Hongdae hair salon: mint dye to tone down orange-faded hair, Juno Hair

In short

Juno Hair Hongdae Entrance Branch is a hair salon in Mapo, Seoul, about a 2-minute walk from Exit 2 of Hongik Univ. Station. The writer, whose hair ends had faded to red and orange, came in for a black tone-down. After a consultation, designer Lee Heon recommended a mint dye that uses complementary colors to cancel the warmth. The verdict: a calm dark color with the red neutralized and noticeably softer hair, a result the writer was happy with.

Why mint dye for hair faded to orange?

This is my story of getting a tone-down with mint dye from designer Lee Heon at Juno Hair Hongdae Entrance Branch. Every time I looked in the mirror lately, the ends of my hair had faded to a bright red and orange, and it was bothering me.

I went looking for a Hongdae salon to tone it down to black and ended up at Juno Hair Hongdae Entrance Branch. I was treated by designer Lee Heon, who is known for great skills, and I liked the mint dye so much that I wanted to write a review.

It's open daily from 10 a.m. to 9 p.m. and closed only on Seollal (Lunar New Year) and Chuseok (Korean harvest festival) days, so keep that in mind. I was happy with the facilities too: parking, Wi-Fi and pets are all allowed.

Salon atmosphere and shampoo area

Inside, big picture windows let in lots of light, and the interior is modern. There's a stylish herringbone-pattern wall and displays of high-end hair products.

The staff kindly kept my belongings and brought fragrant iced herbal tea and sweet cookies, which put me in a good mood.

One-on-one consultation with designer Lee Heon and the mint dye recommendation

Designer Lee Heon, who looked after me this time, has a rare eye that misses no detail, just like the title "a hair's breadth of difference" (한 끗 차이) suggests. Since she studied chemistry, she explained the chemistry of the dye and checked how damaged my hair was before giving me a personal consultation.

One-on-one dye consultation with designer Lee Heon

I had planned a tone-down to a dark color, but she said hair with strong red and orange tones like mine fades back to red quickly if you just put regular brown on it.

Color consultation for toning down red-faded hair

If I wanted to keep a lighter tone, ash brown would be the way to go, but she recommended mint dye as a trendy, effortlessly-good-looking color. Mint's complementary-color effect cancels the muddy red and orange in the hair and creates a subtle, classy black tone-down, she said.

The mint dye process

The actual service was careful too. First she applied a scalp protector to minimize irritation before the dye touched my head. Then she checked the damage and fading at the ends in detail and applied a custom dye evenly, with no patchiness.

Applying the custom mint dye

After the processing time, I moved to the shampoo area where the dye was rinsed out refreshingly, and she finished with a treatment that left my hair much softer.

Tips for keeping mint dye longer

She also gave me tips for caring for it at home. Because of how mint dye works, a faint bluish tint may show right after the service, and the color may bleed for about a week, so be careful with light-colored clothes and towels.

Lina's pick 🌟
  • Wash your hair with lukewarm water instead of hot water
  • Use a mildly acidic shampoo instead of a strongly cleansing regular shampoo
  • Don't leave hair wet after shampooing; blow-dry it right away

Leaving hair wet for a long time after shampooing also causes damage and color fading, so she said it's best to blow-dry right away.

Hair before dyeing

In the photos I took before the service, my hair looks dry and frizzy overall. Whenever light hits it, the orange and red tones stand out, and it looked damaged.

Hair after dyeing

After the black tone-down with mint dye, it was like I'd transformed into someone with different hair. The calm, deep dark color with the red tones gone even made my complexion look neater.

Even though I'd just dyed it, my hair felt softer than before the service and had a healthy shine, and I kept marveling every time I looked in the mirror.

I'm happy that the faded orange hair could be toned down so elegantly and naturally. 👍 Thanks to designer Lee Heon, who diagnosed my hair using her chemistry knowledge and fixed it with a trendy mint color, I feel like I found the hair of my life.
