I'm quite inexperience with hair dye. Only ever used L'Oréal hair dye in light brown as a result of lockdown and hairdressers closing. Even though it's a light brown colour on the box, it's medium brown. What can I do to lift my hair a little and make it a bit more honey caramel coloured or an actual light brown? Is this only a job for a hairdresser or can I opt for the next shade up. Since dying myself in May 2020, I haven't wanted to pay for it to be dyed at the hairdressers.
