Unlock Deep, Lasting Hair Repair: Inside the New In-Salon Treatments

The next generation of in-salon hair care deeply repairs the hair fiber, delivering professional results that last up to six weeks.

As trichology experts know, hair comprises three layers: the cuticle (outer protective envelope), cortex (main shaft), and medulla (inner core). Effective deep repair targets the cortex, requiring ultra-small molecules that penetrate and bond there. This treats hair at its core, where it's most needed, and resists rapid washout.

Yet with weekly shampoos diluting actives, how does the repair endure? "We minimize molecule loss at home with matching shampoos, conditioners, and serums containing the same technology. This recharges the hair, prolonging the salon repair effect dramatically," shares Delphine Courteille, hair care specialist. Water eventually clears all traces after six weeks.
