Sinnonhyeon hair salon slick magic perm for long waves: Park Jun

In short

Park Jun Beauty Lab Gangnam Branch is a hair salon in Gangnam, Seoul, about 2 minutes on foot from Sinnonhyeon Station. Long wavy hair that had gone frizzy from damage was smoothed with a repair perm combining the Shiseido repair program and a Re-born perm, with a magic straightening step added for a slick finish. The result kept the weight of the long hair while leaving it glossy and tidy enough to wear down.

Long slick hair styled with a Re-born repair perm

Why damaged long waves sent me to a Sinnonhyeon hair salon

My hair's been getting longer lately and there's a lot of wave in it, but the problem is it's really damaged.. Instead of nice-looking curls, my hair just looked frizzy overall and the ends felt dry, so it made me a bit self-conscious about wearing it down. Seeing celebrities these days with that shiny, swishy hair made me jealous haha, so this time instead of just getting a perm, I looked for somewhere that could also take care of the damage, and Park Jun Beauty Lab Gangnam Branch kept coming up as a recommended Sinnonhyeon hair salon, so I went.

Park Jun Beauty Lab Gangnam Branch: location and booking

What happens in the consultation before the perm

What I liked most on my first visit was the consultation before the treatment.

Consultation on hair condition before treatment

After I told her the style I wanted, she carefully checked my current hair condition, and considering my face shape and how I usually style my hair, she explained in detail which look would suit me. It didn't feel like she just jumped straight into the perm I asked for — I liked that we thought together about what approach would work best for my hair right now.

Before photos and why I chose the Re-born perm

Here's the before! Lots of hair, patchy color, and the ends were pretty damaged too. So overall it just looked frizzy.. What I chose was the Re-born perm at this Gangnam Station hair salon, Park Jun Beauty Lab. I already had wavy long hair, but I wanted to tidy up the frizziness and get an overall clean, shiny, slick perm look.

Preparation for the Re-born perm
Shiseido products used for the Re-born perm

The Re-born perm apparently combines the Shiseido Repair program with a Re-born perm. On top of that, they added detox care, which she explained helps strengthen the hair overall while boosting shine and curl elasticity. Before getting into the main treatment, she first diagnosed my current hair condition using Shiseido clinic shampoo.

Diagnosing hair condition with Shiseido clinic shampoo

The Shiseido Salon Solution Clinic is described as a professional care program that systematically manages the hair inside and out to boost the effect of chemical treatments and help results last longer. Hearing that explanation, I got so excited for the final result!!

Pre-treatment and protein ampoule care process

Pre-treatment, protein ampoules and applying the perm solution

After the shampoo, she did pre-treatment care with 7 natural protein ampoules added in. I was worried that a perm might make my already-damaged hair even drier, but she checked on the condition of my hair throughout, which put me at ease.

How my hair felt after the softening stage

Especially once the softening process went well, I could already feel my hair changing. When I touched it, the parts that used to feel rough became a lot softer and got that swishy feeling. It was fascinating to see my hair texture change even before the perm was finished.

Trimming the length and ends of the hair

Adding the magic straightening step for a slick finish

After that, she trimmed the overall length and ends neatly, and also did a magic straightening step for the slick look I wanted. She tidied up the original wave and frizziness while making sure it didn't end up looking too flat or heavy.

The finished slick repair perm on long hair

Looking at the finished hair, it was pretty close to what I wanted. In particular, it kept the weight that long hair has while looking a lot more polished overall, and the shine made it look much cleaner. Before, whenever I let my hair down it looked frizzy so I kept wanting to tie it up, but now I feel fine leaving it down.

Finished shiny slick Re-born perm

Most of all, true to the name repair perm, I was so satisfied that my hair looked much healthier than before the treatment. I could really feel how the dry, frizzy hair had turned soft and swishy. So happy with this slick perm at Park Jun Beauty Lab, this Gangnam hair salon!!!

Who this Re-born repair perm suits

If you have long hair with existing waves that look frizzy because of damage like mine did, I think it's worth getting a consultation on your hair condition first rather than just going straight for a perm. I especially liked the consultation that recommended a style based on my face shape and hair condition, and junior stylist Yeonjae explained everything kindly from start to finish, so it was a comfortable experience.

If you're looking for a hair salon near Sinnonhyeon Station or want to tidy up damaged long hair into a clean, shiny style, I'd recommend Park Jun Beauty Lab Gangnam Branch.
