Ingredients
How to use
Step 1: After shampooing, thoroughly squeeze out excess water from your hair. Step 2: Apply to the entire hair, massaging it in thoroughly, especially in the mid-lengths and ends, where moisture tends to be lacking. Step 3: Leave on for 2-3 minutes, then rinse thoroughly, making sure not to leave any residue behind. If you are concerned about hair damage, comb your hair using a head spa bath time brush and leave it on for 3-5 minutes, which will allow the hair mask to adhere to each strand of hair and enhance the treatment effect. Then rinse thoroughly.

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.
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 bought a sample size and am trying out which one is best for my hair type. After rinsing, my hair doesn't get tangled or rough, and it smells nice. La Casta has a wide variety of products, so being able to try the sample size before purchasing the full size is very convenient, especially since there aren't any stores nearby.
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'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.
