Find your application area

Where do you want fuller-looking coverage?

Choose an area for a quick application tip. Hair fibers work best where existing hair is present for the fibers to cling to and blend with.

Crown Part line Hairline and temples

For the crown

Start with dry, styled hair. Apply a small amount over the sparse-looking area, then check the result from more than one angle before adding more.

For a visible part

Create your usual part first. Apply lightly along the sparse-looking section and blend gently so the finish follows your natural part.

For the hairline or temples

Use extra control and a light touch near the edge. Build gradually and avoid overapplying directly onto bare skin for a softer-looking finish.

Best starting pointDry hair that is already styled close to your finished look.

Best techniqueApply less than you think you need, check, then build slowly.

Best matchChoose the shade closest to your roots or application area.

Interactive shade explorer

Start with the colour at your roots.

Tap the closest shade family for a matching tip. These on-screen colours are a guide only and may display differently depending on your device and lighting.

Black Dark Brown Medium Brown Light Brown Blond Grey White

Black: best suited to hair that appears consistently black at the root, rather than very dark brown in bright light.

Dark Brown: consider this if your roots are deep brown but do not read as fully black.

Medium Brown: a useful starting point for balanced brown roots that are neither especially dark nor light.

Light Brown: consider this for lighter brown roots. Match the application area, not sun-lightened ends.

Blond: match the shade near the root and part line, since blond lengths can vary significantly.

Grey: consider this when your application area is predominantly grey or salt-and-pepper.

White: best suited when the application area appears predominantly white rather than grey.

A four-step routine

Style. Apply. Blend. Set.

A natural-looking finish usually comes from a light, gradual application rather than trying to reach full coverage in one pass.

Style first

Begin with dry hair and shape it close to how you want the finished style to look.

Apply gradually

Add a small amount where you want fuller-looking coverage. Pause before adding more.

Blend lightly

Use your fingers or a comb with a gentle touch to soften and refine the finish.

Set if needed

Mist FiberHolder Spray lightly after you are happy with the coverage, then let it dry.

Both options use the same Hair Building Fibers. The difference is whether you already have a finishing product or want the fiber-and-spray routine together.

Questions, answered

Before your first application

How do I choose the closest shade?

Match the fibers to your roots or the sparse-looking application area, not lighter ends. If you are between shades or unsure, use the Shade Matching Guide before ordering.

Do hair fibers work on completely bare areas?

Hair fibers work best where existing hair is present for the fibers to cling to and blend with. Coverage on very sparse or bare areas may be limited.

Do I need FiberHolder Spray?

You can use the fibers on their own. FiberHolder Spray is an optional finishing step that helps set the look, especially for longer days, work, photos, or events.

Are they waterproof or transfer-proof?

No cosmetic styling result should be treated as completely waterproof or transfer-proof. Humidity, perspiration, rain, rubbing, brushing, hats, helmets, and other activity can affect wear. Avoid touching the area excessively and let any finishing spray dry before contact with clothing.

How do I remove the fibers?

Wash them out during your normal shampoo routine. Avoid aggressive rubbing around the application area.

Can I use them every day?

They are intended as a temporary cosmetic styling product. Follow the label directions, avoid inhalation and eye contact, and discontinue use if irritation occurs. Ask a qualified healthcare professional about individual scalp or medical concerns.

Are hair fibers a hair-loss treatment?

No. Hair Building Fibers are temporary cosmetic styling products. They do not regrow hair, stop hair loss, or treat scalp or medical conditions.
