Seongsu hair salon: wedding-shoot trim + hydration clinic, Onzon Hair

My hair had grown too long and gotten frizzy again, so I went to Onzon Hair Seongsu, a hair salon near Ttukseom Station, for a women's cut and a clinic. The price is great for what you get, and I loved the result too.

Inside Onzon Hair Seongsu and its waiting area

The inside of Onzon Hair Seongsu was so neat and tidy, as if it had only just opened, and I loved it. The staff seem to care about cleanliness, because nothing felt messy at all 🤍

I arrived a little before my appointment and was shown to a seat. Every seat has a charger, such a thoughtful touch, so I could wait comfortably on my phone.

They also set out light drinks and snacks for the wait. You can choose coffee, green tea or dungulle tea (Solomon's seal tea), and I went with the dungulle tea!

How much do a cut and clinic cost at Onzon Hair Seongsu?

At Onzon Hair Seongsu, a women's cut was ₩22,000 for a first visit and the hydration clinic was ₩100,000. Even with both together, it comes to under ₩130,000!

It was my first visit, so I didn't request a particular stylist, but you can book a specific designer too!! Best of all, you can see the price when you book, so there's no nasty surprise bill after walking into a salon, and I really liked that.

These days a single cut easily tops ₩30,000, so ₩22,000 for a first-visit women's cut felt like pretty good value. And I got the hydration clinic for just ₩100,000.

How did the trim go a month before wedding photos?

Before the treatment, my hair was just so frizzy overall, ugh, and the ends were badly damaged. I have wedding photos about a month away, so I told the head stylist (siljang) in advance, and she suggested not cutting much length and just tidying the ends.

She said that if she cut as much as I'd asked, adding waves would make it even shorter and it wouldn't look pretty, so we just went with an end trim. Brides-to-be, take note~!

• Keep the length as long as possible, thinking ahead to adding waves
• If your left side is your better side, part it on the left
• Silky, smooth hair is a must!!

On top of that, I also asked for side bangs and those little face-framing wisps that pop out when you tie your hair back 🤍

How does the Onzon Hair hydration clinic work?

The hydration clinic at Onzon Hair Seongsu takes over 30 minutes, lying back at the shampoo station after the cut. Lying down is really comfortable and makes you drowsy and limp, and it felt almost like a head spa.

Step 1: Applying the treatment

My hair was really tangled, so at first the comb wouldn't go through, but after they worked the treatment in gently and combed, it was amazing how smoothly it slid by the end!

After the first product is fully applied, they put this odd contraption over your head, haha. It blasts a little steam and it's so warm that you start nodding off. I figured it's something like putting on a hair mask and a shower cap.

Steps 2 and 3: Product 2 with a pressure-point massage, then a cooling product 3

Next they apply products 2 and 3. While applying product 2 they also press and massage my scalp, which felt so good... this treatment is the best...

I don't know what product 3 was, but my scalp felt super tingly and cool!! Like I'd squeezed a whole tube of toothpaste onto my head, haha.

Hydration clinic results: frizzy ends to silky hair

When it was done, can you see how silky my hair got from just one hydration clinic!! I've had quite a lot of clinics, but getting a result like this at this price is really hard, so I was very satisfied.

Final verdict on Onzon Hair Seongsu

This good-value salon near Ttukseom Station, Onzon Hair Seongsu, satisfied me with both the cut and the hydration clinic. My partner went too and came back raving about how soft their hair was. I was really happy too, haha.

I was treated by the head stylist! The older I get, the more I think healthy hair is a big part of looking elegant. Go get a clinic at this bargain of a salon~!
