Update: two days since I dyed my hair and the warm and yellow tone in the roots has almost disappeared now and become more neutral. So happy about that. However, my hair became incredibly static after I dyed it. And it has continued even after I washed my hair.
Used 10.0 on bleached light blonde hair with roots and yellowed areas. Got a slightly warm and yellow shade on my roots but not too bad, and I think it turned out to be a nice and even tone throughout the hair. And the hair feels both soft and healthy after, unlike when I usually use hair dye with ammonia. It stung a little on the scalp at first, but that went away and I feel no discomfort afterwards. Next time I will try 10-19 as I probably want a slightly cooler blonde shade.
