Why I got a bob perm at Onzon Hair in Wangsimni

At Onzon Hair, a hair salon in Wangsimni, I finally got the bob perm I'd wanted for ages. As the weather got hotter, my hair felt so heavy and stuffy every time I looked in the mirror. I kept telling myself I had to do something about it, and day after day went by, and these days tying it up was my only option.

Visiting Onzon Hair Wangsimni

This is Onzon Hair's Wangsimni branch. For years I went to just one place, but after the owner-stylist got sick and couldn't work anymore, I was wondering where I'd find my next go-to salon for life, and then I found Onzon Hair.

It was early on a weekday morning, and I was shocked by how many customers had reservations!!

Half-curly long hair: how did the bob perm change it?

Before the bob perm, my hair was long, half-curly and had no volume. I went to Onzon Hair after seeing a friend's hair done there, and now I get why she recommended it. Anyway, looking at my hair again, it's hopeless!!! Being half-curly, the hair on top came down messy and frizzy, which I could hardly stand, and even when I blow-dried it, it never got any volume.

The changed style after the Onzon Hair bob perm

Wow, is it fair for a style to change this much? Even in this heat, I'm heading out feeling great with the fresh look of a bob.

With hair that was just long and tedious, my style felt dull and heavy, but now it's easy to style, and I finally understand why bobs are so loved.

How does the bob perm at Onzon Hair work?

The bob perm at Onzon Hair was completed after a thorough consultation, then shampoo, cut and perm. What impressed me was how fully they reflect each customer's needs, one person at a time.

I hardly ever see the back of my head, and it turns out it had grown this long.

After the perm, I looked human again!! The trailing length was cut neatly, and natural waves were added so the hair looks full. It looked so natural that I couldn't believe it was done today.

Maybe because of the careful consultation, I liked the lively hairline, and the perm gave my hair a firm, springy feel. It blow-dries really well.

Won't the perm get boring? Drinks, snacks and the QR scalp check

At Onzon Hair in Wangsimni, I got my perm comfortably without any boredom. They offer all kinds of drinks and snacks, which was great. Doing the scalp diagnosis with a QR code was a nice little activity too.

Sitting in one place for a long time makes my body ache, but I moved around for the wash, the perm and the cut, changing seats, so I didn't notice the time pass.

Is styling at home easy after the bob perm?

Styling after the Onzon Hair bob perm is easy and simple. You can create a different mood depending on whether you wear your bangs down or up, and I loved that hair doesn't fall out as much when I wash it. The ends used to tangle and not come down when I brushed while drying, but with just a perm they became this smooth! After washing, I just towel-shake it dry, mix a little curl cream and oil I have at home, and it stays moist all day.
