## In short

Salon de L is a hair salon in Seongdong, Seoul, on the 2nd floor of Tenz Hill Mall in Wangsimni. The Tricyscore hair clinic at Salon de L treated hair roughened by daily flat iron and Airwrap use, running through four steps: product application, heat treatment, steaming, cleansing, and one more application. After the blow-dry the hair felt moist and settled, making this a treatment worth repeating for anyone who uses heat tools often.

I use a flat iron and an Airwrap almost every day, so my hair had gotten rough and frizzy. While looking for a Wangsimni hair salon recommendation, I found Salon de L and got a Tricyscore clinic done. It wasn't just one product applied and done — it's a four-step process, so the whole thing felt pretty thorough, and afterward my hair genuinely felt moist and settled. Very satisfying.

## Why I chose a hair clinic at this Wangsimni hair salon

*Before*

I'm not really the type who just air-dries my hair — I use a flat iron or Airwrap almost every day. At some point I really started noticing how rough my hair had become.

*Before*

The ends especially felt frizzy, and running my hand through it didn't feel as smooth as it used to.

*After*

So this time, instead of a cut, I decided to focus on overall hair condition care. That's how I ended up at Salon de L.

## Inside Salon de L on the 2nd floor of Tenz Hill Mall

Salon de L is on the 2nd floor of Tenz Hill Mall. Walking in, the wood-tone interior caught my eye right away, and overall it felt warm and cozy. The seats were neatly arranged and the treatment space had plenty of room, so I could sit comfortably.

For a treatment like a clinic that takes a bit of time, the shop's atmosphere honestly matters a lot. I liked how calm everything felt overall.

### Drinks and snacks served during the treatment

Once I sat down, they prepared drinks and snacks too — iced tea, butter biscuits, and baked rice chips. ❤️ I picked the lemonade out of the options.

*Designer Hansol was very kind!*

Since the clinic has several stages and takes some time, sipping a drink and snacking in between made the waiting feel not boring at all. That little touch made me pretty happy.

## How the Tricyscore clinic works in 4 steps

![Informational material on the Tricyscore clinic](https://img.superchart.com/images/salon-de-aile-trisyscore-hair-clinic/salon-de-aile-trisyscore-hair-clinic-09-9e8n9-900.webp)

What I received this time was the Tricyscore clinic. I was told it's a treatment system that runs through a total of four steps.

![Explanation of the Tricyscore 4-step system](https://img.superchart.com/images/salon-de-aile-trisyscore-hair-clinic/salon-de-aile-trisyscore-hair-clinic-10-ce7rk-900.webp)

Each step uses a different product with a different role, and they went through them in order.

- Step 1｜Fill — filling in what the hair needs
- Step 2｜Coat — protecting the hair
- Step 3｜Wrap — wrapping the cuticle with high-molecular keratin
- Step 4｜Hydrophobize — managing the cuticle surface

And at the end, there was also guidance on a home-care step to follow up with.

### More product options at Salon de L than I expected

Watching the treatment happen, I noticed there was quite a wide range of Tricyscore products — KL, KM, CO, CEc, CEm, 18S, KH, and more were all on hand. They explained that they don't use the same products on everyone; instead they pick products suited to each person's hair condition. So after checking my hair's condition, they used the right products for each step.

### Step 1｜Protein care after the shampoo

First they shampooed my hair and started the clinic in earnest. They carefully applied the step 1 product to all my hair, explaining this part is protein care.

They sectioned my hair and applied it carefully so the product got in between every strand.

After applying the product, they did a heat treatment with an infrared device. It wasn't just apply-and-wait — heat treatment was worked in between steps, which really gave the sense that the process was broken down in detail.

### Step 2｜Product application and steaming

![Applying the step 2 product](https://img.superchart.com/images/salon-de-aile-trisyscore-hair-clinic/salon-de-aile-trisyscore-hair-clinic-14-18eus-900.webp)

After step 1 finished, they applied the step 2 product to my hair again.

![Steaming process during the clinic](https://img.superchart.com/images/salon-de-aile-trisyscore-hair-clinic/salon-de-aile-trisyscore-hair-clinic-15-iqr9o-900.webp)

This time steaming was involved. I waited a bit under the warm steam, and it went differently from the previous step. They rinsed my hair lightly once in between before moving on to the next step.

### Steps 3 and 4 of the Tricyscore clinic

![Spraying the step 3 product onto the hair](https://img.superchart.com/images/salon-de-aile-trisyscore-hair-clinic/salon-de-aile-trisyscore-hair-clinic-16-rl5x6-900.webp)

After that, they sprayed the step 3 product evenly all over my hair. The final step 4 product was also applied thoroughly all over.

Going through the whole process, I understood why it takes some time. Application → heat treatment → steaming → cleansing → additional application.

![Hair after the step 4 product application is complete](https://img.superchart.com/images/salon-de-aile-trisyscore-hair-clinic/salon-de-aile-trisyscore-hair-clinic-17-9n9xm-900.webp)

With steps continuing like this, it was clearly a very different process from just applying a single treatment at home.

## After the final shampoo and blow-dry: how did my hair change?

After all the clinic steps were finished, they did a final shampoo. Then they blow-dried my hair nicely.

*After*

Honestly, it's sometimes hard to feel much difference while hair is still wet. But once it was fully dry, my hair felt more moist and settled than before. It fell more calmly overall, and it felt softer to the touch too. I took photos afterward, and the change really shows up better in pictures.

### Worth it if you use a flat iron or Airwrap often

For people like me who use a flat iron or Airwrap often, I think consistent hair care really matters. Rather than using heat tools daily and just doing a quick treatment at home, it seems better to get a clinic at the salon periodically and combine it with home care. This Tricyscore clinic in particular included guidance on home care at the end, so it was nice that I could keep up the routine at home.

## Was the Tricyscore clinic worth the price?

![After the Tricyscore clinic is finished](https://img.superchart.com/images/salon-de-aile-trisyscore-hair-clinic/salon-de-aile-trisyscore-hair-clinic-19-2s7rr-m-900.webp)

What I liked most about the Tricyscore clinic at Salon de L was really the thoroughness of the process. Split into four steps, with products, heat treatment, and steaming built into each stage, it felt clearly different from a regular treatment. And honestly, for this much process, the price felt like good value. Rather than doing this once and calling it done, I think it's worth getting regular care — especially for people like me who use heat tools a lot and need to manage their hair condition.

Salon de L, which I visited while searching for a Wangsimni hair salon recommendation. It was easy to find on the 2nd floor of Tenz Hill Mall, and I could relax through the treatment in a cozy wood-tone atmosphere. Above all, the Tricyscore clinic I got this time, with its thorough 4-step process, is worth checking out if your hair tends to feel rough or frizzy. Good value too, and cheaper if you use the first-visit event! If you're someone who uses a flat iron or Airwrap often like me and needs hair care, or if you're looking for a salon to get a hair clinic in Wangsimni, this place is worth considering. 🤍 I'm planning to go back next time for a dye job or a perm.
