Salon color care from a Cheongdam stylist — helps dyed color stay vivid and supports a thinning scalp, in one daily wash.
Nejoo is a color-longevity shampoo, not a dye. Built by Cheongdam hair stylist Park Ne-joo, it cleanses with an SLES/SLS-free surfactant blend so freshly colored hair holds its tone longer, while wild-soybean (Glycine Soja) germ extract — its Korea-registered anti-hair-loss-symptom active — and a ceramide/cholesterol lipid blend look after the scalp and cuticle.
- Color longevity — a gentle, low-stripping cleanser base helps dyed color fade more slowly.
- Anti-hair-loss-symptom active — Glycine Soja (wild soybean) germ extract, a Korean functional-cosmetic ingredient.
- Barrier care — ceramide NP, cholesterol and hydrogenated lecithin for scalp and strand.
- No PPD, ammonia, peroxide, silicone or parabens — Citrus Bouquet scent, 500ml.
How to use: Massage a suitable amount through wet scalp and hair, work into a light lather, then rinse thoroughly. For everyday use.
Read before you buy: This is a cosmetic color-care shampoo — it does not deposit or change hair color, and the "anti-hair-loss" claim is a Korean functional-cosmetic symptom-relief designation, not a medical hair-regrowth treatment. We list every ingredient and its risk level below so you can decide for yourself.

Why ours winsCredit where it's due — this sulfate-free, biotin-and-botanical formula actually screens a touch cleaner than ours. But it's a pure anti-thinning shampoo: no color-longevity role, no Korean functional certification, and it leans on tea-tree, rosemary, cedarwood and clary-sage oils. Different job; we stock ours for color-treated hair.

Why ours winsA seriously well-built scalp shampoo — biotin, adenosine, saw palmetto, niacinamide and ceramide NP. But it gets its scalp kick from zinc pyrithione, denatured alcohol and fragrance, and does nothing for color. Ours screens a step cleaner and is built to hold dyed color, not just treat the scalp.

What that benchmark led us to decide
Why we picked it
Holds dyed color without a dye's harshness
An SLES/SLS-free glucoside-and-betaine cleanser base strips less than a standard shampoo, so freshly colored hair fades more slowly — with no PPD, ammonia or peroxide anywhere in the formula.
Wild-soybean germ extract for scalp + thinning hair
Glycine Soja germ extract is its Korea-registered functional anti-hair-loss-symptom active, backed by ceramide NP, cholesterol and hydrogenated lecithin for barrier care.
No oxidative-dye chemistry at all
Unlike the color and grey shampoos it sits beside, there's no PPD, resorcinol, toluene-2,5-diamine or peroxide here — the only flags are one primary surfactant, denatured alcohol and fragrance allergens.
Worth knowing
It does not color or cover grey
This maintains existing color and tone; it won't deposit pigment or hide regrowth. If you want coverage, you need an actual dye.
Olefin-sulfonate primary surfactant + denatured alcohol
Sodium C14-16 Olefin Sulfonate is an effective but moderately stripping cleanser, and Alcohol Denat. sits mid-list — fine for most, worth noting for very dry or sensitive scalps.
Fragrance allergens (limonene, hexyl cinnamal)
The Citrus Bouquet scent declares fragrance plus limonene and hexyl cinnamal — common EU-listed allergens a fragrance-sensitive scalp may react to.
Our take
If you color your hair and want a daily shampoo that protects the result instead of scrubbing it out, this is an easy one to recommend — it screens 8.5, the cleanest on its shelf, and pairs gentle cleansing with a real scalp-and-strand care story from a 20-year Cheongdam stylist. Just buy it for what it is: color longevity and scalp care, not coverage. Every flagged ingredient is laid out below.
Honest note — this is a cosmetic color-care shampoo, not a hair dye and not a medical hair-loss treatment. The 'anti-hair-loss' claim is a Korean functional-cosmetic symptom-relief designation.
Cheongdam salon, in a bottle
Color that lasts, scalp that's looked after
Naeju isn't a dye — it's the daily wash that protects the dye you already paid for, built by a Cheongdam stylist who spent 20 years watching salon color wash down the drain too soon.
I wanted the shampoo my clients use at home to stop undoing the color we'd just perfected in the chair — gently, every single day.
Park Nae-ju · Cheongdam hair stylist, 20 yrs
01
Color longevity
An SLES/SLS-free surfactant blend cleanses without aggressively stripping, so freshly colored or permed hair holds its tone and shape for longer between salon visits.
02
Scalp & thinning-hair care
Registered in Korea as a functional anti-hair-loss-symptom shampoo, with wild-soybean germ extract as the active for a scalp under daily styling stress.
03
Barrier repair
Ceramide NP, cholesterol and hydrogenated lecithin — the skin-barrier lipid trio — help the cuticle hold moisture so strands feel smoother, not squeaky.
Hero · Functional active
Wild soybean (Glycine Soja) germ extract
The germ of the wild soybean is rich in isoflavones and amino acids. It's the registered functional ingredient behind Naeju's anti-hair-loss-symptom claim — a cosmetic scalp-support designation, not a medical regrowth drug — and the reason the formula reads as care, not just cleansing.
01 · The scent
Citrus Bouquet
A bright, clean citrus-floral that lifts off the scalp in the shower and settles into a soft, fresh finish — the salon-fresh smell without anything heavy.

How to use
1
Wet & lather
Massage a suitable amount through wet scalp and hair until it works into a light, even lather.
2
Let it work
Take a minute to work it over the scalp — this is the part that looks after the roots, not just the lengths.
3
Rinse clean
Rinse thoroughly with lukewarm water. Suitable for everyday use, color-treated and permed hair.
Honest note — This is a cosmetic color-care shampoo. It does not deposit or change hair color, and the anti-hair-loss claim is a Korean functional-cosmetic symptom-relief designation, not a medical hair-regrowth treatment.
