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've used the oil and it was great, so I bought this one. It's lighter than the oil, but the scent is nice and it gives my hair a moist, shiny finish even after ironing.
I've used up the mini size. I got it at the store. The Repair Acid Heat Treatment Serum is said to restore hair to a healthy, slightly acidic state, leading to a moisturized, smooth, and shiny texture. I don't really notice much improvement when drying my hair with a hair dryer, except that it's easier to manage. The color really makes an impact. I'll consider buying it if I have the chance.
I bought this on the recommendation of the store staff and it's a repeat purchase, but I also found it available here so I decided to buy it. My hair is rough, but it keeps it manageable and moisturized, and it's great for blow-drying.
I compared the products at the store before purchasing this. I highly recommend this for those with frizzy or wavy hair! It keeps my hair in place very well.
I received a gift from someone I met at work. First of all, I love the smell. (It reminds me of a woman coming back from the hair salon.) My hair feels smoother than usual after drying with a hair dryer.
