Got my hair done nearly 3 weeks ago.
I get my grey roots dyed (she paints it on, waits and then wash and blow)
Literally a week later I see specks of grey coming thru. Now nearly 3 weeks on I can fully seeing them coming thru. Surely it should last longer than this. Am I getting the wrong treatment done? I'm 39 years old brunette and have just grey roots at the top.
Should I change hairdressers or ask for a diff treatment or just box dye because even box dye lasts longer than this
