You will never see grey hair models in magazines that’s because the companies that advertise in these publications don’t want you to.
I am often asked “can I grow out my hair colour and go grey?”
Yes you can only if you’re 100% white (grey). You see white hair mixed with your natural colour looks ageing but a full head of grey can look very chic. Because grey hair has no pigment and keratin it will frizz and look dry. You need a good shaped haircut (consider a short hair style when going grey), good products and effort to keep it looking styled or it will never work.
Grey hair needs toning otherwise it will start to stain from pollution, smoke, chlorine, etc. A deep violet pigmented shampoo and conditioner will neutralise these unwanted tones or a toner from your hairdresser can do the trick instantly.
My final advice to look fabulously grey is styling. If it is not smoothed out and lacks product it will fuzz. There are a few grey headed clients who I have come across that won’t need to remember all of the above as it naturally looks silvery, white and smooth.
