Dr. Groot Scalp Soothing Shampoo is a K-beauty scalp-care shampoo from LG H&H (LG Beauty) built around biotin, Centella (cica) extract, and prebiotics — a formula that skips parabens, silicones, sulfates, and gluten. After researching buyer feedback and the brand’s claims, my take is this: it is a genuinely pleasant, dermatologically tested daily shampoo that many buyers say leaves their scalp feeling cooler, cleaner, and less oily over time — but the headline “clinically proven” oil-reduction claim rests on the brand’s own small 22-subject test, and no cosmetic shampoo can regrow hair the way drug treatments such as minoxidil can.
In this 2026 review, I unpack what is actually in the 385ml bottle, what buyers praise and complain about, the red flags in the marketing that deserve your skepticism, and who this shampoo is actually good for.

Product Overview
Dr. Groot is LG H&H’s scalp-focused hair care line, and this Scalp Soothing Shampoo is its biotin-and-cica cleanser: biotin for the hair-strength story, Centella asiatica (cica) extract for its soothing reputation in K-beauty, and prebiotics aimed at supporting a balanced scalp environment. The formula deliberately leaves out parabens, silicones, sulfates, and gluten, and it is dermatologically tested for all scalp types.
The brand makes three big claims. First, that the shampoo is “clinically proven” to reduce excess scalp oil by 93% after one use — a claim the brand attributes to its own 22-subject test, which is marketing, not independent science (more on that below). Second, that Dr. Groot is the “#1 Korean hair care brand for hair thickening,” citing Nielsen 2023 data — a brand-cited ranking, not an independent finding. Third, that it visibly volumizes thin, damaged, and dry hair — a cosmetic volumizing claim, which is very different from regrowing hair.
In practice, buyer feedback describes a cooling, refreshing wash with a light lather (expected without sulfates), hair that feels cleaner, lighter, and somewhat fuller, and — for many — a scalp that stays less oily between washes. It reads as a well-executed gentle daily shampoo with a scalp-care angle, rather than a treatment product.
What Buyers Like
- Cooling, refreshing scalp feel. The signature sensation — buyers consistently mention the fresh, tingly clean feeling during and after washing.
- Less oily scalp over time. Many buyers report their scalp stays fresher longer between washes with continued use.
- Hair feels cleaner, lighter, fuller. The silicone-free formula leaves hair feeling light rather than coated, with a bit of visible body.
- Gentle for frequent use. The sulfate-free, dermatologically tested formula suits people who wash daily or have sensitive scalps.
What Buyers Complain About
- Low lather. Sulfate-free means less foam — buyers used to rich lather need an adjustment period and sometimes a second wash.
- Premium price. Around $33 seen at major retailers (an observed figure, not a live price) — steep next to drugstore shampoos.
- Results vary. Not everyone sees the oil-control or volumizing effects; hair type and expectations shape satisfaction.
Red Flags to Consider
- “Clinically proven” rests on the brand’s own small test. The 93% oil-reduction claim comes from a 22-subject brand test — that is marketing dressed as science, not independent evidence. Treat it accordingly.
- A cosmetic shampoo cannot regrow hair. Volumizing and thickening-feel claims are cosmetic. Nothing in a shampoo bottle regrows hair the way drug treatments like minoxidil do — if a listing implies otherwise, that is a red flag.
- Not FDA-evaluated for treating hair loss. This is a cosmetic product, not a hair-loss treatment. For medical hair loss, consult a dermatologist rather than shopping for shampoos.
Frequently Asked Questions
Does Dr. Groot shampoo regrow hair?
No. Dr. Groot is a cosmetic shampoo — it can make hair feel cleaner, lighter, and look fuller, but no shampoo regrows hair. Hair regrowth is the domain of drug treatments like minoxidil. If you are experiencing medical hair loss, consult a dermatologist.
Is Dr. Groot shampoo sulfate-free?
Yes. The formula contains no sulfates — and no parabens, silicones, or gluten either. Expect a lighter lather than sulfate shampoos; that is normal. Most buyers adjust within a week or two, and some do a quick second wash.
How does Dr. Groot shampoo feel?
Buyers describe a cooling, refreshing sensation on the scalp during washing, with hair that feels clean, light, and slightly more voluminous afterward. The silicone-free formula avoids the coated feeling some shampoos leave behind.
Is Dr. Groot good for oily scalp?
Many buyers with oily scalps report their hair stays fresher longer between washes. The brand’s “93% oil reduction” figure comes from its own 22-subject test, so treat the number as marketing — but the broader pattern of buyer feedback on oil control is genuinely positive. It is dermatologically tested for all scalp types.
Final Verdict
Dr. Groot Scalp Soothing Shampoo is a well-formulated, pleasant K-beauty daily shampoo that earns its keep on scalp feel, gentleness, and oil control — not on the overblown marketing around it. Buy it for the cooling clean, the sulfate-free gentleness, and the lighter, fresher hair days. Do not buy it expecting regrown hair or clinically proven miracles: the 93% figure is a 22-person brand test, and real hair loss belongs in a dermatologist’s office. At its premium price (around $33 seen at major retailers — observed, not live), it is a treat-yourself staple for oily or sensitive scalps, not a medical solution.
