Brow lamination lasts four to six weeks as a rule, stretching to around eight weeks if you look after it well. That window comes straight from the brow hair growth cycle. Unlike a perm on scalp hair, which holds until you cut it out, brow hairs are constantly shedding and regrowing on their own individual timetables. As each treated hair falls out and a fresh, untreated one grows in behind it, the laminated set loosens gradually rather than dropping off all at once. Brow lamination runs at all three Skin & Beauty Box branches (Clifton Down, Westbury on Trym and Westbury Park), so it doesn't matter which one is closest to you.

Why brow lamination fades gradually, not all at once
Every brow hair sits somewhere on its own growth cycle: an active growing phase, a resting phase, then shedding. At any given time your brows are a mix of hairs at different stages, not a uniform batch that all arrived and will all leave together. Brow lamination works by breaking down the bonds in each hair, repositioning it, then resetting those bonds so it holds the new shape. That reset only affects the hair itself, not the follicle underneath.
So when a treated hair reaches the end of its cycle and sheds, it's replaced by a hair that was never laminated. It grows in pointing wherever it naturally grows, not where the lamination set it. A few of those coming through is barely noticeable. Enough of them, and the overall shape softens back towards how your brows sat before, which is what most people mean when they say lamination has "worn off". Nothing failed. The hair simply did what hair does.
What shortens how long your lamination lasts
A few things speed up that fade:
| Factor | Why it matters |
|---|---|
| Oil-based cleansers and balms | Oil breaks down the bonds the lamination solution set, loosening the shape early |
| Heavy exfoliants around the brow (retinol, AHAs) | These strip and turn over skin faster, taking the set with them |
| Getting brows wet in the first 24 hours | The set is still stabilising. Water, steam or sweat before it's fully settled can undo the shape |
| Sleeping face down | Not confirmed by any study, but plausible: repeated rubbing against a pillow could flatten and disrupt the set faster than it would fade on its own |
None of these will ruin the treatment outright. They just eat into the top end of that four-to-six-week window rather than letting you get anywhere near eight.
What are the downsides of brow lamination?
Brow lamination is a good treatment for the right brow, but it isn't right for every brow, and it isn't without limits.
Fine or previously chemically treated hair (bleached, over-plucked, already laminated recently) is the main risk area. It can over-process, leaving hair feeling dry, brittle or thinner-looking rather than fuller. That's why salons leave a gap between sessions: don't book another lamination sooner than about six weeks after the last one, even if the set has started to soften. The hair needs that time to recover before it goes through the process again.
The other honest limit: lamination repositions the hair you already have. It doesn't add any. If your brows are genuinely sparse rather than just unruly or flat, lamination will tidy what's there but it won't fill a gap where there's no hair growing at all. For that, a treatment built around shaping and filling, like HD Brows below, does more of the work.
As with any tint-adjacent treatment, a patch test is needed up to 48 hours before your appointment. For current prices, see price list.
Is brow lamination really worth it?
For the brow type it's built for (unruly, flat, downward-growing, or just tired of daily brushing and setting spray) it's genuinely worth it. Four to six weeks of low-maintenance shape from a single appointment is a fair trade for most people who fall into that category.
Where it's a weaker fit is sparse or gappy brows, where the honest answer is that a shaping treatment will do more for you than a repositioning one. That's not a reason to avoid lamination. It's a reason to be clear about which problem you're solving before you book.

Brow lamination vs HD Brows: what is the difference?
These get compared constantly, and the confusion is understandable because both are brow treatments that leave you looking noticeably tidier. They solve different problems though.
Brow lamination is a two-step chemical process. The first solution breaks down the bonds in the hair, the second rebuilds them once the hair is repositioned. It uses only the hair you already have and redirects it into a fuller, more uniform shape. Nothing is added, nothing is removed. It's the answer for hair that grows the wrong direction, lies flat, or needs brushing into place every morning.
HD Brows is a seven-step treatment: a proper consultation about face shape and skin tone, custom-blended tint, brow mapping, then hair removal using whatever combination of waxing, threading, tweezing and trimming the shape actually needs. It finishes with the brows filled in using the HD Brows makeup range, plus a quick lesson so you can recreate the look yourself. It's a shaping and definition treatment, not a repositioning one, and it's particularly good for over-plucked or asymmetric brows because the mapping step works out where hair should be encouraged back rather than just tidying what's left.
Skin & Beauty Box runs HD Brows in-house, so this isn't a comparison built from someone else's marketing. If your brows are unruly or grow downwards, lamination is the better first move. If they're sparse, over-plucked or uneven, HD Brows does more. And they're not mutually exclusive: a lot of clients get HD Brows for shape and lamination for direction, in the same appointment or close together. See brow lamination and HD Brows for what each one covers.
FAQ
How long does eyebrow lamination last? Eyebrow lamination and brow lamination are the same treatment. It lasts four to six weeks typically, up to eight weeks with good aftercare, for the same reason: the brow hair growth cycle gradually replaces treated hairs with untreated ones.
What should I avoid after HD Brows? Because HD Brows includes a tint, avoid water, steam, sweat and makeup on the brow area for the first 24 hours while the tint sets. Skip saunas, swimming and heavy sun exposure over that same window, and avoid oil-based cleansers on the brows until the colour has properly taken.
What is the difference between HD Brows and laminated brows? Laminated brows use only the hair you've already got, reset into a smoother, more uniform shape for four to six weeks. HD Brows adds shaping, tinting and filling on top of that, so it can create definition even where the hair itself is sparse. If your brows just need taming, lamination does it. If they need building, HD Brows does more.
