Honest Lab True Lab Scalp Hair Vinegar 210ml

The Gist

Honest Lab True Lab Scalp Hair Vinegar 210ml is a lightweight rinse treatment marketed to reduce scalp oil and odor. It delivers an immediate cooling, tingling sensation on the scalp and is dispensed via a pointed nozzle for targeted application. The formula contains salicylic acid and menthol alongside vinegar, though the finished scent is subtle and powder-like rather than traditionally sour.

What Korean reviewers say

Daiso shoppers rate it 4.8/5 across 1,899 reviews, signaling consistent satisfaction among budget-conscious buyers. Detailed written feedback reveals meaningful trade-offs: many users report genuine oil control and reduced scalp odor, particularly over extended wear, but multiple reviewers flag stubborn rinsing residue that leaves hair feeling sticky or clumpy immediately after use. Hair texture improves in smoothness and frizz reduction for some, though others report stiffness or dryness that necessitates follow-up conditioner. The cooling sensation is the defining feature, though intensity varies; a few users note the menthol can sting if it contacts eyes, prompting safer application methods like foam-bottle transfer.

Bottom line

At $3.70, this is a worthwhile trial for oily scalp types seeking affordable scalp treatment, but the rinsing difficulty and dryness risk make it less versatile for fine, dry, or normal-scalp hair. Best as a targeted scalp rinse for greasy hair, paired with conditioning to offset texture trade-offs.
