All our professional frizz control smoothing products

All you need to know about frizz control & smoothing.

• What causes frizz and unruly hair?

  Frizz occurs when the hair's outer layer, the cuticle, is raised, allowing moisture from the air to enter and swell the hair strands. This process leads to a rough, uneven texture and a "frizzy" appearance. Several factors contribute to this:
  Humidity: The most common culprit. When the air is humid, hair absorbs moisture, causing the cuticles to swell and lift.
  Lack of Moisture: Dry or dehydrated hair will actively seek moisture from the atmosphere, making it more prone to frizz.
  Hair Damage: Damage from heat styling, chemical treatments, pollution, or even harsh brushing can compromise the hair's cuticle, making it rougher and more susceptible to frizz.
  Hair Type: Naturally curly or wavy hair often has a more open cuticle structure, making it inherently more prone to frizz.
  Understanding these causes is the first step toward achieving smooth, frizz-controlled hair.

• What's the difference between L'Oréal Professionnel's Liss Unlimited and Keratin Alpha Sleek ranges for frizz control and smoothing?

  L'Oréal Professionnel offers distinct ranges to address frizz and unruly hair, each with unique mechanisms and benefits:
  L'Oréal Professionnel Liss Unlimited: This range is expertly formulated for immediate and intense smoothing, primarily targeting the hair's surface and providing robust humidity protection.
  L'Oréal Professionnel Keratin Alpha Sleek, featuring Smooth Transformer: This revolutionary range offers a deeper, more transformative, and progressive smoothing solution.
  

• Is the Keratin Alpha Sleek range suitable for all hair types, including colored or chemically treated hair?

  Yes, the Keratin Alpha Sleek range, including the Smooth Transformer, is designed to be suitable for all hair types seeking frizz control and smoothness. This includes hair that has been colored or chemically treated. The formulation is crafted to provide smoothing benefits without compromising hair strength or integrity. The Smooth Transformer can even be used the same day as your color treatment. We always recommend following the usage instructions carefully for the best and safest results across all hair types.

• Does Keratin Alpha Sleek range contain keratin? ​

  Keratin is an animal-derived ingredient, also found in human hair. These products don’t contain keratin, but reprogram hair from deep inside the fiber at Keratin Alpha level, reshaping Keratin Alpha chains for 2 weeks of smooth, frizz-controlled hair. *
