Is this product made for me?

If you clean up fiber smudges with your fingers, you're smearing them around.

  • You use Hair Fibers

  • You want sharp, clean hairline edges

  • You have a beard to keep in line

How is it different from using your fingers?

Your fingers smear. A brush lifts.

Fibers stick to your fingers and leave marks on your skin. These bristles set the fibers into your hair and wipe away the rest, so nothing shows.

  • Sets fibers. Blends them into your hair.

  • Wipes smudges. Clean skin in one pass.

  • Grooms your beard. Every hair goes the same way.

  • Sharp hairline. Narrow head that gets right to the edge.

How to use

  1. Apply Hair Fibers to dry hair. Use the Card or the Applicator for a clean result.

  2. Brush lightly over the area to set the fibers.

  3. Flick away any smudges on your forehead or temples.

  4. Lock it in with Fiber Fixator.

  5. On your beard, brush in the direction it grows.

no more black marks on my forehead

I always ended up with little black marks on my forehead after my fibers, and wiping with my fingers made it worse. One flick with this and it's gone. Should've ordered it with the fibers from day one

doesn't brush the fibers out

was worried it would just brush everything off lol. you go light and it actually sets them into your hair. Fiber Lock Spray on top and it stays put all day at uni

use it more on my beard lol

Bought it for the fibers, now I use it more on my beard lol. Brush in the direction it grows and every hair lies the same way, looks way tidier on camera for my work calls

my fingers were the problem

used to fix everything with my fingers and they'd end up black, then I'd touch my face and make it worse. now my fingers stay clean and so does my forehead. so simple

a year of toilet paper lol

-1 star only because it's 8€ and I spent a whole year wiping my forehead with toilet paper before buying it. I feel stupid. Best 8 euros in my bathroom

beard edges look fresh

I run it along my beard line after trimming and every hair lies flat, the edge looks freshly done. 8 euros for that is nothing

-1 because my cousin uses it on his beard every time he comes over, and he comes over a lot. Got him his own, problem solved. Does the job perfectly

stopped thinking about my temples

22 and my temples started going back. Hair Fibers, then a light brush over the edge, and honestly I've stopped thinking about it. Even under the lights at the club nothing shows

my hairline just looks like my hair

my temples are thinning a bit (24, thanks genetics). I was worried the edge of the fibers would look fake. a light brush over it and it blends right in, now it just looks like my hair

8 euros, don't skip it

it's 8 euros and it's the thing that made the whole fiber routine click for me. spent 2 weeks messing around before I bought it. don't be me

narrow enough for the edge

The head is narrow so you can get right to the edge of the hairline without messing up the rest. That's what I could never do with a normal brush

weighs nothing, always in my bag

it weighs nothing so it lives in the side pocket of my gym bag. after the shower I dry my hair, fibers, quick brush, done before anyone's out of the changing room

easy to keep clean

tap it on the edge of the sink and the fibers fall out, rinse it once in a while. there's a little hole in the handle so it hangs on a hook by my mirror instead of rolling around in a drawer

Verified customer

want it in more colours

4 stars only because I want more colours, the black one looks so clean on my sink I'd collect them lol. Does exactly what it should, sets the fibers and my forehead stays clean

Verified customer

dense bristles actually pick them up

The bristles are dense so it lifts the loose fibers off instead of pushing them around. The random brushes I tried before just spread them over my skin
