I believe it is a quality shampoo, concentrated, that lathers, but unfortunately my fine hair becomes like a brush when I rinse it and if I don't use conditioner, it doesn't untangle at all.

Although it does not protect the copper color, I really loved it for the improvement I see in my fine hair. It is now softer, shinier, stronger, voluminous, and hydrated. I use a small amount and delay rinsing it out as much as possible. Afterwards, I use L'Oreal dry oil

Very good shampoo without sulfates for hair with keratin and dyed. With a small amount, it creates a good lather, cleans the hair, and leaves it soft. I use it frequently and I am satisfied.
