Amazonliss Unique Step Protein Smoothing Brush is suitable for straight, curly, thin, or medium hair thicknesses. Returns energy and shine to hair, and also significantly reduces curl and fluffiness, at the same time giving hair softness and silkiness. The keratin formula is essentially a "liquid formula" of the hair: it synthesizes pure keratin with the addition of extracts of exotic plants and fruits of the Amazon.

The reducing compounds are very nutritious: they contain a large amount of Brazilian oils and active ingredients for reliable thermal protection. The treatment completely restores the hair, and during the straightening procedure, they acquire a mirror-like smoothness. The keratin care and recovery system also helps prevent tangling of hair and loss of color.

Depending on the type of hair, the effect ranges from three to four months. The duration of the procedure with one-step keratin is on average one hour.
