Gangnam hair salon volume magic for wavy hair: Park Jun Beauty Lab

In short

Park Jun Beauty Lab Gangnam Branch is a hair salon near Gangnam Station in Seoul, a five-minute walk from Sinnonhyeon Station Exit 6. After a summer of tying up naturally wavy, frizzy hair, the writer booked designer Yeonjae for volume magic straightening plus bangs and side bangs, and the full process — shampoo, protein ampoule, straightening solution, flat-iron pressing and neutralizing — took 3 hours 30 minutes. The wave settled down smoothly and the side bangs came out in a soft, not-too-dramatic line, which made the long session worth it.

A Gangnam-Sinnonhyeon hair salon review: my volume magic straightening at Park Jun Beauty Lab Gangnam Branch.

Why wavy hair needs volume magic straightening twice a year

My hair is naturally a bit wavy, so I get volume magic straightening done about twice a year. This summer I just kept tying my hair up without thinking much about it, until one day I had plans and let my hair down — and it was so frizzy I knew I had to book a salon immediately.

Park Jun Beauty Lab Gangnam Branch: location and how to book

I visited Park Jun Beauty Lab Gangnam Branch. It's within a 5-minute walk from Exit 6 of Sinnonhyeon Station on Subway Line 9, so it's really easy to reach by public transport.

I made a reservation in advance through Naver Reservation and had my hair done by designer Yeonjae. I hadn't washed my hair before going, and it was a mess — I tie it up every weekday so I hadn't even realized how rough it had gotten, haha.

Consultation: volume magic straightening plus bangs and side bangs

Before the treatment started, I filled out a detailed consultation chart with the designer. Life had felt a little dull lately, so I wanted a small change and mentioned during the consultation that I'd like to try bangs and slightly lowered side bangs too. Designer Yeonjae immediately caught exactly what I wanted and the direction I was going for, so we decided to go ahead with the volume magic straightening.

The process: shampoo, protein ampoule and straightening solution

First I moved to the shampoo room. She used a nourishing, moisture-rich shampoo to replenish moisture inside the hair and washed it thoroughly, all the way through. After the shampoo, to minimize damage, she applied a protein ampoule evenly across all of my hair. Then came the careful, section-by-section application of the straightening solution. After letting it sit so the solution could absorb properly, I went back to the shampoo room to rinse it all out clean.

Flat-iron pressing and neutralizing at Park Jun Beauty Lab

Next came the flat-iron pressing, the core step of volume magic straightening. Designer Yeonjae carefully took each section of hair and pressed it with real attention. Her touch was so precise — keeping the natural volume at the roots while smoothing out the frizzy waviness.

After the pressing was done, the hair went through neutralizing. Finally, she shampooed once more, applied a nourishing ampoule, and dried it with a blow dryer to complete the whole treatment.

How long does volume magic straightening take? 3 hours 30 minutes

The whole volume magic straightening process took about 3 hours 30 minutes total. She brought me a cold drink partway through, and I spent the time catching up on things on my phone, so the 3 hours went by faster than I expected.

After: smoothed-out waves and a soft side bangs line

Finally done. Here's my hair after the volume magic straightening at Park Jun Beauty Lab Gangnam Branch — so much calmer, with the waviness under control. Designer Yeonjae picked up on exactly what I wanted right away, so it came out exactly in the style I was hoping for.

The messy, puffed-out frizz was smoothed down cleanly, and my hair overall looked so much calmer and glossier. The new side bangs also framed my face naturally, adding a sleek touch without feeling heavy.

Designer Yeonjae finished it in a line that matched exactly what I wanted — not overdone, just the right amount of pretty — so I was really satisfied.

If you're near Gangnam or Sinnonhyeon station struggling with frizzy wavy hair, or looking for a hair salon that's great at low-maintenance volume magic straightening, I'd recommend designer Yeonjae at Park Jun Beauty Lab Gangnam Branch.
