How to Use Hair Fibers for a Fuller Look: Step-by-Step
When your scalp shows through thinner areas, especially in photos or bright light, hair building fibers can help it look fuller in seconds. They are a cosmetic concealer: they cling to your existing hair and wash out with shampoo. Here is how to use hair fibers for a natural-looking result.
What hair fibers are
Hair fibers are tiny coloured fibers that you shake or spray onto dry hair. They stick to the hair you already have, which makes it look thicker and helps hide the scalp. They are not a treatment and do not change how your hair grows.
Step-by-step
- Start with clean, completely dry hair, styled the way you want to wear it.
- Choose your shade. Pick the shade closest to your hair. If you are between two, the darker shade usually looks more natural at the roots.
- Apply. Hold the bottle or applicator about 10 to 15 cm (4 to 6 inches) above the thinner area and shake or spray gently.
- Build up slowly. Add a little at a time until the scalp looks covered. Too much at once can look powdery.
- Pat lightly. Use your fingertips to press the fibers into the hair. Do not rub.
- Tidy up. Brush away any fibers on your forehead or around the hairline.
- Lock it in. A light mist of hairspray helps the fibers stay in place in wind and light rain.
Using an applicator spray
An applicator nozzle lets you place the fibers more precisely, for example along a parting or at the crown, and reduces mess. Fit it onto the bottle and press gently in short bursts.
Tips for a natural look
- Apply in good light, ideally with a hand mirror for the crown.
- Fibers work best where there is still some hair for them to cling to.
- Protect light-coloured clothes while applying.
- Refill bags are a lower-cost way to top up your bottle.
Removing hair fibers
Fibers wash out with regular shampoo. Most people apply them fresh each day.
Good to know
Hair fibers are a cosmetic product for appearance only. Results vary. If you notice new or sudden hair loss, please speak to a doctor or dermatologist. Stop using the product if your scalp becomes irritated.

Frequently asked questions
Do hair fibers come off in the rain?
Light rain and wind are usually fine, especially with a mist of hairspray. Heavy rain or swimming will wash them out.
Can I use hair fibers every day?
Yes. Apply them to clean, dry hair and wash them out with shampoo.
Do hair fibers help hair grow?
No. They are a cosmetic concealer that changes how hair looks. They do not affect growth.
Which shade should I choose?
Choose the shade closest to your hair colour. If you are between two, the darker one usually blends better at the roots.
