Eylure's DYBROW has been a staple in UK bathroom cabinets for years. At £6.40 for up to 12 applications, it promises salon-style brow tinting at home in under 15 minutes. The numbers back up its popularity: over 56,000 ratings, a 4.4-star average, Amazon's Choice badge, and a firm grip on the #1 spot in Eyebrow Colours. Over 10,000 units sold in the past month alone.

But dig into recent reviews and a different picture emerges. While roughly half of buyers are thrilled, a striking 30% left one-star ratings. The complaint is almost always the same: the dye simply didn't develop any colour at all. That's not a minor quibble, and it's a pattern too consistent to ignore.

So is DYBROW still the reliable at-home brow dye it once was, or has something changed? We went through 80 recent reviews to find out.

What You Get in the Box

The DYBROW kit comes with a dye cream tube, an activator solution tube, a mixing dish, an applicator stick, and instructions. The Dark Brown shade is one of five variants (Black, Light Brown, Mid Brown, and a Dark Brown Twin Pack round out the range). Eylure markets it as cruelty free, vegan, and paraben free.

Application is straightforward. You squeeze equal amounts from both tubes, mix them together, brush the mixture onto your brows, wait 10 to 15 minutes, and wipe off. Several reviewers noted you only need a tiny amount per use, which is why some have stretched a single kit across a couple of years rather than the advertised 12 applications.

One practical tip from the reviews: apply a thin layer of petroleum jelly around your brows before dyeing. Multiple users mentioned this prevents any staining on the surrounding skin, though most agreed the formula doesn't stain much regardless.

When It Works, It Really Works

For the majority of buyers, DYBROW delivers exactly what it promises. Around 51% left five-star reviews, and the praise is consistent: easy to use, good colour payoff, and a genuine money saver compared to salon visits at £15 to £30 a pop.

Long-term users are especially vocal in their support. Several reviewers have repurchased the kit for years, calling it the best eyebrow dye they've tried. One user reported using the same tube for two years by squeezing small amounts, using it not just on brows but also on sparse lashes and stray grey hairs at the temples.

Grey coverage is a particular strength. Users with greying brows reported solid results, though a few found the Dark Brown shade too subtle for stubborn greys and recommended stepping up to Black instead. The colour itself was described as natural-looking and buildable, meaning you can control the intensity by adjusting how long you leave it on.

The "no skin staining" point came up repeatedly. Unlike some salon tints that leave you with brown patches around your brows for a day or two, DYBROW wipes cleanly off the skin while holding onto the brow hairs. For anyone who's ever walked out of a salon looking like they drew their eyebrows on with a marker, that matters.

The 30% Problem: When It Doesn't Work at All

Here's where things get uncomfortable for Eylure. Nearly 30% of recent reviewers gave the product one star, and the feedback isn't about shade preference or minor gripes. The overwhelming complaint is that the dye produces zero colour development. Nothing. Not faint, not wrong shade, just no visible change whatsoever.

This isn't a handful of first-timers making mistakes. Several of these one-star reviewers explicitly mention being experienced with brow tinting, having used DYBROW successfully in the past, or being familiar with other brands. One user tried three separate applications from the same kit with no result. Another left the mixture on for 40 minutes (well beyond the recommended time) and still saw no change.

A recurring theme in the negative reviews is that the formula seems to have changed. Multiple buyers noted that previous purchases worked perfectly but recent ones didn't develop colour at all. One five-star reviewer who otherwise loves the product mentioned noticing a formula change in the past year. A three-star reviewer with six helpful votes wrote simply: "I first bought this a couple of years ago and was really impressed with the colour and how long it lasted. Not this time."

There are also scattered reports of missing components (no spoolie brush included) and at least one reviewer who suspected they received a counterfeit product because both tubes appeared to contain the same cream-coloured substance with no pigment difference.

The pattern strongly suggests a quality control or batch consistency issue rather than user error. When experienced users who previously got good results suddenly get nothing, and when the complaint appears this frequently, it points to something in the manufacturing or supply chain.

How Long Does It Actually Last?

Eylure claims up to six weeks of colour. The reality, based on recent reviews, is more like two to four weeks for most users, with some reporting as little as one to two weeks before noticeable fading. One reviewer specifically noted "2-3 weeks tops" for the Dark Brown shade.

Several users found that the colour fades noticeably after the first shower or face wash. This seems to be more of an issue with the lighter shades. A couple of reviewers who tried both Dark Brown and Black said the Black shade had significantly better staying power, and one recommended Black specifically for anyone trying to cover grey.

For context, two to three weeks of colour from a £6.40 kit that gives you multiple applications is still solid value compared to salon pricing. But if you're buying this specifically because the box says six weeks, temper your expectations.

Who This Works Best For (and Who Should Be Cautious)

Based on the review patterns, DYBROW seems to perform best for users who already have some natural brow colour and want to deepen or enrich it. Users with medium to dark hair who want fuller-looking brows consistently report good results. The product also works well as a maintenance tool between salon appointments.

The results are far less reliable for users with very light or blonde brows. This is the group most represented in the negative reviews. While some blonde users report success (one went from invisible brows to visible ones and was thrilled), others saw no colour development at all despite extended application times. If you have very fair brows, be aware this is a gamble.

Grey coverage falls somewhere in the middle. It works for many users, but stubborn or fully grey brows may need the Black shade rather than Dark Brown to get proper coverage.

The Verdict: 3.5 out of 5

This is a tricky product to rate because the experience is so split. When DYBROW works, it's genuinely excellent: affordable, easy to use, good colour, minimal mess, and far cheaper than regular salon visits. The loyal customer base that has repurchased for years isn't wrong about any of that.

But you can't overlook a 30% one-star rate. That's not normal product dissatisfaction. The consistency of the "zero colour development" complaint, especially from previously satisfied customers, points to a real quality control issue that Eylure needs to address. Buying this kit right now feels like a coin flip for some users, and that's not where a #1 best seller should be.

If you've used DYBROW before and it worked for you, it's probably still your best bet at this price point. If you're trying it for the first time, especially with light or blonde brows, buy it knowing that you might need to return it. Keep the packaging and receipt.

At £6.40 (or £5.44 with Subscribe and Save), the financial risk is low. But the frustration of a product that literally does nothing isn't something a low price tag makes up for.
