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.

The treatment leaves my hair smooth and silky just by rinsing it off! I usually use a hair quality improvement treatment, but I feel like the smoothness lasts a little longer. The shampoo lathers really well, even on bleached hair. I bought this to treat odors caused by dry scalp after bleaching, but the odor didn't improve. However, the dryness of my scalp may have improved.
My hair is too strong so I don't fully appreciate the benefits lol. I like the scent and feel, which is relatively refreshing. The cost performance may not be great.
I've always had a sticky scalp, but it's gotten a lot better! It lathers well and I like how it doesn't leave any residue on my hair.
I bought this product because I liked the trial version. It leaves a clean scalp. The scent is a bit old-fashioned, I think.
I think this product is suitable for any hair type. However, I thought it was a bit of a hassle to do the three steps on the go.
