Hair fibres are a quick, temporary way to make thinning areas look fuller. Applied well, they blend with your own hair and look natural. Applied badly, they can look patchy or powdery. This guide covers everything you need to get a good result every time.
What you'll need
- Your hair fibre kit, in a shade that matches your hair
- A hairbrush or comb
- A hold or fixing spray (recommended)
- A mirror, and good lighting
- Optional: a spray applicator pump for more even coverage
Step-by-step
1. Start with clean, completely dry hair
Fibres cling best to dry hair. Wet or oily hair can make them clump, so wash and dry your hair first, then style it as you normally would.
2. Part and style before you apply
Set your parting and style your hair before adding fibres. It is much harder to change your hairstyle afterwards without disturbing the fibres.
3. Shake a small amount into your palm
You need much less than you think. Start with a small pinch and build up. Over-applying is the most common mistake.
4. Sprinkle or spray over the thinning area
Hold the bottle 5 to 10 cm above your head and sprinkle lightly, or use an applicator pump for a finer, more even mist. Work in thin layers over the areas you want to cover, such as the crown, the parting or the hairline.
5. Pat, don't rub
Gently pat the fibres into your hair with your fingertips so they bind to your hair. Rubbing can clump them or push them down to the scalp.
6. Blend the edges
Use a comb or a soft brush to gently blend the edges where the fibres meet your natural hair. This is what makes the result look seamless.
7. Lock it in
Finish with a light mist of hold spray, kept a little distance away from your head. This helps the fibres stay in place through the day, and it helps with wind and light rain.
Tips for a natural finish
- Build in layers. Two light applications look better than one heavy one.
- Check your shade. Choose the colour that matches your hair in daylight. If you are between shades, go for the slightly lighter one.
- Watch the hairline. Use the smallest amount here, since this is where it is most noticeable.
- Keep the bottle dry. Close it tightly after use and store it somewhere cool and dry.
- Check in daylight. Bathroom lighting can hide excess powder, so take a quick look by a window.
Common mistakes to avoid
- Using too much. More fibres do not mean more coverage. They mean more powder.
- Applying to damp or oily hair. This causes clumping.
- Skipping the blend. A visible edge looks unnatural.
- Using it in heavy rain. Fibres are not designed to be fully waterproof, so carry an umbrella.
How to remove hair fibres
Fibres wash out with normal shampooing. Wet your hair, lather up twice and rinse thoroughly. If you find you have fibres left on your scalp, a gentle scrub with your fingertips will help.
Frequently asked questions
Are hair fibres a treatment for hair loss?
No. Hair fibres are a cosmetic product that makes hair look thicker. They do not change how your hair grows. If you are worried about hair loss, speak to your GP or a pharmacist.
Will they stain my pillow or clothes?
A small amount of transfer is possible, especially if you have not locked the fibres in with hold spray. Brush your hair before bed and consider a dark pillowcase on days when you have applied fibres.
How long do they last?
They last until your next wash. A good hold spray helps them stay put through the day.
Can I use them every day?
Yes, most people do. Wash your hair and scalp thoroughly between uses.
What if I have a sensitive scalp?
Do a small patch test first, and stop using the product if you notice any irritation.
