Ultimate Repair Conditioner is a rinse-out deep conditioner from Wella Professionals built around a patented AHA and Omega-9 complex, designed to rebuild strength inside the hair fiber while resealing its outer layer after chemical or heat damage. The creamy formula detangles and smooths in a short leave-on time, so it works into a normal wash routine rather than requiring a separate treatment step.
It's formulated for fine, medium, thick, straight, wavy, curly, and coily hair that is visibly damaged from color, lightening, or styling heat, and is meant to follow Ultimate Repair Shampoo as step two of Wella's repair system rather than replace a leave-in treatment. The conditioner is silicone-containing (amodimethicone) rather than silicone-free, which is what gives it slip and shine, but it is formulated without parabens and is made without animal-derived ingredients.
To use, apply to clean, damp lengths and ends, leave on for 30 seconds to 3 minutes depending on how much repair the hair needs, then rinse thoroughly. Because it's a rinse-out rather than a leave-in, it won't build up over time, but it also won't protect hair between washes the way a leave-in serum would.
