Not go to the hairdresser obviously. I mean how are you going to deal with your hair at home in the long term? It could be months before hairdressers can open again.
Mine is cut and coloured fairly regularly and it's quite a 'style' that can't be dealt with by a trim at home by DH or something. Roots starting to come through, have never home dyed so no idea where to start!
It's not the end of the world obviously but I'm NHS and going to work everyday so I need some sort of plan. I was very ill last year and couldn't leave the house for nearly 3 months and my hair was rancid which just amplified my general feeling of misery so I'm keen not to feel like that again if I can help it!
