I love that hairstyle!
OP I am giving the grey hair another go after quite a few attempts. I have tried the head shave and wearing scarves/hats thing but dyed it again ( it was the style I didn't like rather than the grey as I quickly discovered). Whenever I see women with short groovy grey haircuts - I think they look wonderful - ESP if they have red lipstick and bold jewellery. It doesn't have to look like you've given up.
I have really resistant grey hair which will probably look great when grown out but that process is, let's be honest, grim. Mine isn't all over either so I struggle with that.
There are several ways of doing it. Some people do bleach and have it toned grey. The problem with this is it doesn't stay true for long before it looks brassy. Others opt for highlights they tone ash and gradually have less and less put in so it is a more prolonged but subtle transition. This is expensive and again can be irksome in terms of keeping the brass at bay.
Another way is to buy a touch up pen (such as Roux) and keep doing that until you have enough to pixie. After eight weeks you will have an inch to work with and by 12 weeks -one and a half on average.
Some people opt for a wig and others if they have long hair tie chiffon scarfs around the badger and work a 1950's vibe.
Others just brazen it out. It is harder though if you have naturally dark hair but usually the silver that comes in is more stunning.
There are sites that offer support. One of them is 'going gray guide' on Facebook and they post loads of photos of people transitioning or that have transitioned. There is also 'cafe gray' but that is a wee bit American Christian 'mom' in places so if you can get past that vibe it is a great resource for advice. Some of the women on there have blogs too.
The Highland Fashionista is out there with her grey hair and really works it as does the woman from 'how bourgeois' blog.
I think it really helps if people don't bang on about you being too young to go grey. Nobody in my circle gets it but then none of them went grey at sixteen and has been dyeing their hair every two weeks to keep on top of the roots. I am not yet forty and role models are slim on the ground.
