1. What are SureThik Hair Thickening Fibers made of?
SureThik fibers are made from natural, keratin protein designed to mimic real hair. They’re lightweight, safe, and cling securely to existing strands.
2. How do Hair Thickening Fibers work?
The fibers cling to existing hair strands, helping add visible density and reduce the appearance of thinning areas.
3. Will Hair Thickening Fibers work on bald areas?
Hair Fibers need some existing hair to attach to. They work best on thinning areas where hair is still present and are not designed to cover completely bald areas.
4. Can Hair Thickening Fibers be used by both men and women?
Yes. They can be used by anyone looking to make fine or thinning hair appear fuller and thicker.
5. Will the fibers look natural or noticeable?
They blend seamlessly with your own hair. SureThik fibers are designed to match hair color and texture, giving a fuller, natural appearance without looking powdery or artificial.
6. How do I choose the right shade?
Choose the shade that most closely matches your existing hair. The fibers blend with your hair rather than your scalp, so matching your hair color generally provides the most natural result.
7. Can I mix two Hair Fiber shades together?
Yes. Mixing shades can help create a more customized color match, especially if your hair falls between two shades.
8. How do I apply Hair Thickening Fibers?
Apply to clean, dry hair. Shake the fibers directly over thinning areas, or use the SURETHIK Pump Applicator for more precise application around the hairline. Gently pat or blend as needed, then finish with Fiber Holding Spray.
9. Can I use Hair Thickening Fibers on my hairline?
Yes. For the hairline, we recommend using the Pump Applicator with the fan nozzle and Hairline Tool for more precise, natural-looking coverage.
10. Should I apply Hair Thickening Fibers to wet or dry hair?
Always apply Hair Fibers to dry hair. Applying them to wet or damp hair can affect how well the fibers attach and blend.
11. Can I brush or style my hair after applying the fibers?
For best results, complete most of your styling before applying the fibers. Light adjustments can be made afterward, but excessive brushing or combing may displace some of the fibers.
12. Can I use SureThik fibers with other hair products?
Yes. You can use them with gels, mousses, waxes, and sprays. For best results, apply styling products first, let them dry, then apply fibers and finish with a fiber-holding spray.
13. Are SureThik fibers safe for sensitive scalps or color-treated hair?
Absolutely. The fibers are gentle, non-irritating, and safe for all hair types—including chemically treated or colored hair. They won’t affect your color or cause buildup.
14. Will Hair Thickening Fibers make my hair grow?
No. Hair Fibers are a cosmetic hair loss concealer that instantly creates the appearance of fuller hair. They do not stimulate or regrow hair.
15. How long do the fibers stay in place?
When applied to dry hair and set with a holding spray, the fibers stay in place all day. They’re resistant to sweat, wind, and humidity—yet wash out easily with shampoo.
16. Are Hair Thickening Fibers waterproof?
They are water-resistant, but not waterproof. Light moisture should not be a problem, but swimming, or soaking the hair can cause the fibers to come off.
17. Will Hair Thickening Fibers come off on my pillow?
Once properly applied and set with Fiber Holding Spray, transfer should be minimal. If you do notice a few fibers on your pillow, don’t worry, they will not stain and will easily come out in the wash.
18. How do I remove Hair Thickening Fibers?
Simply wash your hair with shampoo as you normally would.
19. What is SureThik Fiber Holding Spray?
SureThik Fiber Holding Spray is a lightweight, alcohol-free finishing spray designed to lock hair fibers in place.
20. Do I need to use Fiber Holding Spray?
It is recommended. Fiber Holding Spray helps provide additional hold and keeps the fibers in place throughout the day.
21.How do I use it with hair fibers?
After applying SureThik fibers, spray a light, even layer over the fibers to lock them in place. Avoid oversaturating for best results.
22. How long does the hold last?
When applied properly, the spray provides a full day of hold, resisting sweat, wind, and humidity. It stays effective until you wash your hair.
23. Will it make my hair sticky or stiff?
No. The lightweight, non-sticky formula keeps hair looking natural while holding fibers securely in place.
24. Is it safe for all hair types?
Yes. The alcohol-free, gentle formula is safe for all hair types, including color-treated or chemically processed hair.
25.Can I use my regular hairspray with Hair Thickening Fibers?
Yes. Apply the Hair Fibers first, then use a holding spray or hairspray as a finishing step. Avoid spraying too close to the hair, as this can disturb the fibers.
26.What does the Twist-On Pump Applicator do?
It is designed to help you apply hair fibres more precisely, especially on small areas or thinning spots.
27.Is the Pump Applicator easy to attach?
Yes, it’s very easy. Just twist it onto the fibre bottle, and it’s ready to use.
28. What’s the use of the Hairline Applicator Comb?
It is used to create a clean, natural-looking hairline by blocking extra fibres from falling onto your forehead or skin.
29. Are both the tools beginner-friendly?
Yes, both tools are simple to use and make fibre application faster and precise.
