let it set before styling as usual.

Q: How long do the fibers last, and are they sweat or water resistant?
A: They stay in place all day under normal conditions and resist light sweat and humidity. Avoid heavy rain, swimming, or vigorous sweating without a finishing spray. Remove easily with shampoo during your next wash and reapply to dry hair.

Q: How do I choose the right shade—and can I mix colors?
A: Pick the closest match to your root color (not the faded ends). If you’re between shades, start darker (e.g., dark brown vs. black) or mix two shades by applying the darker first, then layering the lighter for a natural gradient.

Q: Will this work on very thin or completely bald areas?
A: Fibers need some hair to latch onto, so they work best on thinning areas with visible strands. On fully bald patches, coverage will be limited. For receding hairlines, apply sparingly and blend well with a brush for a softer edge.

Q: Is it safe for daily use, color-treated hair, and with other styling products?
A: Yes—when used as directed, the keratin fibers are non-irritating and safe on color-treated hair. Avoid contact with eyes and mouth, and keep away from open flames. You can use gels or waxes first, let them dry, then apply fibers; finish with a light spray to lock everything in.
