I'm considering dying my hair at home, rather than paying upwards of £50 to have a permanent hair colour done at the hairdressers. The reviews of the Caca henna on Lush's website look positive, and it's only £8 a block, but they say that you have to grate up the henna and add water to kae the dye, and then leave it on for 4 hours before washing it out - I have a 2 year old so don't have many 4-hour blocks to myself!
My hairdresser says that she wouldn't recommend anyone dying their hair at home (but she would say that wouldn't she?) and that she has a customer who hennas her hair because she's allergic to proper hair dye, and it doesn't cover grey. The Lush reviews say that it does cover grey, so I'm really confused.
If you've used the Lush henna, does it really take 4 hours to work, and does it cover quite a bit of grey? Would you recommend it? If it does take 4 hours, is it really messy / dripping or can you just carry on life?
