After lots of good press on here I splashed out and bought my block of Henna Marron and have my gloves, dye brush, clingfilm and shower cap at the ready...
In the shop they recommended that I use the whole block - my hair is just over shoulder length and is super, super thick and I have a fair amount of grey to cover - is the whole block too much?? They also recommended grating it - is this necessary - online it seems ok to just cut up, mix with hot water and then melt over a bain marie?
Any application tips and hints welcome. I am planning on putting it on later, covering in clingfilm, shower cap, putting a towel on my pillow and leaving overnight - is that the best way? I want a strong colour as my hair hasn't been dyed in ages.
All advice welcome!!
