The best hair extensions for thinning at the crown or on top lie flat right where you'd like more fullness and blend naturally with your own hair. Our Invisible Clip-In hair extensions sit on ultra-thin mesh bands that mimic natural hair growth, offering quick coverage at the crown and along the part line, and our Thinning Hair Fill-Ins feature seamless silicone wefts to add natural-looking coverage wherever you need extra fullness, including near the part line and crown. If you'd prefer semi-permanent coverage, Invisible Tape-In hair extensions are ideal for the crown of the head and all over.
Here's how to choose the right type for the area you'd like to fill, how many grams to add, and how to wear each type comfortably.
Which hair extensions hide thinning at the crown or on top?
Start with where you'd like the most coverage. Thinning on top usually shows along the part line, while thinning at the crown shows at the back of the head, where hair grows in a swirl. The table below matches each type to the area where it works best.
| Where you'd like coverage | Bombay Hair option | Why it works | Lengths and weights |
|---|---|---|---|
| At the crown and along the part line | Invisible Clip-In hair extensions | Ultra-thin mesh bands that mimic natural hair growing on the scalp for quick coverage at the crown | 12" 45g, 16" 50g, 18" 55g and 20" 55g |
| Near the part line and crown | Thinning Hair Fill-Ins | Thin, seamless silicone wefts in a 6-piece set of 2 x 4" wefts and 4 x 1.2" wefts, for natural-looking coverage near the part line and crown | 12" 55g, 16" 85g and 20" 100g |
| The crown and all over, semi-permanent | Invisible Tape-In hair extensions | A pre-taped skin weft designed to mimic hair growing from the scalp | 20", in 25g packs of 10 pieces |
| All over, removable | Seamless Clip-In hair extensions | A set of thin, silicone wefts that sit comfortably against the scalp without added bulk | 14" to 24", from 90g to 250g |
| All over, semi-permanent | I-tip hair extensions | A great fit for even thin hair types, applied without heat or glue | 25 pieces of 1g in each pack |
Both Invisible Clip-In hair extensions and Thinning Hair Fill-Ins add coverage at the crown, and the invisible clip-in hair extensions can also be worn along the part line, since the invisible mesh band mimics natural hair growing from the scalp. The difference is in what each set holds: the invisible clip-in hair extensions come as four wefts on mesh bands plus two extra small clips, at 45g to 55g, while the thinning hair fill-ins come as six pieces in two sizes, at 55g to 100g.

Why do Invisible Clip-In hair extensions work so well at the crown?
Our Invisible Clip-In hair extensions are made to give quick coverage at the crown and along the part line. Each weft sits on an ultra-thin, invisible mesh band that rests flat against the scalp and is designed to mimic natural hair growth. Every set comes with four 7 cm wefts and two extra small clips, which lets you place each piece exactly where you'd like more coverage.
To wear them, part your hair where you'd like extra fullness and coverage, attach a weft to the sectioned hair, and snap the clips shut securely. They come in 12", 16", 18" and 20", weighing 45g to 55g, and they're 100% cuticle Remy human hair, double-drawn, thick from root to tip.
When should you choose Thinning Hair Fill-Ins?
Our Thinning Hair Fill-Ins are a lovely choice when you'd like more fullness near your part. Each 6-piece set has two 4" wefts and four smaller 1.2" wefts, so you can tuck the small pieces close to your part and use the wider ones where you'd like more volume. The thin, seamless silicone wefts lie flat against your head and mimic natural hair growth for a flawless blend, even on the thinnest hair.
You can clip in and remove the fill-ins in minutes, which makes them easy to wear on the days you'd like a little extra fullness. They come in 12" (55g), 16" (85g) and 20" (100g).
Can Invisible Tape-In hair extensions cover thinning at the crown?
Yes, and they're the perfect option if you'd prefer coverage with nothing to wear or remove each day. Our Invisible Tape-In hair extensions are ideal for the crown of the head and all over. Each pre-taped skin weft is designed to mimic hair growing from the scalp, and the result is lightweight and virtually invisible as each weft lies flat.
For the crown only, we recommend one 25g pack of Invisible Tape-In hair extensions, and for a full look, you can pair it with at least 1 to 2 packs of Traditional Tape-In hair extensions.
Like all our semi-permanent hair extensions, they share three qualities:
- 100% Remy human hair sourced from donor hair with the cuticle intact and aligned for a longer lifespan
- No silicone coating. Just real, uncoated high-quality hair.
- Free from harsh chemicals and crafted with care
Installation usually takes about 30 minutes to an hour and a half, and we recommend having them applied by a licensed hair professional, who can confirm the right placement and number of packs at your appointment. Invisible Tape-In hair extensions can be reused up to four times, with move-ups every 6 to 9 weeks.
Which hair extensions suit hair that's thinning all over?
When thinning is all over rather than in one spot, a lighter set with more, narrower wefts distributes the weight evenly. Our Seamless Clip-In hair extensions have a thin, flexible silicone band that sits comfortably against the scalp without added bulk, which suits fine hair. If your hair is very fine, go lighter in grams for comfort, and our guide to hair extensions for fine and thin hair explains how to build up volume gradually.
For a semi-permanent option, our I-tip hair extensions are a great fit for even thin hair types. They're applied without heat or glue, which makes them gentle for a heat-sensitive scalp or fine hair.
A halo is a lovely way to add length and fullness for those with thin or stringy hair ends when there's enough hair on top to cover its fine wire, and our guide to how halo hair extensions work explains who it suits.

How many grams of hair extensions should you add to thinning hair?
A few grams of hair extensions go a long way on thinning hair, especially when they're placed exactly where you'd like more fullness. As a guide, Natural Volume is up to 125g for subtle, natural-looking fullness, Full Volume is 125g to 190g for noticeably fuller hair, and Extra Full Volume is 190g to 270g for maximum fullness. Our Invisible Clip-In hair extensions (45g to 55g) and Thinning Hair Fill-Ins (55g to 100g) both sit within Natural Volume.
For a full set of Classic Clip-In hair extensions on fine or thin hair, we recommend 18" 125g or 20" 160g. Our guide to how many clip-in hair extensions you need goes through each weight in more detail.
How do you wear hair extensions comfortably on thinning hair?
A few simple habits keep your own hair comfortable while you wear hair extensions:
- Spread the hair extension pieces across a slightly larger area than the spot you'd like to fill, and let the natural coverage do the work.
- Snap the clips in securely so they feel comfortable rather than tight, as the American Academy of Dermatology recommends.
- Remove clip-in hair extensions before sleeping.
- Brush gently from the ends up with a loop brush or wide-tooth comb.
- For tape-in hair extensions, book a move-up every 6 to 9 weeks to keep them comfortable and blending beautifully.
Thinning on top is very common, and the American Academy of Dermatology recommends seeing a dermatologist if you notice your part getting wider. Hair extensions can then add fullness exactly where you'd like it.
