I received a single-use sample of the grapefruit scent and used it. I'm very happy because I love grapefruit scents. However, I was disappointed that the scent barely lingers on my hair after rinsing, and although it may just be my imagination, it makes my hair feel a bit rough. As much as I love the scent, I'm not sure if I'll buy it again. Of Cosmetics' shampoos and treatments are all great, so I'd like to find one that suits me.
I love this brand's hair care products and try out various ones. This one has a refreshing grapefruit scent, but compared to me, who normally uses L'Occitane, it's so light it's almost odorless. It's a long-selling product. I learned about it from other people's reviews. The smooth texture is perfect for summer and gentle on the scalp. In the summer, there are more products that cleanse the scalp, but I don't want my hair to dry out, so I thought this was a good product in that regard.
Refreshing citrus scent. I bought this series and am considering which one to buy. The scent is citrus and refreshing, so I think it's good for summer. The scent doesn't linger the next day either.
It has a nice scent! It doesn't lather very well, but that's to be expected since it's an organic shampoo. I wish it was about half the price.
I tried the sample pouch and liked the scent, so I bought the mini size. It has a grapefruit scent. The other sizes are quite expensive. Honestly, when I tried it again, I didn't really feel it was that good, so I'm glad I got the mini size. I think the cleansing power is quite gentle.
