Just for Men Control GX Grey Reducing Shampoo
Our read
Why our pick wins
The gentlest screen of the three — it skips PPD and resorcinol. But it is a gradual reducer: colour dims over weeks and drifts back if you stop. Ours lands on the first wash and holds. How completely it covers depends on how much grey you are working with.
