Getting henna out of hair!

[Helenheller]

Hi,

I bought an organic hair dye which promised it would come out after 20 washes. It hasn't!. Is there anyway of getting henna out of hair naturally? I have dark blonde hair normally.

If it's real henna then it's permanent and you will need to grow it out unfortunately.
What's the brand though as it doesn't sound like henna if it's being advertised as a product which will wash out?

It's Radico organic in Auburn. Says it washes out after 30 days.......

It fades if that helps... but you normally have to wait for henna to grow out.

I had a horrible feeling that may be the case. Thanks for your help.
