More sophisticated version of sun-in - does it exist?

[AgentProvocateur]

I have dark blonde hair that always used to turn lighter in the sun, but doesn't seem to any more.

Is there an adult equivalent of sun in, that won't turn my hair yellow?

TIA

I think there is a John Frieda one. I used to use an Avon one a couple of years ago

It's called Sheer Blonde but I don't know if it's any good.

That was helpful

Mine does this, and this year I've had highlights put in - and I love them. Not a whole head, just where the sun would hit it IYSWIM, so not as expensive as it could have been.

Thank you. I'll look for the John Frieda one first. Was hoping to put off highlights for a few months more...

DD1 uses the John Frieda Go Blonder one. She's quite blond already but it gives a bit of an oomf to normal sun lightening. Also uses the shampoo and conditioner.

I'm tempted to have a squirt myself.
