Gangnam hair salon blue ash brown color and 3-step clinic: Heeol Hair

In short

Heeol Hair Gangnam Flagship Store is a hair salon in Gangnam, Seoul, 290m from Exit 6 of Sinnonhyeon Station. Hair that had faded to orange and red tones was toned down with a blue dye for a full blue ash brown color, along with a 3-step hair clinic and a cut, all in about 1 hour 30 minutes. Both the toned-down autumn color and the glossy finish made the visit to Heeol Hair worth it.

The salon had an antique, upscale, and calm vibe💛

Consultation and what was booked: full color, clinic and cut

After consulting with designer Subin, we decided to go with a full hair color, hair clinic, and haircut☺️

She really gave great hair consulting advice tailored to me!! ✨

There was even a separate Hee All Hair membership perk and drink menu😌

I sipped a sweet iced tea and had some cookies for a sugar boost while the coloring was happening😄 The salon's atmosphere was so nice that getting my hair done felt like sitting in a café🙆🏻‍♀️

Blue dye over faded orange and red tones for blue ash brown

My hair color at the time was faded, showing both orange and red tones at once, so blue dye was used to tone it down into a calm blue ash brown color.

Designer Subin worked carefully and meticulously, and she was fast with her hands so the coloring went by quickly😉🎶

What the 3-step hair clinic involved

After shampooing in the shampoo room, the clinic treatment began — I got to lie back comfortably for it😆

The clinic had 3 steps total: removing buildup from the hair, then supplying moisture and nutrients, and finishing with a nourishing coating step☺️

They even covered me with a blanket partway through, so I could relax during the clinic😌

After the full color, the toned-down shade gives off a strong autumn feel, and the hair clinic left my hair insanely shiny and soft😍 The color was calm and clean, and I loved it♥️

You all know how important the final hair result really is!!🥹

Honestly… I really, truly loved this hairstyle😍

She also explained the causes of hair damage from frequent treatments and frizziness, and designer Subin styled my blow-dry to match my image🫶 She kindly explained hair care and maintenance methods throughout the treatment too😊

A lucky turtle and a treatment gift at Heeol Hair

Designer Subin also gave me a lucky turtle as a gift😇 Little events like this are so touching💛✨ I drew the turtle that symbolizes luck, health, and wealth🐢
