What it is
“Isshi”已向“卷发”这个强大的敌人发起反击。对于那些仍然依赖沙龙拉直、酸性热护理和早晨用直板夹来对抗毛躁和波浪卷发的人来说，你们牺牲了很多：头发损伤、沙龙消费以及宝贵的早晨准备时间。ISSHI 护发精华液是“卷发修复”的理想之选，无需牺牲这些。这款护发精华液含有乙醛酸，这种成分也常用于美发沙龙流行的酸性热护理中，但它使用方便，适合在家使用。每日护理，即可由内而外赋予秀发弹性和强韧度，修复损伤，令秀发更易于打理。在家轻松进行酸性热护理。

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.
I get my hair straightened every 8-10 months, and when my hair grows out and starts to get wavy, I use this! It's great because it keeps the waves and frizz down.
I'm worried about the smell, which is similar to that of coloring agents.
I bought a single-use pouch to try out. I was curious about the smell, but there was no unpleasant odor at all. I figured I wouldn't notice it after just one use, but my hair was noticeably smoother after using the hair dryer. I'd like to buy it again this season when dryness is a concern.
The finish is light. It doesn't completely eliminate frizz, but I found it to be easier to manage the next morning.
I tried the single size for the first time. My hair is wavy, has split ends, breakage, is dry, and unmanageable, but I just used a hair dryer and it's smoother than usual. However, there are still some areas of my hair that remain wet no matter how long I use the hair dryer, and there was no improvement in those areas. I'll decide whether to repurchase depending on how long this smoothness lasts.
