L’Oréal Professionnel Keratin Alpha Sleek Mask - 250ml

The Keratin Alpha Sleek Mask is the intensive treatment in the L'Oréal Professionnel smoothing regimen. Designed for those who demand more than just surface-level results, this luxurious, high-performance mask penetrates deeply to nourish and discipline even the most unruly, thick, or coarse hair. It works to soften the hair fiber and lock in smoothness, acting as the perfect deep-conditioning step to maintain your sleek, mirror-like finish for up to 10 washes.

Key Benefits

• Intensive Discipline: Delivers high-level control to even the most resistant hair types, significantly reducing unwanted volume and frizz.

• Deep Nourishment: Rehydrates the hair from within, transforming dry, coarse, or over-processed hair into a silky, manageable, and soft texture.

• Prolonged Smoothness: When used as part of the full Keratin Alpha Sleek ritual, this mask reinforces the internal reshaping effects, extending the life of your sleek style for up to 10 washes.

• Weightless Sophistication: Despite its deep-conditioning power, the formula is expertly balanced to ensure your hair retains its natural movement and bounce, never feeling greasy or weighed down.

• Humidity Shield: Strengthens the hair's cuticle to create an effective barrier against humidity, keeping your hair disciplined and frizz-free throughout the day.

The Keratin Alpha Technology

The Keratin Alpha Sleek Mask is infused with the same protein-reshaping science that defines the range:

• Structural Refinement: By nourishing and smoothing the hair's internal structure, it helps to keep the fiber disciplined and straight, making your daily styling routine smoother and significantly faster.

• Fiber Resurfacing: Smoothes the hair cuticle, ensuring that light reflects evenly off every strand for that signature high-gloss, "mirror-sleek" aesthetic.

Simple How to Use

1. Prep: After shampooing with the Keratin Alpha Sleek Shampoo, gently wring excess water from your hair.

2. Apply: Scoop a generous amount and distribute it evenly through the lengths and ends.

3. Deep Treat: Leave on for 3 to 5 minutes. For an extra-nourishing effect on very coarse or dry hair, you can extend the time up to 10 minutes.

4. Rinse: Emulsify with a little water, then rinse thoroughly.

5. Pro Tip: For the ultimate smoothing experience, use a wide-tooth comb to distribute the mask evenly through your hair before letting it sit; this ensures every strand receives the full benefit of the treatment.
