Why does some Korean shampoo smell like herbal medicine?

Walk into a Korean drugstore and head to the shampoo aisle, and it can feel less like a hair aisle and more like a pharmacy. Bottles promise scalp care, hair loss symptom relief and low-pH formulas, and some smell more like herbal tea than shampoo. That herbal scent isn’t random: Koreans have been washing their hair with plants since the Joseon era, long before modern shampoo arrived.

Korean shampoo is sorted mainly by function and scalp type, and the two most distinctive kinds are hair-loss symptom relief shampoos and herbal “hanbang” shampoos. If you’re shopping in Korea, you’ll also see scalp care, mildly acidic, damage repair, volume, perfume and solid shampoo bar types. This guide explains each type in plain English and picks a few representative products so you know what to look for on the shelf.

Korean hair loss shampoo: what it is (and isn’t)

Many bottles in Korea are labeled “탈모증상완화” (hair loss symptom relief). This is a functional cosmetic category. Since 2017, these products have been classed as functional cosmetics, not quasi-drugs, and they need to contain approved functional ingredients such as dexpanthenol, biotin or zinc pyrithione in the required amounts.

There are also rules about what brands can say. Korea’s food and drug regulator does not allow shampoos to claim they treat, prevent or regrow hair, so you’ll see wording like “hair loss symptom relief” instead. A shampoo can support a healthy scalp, but it isn’t a hair loss treatment. If you’re worried about hair loss, a dermatologist is the right person to ask.

Representative products

  • Labo-H Scalp Strengthening Shampoo (hair loss symptom relief): A long-time Olive Young shampoo best-seller. It’s built around probiotics-derived ingredients plus ceramide, PDRN, biotin and caffeine. A 400ml bottle runs around ₩24,000, and the large 750ml set is often discounted. Some shoppers say it doesn’t foam much and needs two washes.
  • Dr.FORHAIR Polygen Thickening Shampoo: Aimed at fine, thinning hair and flat roots, and very popular among Olive Young shoppers. Sets start from around ₩29,900 during promotions. The scent leans herbal, so it’s a love-it-or-hate-it for some.

Korean herbal (hanbang) shampoo

“Hanbang” means traditional Korean herbal medicine. Hanbang shampoos use herbal ingredients such as ginseng and are especially popular with middle-aged and older shoppers. Well-known names include Ryo (from Amorepacific), Daeng Gi Meo Ri and Lien.

Where Korean herbal shampoo comes from

Herbal hair washing is an old Korean habit. During the Joseon era, people washed their hair with water boiled with sweet flag (changpo) on the Dano festival, and rice water and plant juice were also used instead of harsh lye. Modern shampoo came much later, and Korea’s first domestic shampoo launched in 1967. Around the same time, Korean beauty companies were building their herbal (hanbang) tradition: Amorepacific’s ginseng cream from 1966 is considered Korea’s first hanbang cosmetic. Today’s hanbang shampoos draw on that herbal heritage, though every brand’s formula is different.

Representative herbal shampoos

  • Ryo Jayang Yunmo: A long-running herbal line from Ryo. Some reviewers say it doesn’t have a heavy medicinal smell.
  • Daeng Gi Meo Ri Gi Gold Premium: Described as containing more than 33% traditional herbal extract, with ingredients such as ginseng. Reviews are split on the scent: some love the mild herbal fragrance, others find it too sharp.

Herbal ingredients and formulas vary a lot between brands, so don’t judge by the word “herbal” alone. Check the full ingredient list, and sniff-test if you can.

Scalp care shampoos

Scalp care is one of the biggest shampoo categories in Korea, and many products pair a scalp concern with a texture or feeling. You’ll see three common styles:

  • Mildly acidic: Formulated closer to the scalp’s natural, slightly acidic pH. Often chosen for sensitive, itchy or flaky scalps. Dr. Nobid’s mildly acidic shampoo is a popular example.
  • Cooling and oil control: Fresh-feeling shampoos with tea tree or mint for greasy roots. Aromatica Tea Tree Purifying Shampoo is a highly rated option for oily scalps.
  • Scaling (exfoliating): Shampoos or scrubs that help remove buildup and dead skin from the scalp. Use them occasionally, not every day.

Other popular types

  • Shampoo bars: Solid bars are light and easy to pack. Ton28 Shampoo Bar S21 Black Bean (about ₩11,000 for 100g) is one to look for.
  • Damage and protein care: For bleached, permed or dry hair.
  • Volume, color care and perfume: Pick by hair type or by scent.

FAQ

Do Korean hair loss shampoos really work?

They’re designed to relieve hair loss symptoms and support a healthy scalp, not to treat hair loss. Results vary from person to person, so see a dermatologist if you’re concerned.

Is herbal shampoo good for hair loss?

Hanbang shampoos use traditional herbal ingredients and suit people who like that style of care. Formulas differ a lot, so check the ingredient list instead of relying on the label.

What is a mildly acidic shampoo?

It’s a shampoo formulated closer to the scalp’s natural, slightly acidic pH. Many people with sensitive, itchy or flaky scalps choose this type.

Which Korean shampoo is best for an oily scalp?

Look for cooling, tea tree or oil-control scalp shampoos, such as Aromatica Tea Tree Purifying Shampoo.

Where can tourists buy Korean shampoo?

Olive Young is the easiest choice, and large supermarkets and online shops are good for herbal brands. Tourists can usually claim a tax refund with a passport.
