What a hair treatment costs at a Seoul salon, from ₩50,000

A hair treatment at a Seoul salon — a conditioning service for the hair itself — starts at ₩50,000 for a quick rinse-out and runs past ₩500,000 for a full keratin smoothing, priced mainly by hair length and brand.

Seoul salons sell hair treatments under a few names — on millio's English menus you'll see treatment or care, and a translation app may say “clinic” — but it's one category: a conditioning service for the hair strands, separate from a cut, color, or a scalp-focused head spa.

Every figure below is from a real menu of a hair salon listed on millio, checked on 2026-11-04 across the 49 hair salons listed in Seoul that day — 40 of them had a treatment line confident enough to count, across 85 menu lines.

  1. 01A hair treatment on a Seoul salon menu runs ₩50,000 to ₩550,000Across the 40 of 49 Seoul hair salons listed on millio with a treatment line, prices start at ₩50,000 for a quick 40-minute conditioning rinse and run to ₩550,000 for a full keratin smoothing service on long hair. What moves the price is the kind of treatment, your hair length and the product brand — the lines below show each.
  2. 02“Treatment” and “care” on a menu mean the same lineSeoul salon menus use more than one word for this category — on millio you'll see treatment or care, and a translation app may render the Korean menu word as “clinic”. All of them mean a conditioning service for the hair, not a wash. If a line isn't labelled head spa or scalp, it's priced as a hair treatment.

  3. 03The cheapest line is a 40–45 minute rinse-out treatmentAt Sunsiki Hair Main Branch in Hongdae, an L'Oréal Absolut Repair rinse is ₩50,000 for 40 minutes, and a post-color treatment (L'Oréal Metal DX) is ₩60,000 for 45 minutes — the same salon's keratin smoothing costs five to eight times that. A brand name on the menu doesn't tell you the price; the specific line does.
  4. 04Most treatments run ₩80,000 to ₩275,00069 of the 85 treatment lines fall in this band — for example ₩80,000 at Park Jun Beauty Lab Myeongdong (60 minutes), ₩180,000 at Nouhaus in Hannam (60 minutes), and ₩275,000 at Bit&Boot in Gangnam, priced by which stylist does it.
  5. 05Keratin and protein smoothing is priced by hair lengthSunsiki Hair Main Branch's keratin treatment is ₩300,000 for short hair, ₩350,000 for medium, ₩400,000 for long — all booked for 180 minutes, three hours. Juno Hair Apgujeong Rodeo Branch 1 prices its keratin line at ₩380,000, rising to ₩440,000 for shoulder-length hair and ₩550,000 for waist-length. Confirm your length with the salon before booking — it changes the price.
  6. 06A salon's own tier names don't match another salon'sPark Jun Beauty Lab Myeongdong's branded Shiseido line is ₩140,000–180,000 (90–120 minutes) by hair length, below its own Cinderella line at ₩250,000–350,000 (120–180 minutes). Juno Hair Myeongdong 2nd prices its own three-tier system at ₩130,000 (basic), ₩170,000 (special), ₩200,000 (premium) over 60–90 minutes. Compare the price and minutes, not the tier name.
  7. 07The same salon can price one brand three times anotherHearts Dosan runs four branded treatment lines at the same 60 minutes: Milbon at ₩110,000, Aujua at ₩165,000, Shiseido at ₩220,000, and Venus at ₩330,000. With the time held equal, the brand name is what moves the price — worth asking which product line a quote is for.
  8. 08Book the treatment as its own line, not a chair add-onA hair treatment is usually its own appointment slot, not something added automatically onto a cut or color. Ask the salon to book it separately if you want one, and say your hair length up front if the menu prices by length — it's the number that changes the quote.

A Korean head spa is a staged scalp treatment — scalp check, scaling, deep cleanse, massage — that takes 40–90 minutes and costs ₩50,000–₩270,000 a session at Seoul hair salons on millio. It is not a hair-loss cure, and the stage count sets the price.
