PPD, off the list

New · Levero Coloring Shampoo 300ml

PPD is off the list.
9,850 reviews say it still covers.

The most common reason people tell us they will not try a colour shampoo is one ingredient. Levero took it out — and it is Korea's most-reviewed product of its kind, with 9,850 customer reviews behind it. Here is how it sits next to the GDS shampoo we already sell.

Levero Coloring Shampoo in Black, Dark Brown and Light Brown

Why we brought it in

Korea reviewed it 9,850 times before we did.

9,850customer reviews across Naver Smartstore and the maker's own store — 5,231 and 4,619
4.7average rating across that set
99.42%grey coverage, measured by Ace Skin Clinical Research Institute, 20 Jan – 3 Feb 2026

We read the reviews before we stocked it. The strongest signal is that it behaves like a proper colour rather than a tinting shampoo — it covers, and it holds. Colour retained after five washes measured 85.48% in the same clinical set.

Both are permanent oxidative dyes delivered through a shampoo base, both build over two or three washes, and both are $29.99. The difference that matters is the dye molecule at the top of the list.

Which one is for you

Two honest answers, not one.

You want PPD off the label

You have read about it, you would rather not have it on your scalp, and you want grey covered properly. Levero is the straightforward answer — the removal is real, it is printed on the pack, and phenacetin went with it.

You have actually reacted to a hair dye

Then read this bit twice. Toluene-2,5-diamine took PPD's place, and people allergic to one very often react to the other. PPD-free is not allergy-free. Patch test 48 hours before every use, and if you have reacted before, treat this like any other oxidative colour.

The rest of what we would tell a friend: the pack says five minutes and reviewers report ten to twenty for full cover. It stains hands, hairline and tiles like any dye — the gloves are in the box for a reason. Apply to dry or towel-dried hair, not soaking wet. Expect the colour to build over two or three washes rather than land in one. And it tends to come out a shade deeper than the name suggests, so if you are between shades, size down.

Screened · Scored · Published

Review figures are analysed from 9,850 Korean-language customer reviews collected on Naver Smartstore and the maker's own store, translated and aggregated by us — they show relative weight rather than exact totals. Clinical figures are the maker's, measured by Ace Skin Clinical Research Institute against the maker's own baseline product. Screening scores are our own ingredient-by-ingredient assessment and describe a formula's ingredient profile, not how well it will work for you. Not for eyebrows or lashes. Patch test 48 hours before every use.
