Anyone with chemically or mechanically damaged hair — bleached, highlighted, permed, relaxed, or repeatedly heat-styled/straightened — of any length, men or women. It's a rinse-out step within a wash routine (not a leave-in), so it suits both salon professionals doing chemical services and consumers maintaining damaged hair at home.

Rehab is aimed specifically at the breakage that comes from double-processing or repeated heat styling rather than being a general conditioner with a "strengthening" claim added on. Because it's built to follow UANS's own Rehab shampoo and rinses out completely, it adds a protein-repair step to an existing wash routine without leaving the weight or residue some leave-in reconstructors do.

After shampooing with UANS Rehab Shampoo (or your regular shampoo), massage the Rehab treatment through clean, towel-dried hair, focusing on mid-lengths and ends. Leave on briefly, then rinse thoroughly. Follow with conditioner or styling products as usual. Sold in sachet, tube, jar, and salon refill sizes.

Pros:

• Rinses out completely rather than building up over repeated use — matters on fine/fragile damaged hair
• Targets a specific damage pattern (bleach/chemical service/heat breakage) rather than being a generic conditioner
• Free of several common irritant classes (parabens, formaldehyde, PABA)

Cons:

• As a rinse-out, doesn't provide ongoing frizz/heat protection through the day like a leave-in would
• UANS hasn't published a full ingredient list beyond "free-from" claims
• Designed to follow the matching Rehab shampoo for best results
