I've been wearing mascara since early June. Not on my eyelashes, but in my hair, in my parting. It means that I get a few more weeks out of my colour before the hairdressers appointment. My hair is a reddish shade, so a brown-black mascara is perfect. Mascara tends to 'condition' the eyelashes anyway so what harm can it do in my hair? I'll be asking the hairdresser about it tomorrow when I get my colour done.
It was my mum who recommended it as a quick-fix when I went to a wedding. My dad actually exclaimed "oh god, look at your hair!" Thanks for that dad.
But yes, mascara in your hair, when the greys show through.
Genius. Thanks mum!
