L'Oréal Professionnel Keratin Alpha Sleek Shampoo 300ml

Product Description

L’Oréal Professionnel’s Keratin Alpha Sleek Shampoo is a sulfate-free cleanser designed to reshape hair keratin for longer-lasting smoothness. On the L’Oréal Professionnel site, it’s described as gently cleansing while smoothing and reinforcing the hair fibre, helping to soften strands and bring an instant shine with frizz and volume control.

The brand positions it as part of a routine for up to 2 weeks of smoother-looking hair, with results focused on long-lasting anti-frizz discipline and faster daily styling. It’s marketed for all hair types, so it suits anyone wanting sleeker, more manageable lengths without chasing a temporary “just washed” effect.

Key technology is the patented Keratin-Alpha Shaper with amino-acid chains. Notable claims include being sulfate-free (no sulfated surfactants), and it’s also described as free from artificial colourants and alcohol. Lookfantastic and Boots echo the anti-frizz, smoothing and shine benefits, aligning the shampoo with the wider Keratin Alpha Sleek range.
