Why you'll love them

Designed for hair that's thinned at the sides or temples. Wider, softer, lighter than Face Framing Layers — 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.

Before and after showing thinned sides filled in with Naturyl Fill-Ins

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.

30s to fit
20g real human hair
14" length

How to put them in — 3 simple steps

Takes about 30 seconds once you've done it once. No mirror skills required.

1

Section

Part your hair where it naturally falls. Lift the top layer at the side of your head.

2

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.

3

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?

For the front

Face Framing Layers

Best for thinning at the front, broken edges, wispy "baby hairs" around the face, or adding a money-piece highlight.

  • →1-inch base — narrower
  • →15g — extra lightweight
  • →Sits at the front, around your part
  • →2 pieces per pack
Shop Face Framing Layers →
For the sides

Thinning Hair Fill-Ins

Best for thinning at the sides, temples, or above the ears. Adds volume across a wider area in one piece.

  • →2.5-inch base — wider coverage
  • →20g — still lightweight
  • →Sits at the side
  • →2 pieces per pack

★★★★★

"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 Face Framing Layers last year. Bought these the day they launched. Wear them both daily. Worth every penny."

Helen, Verified buyer

Everything else you need to know

Care, delivery, returns, and the questions we get asked most.

What's in the pack
  • 2 x Thinning Hair Fill-Ins (1 for each side)
  • 14 inches long, 20 grams of Remy human hair, 2.5-inch base
  • Spare clips
  • Storage bag
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 Framing Layers?

Same concept, different position. Face Framing Layers 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.

I need help matching the colour

Press the chat button at the bottom right of the screen and select "Colour Match." Tell us you're looking for the Thinning Hair Fill-Ins and we'll help you pick the right shade.

All colour exchanges are free if you get it wrong first time.

Customers praised these clip-in extensions for thinning hair, highlighting "perfect colour match" and natural appearance. Shoppers noted they're "easy to use," lightweight, and "invisible" when worn. Many reported increased confidence, with one saying "for the first time in my life I actually like my hair." One concern: colour accuracy in mixed shades may vary from photos.

As per usual brilliant service and brilliant. Colour match. I have the face framers, side clips in and wire extensions. I ve had to take th3 wire off and just use the clips just easier for myself.

I was really surprised how good these are. My hair is thinning due to weight loss and theses really make a difference to my confidence and are very easy to use. I’m so impressed I’ve also ordered a halo hairpiece.

Absolutely fabulous quality

Absolutely fabulous quality. I wear just these daily and it completely transforms my hair. I have thick hair but I have lost volume at the front due to breakage and age. Love these. Best purchase I have made.

I loved these so much I bought the whole head of extensions! Perfect colour match using the photo I provided. Super fast delivery, and beautiful hair. I spent a fortune on a wig when I lost all my hair to cancer, and now it’s regrown I can use extensions, these are just as good quality as my wig, if not better. A great company, I’d recommend to anyone!

Absolutely made up with my hair extensions! I've even taken them on holiday with me—they're brilliant for nights out and perfect for adding a bit of body to my hair when it feels flat in between washes. They match my hair colour perfectly, are so easy to use, and the ordering process was simple with very quick delivery. I would 100% recommend buying these!
