Wella Ultimate Repair Step 3 Miracle Hair Rescue is a no-rinse spray treatment that helps repair damaged hair in just 90 seconds. This lightweight yet powerful formula works on damp hair to detangle, smooth, and strengthen from the inside out. As a result, hair becomes visibly healthier after just one use. In fact, this formula is enriched with Alpha-Hydroxy Acid (AHA) and Omega-9 to deliver dual-action repair. AHA penetrates deep into the hair cortex, where it helps rebuild internal bonds. Meanwhile, Omega-9 restores the outer layer by sealing the cuticle and reinforcing the hair’s protective barrier. Because of this inside-out approach, the hair becomes up to 12 times smoother and 99% more resistant to breakage. In addition, the hair gains extraordinary shine that lasts up to four washes.
