I bought this just to keep my gray hair dye in place. I've tried a few other products, but this one has stuck with me for now. It seems to be less likely to come off. The conditioner is a bit pricey, but it's a good product.
My hair was pretty damaged from repeatedly using high-tone hair, so I tried this for the first time. It lathers well, I like the scent, and it leaves my hair feeling moisturized and smooth after washing. Even after drying, my hair didn't feel particularly dry or rough, it was moisturized and not particularly tangled. It doesn't get frizzy in the morning, and even with high-tone hair, it feels shiny! I'll be using it again for a while!!
The shampoo lathers well and is easy to wash off. The scent isn't too strong. The hair mask left my hair feeling a bit sticky after washing. Maybe that's what moisturizes it, but I don't really like it. It feels a bit heavy. I have a lot of hair, so maybe that's why it felt that way.
I love it. I bought the pouch for travel. The scent isn't too strong and it lathers well. The pouch has a large amount, so I used it twice. My skin felt moisturized after washing.
If you like Predia, please try it. It leaves your hair feeling fresh and smooth (^^)
