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.

General and gift-certificate guests pay a ₩30,000 deposit per person. If payment is not confirmed within two hours of the request, it is cancelled; please make a new reservation. Changes or cancellations are accepted until 17:00 on the day before a weekday reservation, or until 17:00 two days before a weekend or public-holiday reservation. After the deadline, ₩30,000 is deducted from the deposit or Membership balance.

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 tell us you will use a gift certificate when booking, and be sure to bring the physical card with you. A separate ₩30,000 deposit is required. After you attend and complete the service, the deposit is returned in full once the physical card has been collected or the remotely issued certificate has been marked as used in our records.

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.

Please tell us about any aroma allergy before booking. After checking the ingredients and your condition during consultation, we can omit the relevant aroma, substitute another one, or provide the service without any aroma when necessary.

Yes. Consultation about preferences or lifestyle is kept to the level you want, and we can minimize conversation if you prefer a quiet rest. However, we confirm essential safety information with every guest, including allergies, pregnancy, your condition that day, ability to remain lying down, and the condition of the treatment area.

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

Please let us know before booking if any of these apply. We will discuss the available options with you.

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.
