Thick Fiber Hair Building Fibers — Grey 0.98 oz | Instant Natural-Looking Coverage, Sweat-Resistant

Thick Fiber Hair Building Fibers (Grey, 0.98 oz) are lightweight keratin fibers designed to instantly conceal thinning areas and create the look of fuller hair until washed out.

Thick Fiber's grey hair-building fibers use colored keratin to blend with your existing hair, adding density and natural-looking coverage in seconds. The 0.98 ounce bottle is sized for daily touch-ups or targeted coverage, and the formula resists sweat, light rain, and wind so results last through normal activities until you shampoo it out. Application is simple and noninvasive, making this product an easy part of morning routines for men and women with thinning hair.

How quickly will I see results when using these fibers?

Results are immediate — fibers attach to existing hair strands to create visual thickness right after application. Because the fibers are colored keratin, they blend with your hair rather than sit on the scalp as powder does.

• Instant coverage: visible thickening in seconds
• Use on dry hair for best adhesion
• Works on individual thinning patches, partlines, and receding temples

Will the fibers stay on in rain, wind, or during exercise?

Thick Fiber is formulated to resist everyday moisture, sweat, and light wind so the appearance holds up during active days. The fibers remain until removed with shampoo, though heavy rain or vigorous rubbing can reduce coverage.

• Sweat-resistant: suitable for light workouts and daily activity
• Wind and light rain resistant for short outdoor exposure
• Secure until washed out with regular shampoo

How do I apply Thick Fiber for the most natural result?

Shake the bottle sideways before use, then sprinkle fibers onto dry, styled hair in the direction of hair growth. Lightly pat to help fibers interlock with existing strands, and finish with a styling spray for greater hold and blend.

• Shake sideways to loosen fibers evenly
• Apply in a salt-and-pepper motion over thinning areas
• Pat gently and optionally lock with a styling spray

What is inside the bottle and is it safe for daily use?

Thick Fiber uses natural keratin protein fibers — the same building block as natural hair — colored to match your shade. The product avoids harsh chemicals and is designed for topical use on thinning areas; remove with shampoo when desired.

• Made from natural keratin protein fibers
• No harsh chemicals included
• Anti-itch formulation and sweat-resistant finish
