Volume magic straightening + mid-length layered cut after a year
[ Toni&Guy Seongsu ] is a space that respects each client's individual style while completing signature looks with the latest trends and original techniques.
Today I finally visited — after a whole year! — to tame my frizzy hair with a "volume magic straightening" and a "mid-length layered cut." Designer Taeri specializes in bob perms and low-damage glossy straightening, but it turns out she's a total expert at mid-length layered cuts too! If you want a fall hair transformation, go see Taeri ••🧡
Before the treatment, we discussed what style would suit me, and the result ended up looking just like the photos I showed her — I was really satisfied 💯


My hair before the treatment
My hair is severely half-wavy, and after getting a straightening treatment last year it had gotten pretty messy 😏 My husband kept asking when I was going to escape the caveman hairstyle ••• Today, with designer Taeri, let's see the transformation 🪄

Starting with shampoo and clinic treatment
First up was a refreshing shampoo 🧴 Taeri gave me a satisfyingly thorough shampoo and massage 🥹🫧 From protein shampoo to a clinic treatment for my dry, damaged hair, she was really meticulous


The drink and cookies offered during the treatment were a nice touch too
She cut my frizzy hair and did the neutralizing process. After neutralizing, she carefully straightened my hair with a flat iron. She went through it strand by strand, even the tricky spots, straightening both sides so thoroughly that it felt so satisfying ,,🍃🌬️
When I've had volume magic straightening before, it often didn't straighten properly and got wavy again from damage — that was my biggest worry, but Taeri put those worries to rest and gave my hair a fresh, damage-free start

The finished mid-length layered cut
My wavy, caveman-like hair,, transformed into something light and neat after meeting bob specialist Taeri at [ Toni&Guy Seongsu ]
Even after finishing the straightening, Taeri carefully did the mid-length layered cut, so I could properly welcome fall. Once everything was done, I left the salon feeling so much lighter. A real mood reset at [ Toni&Guy Seongsu ], a Seongsu hair salon 🎶🎵
