MODAMODA Pro Change Black Shampoo
Our read
Why our pick wins
A no-PPD progressive darkener that relies on THB, with no coupler set and no developer — so it screens gentler than ours. What it cannot do is arrive: the tone deepens over weeks. Ours colours the first time you use it, and how completely depends on how much grey you have.
