how do I deal with eyebrows going grey

Trim any hairs that are growing too long, and dye any that are white rather than pluck them out.
I use a product called Demure Color Gel, in brown, from Amazon. It's easy to use and gives a good result.

Mine are a mix of black and white so I pull out the white ones which are much longer than the others, then use a pencil.

I dye them at home. My head hair is still dark, so it looks really odd to have grey eyebrows, and what with the barbed-wire hairs growing - so I trim and dye.

When my head hair goes properly grey I’ll let my eyebrows match! But still trim them to avoid the Denis Healey effect…

I find I look better with grey eyebrows than if I try to colour them.

I use Dye brow, you can get it from Boots or Amazon. Costs about £5 . Very easy to use if you follow instructions. Different shades available. I’m blonde, but use dark brown. Leave on for 6 minutes.

I just use an eyebrow pencil.
