So, usually after i've done my roots i tone them with just a purple shampoo and i mean it works but it does leave some very purple bits which i hate, but this toner is actually blue based and i definitely prefer a blue base toner.
You can find this toner at Savers and it's ridiculously cheap too! like £4 i think!
How i applied Shades London Toner:
Firstly, wet your hair, i just quickly put in some conditioner and rinsed it out. Then starting with the roots section so you reach each part of your hair then apply to ends and massage all the product into the hair. Leave on for 10-15 mins. Wash out and done!
You can also leave it on longer for a more darker grey!
And thats it! hope you found this helpful, do let me know if you have any other questions!
