touching up roots of highlighted hair

[JudgeLionelNutmeg]

Had my highlights done last Saturday but unfortunately a patch was missed at the front of my parting and I didn't notice before I left the salon.

It's not convenient for me to go back in and get another foil or two done to fix this so is there anything you would recommend I could buy from Boots or similar so I could do it myself?

Thank you

You can buy bleach and peroxide in Boots. Just weave a couple of foils through yourself using kitchen foil.
