Hair Thickening Fibers Medium Brown applies natural keratin micro‑fibers that cling to your existing hair, instantly creating the appearance of fuller, thicker hair. It fills in thinning spots and blends naturally while staying put through wind, rain, or sweat — and washes out easily with shampoo.

Size: .53 oz. (15 g) 

Key Benefits: 

• Instantly creates the appearance of thicker, fuller hair by bonding to existing strands.
• Made from all-natural keratin fibers, safe for both men and women, and compatible with hair loss treatments.
• Resistant to wind, rain, and perspiration for long-lasting confidence in any conditions.
• Completely safe for use after hair transplants and washes out easily with shampoo.

How to use:

1. After washing your hair, air-dry or blow-dry completely. SureThik should be applied to dry hair.
2. Choose a color that matches your hair or is one shade darker; there are 8 shades available.
3. Shake the fibers over thinning areas; bald patches and thinning hair will begin to disappear.
4. Gently brush or pat the fibers through your hair to blend them for a natural-looking finish.
5. Optional: Use SureThik Holding Spray to add shine and lock in the fibers.

Pro Tip: Keep the dispenser a few inches from the hair, lift sections to expose thinning areas, and gently tap the bottle to apply fibers evenly.
