Brow lamination
Chemical brow perming · 'fluffy brows'
The brushed-up 'fluffy brow' of the late 2010s became a salon staple and then an at-home kit, and is now the subject of 'is the laminated brow over?' pieces as thinning and breakage stories accumulate.

Does Brow lamination work?
Trend. A trend with real chemistry behind it. A perm is a perm, and the brow has far fewer hairs to spare than the head. There are no clinical trials of brow lamination.
- Verdict
- Trend Popular for reasons that are mostly social. Harmless at best; manage expectations.
- Evidence base
- 2 PubMed-indexed studies cited below (review); no systematic review or randomised trial on the claim itself.
- Suits
- Unruly, downward-growing or asymmetric brows with healthy hair and skin, treated no more often than every six to eight weeks by a trained technician.
- Not for
- Sparse or fine brows, eczema or psoriasis around the eyes, recent retinoid use on the brow, pregnancy by convention, or anyone with a history of perm or hair-dye allergy.

What it is
A perm for the eyebrows. A thioglycolate-based solution softens the disulphide bonds in the hair, the brows are brushed into an upright, fanned shape, and a neutralising solution resets the bonds so they hold the new direction for four to eight weeks. A tint and a nourishing oil are usually added.
How it works
The chemistry is that of a hair perm applied millimetres from the eye: ammonium thioglycolate breaks the keratin cross-links and hydrogen peroxide or a bromate re-forms them. Each cycle weakens the hair a little, so repeated treatments at short intervals leave brows brittle and sparse. Timing, concentration and the skin barrier of the brow decide whether the result is glossy or frizzed and inflamed.
What the evidence says
There are no clinical trials of brow lamination. A 2025 review of thioglycolate compounds in brow lamination, the first to address the technique, describes allergic contact dermatitis, hair-shaft damage and pigment change, notes transdermal absorption of the compounds, and calls for regulation of concentrations. The wider literature on perm chemistry documents contact allergy to thioglycolates in hairdressers and clients. The risk is cumulative and cosmetic, not systemic in normal use.

What the studies show
- review
The first review of brow lamination chemistry describes allergic contact dermatitis, structural and pigment changes in brow hair and transdermal absorption of thioglycolates, and calls for regulation of concentrations.
Effects of Thioglycolate Compounds in an Emerging Technique in the World of Cosmetics-Brow Lamination. — J Cosmet Dermatol, 2025. PMID 39469969.
- review
A review of the adverse reactions to cosmetic procedures around the brow and eye, relevant because lamination is often combined with tint and semi-permanent pigment.

Studies are selected for relevance and quality, not for agreement with the verdict; PubMed records are linked so the reader can check them.
Who it suits
Suits
Unruly, downward-growing or asymmetric brows with healthy hair and skin, treated no more often than every six to eight weeks by a trained technician.
Not for
Sparse or fine brows, eczema or psoriasis around the eyes, recent retinoid use on the brow, pregnancy by convention, or anyone with a history of perm or hair-dye allergy.
Alternatives
The two reviewed treatments most often weighed against Brow lamination, on the same standard.
| Brow lamination | Microblading and nano brows | |
|---|---|---|
| Verdict | Trend | Established |
| What it is | A perm for the eyebrows. | Cosmetic tattooing of the eyebrows. |
| Evidence base | 2 PubMed-indexed studies cited below (review); no systematic review or randomised trial on the claim itself. | 4 PubMed-indexed studies cited below (case series, review); no systematic review or randomised trial on the claim itself. |
| Suits | Unruly, downward-growing or asymmetric brows with healthy hair and skin, treated no more often than every six to eight weeks by a trained technician. | Sparse or asymmetric brows in someone with normal, not very oily, skin who wants low-maintenance definition for a year or two and chooses a conservative, natural shape with a well-trained artist. |
| In one line | A trend with real chemistry behind it. A perm is a perm, and the brow has far fewer hairs to spare than the head. | The strokes are honest for a year; after that you are managing a fading tattoo, which is why the restrained version is the one to choose. |
Risks
Contact dermatitis, hair breakage and thinning with repeated use, chemical irritation of the eye if solution runs, and frizz from over-processing.
In Singapore
A beauty-salon service in Singapore with no medical regulation; the products are cosmetics. Patch testing before the first treatment is sensible and rarely offered.
