What is Edelstein Liss Komplex Treatment?

Edelstein Liss Komplex Treatment is a professional smoothing treatment with keratin, collagen, hyaluronic acid and silk that makes frizzy, unruly and hard-to-manage hair smooth, silky and shiny. Processing time and flat-iron temperature are calibrated on the thickness and condition of the hair, natural, coloured or bleached, for a smooth result tailored to every client. Daily styling becomes quicker, with far less need for the blow-dryer and flat iron between services.

Specifications

Who Edelstein Liss Komplex Treatment is for

• Salons offering a smoothing service calibrated on each hair type.
• Frizzy, unruly and hard-to-manage hair that needs discipline and shine.
• Coloured, bleached or highlighted hair, with shorter processing times and lower flat-iron temperatures.
• Clients who want to spend less time on daily styling.

For a smoothing service with a single processing time, or a rinse-out keratin treatment, see the comparison below.

Key ingredients

• Glyoxylic Acid: the smoothing active that disciplines the fibre and fixes the smooth shape with the heat of the flat iron.
• Hydrolyzed Keratin and Hydrolyzed Collagen: protein derivatives that condition the hair and give it a stronger, fuller feel.
• Sodium Hyaluronate: the salt of hyaluronic acid, a moisture-binding active that keeps the hair supple.
• Hydrolyzed Silk: silk protein for a mirror-like shine and a soft, silky touch.

Results

From the first service the hair is visibly smoother, silkier and more disciplined, with a mirror-like shine and far less visible frizz. It falls fluidly, brushes easily and dries faster, and how long the smooth result lasts depends on the hair type, regrowth and home care with Liss Komplex Hydra.
