The products are manufactured without the addition of colorings, perfumes, and thickening ingredients since their origin (1978), because the very high quality of raw materials we use allows us to avoid any kind of covering.

The products have been tested and deemed "Incapable of causing irritation or allergic reactions”. So the shampoos and treatments are 100% safe.

The products are made without formaldehyde since the origin (1978). Formaldehyde is a preservative considered to be very dangerous, although widely used for its low price.
