## In short

Onyu Lash is a lash perm studio in Bansong-dong, Dongtan, Hwaseong, with its own treatment room inside Green Nail. After daily eyelash curler use on downward-growing lashes caused lash loss, a ₩40,000 keratin perm at Onyu Lash gave a natural curl that keeps the eyes looking defined without a curler or mascara. The consultation and aftercare advice were good enough that a return visit to Onyu Lash is planned once the perm drops.

This is Dundooni, recording what I see and experience 🐻‍❄️

My lashes normally point downward with almost no curve, haha 😂 Still, I curl them with an eyelash curler every single day for the sake of pretty lashes. But curling them so much was making my lashes fall out, so this time I went to Onyu Lash, a lash lift studio in Dongtan, and got a natural curl perm!

## 1. Inside the treatment room at Onyu Lash

Onyu Lash's treatment space is tucked into a separate area inside Green Nail. It was bright, cozy, and had a really relaxed atmosphere overall!

The treatment bed had a pillow to support your head and a cushion to rest your legs on~

It was genuinely comfortable lying in the same position for a long time, and the director's touch was so gentle I actually fell asleep partway through, hahaha.

## 2. Lash design for your eye shape and keratin perm prices

✅ Before photos

![Close-up of lashes before treatment](https://img.superchart.com/images/dongtan-bansong-keratin-lash-perm-onyoo/dongtan-bansong-keratin-lash-perm-onyoo-11-1p8lb-966.webp)

Before the treatment, we discussed my lash condition and the curl I wanted. The director asked whether I wanted a dramatically lifted look or a natural one, and I asked for a natural curl!

![The no-glue lash lift procedure in progress](https://img.superchart.com/images/dongtan-bansong-keratin-lash-perm-onyoo/dongtan-bansong-keratin-lash-perm-onyoo-12-14vb8-966.webp)

Since Onyu Lash has a specialist with a long beauty career, they don't just lift the lashes straight up — they design an elegant curve that considers your eye shape and double-eyelid line so the lashes don't touch the skin 😊 It's also done with a no-glue method, so there's no excess tension on the lashes!

✅ Price list

- Moisture-nourishing keratin perm ₩40,000
- Black tinting keratin perm ₩45,000
- Dual perm ₩60,000
- Straight recovery perm ₩30,000

I got the natural-curl keratin perm! At the time of my visit, first-time customers could choose between ₩10,000 off or a full-size nutrient serum.

## 3. Keratin lash perm before and after

The moment I saw the finished lashes, I was so happy with how prettily the curl turned out 💗 It curved up gently from the root without an overly sharp bend — exactly the natural feel I'd asked for.

✅ Before

Before the treatment, my lashes sank downward when viewed from the front, but after the perm, each individual lash came alive and stood out clearly.

✅ After

![Lashes lifted naturally after the keratin perm](https://img.superchart.com/images/dongtan-bansong-keratin-lash-perm-onyoo/dongtan-bansong-keratin-lash-perm-onyoo-16-1juvq-1200.webp)

My eyes look far more defined even without an eyelash curler or mascara! The curl was even on both sides too, with no clumping or twisting anywhere ✨

## How to care for a lash perm, and Onyu Lash return-visit perks

![Aftercare instruction sheet for the lash perm](https://img.superchart.com/images/dongtan-bansong-keratin-lash-perm-onyoo/dongtan-bansong-keratin-lash-perm-onyoo-17-1jjjh-966.webp)

After the treatment, they gave me a printed aftercare guide. On the day itself, you should wait at least 4 hours before washing your face, and avoid rubbing your eyes or using an eyelash curler. Mascara can be used starting the next day.

Lastly, I even got a cute little lash brush as a gift! If you bring the return-visit coupon next time, you can get ₩10,000 off or a COS lash serum — I think I'll go for the serum next time, hahaha.

## Dundooni's verdict on Onyu Lash

- A consultation that carefully confirmed the curl I wanted
- A comfortable, gentle treatment
- A natural yet clearly defined curl

The director was genuinely kind, and everything from the consultation to the result and aftercare was satisfying. If you're looking for a Dongtan lash lift studio that's great at natural curls, I recommend Onyu Lash~! I'm definitely planning to go back once this perm fades out 💗
