Quick! Recommend me the BEST home hair lightening product Please!

[youvegottobekidding]

I can't sit on my hands any longer! I have to take the plunge & do something with my hair! Whilst I'm feeling brave (or stupid) I'm looking on Boots & have seen these-

I have at the moment coloured (shoulder length) mid reddish brown hair, reasonably ok condition. I want it lighten it a couple of shades. Reduce the redness if possible. I do have a semi mid ash blond waiting as a back up.

Just to clarify, I don't want to be blonde, just a lighter brown, either golden or neutral. Would any of these lift my hair? I've tried colour removers a couple of months ago but they re-oxidised.

Update for anyone whose interested!

Chose the Schwarzkopf one. Saturated hair except roots as they are lighter anyway. Left for 45 mins. Looked nice whilst developing. Results wasn't far off canary yellow 😳. Luckily had a mid ash blonde semi in cupboard so slapped that on. Toned it down to a less offensive light brown/blonde with a slight yellow tone. Have got some of the L'Oréal elvive purple shampoo so will use that the help with the yellowness. Surprisingly hair feels lovely and had no fallout, still in reasonably ok condition. Suspect may need a toner of some sort in a week or two when this semi starts washing up. Don't fancy the canary look. Frightened my ds!

Before and after pics?

Not great but this is the back, inside under lighting. It was just a mid reddish coppery brown before. Looks a bit gingery this morning. At least it's not alarmingly yellow I suppose. Hopefully the purple shampoo I got will help tone it a bit more.
