La Biosthetique Long Hair Protective Hair Mask 150ml

La Biosthétique’s Long Hair Protective Hair Mask (listed as the Long Hair Protective Repair Mask) is a rinse-off treatment designed to care for longer hair lengths and ends. It aims to strengthen hair’s resistance and help reduce breakage and split ends, while leaving hair feeling smoother, easier to detangle and more manageable. The mask also focuses on rebalancing moisture and improving feel, supporting elasticity, shine and overall smoothness along the hair fibre.

Key technologies and active care components highlighted by La Biosthétique include the “Long Hair active ingredient complex”, glucose polyphenol (described as helping repair damaged structures), wheat bran extract (for protection against deposition of environmental particles/pollutants), and inulin (for moisture support). The brand also references cationic guar for improved combability, plus rapeseed oil glycerides and jojoba/sunflower wax to smooth and help protect against frizz and moisture loss. A clinical study is also cited by La Biosthétique, indicating 80% less hair breakage versus untreated hair.
