Is this your first visit?

We recommend arriving without washing your hair so we can assess its usual scalp and hair condition more accurately and avoid repeated shampooing within a short period.

• Only one small or mid-size vehicle may parallel park by the shop's glass frontage.
• To avoid obstructing the garage access of the building to the left of YOONSI, park as far uphill as possible.
• Large vehicles may not be able to park if they are too wide.
• The road in front of the shop is one-way uphill.
• Do not use the resident-priority spaces across the street. Select the vehicle and parking option when booking.

Because we may be serving the previous guest or preparing for the next appointment, early entry is not available. Please arrive at your booked time. If you arrive early, take a short walk nearby or wait at a café.

Yes. Guests of any age or gender are welcome.

Except when two guests have consecutive appointments, accompanying visitors cannot wait inside the shop. YOONSI is a small, one-person studio, and even quiet noise can interrupt rest and immersion. Thank you for understanding; accompanying visitors are welcome to wait at a nearby café.

You may bring a pet if you let us know before booking. The shop does not provide pet pads, water bowls, or other pet supplies, so please bring everything your pet needs. Dogs prone to accidents must wear a diaper. Please also understand that barking in response to unfamiliar surroundings or sounds may disturb another guest's rest.

A ₩30,000 deposit per person is required for general bookings and bookings with service or class gift certificates. Membership guests do not pay a separate deposit.

Please pay the deposit within two hours of requesting a reservation. If payment is not confirmed, the request is automatically cancelled and you will need to book again.

Changes or cancellations are accepted until 17:00 the day before a weekday reservation, or until 17:00 two days before a weekend or public-holiday reservation. After that deadline, ₩30,000 is deducted from the deposit or Membership balance.

For consecutive changes or cancellations, ₩30,000 is deducted from the second occurrence onward, even when the request is made before the deadline.

For same-day cancellations or no-shows, the ₩30,000 deposit is deducted for general bookings and bookings with service or class gift certificates. For Membership bookings, the full price of the booked program or the session is deducted. The deposit and Membership balance are not both charged for the same reason, and no additional ₩30,000 is deducted for a same-day cancellation or no-show.

Read the full operating policy

YOONSI is a one-person studio, so two guests cannot receive services at the same time. To visit on the same day, please make two consecutive NAVER Booking reservations, one for each guest.

Please let us know when booking that you will use a gift certificate.

• If you are using a physical gift certificate, please bring it with you.
• Mobile gift certificates can be used after we check the serial number in the text message.
• For earlier gift certificates issued without a physical card, we check the issue record before use.

A ₩30,000 deposit is required for bookings with service or class gift certificates. For a one-time service, the deposit is returned in full after normal use and collection of the physical certificate or confirmation that it has been used. For a multi-session class, the deposit is returned in full after you attend and complete the booked lesson.

If you are using a gifted Membership, Membership booking rules apply and no separate deposit is required.

Membership & gift certificates

Calls are often difficult to answer during a service. You can contact us by SMS at our official number, LINE, KakaoTalk Channel, Instagram DM at @yoonsinatural, or NAVER TalkTalk. No channel is prioritized; we check and respond in turn during business days and operating hours.

Hair-length surcharges apply as follows:

• Around the shoulder blades: ₩20,000
• Around chest length: ₩30,000
• Waist length: ₩40,000

Hair extending below the waist toward the hips may be too long for us to provide the service.

Dry Head Spa involves no shampoo, so it has no hair-length surcharge or length limit.

If you have concerns about using aromatherapy, please ask for a consultation before booking.

We first provide general information about ingredients and scents. If we need to check personal health information, such as allergies, we first obtain separate consent and then ask only for the minimum information needed for a safe service.

After this check, we may omit the aroma or use a different scent. If needed, the service can proceed without aromatherapy.

Yes, you can.

We discuss preferences and lifestyle only as much as you wish, and keep conversation to a minimum if you would prefer a quiet rest.

We provide general safety guidance to every guest. If we need to check personal health information, such as allergies, pregnancy, how you feel that day, whether you can remain lying down, or the condition of the treatment area, we first obtain separate consent and then ask only for the minimum information needed. Before consent, we do not ask for specific health information or use it to make decisions about an individual guest.

For your safety and comfort, we may limit a service or recommend rescheduling in the following situations:

• You cannot remain comfortably on your back or have difficulty breathing in that position
• You are in late pregnancy or near your due date
• You have a fever, a potentially contagious illness, or feel significantly unwell
• You have consumed alcohol
• The treatment area has inflammation, infection, bleeding, or an open wound
• You received surgery, laser treatment, a skin procedure, an injection, or other medical treatment that day
• You have an allergy to aroma or cosmetic ingredients
• For Head Spa other than Dry Head Spa, or for Facial Spa, your hair extends below the waist toward the hips
• You are recovering or receiving treatment and a medical professional has advised rest

You may ask for general safety guidance, a schedule change, or alternatives before booking. If we need to check personal health information, we first obtain separate consent and then ask only for the minimum information needed. Please do not include specific health information in booking notes or similar messages before giving consent.

YOONSI does not provide services in a side-lying position.

We accept cards, cash, bank transfers, ZeroPay, SeoulPay, Apple Pay, NAVER QR payments, and Toss FacePay. Checks, foreign currency, and Kakao Pay are not currently accepted.

YOONSI uses a link sent by email instead of a password. For security, each link can be used only once within 15 minutes, and only the most recently issued link is valid. If you cannot find the email, check your spam folder first. You can request another email after one minute, or sign in with Google, NAVER, or Kakao.

You can close your account at any time from the account information screen in My Page. Personal information such as your email address and nickname is deleted immediately. If an unused gift certificate or Membership balance remains, closure is temporarily held to protect your rights. Please contact the shop to settle the remaining balance, and closure can then proceed immediately.

We are briefly checking the system to provide a safer service. It usually does not take long, so please visit again shortly. During maintenance, you can still use the NAVER Booking and KakaoTalk Channel links shown on the notice page for bookings and inquiries.
