I'm completely grey haired and my eye brows have disappeared in my face as they are the same colour. I was watching a Lucy Worsley programme a while back where she said in the past they used cloves to colour their eyebrows, so tonight I gave it a go and actually think it looks ok! You light the bulb bit of the clove, wait for it to cool down and then use it as you would an eye brow pencil - but the effect is actually softer and a better match then a brown or black pencil would be. Has anyone else tried this?
