Formulated For Blondes
Breakage, brassiness, dullness, dryness. We know the needs of blonde hair—and we know how to revive it. Blacklight Blonde Science is for you.
Trusted By Stylists
Originally formulated for the pros, Blacklight Blonde Science was once exclusive to salons and stylists. Today, it’s been refined for all blondes.
Engineered For Results
Researched and developed in our Montréal lab, Blacklight Blonde Science hydrates, repairs, and neutralizes for blonder blondes and healthier hair.
Our story began in Montréal, Canada, in 1986: Chemist Moty Cohen and his wife Liliane began formulating science-proven hair care for the pros, eventually founding Oligo Professionel. But what was once reserved exclusively for salons and stylists has been refined and bottled for us all.
