What it is
Wonjungyo Weekly Concentrate Treatment is the kind of product you reach for when your hair feels rough, flat, or over‑styled from the week. The creamy texture spreads easily through damp hair and rinses clean, leaving strands smoother and more manageable without heaviness. After one use, the surface feels softer and looks noticeably more polished—like a quick reset before the next round of heat styling or busy days. It’s a simple weekly ritual that keeps hair looking healthy with minimal effort.

Frequently Asked Questions
Is this authentic?
Yes. Every item is bought from an official seller in Japan, or direct from the brand for pre-orders,
never from resellers or grey market stock. Counterfeits and grey market listings are a real problem in
Asian beauty online, and buying only through official channels is how we rule it out.
What are your shipping rates?
On orders under US$75, shipping is a flat US$20 to the United States and US$10 to all other countries.
Orders of US$75 or more ship free, applied automatically at checkout. Your exact shipping cost is shown before you pay.
How long does delivery take?
These estimates are for International Airmail (Tracked) and include 3 to 5 business days of processing in Japan.
- United States: 12 to 15 business days
- Canada, United Kingdom, France, Germany: 9 to 12 business days
- Australia, New Zealand, Denmark, Finland, India, Indonesia, Italy, Netherlands, Spain, Sweden, Switzerland: 10 to 13 business days
- China, Hong Kong, Malaysia, Singapore, South Korea, Taiwan, Thailand, Vietnam: 8 to 10 business days

Actual delivery can be affected by customs clearance, seasonal congestion, or carrier delays in the destination country, all of which are outside our control.
Do you offer express shipping?
Yes. As of 22 July 2026, we offer International Express Mail through Japan Post. The cost is based on order weight and is calculated automatically at checkout.
Will I pay customs or import fees?
US orders: No. As of July 1, 2026, all US orders ship DDP (duties delivered prepaid), meaning we prepay all import duties on our end. Nothing is due at your door.
Orders outside the US: Possibly. Duties and import taxes are set by your local customs authority and are not collected at checkout, so any charges on delivery are your responsibility.
We're working on rolling out prepaid duties for more countries soon.
My hands feel so much better after a bath! The scent is also great!
I love these rescue pouches. I've been using Steven Knoll for a while now, but I can't find it anywhere...? It's moisturizing and holds my hair in place, so I'll go with this one!
I also use Chantry, and it has a lovely scent. The finish is smooth and easy to run your fingers through as soon as you rinse it off. It depends on the amount of hair, but if your hair is up to medium length, I think half a packet will do. It would also make a great little thank you gift for a friend.
The scent is similar to Jo Malone's English Pear. I use it once a week as a special treatment and it makes even my hard hair softer, which is great.
It leaves a heavy finish, giving my hair shine and manageability. The scent is nice, but it lingers quite strongly, so you might want to be careful. I think it's convenient to use when traveling.
