Easy to use
It's handy if you're in a hurry 👍.. mix the 2 solutions in a separate plastic bowl ( anything which u won't use again) and then apply to the hair. And if you have gray hair please keep it on for minimum 20-25 mins(on the instructions it says 10mins) I am giving 4 stars as I found the quantity very little (i have short hair)
