How does an ash dye in Hongdae go, from consultation to color?

Consultation with the head designer before ash dye
Checking hair color and condition before dyeing

The ash dye at Juno Hair Hongdae Entrance Branch started with a consultation with the head designer, haha. She told me my current hair color and checked my hair condition first. She didn't just match the color I asked for; she explained the direction that would look prettiest on my hair as it is, which made me trust her. The consultation was so thorough that I could see why so many customers come back!

Americano and snacks served during the treatment

While the dye was being mixed, a staff member brought me an americano and snacks, so I could sip it and relax through the treatment, haha

Did the ash dye irritate the scalp?

They carefully sprayed a scalp protector on before dyeing, and maybe because of that I felt almost no irritation during the treatment, which was great, haha

Shampoo room, coating treatment and the finishing cut

The shampoo room at Juno Hair Hongdae Entrance Branch is set up for one person at a time, so I could be looked after much more comfortably. The lighting was soft and it was quiet, enough that it felt like a little break. My hair is the type that loses dye really easily, so to help the color last they finished with coating care too..! These thoughtful little touches were what I really liked, haha. They even gave me a refreshing scalp massage, so it felt healing :)

After the shampoo they thinned out my length and volume a bit and styled it, haha. Getting neater and prettier by the minute...!

Faded, red-tinged hair: before and after the ash dye

Before the treatment, my dye was old and the color had faded a lot, so it had turned reddish and the color was left in a patchy, in-between way that looked messy, right? ㅠㅠ My hair also looked really heavy and needed tidying up.

After the ash color dye at Juno Hair Hongdae Entrance Branch, the redness was naturally knocked down and the whole look became much more polished..! They cut it to keep my curl, so the frizzy feeling got tamed, and my hair looked healthier overall too. The color isn't too much either, just the calm ash color I wanted, so I'm totally satisfied!
