Hair Building Fibres disguise thinning hair naturally by blending keratin-derived fibres with your existing strands. SureThik® uses natural keratin micro-fibres to build dramatic density and volume, giving men and women full, natural-looking coverage without compromising safety or effectiveness.

SureThik® fibres bond electrostatically to your hair, boosting structure and volume even on areas with tiny vellus hairs. The fibres resist rain, wind, and perspiration while washing out easily with shampoo. They can be used with hair loss medications and do not require special styling products. Our SureStay Technology ensures the fibres stay in place maintaining coverage in all conditions. You can use SureThik® safely with topical hairloss treatments and even after hair transplant surgery.

Benefits
Ingredients: Keratin, Sodium Bicarbonate, Silica, Iron Oxides (CI77499, CI77491, CI77492)

Applying the Fibers:

1: After washing your hair, air-dry, or blow-dry your hair completely. SureThik®should be applied to dry hair.

2: There are 8 different colors to choose from. We find that for best coverage select the same or one shade darker than your own hair.

3: Simply shake the hair fibers over the areas of thinning. As you apply SureThik®to your scalp – you will see bald patches and thinning hair fade away before your eyes.

4: After you are done applying SureThik®gently brush or pat down the fibers through your hair, the fibers disappear and blend in a completely undetectable manner. The final result is a totally natural-looking full head of hair

5: Use our SureThik®Holding Spray to give your hair some shine and to help lock in the fibers to ensure a finished look.

Pro Tip: Make sure to keep the dispenser only a few inches from the hair, lift sections of hair with a comb or your fingers to expose thinning areas, gently tap the bottle to help dispense the fibers evenly.

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 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.

3. 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.

4. 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.

5. 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.

Confidence Booster

The product has been amazing. It’s legitimately taken 5-7 years off my looks. It’s been a major confidence booster and I couldn’t be more happier. I cannot believe I did not start sooner. It stays on all day and I’ve even gotten in the sauna with it and it didn’t come off.
