How soon after an application can I tint over the top of a client’s brow with a darker henna colour? - 30 Apr 2021

You can apply a darker colour over the top straight away. Elleebana Brow henna is customisable and has a wide spectrum of colours going from Black to a very light Blonde, so you can mix a lot of the colours together, but you can also apply another layer over the top if you feel like you want a darker result.
