Well we know emojis are all the rage these days, so much easier to convey messages and definitely handy for the Twitter character limit.
There have been 4 emojis submitted for the 2018 roll out that is reflective of all different types of hair style and colours and could be added to your emoji keyboard. There has been white hair, curly hair (or Afro) and bald hairs.
At a conference held at Apple there were discussions to have a standalone redhead character but it was later concluded that there would be white hair, curly and bald cuts to be added in. UNFORTUNATELY, if you're an alternative, blue/pink coloured, reverse mohawk type of person then you may have to wait a little bit longer to get your own.
