This can be tricky. Grey hair represents changes in our bodies. It’s totally natural for oil glands to slow down their production of sebum (our hair’s natural moisturizer) as we get older. Gray hair is difficult to tint because it tends to be more dry and brittle, which means that the dye takes a lot longer to penetrate them. We of course encourage you to try but we’ve had clients with varying results. We can recommend trying WHAT THE BROW serum to nourish the brow hair,  to support and repair during the colouring process.
