Trustpilot 4.7 'Excellent'
Why you'll love them
Designed for hair that's thinned at the sides or temples. Wider, softer, lighter than face framers — and just as invisible.
2.5-inch wide base
Covers the side of your head in one piece. No fiddling with multiple clips.
Lightweight on fine hair
20g of soft Remy human hair. Sits comfortably without pulling on what you have.
30 seconds to fit
Snap the mini-clips open, slide into place, snap shut. That's it.
Real human hair
100% Remy. You can curl, straighten, wash and style it just like your own.
The volume you used to have. Without the wait.
If your sides have thinned — from perimenopause, stress, hormones, or just time — the Fill-Ins put the density back. They sit flat against your head, blend into the hair you have, and disappear.
No regrowth treatments. No salon appointments. No bonding glue.
How to put them in — 3 simple steps
Takes about 30 seconds once you've done it once. No mirror skills required.
Section
Part your hair where it naturally falls. Lift the top layer at the side of your head.
Clip
Snap the mini-clips open. Place the weft flat against the side of your head, about 1 inch back from the hairline. Snap the clips shut.
Blend
Drop your own hair back over the top. Brush through. Style as normal — they're heat-safe.
Front or sides — which one do I need?
If you're not sure where your thinning is, look in the mirror with your hair parted normally. Where does the scalp show through most?
"I've been losing volume at the sides for about two years and tried everything. These are the first thing that actually fills it in without anyone knowing."
Sarah, Verified buyer
"Sceptical at first — but they took 30 seconds to put in and the colour matched perfectly. My hairdresser couldn't tell."
Janet, Verified buyer
"Bought the Framers last year. Bought these the day they launched. Wear them both daily. Worth every penny."
Helen, Verified buyer

How to care for them
Brushing: Use a wide-tooth comb. Start at the ends and work up. Avoid fine-tooth combs.
Washing: Use lukewarm water and a gentle shampoo (not a volumising one). Wash every 2–3 weeks with daily wear.
Conditioning: Apply to the mid-lengths and ends only. Avoid the clip area.
Drying: Air dry where possible. If using heat, low setting and use a thermal protectant.
Avoid: Alcohol-based products, bleach or lightener, swimming and rain, sleeping in them.

Will they hold on fine or thinning hair?
Yes. The clips are designed to grip without needing thick hair underneath. They're also lightweight (20g across two pieces) so they don't pull or drag — even on very fine hair.
If you find one clip feels loose, there are spare clips in the pack you can swap in. Your hairdresser can also reposition the clips if needed.
Can anyone see them?
No. The clips are miniature and sit flat against your head. Your own hair lies over the top and hides them completely. As long as the colour is matched well, they're invisible.
Can I curl, straighten or colour them?
Curl and straighten — yes, on a low heat with a thermal protectant. They're 100% Remy human hair so they style like your own.
Colouring — we don't recommend bleaching or lightening, as this can damage the hair. Darkening or toning by a professional colourist is fine.
Can I trim my Fill-Ins?
Yes. If they need to be shortened absolutely, however we do advise your local hairdresser doing this to get it spot on.
What's the difference between these and the Face Framers?
Same concept, different position. Face Framers are 1-inch wide and sit at the front of your head — for thinning at the parting or money-piece highlights. The Fill-Ins are 2.5 inches wide and sit at the sides — for thinning at the temples or above the ears. Many customers wear both.
I'm struggling to put them in
You need to 'SNAP' the clip open, get them in place, then 'SNAP' the clip shut onto your own hair. Watch the application video further up this page.
I'm worried they'll fall out
The clips hold firmly. They're lightweight and comfortable — you won't feel them, but they won't move either.
