Hi, desperately looking for some help here with what colour to use on my roots. Had my hair lightened 3 weeks ago so I could go a red shade (I was previously a darkish brown). My roots are coming in and are grey/white). I bought koleston perfect 66/46 (hairdresser told me to!) but oh dear far to bright compared to rest of hair. Also not keen on the rest of my hair colour as it's too red and I feel like a beacon. Was hoping for a more subtle brown/red like a mahogany or something. Going to a wedding on Saturday and can't afford to get roots done every 3 weeks so usually do my own in between my 6 weekly visits. I would really appreciate some advice. The hairdresser did use a mix but only wrote down the 66/46 for me to use so have no idea what other colour she used. Thanks in advance
