Help me complete my quest of dream hair?

Hey fr3ckled  🙂

This may be entirely unhelpful, but I got to a light golden-brown/strawberry blonde by accident. If your hair has any natural red tones (which it should if you're a natural brunette), those should emerge in the bleaching, so you may not have to go to pale yellow then add the colour in. My deep pink hair dye then faded over my warm, golden colour to a definite strawberry blonde, although it's still a little bit pinkish in places. So maybe it's worth trying mixing a bit of pink or red dye with something more neutral (once you're at your desired lightness) to get warmer hints.

I realise that this probably sounds a bit alarming, but it may be worth trying tinting en route to pale yellow to see if you like it!

On the other hand I just looked up your planned colours and those are gorrrgeous, so all I can really say is good luck on your quest, and be sure to wait between bleachings! I look forward to seeing your end results!

I don't think you need to bleach to pale yellow to get strawberry blonde, that's like running up six flights of stairs when you only need to go to the fourth floor.
Try another round of colour remover, maybe a different one than what you've used previously.  From there you might just need to do a bleach bath to lighten to strawberry blonde.  But bleaching past it then dying seems like more effort and damage than necessary.

(note I have only a vague idea of what strawberry blonde is, where I come from it's a euphemism for ginger)
