As seasoned beauty testers, we've evaluated the latest in-salon hair repair treatments that promise deep repair into the hair cortex, with results lasting up to six weeks. Here's what we discovered.
Pro Fiber (€15), available at L'Oréal Professionnel salons, offers the most customized approach with three versions for low to highly damaged hair. Formulated with Aminosilane to rebuild the cortex and a cationic polymer that targets the most damaged areas, it uses a layered application (shampoo, treatment, mask) for deep penetration. The result? Luscious, shiny, soft hair. Maintain it at home with matching products (€15.50-€27), and recharge every four washes with the concentrated Pro Fiber Re-Charge (€29.90). It's our top pick: affordable, quick (15-20 minutes), and highly effective, especially with home maintenance.
The BB Cream Treatment (from €80) at Myriam K salon (41, avenue de la Grande-Armée, Paris) begins with shampoo and drying, followed by section-by-section application of a deep treatment with macadamia and argan oils plus provitamin B5. It's sealed with a straightening iron to close the cuticles and finished with a shine serum—taking at least an hour. We emerged with glossy hair and ends that looked freshly trimmed. Sustain the effects with BB Cream shampoo (€25) and mask (€38).
The Happiness Treatment (from €90) at Lissfactor salons uses collagen, keratin, silk proteins, and amino acids applied in stages: shampoo and brushing with mask, rinse, second shampoo and two treatments, ending with a final brush to seal the cuticles. It takes two hours, but delivers visibly repaired, smooth, soft hair. Prolong the benefits with Miso range shampoo (€23.50) and Eau de Bonheur leave-in (€27).
