Hair lightening product that’s not a bleach/dye?

[Skittlesandbeer]

Hiya, my family are all dark brunettes, other than DD (9). I’d call her hair honey-coloured? It goes quite blond in summer. In my country it’s spring now.

She’s got a school concert coming up in a few weeks, and needs to wear a blond wig (which she hates). Have negotiated with the organiser that if her hair is a couple of shades lighter, she can ditch the wig.

I’m wondering if anyone’s heard of a safe and gentle way to encourage hair slightly blonder? I’m against strong chemicals on kids, and also don’t want it dramatically/obviously lighter afterwards for school. It will be sunny here during the concert lead-up, but not probably enough to change it the 2 shades we need.

Any ideas? I’m quite at sea when it comes to light-coloured hair!

Take her to a hairdresser, look for one that uses Olaplex & ask about high lift tint, they aren't as harsh as bleach but still lift the colour lighter.

How about a spray colour or hair mascara?
They would wash out.

Lemon juice plus sunshine might work but no guarantees
