Frequently Asked Questions
How long does Keratherapy Fiber Hair Thickener last?
Keratherapy Fiber Hair Thickener lastsuntil your next shampoo. As a temporary, wash-out product, the keratin-infused fibers cling to existing hair strands and wash out with shampoo.
How long will Toppik Hair Building Fibers stay in place?
Yes, you can use Keratherapy Fiber Hair Thickener with other styling products, but the order of application is important. Applying it correctly ensures the fibers attach to your hair rather than clumping together with wet styling products.
Is this suitable for both men and women?
Yes, Keratherapy Fiber Hair Thickener is designed for both men and women. The product is a unisex solution meant to conceal thinning hair and add density regardless of the user's gender.
How much product should I expect to use per application?
It is not possible to give a precise amount of Keratherapy Fiber Hair Thickener to use per application, as the correct quantity is highly individual. It depends entirely on the size of the area you need to cover and the level of density you want to achieve.
The most important rule is tostart with a small amount and build up in light layers. Using too much at once will make the results look unnatural and can cause the product to clump.
Will this product transfer to clothing or pillows?
Yes, a little transfer is possible. Keratherapy Fiber Hair Thickener can transfer to clothing, pillows, and other surfaces, especially if not applied correctly or set with hairspray. The fibers are designed to cling to hair, but friction from contact can cause them to rub off.
However, there are ways to minimize or prevent this transfer.
To prevent transfer:
Finish with hairspray. Applying a light mist of hairspray after the fibers are in place is highly recommended. This locks the fibers to the hair and significantly reduces the chance of them rubbing off on fabrics.
Let the product dry completely. After spraying the fibers, allow them to set and dry for 2–3 minutes before touching your hair or getting dressed.
Avoid touching the treated area. Once applied, try not to touch your hair in the areas where the fibers have been sprayed. Rubbing or scratching your head can dislodge the fibers.
Wash before bed. For the most security, it is best to wash your hair before going to bed to completely remove the product. This also helps maintain scalp health and avoids potential buildup.
Dust off any stray fibers. If any fibers get on your clothes during application, they can typically be dusted off easily, as they don't permanently stain fabrics.
