Keratin clinic, moisture clinic, head spa, scalp care. These are condition and comfort services — they make hair feel and behave better and help colour sit evenly. They are not medical treatment, and we won't pretend otherwise.

Happynian Hair Salon Busan Seomyeon offers a keratin clinic from ₩160,000, a moisture clinic at ₩100,000, and head spa at ₩35,000 standard or ₩50,000 relax, plus care for coloured and bleached hair and scalp-care services.
The keratin clinic focuses on smoothing and structure and is the usual choice after colour, bleach or perm. The moisture clinic focuses on hydration. These are condition services — they improve how hair feels and behaves, but they are not medical treatment for the scalp or for hair loss.
Treatment is the service most often sold badly. The pitch is usually "repair," which is not a thing that happens — hair is not living tissue and damage to it is structural and permanent. What a treatment genuinely does is improve condition, smoothness, manageability and how evenly the hair takes and holds colour. That is worth paying for. It is just not a miracle, and you deserve to be told which one you are buying.
Reviews here mention the clinic working well, the shampoo and massage being good, and the products feeling like quality. Those are honest, achievable outcomes, and they are the ones being offered.
This is where treatment earns its money. Colour and bleach both open the cuticle, and hair with an open, uneven cuticle grabs tone unevenly — which is why the ends of coloured hair fade differently from the mid-lengths.
A treatment run alongside a colour service helps the tone sit more evenly across the length, and clients here regularly mention that the hair felt less damaged when the two were done together. That is individual experience rather than a guarantee, but the mechanism behind it is real.
The salon's main structural treatment, priced by length:
| Short | ₩160,000 |
|---|---|
| Medium | ₩180,000 |
| Long | ₩200,000 |
Usually chosen after colour, bleach or perm, or by anyone whose hair has stopped feeling smooth through the mid-lengths and ends.
These get confused constantly, and the confusion costs people money.
| Keratin clinic | Straightening / magic | |
|---|---|---|
| What it does | Smooths and conditions | Changes the hair's shape |
| Chemical change | No permanent reshaping | Yes — permanent |
| Result | Smoother, easier to manage | Straight until it grows out |
| Lasts | Weeks — a condition service | Months — grows out from the root |
| Choose if | Hair feels rough or porous | You want the shape itself changed |
If your goal is genuinely straight hair, see volume magic and sleek perm on the perms page instead.
₩100,000. For hair that reads dry, dull or lifeless rather than structurally damaged. Different problem, different answer — and a stylist who recommends the more expensive keratin clinic to someone who needs hydration is not doing the job.
| Standard head spa | ₩35,000 |
|---|---|
| Relax head spa | ₩50,000 |
The shampoo and massage are the parts clients mention most in reviews. The standard spa is the shorter service; the relax runs longer and is the one to book if the point of the visit is the hour itself.
The head spa and scalp-care services here are comfort and condition services. They are not medical treatment and they do not treat scalp disease or hair loss. If you have a scalp condition, please see a medical professional. Hair services may also be restricted if you are undergoing scalp injection treatment — please tell us before booking.
Often the right call, and often the right first call. Where hair has been bleached, black-dyed or repeatedly treated, your stylist may recommend a treatment before a perm or a colour rather than alongside it — because the service you want works better on hair that is in a condition to take it.
If that is the honest recommendation, you will get it, even though it means booking twice.
A standard head spa is ₩35,000 and a relax head spa is ₩50,000. The keratin clinic starts from ₩160,000 for short hair, ₩180,000 medium and ₩200,000 long. The moisture clinic is ₩100,000. Prices are starting prices and are confirmed before the service begins.
They address different things. The keratin clinic focuses on smoothing and structure, and is the usual choice for hair that has been coloured, bleached or permed. The moisture clinic focuses on hydration, and suits hair that reads dry or dull rather than structurally damaged. The keratin clinic starts from ₩160,000; the moisture clinic is ₩100,000. Your stylist recommends based on what your hair actually needs.
No. A keratin clinic is a treatment — it smooths and conditions the hair. Straightening is a chemical service that permanently changes the hair's shape. They can look superficially similar in a photo but they do different things and last differently. If your goal is genuinely straight hair rather than smoother hair, say so at consultation and you will be pointed to the right service.
Yes, and it is often a good idea — a treatment at the colour appointment helps tone sit more evenly on porous ends. Mention both on WhatsApp so enough time is reserved.
A treatment improves how hair feels, behaves and looks, and helps it hold colour more evenly. It does not permanently restore damaged hair — damage is structural. Anyone promising permanent repair is overselling. What is realistic is a noticeable improvement in condition and manageability, and reviews here mention that improvement consistently.
Around one hour is the salon average across services. The relax head spa runs longer than the standard. Your estimated duration is confirmed with your price before starting.
No. The head spa and scalp-care services here are comfort and condition services, not medical treatment. They do not treat scalp disease or hair loss. If you have a scalp condition, please see a medical professional.
Please tell us before booking. Hair services may be restricted if you are undergoing scalp injection treatment. Message on WhatsApp and your stylist will advise on what is appropriate.
