About 6 weeks I used a different hairdressers OK a cheaper one like 55 quid cheaper for all over dye as I'm naturally dark and cover grey hair , suddenly lately my scalp has become itchy. It's not my shampoo etc but it didn't feel itchy until weeks later. My old hairdressers costs around 100 with cut and dye but never felt itchy scalp. This was around 6 weeks , you think they used q different dye on my hair at the cheaper one? I need to re do hair but thinking should just pay more now
