Frequently Asked Questions
Everything you need to know about KeraFiber hair solutions.
What are KeraFiber Hair Building Fibers made of?
Our fibers are made of high-grade, natural keratin protein—the same protein found in human hair. They are designed to merge undetectably with your existing hair to create a fuller, thicker appearance.
How long do the fibers stay in place?
KeraFiber stays securely in place until you wash your hair with shampoo. It is resistant to wind, rain, and perspiration, though we recommend using our FiberHold Spray for maximum durability.
How long does shipping take?
Standard shipping typically takes 3-5 business days within the domestic region. International orders may take 7-14 business days depending on the destination and customs processing.
Can I use styling tools with KeraFiber?
Yes. We recommend using blow dryers, flat irons, or curling irons before applying KeraFiber. Once the fibers are applied, you should avoid using high-heat tools directly on the area to maintain the bond.
What is your return policy?
We offer a 30-day satisfaction guarantee. If you are not completely happy with your results or chose the wrong shade, you can return the product for a full refund or exchange.
Which hair colors are available?
KeraFiber comes in 9 versatile shades ranging from Black to Light Blonde and Grey. You can even mix two colors to achieve a custom match for highlighted or salt-and-pepper hair.
