Totally clueless here. Back in November I dyed my grey hair for the first time in about 25 years. All good, I really liked it, no disasters. But this time I want to go just a shade lighter but I thought it was as simple as just looking at the next shade down but it doesn't seem to work like that. How do I find the next lightest shade? (Clairol Nice and Easy in case it matters).
TIA
