Highlights - on washed or unwashed hair?

[lucysmam]

I haven't had my hair coloured in so long I can't remember what I used to do

Does it matter?

Thanks

I always wash , not nice for hairdresser to work with manky hair and any product left in hair may make the dye less effective ??

Unwashed. My hairdresser always tells me off for washing my hair before an appt.

And hairdressers don't care if your hair is a bit greasy!

Unwashed.

Right, I'll go with unwashed then! Thanks

Why is unwashed better?

The oils protect your scalp. Colour takes better on "dirty" hair aswell.

Unwashed definitely. The colour will grab better.Obviously you wouldn't go with it greasy and manky hair but washed a day or two before is fine.

Question about hair products in hair specifically dry shampoo .... Yeah or nay?
