Just for Men Control GX Grey Reducing Shampoo
Our read
Why our pick wins
Neither of us uses PPD, and Control GX goes further — no resorcinol, no peroxide, so it screens gentler than ours. The trade is what it does: it dims grey gradually over weeks and drifts back if you stop. Ours is a permanent oxidative colour that covers and holds, at the cost of a dye system that still needs a patch test.
