Why did I go to U Art Hair Hongdae for root dye?
If you keep putting off root dye, there comes a point where every time you look in the mirror your whole head just looks messy.

I hadn't touched up my roots in a while, so the color difference at the crown was obvious, and my hair didn't look neat whether I tied it up or wore it down. So I went to U Art Hair Hongdae, a hair salon in Hongdae known for good dye work.



The area around Hongik Univ. Station is easy to get to and full of salons that do dye well, so choosing was tough, but this time my priority was a place that does root dye carefully. So I visited!



A full dye job felt like too much, so I went planning to keep my current hair color and just match the root area naturally.

My hair before the treatment
My roots had grown out a lot. My hair condition overall wasn't bad, but because the root color was different, it looked unkempt! Under the lights the line was even easier to see, so it really bothered me~
How does the root dye consultation work at U Art Hair Hongdae?
At the first consultation, U Art Hair Hongdae carefully checked my existing hair color first,

and they explained that it's not just about covering the roots darker, but about matching the tone so it connects naturally with the already-dyed hair. That made me trust them.

What I wanted was a tidy root dye that doesn't show! They understood that right away, which I liked,

When you look up Hongdae dye recommendations, there are lots of reviews of pretty full-color jobs, but with root dye, a natural connection is the most important thing, right?

If it comes out too dark or too light, the line actually shows more. At U Art Hair Hongdae they matched the color by looking at both my existing hair color and my skin tone.

How careful was the root dye process?
The root dye process was careful too. They section the root area and apply the dye, and it didn't feel like a quick, sloppy swipe,

They split my hair into fine sections so no spot was missed, and I could feel them paying extra attention to the noticeable areas like the crown, hairline and parting.
Root dye isn't a long treatment, but I think how carefully it's done makes a clear difference in the result.
If you value this kind of attentive consultation and process among the salons near Hongik Univ. Station, I think you'll be satisfied.

They also checked in from time to time while I waited to see if anything was uncomfortable, so I could relax through the whole thing,

Before and after root dye: was the line natural?
After the shampoo and blow-dry, the before and after difference was definitely visible. The line between my roots and the previously dyed hair was neatly blended, and my whole head looked much tidier and calmer!

If before was hair with obviously grown-out roots, after was hair that looks well cared for! My hair color didn't change drastically, yet my overall impression looked much more put together. Just a root dye changed the whole vibe~

The color connected naturally with my existing hair, so it didn't look odd even up close, the roots didn't float apart from the rest, and I could barely feel any difference in brightness. I was happy with it.

When looking for a Hongdae salon that does dye well, a pretty color matters, but I think this kind of natural connection is the real skill.

Once the messy-looking roots were sorted out, my whole head looked much neater, and it was a proper mood refresh too.

Who is root dye at U Art Hair Hongdae right for?
U Art Hair Hongdae takes care of the thoroughness that matters most in basic treatments like root dye. I liked that they looked after me attentively from the consultation to the finish,

I'd recommend it to anyone near Hongik Univ. Station looking for natural root dye, and to anyone who finds a full dye job too much but wants their hair neatly tidied up.
