L'Oréal Professionnel - KERATIN ALPHA SLEEK - Serum | 50 ml.

A professional smoothing serum that perfectly finishes your styling, providing spectacular, mirror-like shine and long-lasting frizz control. Thanks to Keratin Alpha-shaper technology and amino acid chains, the product works on the surface and within the hair fiber, smoothing, sealing, and protecting against humidity and heat. The lightweight, leave-in formula doesn't weigh hair down, leaving it soft, shiny, and perfectly tamed.

Key product features:

• Gives hair a mirror-like shine effect
• Provides thermal protection up to 230°C
• Protects against moisture (up to 80%) and prevents frizz
• Smoothes hair and seals its structure
• Provides long-lasting effect – up to 10 washes
• It does not weigh down the hair and makes styling easier.

Active ingredients and their effects:

• Dimethicone (smoothing silicone) – Creates a protective film, adds shine and reduces frizz
• Amodimethicone (conditioning silicone) – Smooths and protects hair from damage
• New generation silicone complex – Seals the hair cuticle and enhances the smoothness effect
• Fragrance composition – Gives an elegant, floral scent

How to use:

After using a mask or smoothing treatment, apply the product to damp, towel-dried hair. Divide hair into sections and spray each section 2-3 times, then comb through to evenly distribute the serum. Do not rinse. To activate, blow-dry or use a straightener.

The result:

Hair becomes perfectly smooth, shiny, and frizz-resistant, even in high humidity. It gains silky softness, thermal protection, and a perfect salon-like finish.

We recommend using it with other products from the L'Oréal Professionnel Keratin Alpha Sleek line – shampoo, treatment and mask – for maximum smoothing effect and long-lasting control over your hairstyle.
