Ingredients
How to use
Step 1: Pre-wash with lukewarm water before applying the shampoo. Lightly remove dirt, dust, styling products, etc. from your hair and scalp, and thoroughly wet your hair to prevent friction between strands. Step 2: Take an amount about the size of a 500 yen coin* in your hand, spread it in your palm, and lather lightly, then spread it over your entire hair. Use the pads of your fingers to incorporate air into the lather, then gently envelop your hair as you wash. It is important to lather generously to prevent friction on your hair, which can cause damage. With a focus on the lifting effect, shampoo while massaging in zigzag motions, lifting your scalp. Massage with your fingers in circular and zigzag motions. *Adjust the amount according to the level of dirt, length, and volume of your hair. If any shampoo remains, it can cause dandruff and itching, so avoid shampooing.

I like how it makes my hair smooth. It's a little too light for my hair in the fall and winter, so I think it's better suited for spring and summer.
I have short, fine hair. I tried the sample and liked it so much that I decided to buy it. It makes my hair incredibly smooth and shiny! The treatment was heavier than I expected, but it seems like it's perfect when your hair is dry.
I usually use #35, but this time I used #21. All of the La Casta products are great and there are no misses. The freedom to mix and match is also appealing. Please give it a try.
I've used several La Casta products, but this one is the best for me right now. I would recommend 21 to anyone who has trouble with tangled hair.
It lathers well and I like the herbal scent. My hair had become very hard to run my fingers through due to the shampoo I used before, but with each use, it has become smoother and shinier. You don't immediately notice the benefits, but it feels like the effects come on gradually. I bought the two-week trial size again because it was so good. I have straight hair and it's not very damaged, so the size 21 was just right. If you have damaged or dry hair, it may not be enough for you.
