Louise Galvin spent much of her girlhood in her dad's swinging London salon, so she got the scoop on what makes strands behave at a tender age. This early exposure led to two decades of her own work as a colorist to the rich and famous, which culminated in the launch of her Sacred Locks line. The products employ a 'less is more' philosophy, and are sworn to pile on shine, muster luster and eradicate irksome residue. Used in unison, they put your hair at the top of the heap.
