I bought this product because it was a hot topic on social media! I have virgin hair and an oily scalp. It was said to leave a smooth finish, but I felt it was a little lacking for me.
I bought this after seeing positive reviews on social media. My hair was getting a bit dry and frizzy due to excessive use of hair care and styling products, so I've been using it twice a week as a reset shampoo. It seems to have removed all the residual hair oil, making my hair feel lighter and smoother to the touch, so I plan to continue using it.
It's fragrance-free, gentle on the skin, yet smooth! Perfect for morning sickness! I started using this shampoo after my head got a rash when I was using another shampoo. I used a different shampoo for a while after that, but then I got pregnant and started having morning sickness. I can't stand scented shampoos, and I feel nauseous every day while bathing, so I asked my husband to buy me this. As a result, since it's fragrance-free, it didn't make me feel nauseous, and it was really good! I recommend the treatment, as it leaves my hair feeling smooth, rivaling even the best shampoos. There's less treatment than shampoo, so be careful when using them together.

I bought the COW Brand Shampoo SB refill (360ml). It's a mild, additive-free formula for delicate skin, leaving your scalp feeling refreshed and your hair feeling silky smooth. It's a mildly acidic shampoo formulated with naturally derived amino acid cleansing ingredients for your scalp. It contains naturally derived conditioning ingredients, a silicone-free formula, and skin-derived moisturizing ingredients: ceramide, hyaluronic acid, and amino acids (glycine). [Usage of shampoo alone] It produces a fine, fluffy lather. It's not dense. I don't think it lathers particularly well. It doesn't leave a rough feeling after rinsing, but it's not slippery or soft. It feels smooth and manageable after blow-drying. It doesn't leave hair in the hair the next morning, and it's a little dry. I think it leaves my scalp feeling refreshed. It's fragrance-free, but it has a refreshing scent. I'd like to try the moisturizing version.
