Dongtan Bansong-dong lash studio, ₩40,000 keratin perm: Onyu Lash

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!

Where is Onyu Lash, and how do you park and book?

Onyu Lash is a lash lift studio in Banson-dong, Dongtan, open Mon–Sat 09:00–16:00. It's 100% appointment-only, so you book your visit time through Naver Reservations. You can also check out their work on Instagram.

Look for the mint-colored Green Nail sign and the Onyu Lash banner out front. You can park in the lot behind the building or use Banson-dong's public street parking — the first 1.5 hours are free!

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

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!

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

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

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 💗
