I suspect it’s totally obvious but I’m not getting results with my Superdrug own brand can.. do I use it once my roots start looking ‘tired’? Or is a pre-emptive strike better? Also: how much? And how far away from my head do I position the can?
Someone suggested using it before bed so that it absorbs overnight- has anyone tried this?
I would also love recommendations for brands (both cheap and expensive, I don’t mind paying a lot more if it works and to avoid looking like I’m wearing an 18th century wig
). Please help!!
