Reparex for Men
After several weeks, the reviewer reported a gradual change in colour. They stressed patience and careful application, and described unwanted copper tones when using other styling products. They also warned that spills can stain skin, fabrics and surfaces.

The reviewer said it worked as described when applied correctly. Their main advice was to wear gloves and remove splashes promptly, because the product can leave brown marks on skin, fabrics and bathroom surfaces.
