Every sleek-hair routine has to start somewhere, and jumping straight to styling is like painting over a wall you never cleaned. This sulphate-free shampoo is the prep step that gets your hair genuinely smooth before anything else touches it.

TL;DR: A sulphate-free professional shampoo from L'Oréal Professionnel with an ultra-creamy texture, powered by Keratin-Alpha Shaper and amino-acid chains. It gently cleanses while smoothing and reinforcing the hair's keratin for softer, shinier, frizz-controlled hair. Suitable for all hair types, alcohol-free and artificial colourant-free.

Product Details and Benefits

• Formulated with Keratin-Alpha Shaper and amino-acid chains that reshape and reinforce the hair's keratin at the fibre level as it cleanses.
• Sulphate-free, ultra-creamy formula that cleanses gently without stripping, so hair feels soft and hydrated rather than squeaky.
• Delivers instant shine and visible frizz and volume control from the very first wash.
• The cleansing first step of the Keratin Alpha Sleek system: used as part of the full routine, it helps transform hair for 2 weeks of smooth, frizz and volume control*.
• Suitable for all hair types. Alcohol-free and artificial colourant-free.
• 300ml.

How to Use

1. Massage the creamy formula through wet hair and work up a rich lather.
2. Rinse thoroughly.
3. On your weekly wash, follow with the Keratin Alpha Sleek Smooth Transformer; on other wash days, reach for the Keratin Alpha Sleek Mask instead.

Pro Tip: Sulphate-free formulas lather more gently than you might expect — that's the design, not a shortfall. On your first wash after a week of styling products, do a quick double-cleanse: the first lather lifts the buildup, and the second lets the smoothing formula actually get to work on clean hair.

Why You'll Love It

Great smoothing starts with a clean slate, and this is the shampoo that lays the groundwork for every glossy, frizz-free day that follows. Add it to your cart and give your sleek routine the foundation it deserves.

*The 2 weeks of smooth, frizz and volume control reflect the full Keratin Alpha Sleek routine (Shampoo + Smooth Transformer + Serum) after 4 applications, as published by L'Oréal Professionnel (lorealprofessionnel.com), not the shampoo used on its own.
