L’Oréal Pro Serie Expert Keratin Alpha Sleek Serum

L’Oréal Pro Serie Expert Keratin Alpha Sleek Serum – Professional Hair Serum for Smooth and Controlled Hair

Transform your hair with the innovation from L'Oréal Pro Serie Expert. The Keratin Alpha Sleek Serum provides lasting smoothness, frizz control, and managed volume for up to 10 washes. Ideal for those seeking disciplined, frizz-free, and heat-protected hair.

Its advanced formula with 5% Keratin Sealer seals the hair structure, ensuring professional results that last up to 2 weeks.

This serum acts as a progressive treatment. With each application, hair gains more frizz and volume control, even in high humidity conditions (up to 80%). Your hair will be smooth, free from unwanted volume, and appear silky and shiny from the very first application.

With heat protection up to 230 ºC, the Keratin Alpha Sleek Serum is perfect for those who use hairdryers and straighteners. Heat activates the serum, allowing hair to become straight more easily and quickly. Styling time will be reduced by half, ensuring an impeccable look in less time.

With 4 applications, you will see the maximum effect: more manageable, disciplined hair with total frizz control. Furthermore, this serum provides lasting nourishment, with visible results for up to 10 washes, and ensures persistent smoothness.
