What it is
Amino Master Deep Repair Hair Treatment is a Japanese rinse-out hair mask, 100g, in a peony and rose scent. Worked into towel-blotted wet hair after shampoo, it deeply repairs damaged, frizz-prone hair with a heat-activated repair ingredient, keratin, and 19 amino acids, then rinses out for stronger-feeling, smoother, glossier hair.
Why it's different
It uses a heat-activated repair ingredient that boosts its effect when you blow-dry or use a hot tool afterward.
Double keratin and 19 amino acids rebuild the feel of thin, weak, damaged hair for more body and shine.
CMC ingredients help restore the internal moisture and nutrient pathways that damage strips away.
How to use
1. After shampooing, squeeze water from the hair thoroughly.
2. Work an appropriate amount through the mid-lengths and ends.
3. Leave it for a few minutes to absorb.
4. Rinse with lukewarm water, then dry, applying heat to boost repair.

Frequently Asked Questions
Is this authentic?
Yes. We only buy from official retailers and directly from the brands here in Japan. Never resellers, never grey market stock.
We are beauty lovers too, so we know the worry, especially with something you are putting on your face. Authenticity is 100% guaranteed by us.
Why should I use heat after applying it?
It contains a heat-activated repair ingredient, so blow-drying or using a hot tool afterward boosts its repairing effect. Squeeze out excess water first so the treatment is not diluted before you apply heat.
Is this a leave-in or rinse-out treatment?
It is a rinse-out mask. Work it through wet hair after shampoo, leave it for a few minutes, then rinse. Drying with heat afterward helps activate the repair ingredient.
Who is it best for?
It targets severe damage, frizz, and hair that has become thin or weak, so it suits hair stressed by bleach, color, or heat. Thick, coarse, hard-to-manage hair benefits most.
How often should I use it?
It works well as a regular treatment after shampooing, and the brand frames a roughly ten-day intensive stretch for a noticeable change. For maintenance, use it several times a week.
