THICK FIBER instantly adds visible volume to thinning areas by bonding lightweight keratin fibres to your natural hair. It’s a quick cosmetic solution for a fuller-looking hairline and immediate confidence without chemical treatments.

No—when used as directed, THICK FIBER is a topical cosmetic product made from natural keratin and is not known to cause long-term hair damage. Avoid applying to irritated or open scalp wounds, and remove the fibres with shampoo at the end of the day to keep the scalp clean.

Same answer as above: THICK FIBER is a cosmetic keratin powder and generally does not damage hair when used correctly. Keep the scalp clean and rinse out nightly to avoid product buildup.

Yes. For best results, style your hair first (dry) and then apply THICK FIBER as the final step. After applying the fibres, you can use a light setting spray to help secure them. Avoid heavy, oily products before application as they can reduce the fibres’ ability to cling to hair.

Yes — you can blend two or more shades to achieve a closer match to your natural color or to create subtle highlights. Mix a small amount first on your hand to preview the result before applying to the scalp.

Apply THICK FIBER after heat styling. High heat from flat irons or curling tongs can disturb the powder and reduce its hold. If you must use a hair dryer after application, use it on a low setting and from a distance; ideally, finish styling first, then apply fibres and a light spray to set them.

Longevity depends on usage frequency and coverage area. As a rough guide, a 25g bottle often lasts anywhere from 1 to 3 months for daily touch-ups on typical thinning areas. Heavy daily use or covering large areas will reduce that timeframe.

No. For best adhesion and an even finish, apply THICK FIBER to completely dry hair. Moisture prevents the fibres from building and bonding correctly.

THICK FIBER is rain-resistant but not fully water-proof. It’s formulated to resist light rain and sweat, but heavy rain, swimming, or prolonged water exposure will wash the fibres out because the product is a powder-like substance.

THICK FIBER is a cosmetic product and is generally safe for topical use. However, if you are using prescription or topical medications on your scalp (for example, treatments for hair loss or skin conditions), consult your doctor or pharmacist before combining products. In many cases you should let topical medication fully absorb and dry before applying fibres.

THICK FIBER needs existing hair strands to cling to, so it is not effective on completely bald areas. For very sparse or nearly bald regions, consider hair toppers, wigs, or scalp micropigmentation. THICK FIBER works best when there is some hair to attach to.

No. THICK FIBER is an instant cosmetic concealer that improves the appearance of hair density. It does not stimulate hair growth or treat the underlying causes of hair loss. For hair regrowth options, consult a medical professional about clinically proven treatments.
