In short

For an easy-to-style, lighter mid-length look and a spring refresh, the layered cut plus layered perm at Toni&Guy Seongsu was a satisfying choice.

It was a lovely spring day for a light, fresh change of mood with a layered perm~

Maybe it's because it's spring, but I suddenly wanted to change up my hairstyle. After a heavy, stuffy winter look, I was after something lighter and livelier, so this time I switched things up with a cut and a heat perm to refresh my whole vibe. Today I visited Toni&Guy Seongsu, a steadily popular spot in Seongsu~^^

Toni&Guy Seongsu location and booking: is it close to Ttukseom Station?

Toni&Guy Seongsu is on the 2nd and 3rd floors of the building at 35 Sangwon 1-gil, Seongdong-gu, Seoul, and it's close to Ttukseom Station, so it's easy to get to. It gets a lot of visitors, so I recommend booking ahead.

I visit hair salons in Seongsu quite often, and this Ttukseom salon is especially busy, to the point where a reservation is a must. The 2nd floor was so full I could hardly find an empty seat, and the 3rd floor mostly runs on reservations too, so walk-ins may have to wait. Please book before you go.

First impressions and service: drinks and snacks for my husband too

The moment I walked into Toni&Guy Seongsu, I could feel how clean and well organized the whole system was.

From changing into the gown onward, the staff guided me in a natural, comfortable way, and I loved that they also gave drinks and snacks to my husband, who came along.

You can really feel that this Ttukseom Station salon cares about customer comfort, not just the treatment itself. The longer a salon visit goes, the more tiring it gets, but thanks to this thoughtful service I was happy with the whole experience today^^

Designer consultation: how I chose a mid-length layered style

After a thorough consultation with the designer at Toni&Guy Seongsu, I decided on a slightly mid-length style with layers added. They made their recommendation considering my face shape, current hair condition, and even my usual styling habits.

I liked that they didn't just push a trendy style but found a direction that suits me personally. The style I ended up with was a slightly mid-length cut with layers, light and full of movement~

The layered perm process: why a long session wasn't tiring

The layered perm at Toni&Guy Seongsu went in this order: cut, shampoo, perm, then shampoo again. What impressed me most was the shampoo chair. It's a recliner, so I could lie back comfortably, and a light scalp massage was included, which I was really happy with.

Two designers also worked on me together, so time passed faster than I expected. I felt almost none of the fatigue you usually get with a perm, and the relaxed, pampered feeling was wonderful.

After the layered perm: volume and morning styling time

Tidying the ends with the layered cut made my hair much lighter overall, and the volume came back so it looks fuller. The biggest plus is that I spend less time drying and styling in the morning.

I used to worry about thin, empty spots, but this style adds dimension, so they're naturally covered~ Styling is easier now, so my everyday satisfaction is definitely higher.

Before and after: mid-length hair finished with a layered cut and layered perm

The key to this treatment wasn't cutting length but bringing movement and volume to my heavy, straight-falling hair.

Before and after comparison of the layered cut and layered perm

In the before state, there were hardly any layers and the ends were bunched up heavily, which felt stuffy.

The layered cut tidied the ends and added layers for a light flow, and then a layered perm with natural curls on top built up the dimension for the finished style.

Mid-length hair with dimension from the layered perm

Before style features

  • Heavy, straight look with almost no layers
  • Ends that flare out and look puffy
  • Not enough volume, so the overall impression was flat

After style changes

  • Lighter ends and a natural flow from the layered cut
  • A mix of C-curl and S-curl waves brought to life by the layered perm
  • Revived volume for a much fuller, more dimensional feel
  • Easier styling, so a blow-dry alone can finish the look
After mid-length style with revived volume

For mid-length hair, the most important things are the 'end line' and the 'volume position', and in this style the curls flow naturally from below the face line, so the overall balance is much better.

The result is a definite change from a heavy, static feel to a light, polished mood, so if you want a natural change for the spring season, the layered cut and layered perm combo was definitely a satisfying choice~

To the designers at Toni&Guy Seongsu, thank you for giving me a style I absolutely love today~^^
