Touch up your roots. Keratherapy’s keratin-infused colour spray temporarily covers visible grays and root regrowth between salon visits.
Add targeted fullness. Toppik’s loose keratin fibers cling to existing strands and make thinning areas look fuller. Both products wash out with shampoo.
For precision at the hairline, use the Toppik Hairline Optimizer. Finish with an optional light mist of Toppik FiberHold Spray.

Shake the Keratherapy can well. On dry, styled hair, spray lightly and evenly over visible roots from 6–10 inches (15–25 cm) away. Let it dry for 2–3 minutes.

Once the roots are dry, lightly shake Toppik fibers onto thinning areas at the part, crown or hairline. Gently pat to distribute and add more in light layers if needed.
We offer five versatile shades: Black, Medium to Dark Brown, Light Brown, Blonde, and Auburn Red. For the most natural-looking blend, select the color that most closely matches your natural root color or the darkest tone in your hair.
The temporary colour is designed to last until your next shampoo and washes out with regular shampoo.
Yes. Keratherapy lists the root concealer as suitable for colour-treated hair.
Let the concealer dry completely for 2–3 minutes before touching your roots, brushing, or getting dressed. This helps reduce transfer.
Toppik Hair Building Fibers are made of Keratin protein - the same thing that makes up human hair. The Keratin protein comes from a natural wool source, which is the closest match to human hair.
It is recommended that Toppik Hair Building Fibers be applied after the use of any styling tools such as hairdryers, flat irons or curling irons. Styling products (other than hairspray) should be applied to the hair prior to applying Toppik Hair Building Fibers. Applying gels, mousses, pastes, serums, and the like after applying Fibers may cause shifting the Fibers and could expose the areas that were meant to be covered. Let styling products dry before applying Fibers.
Yes, you can mix different shades of Hair Building Fibers. In fact, it is often encouraged to mix different shades in order to find the closest match to your own color, especially when working with blonde or gray hair. The product can either be mixed directly in the hair (use the lighter color first, and then layer the darker color over it).
