Your hair feels softer after every wash and is easier to comb. That's because the formula works on the keratin level, the building block of your hair. The shampoo replenishes your hair structure with amino acids and peptides, making your hair more flexible and less prone to swell with moisture. That's exactly why it's also suitable for curly hair: you keep your curl shape, but the frizz disappears. The sulphate-free formula cleans thoroughly without drying your hair. Coloured hair won’t suffer. The L'Oréal ProfesSionnel Keratin Alpha Sleek Shampoo Refill Set - 2x500ml is a smart choice if you want to tackle frizzy hair consistently.

Yes, but only with the full Keratin Alpha Sleek routine. Using the shampoo alone already gives you noticeably smoother, shinier hair and less frizz. The 2-week smoothness effect was measured with the complete line, including a leave-in treatment and serum, after four uses.

If you use the shampoo alone, you’ll notice softer hair, more shine, and easier styling after every wash. Adding the rest of the line builds this effect up over weeks.

Yes. The shampoo is suitable for all hair types, from straight to kinky. For curly hair, it tames frizz without losing your curl shape.

Wondering if L'Oreal Keratin Alpha Sleek suits your curls in particular? It depends on what you want to achieve. If you use heat styling, your curls become a bit smoother and looser. If you dry your hair without a blow-dryer or straightener, then your curls stay intact but become calmer and shinier. If you follow the Curly Girl method and avoid Silicones, this shampoo is less suitable because the formula contains Silicones for smoothness.

Yes, exactly the same. The Keratin Alpha Sleek Recharge Refill Shampoo 3500 ml contains the same formula as the 500 ml bottle. The only difference is the packaging and volume.

Feedback on the L'Oréal ProfesSionnel Keratin Alpha Sleek shampoo is consistent: whether you use the small or large packaging, the result is the same. The refill is perfect if you already know the shampoo and just want a big supply without ordering repeatedly.

This set works best if your hair is naturally frizzy, thick or stubborn and you struggle daily to get it smooth. It's also a good choice if your hair swells quickly in humid weather. If you have coloured hair with frizz, it's a mild, safe option.

If your hair is mainly damaged or broken but not frizzy, the Absolut Repair Molecular Complete Set suits you better. That line focuses on repairing hair structure, not smoothness. If you have fine hair with no frizz, this shampoo might feel too heavy. In that case, choose a lighter formula.
