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.

Since there is no store nearby, I'm happy to be able to try out the sample size before purchasing. No. 40 was the best fit for my hair type, so I'd like to purchase the full size.
I chose La Casta because they have a wide variety of products and I wanted to try out different ones. I have dry, soft, and weak hair, so I bought the 40, but I thought maybe the 35 would have been better for me...? Maybe it's because my hair was too dry. My hair felt rough after washing. I like the scent, but I'm not sure whether to buy the 35 next time, or the 21 since my hair is curly.
It's pretty good. It makes my thin, tangled hair smooth and manageable. I don't even need to use milk after the bath. I usually use a refreshing shampoo, so using this in between is a good rotation. I'm currently growing my hair out, so this is a shampoo treatment I'll definitely keep on hand even when it grows out!
I like the brand Lakasta, so I decided to give it a try.
