L'Oréal Professionnel Keratin Alpha Sleek Smooth Transformer 200ml

L'Oréal Professionnel Keratin Alpha Sleek Smooth Transformer 200ml is a professional progressive smoothing treatment designed to transform frizz-prone, unruly hair for longer-lasting smoothness, controlled volume and enhanced shine.

Powered by Keratin-Alpha Shaper technology and Amino-Acid Chains, the treatment works progressively with repeated use to help reshape and smooth the hair fibre while preserving its integrity. L'Oréal Professionnel reports 5X smoother hair, 2X less frizz and +77% instant shine, with the complete routine delivering smoothness, frizz and volume control for up to 2 weeks after repeated applications.

Unlike a traditional hair mask, Smooth Transformer is a heat-activated progressive treatment. Results build with weekly use and peak after four applications, making it the hero transformation step within the Keratin Alpha Sleek routine.

Transform → Smooth → Control Frizz → Control Volume → Enhance Shine

What Is It?

Keratin Alpha Sleek Smooth Transformer is a professional rinse-out smoothing treatment for all hair types, including natural and colour-treated hair.

It is designed for hair that is difficult to control because of frizz, unwanted volume or texture and for customers who want a smoother, more disciplined finish without positioning the product as a permanent straightening treatment.

The formula works progressively: the more consistently it is used, the better the smoothing performance becomes, with peak performance after four weekly applications.

Pair Me With

L'Oréal Professionnel Keratin Alpha Sleek Sulfate-Free Shampoo – cleanses and prepares the hair for the smoothing treatment.

L'Oréal Professionnel Keratin Alpha Sleek Mirror Sleek Serum – completes the routine after rinsing Smooth Transformer and provides the finishing smoothing and protective step.

The recommended intensive routine is:

Sulfate-Free Shampoo → Smooth Transformer → Mirror Sleek Serum → Blow-Dry / Heat Activation

On other wash days, replace Smooth Transformer with the Keratin Alpha Sleek Professional Hair Mask:

Sulfate-Free Shampoo → Professional Hair Mask → Mirror Sleek Serum

The Mask and Smooth Transformer are therefore alternating treatments, rather than products that need to be layered together during the same wash.
