I have to share with you my brilliant discovery. To be honest, I have used these little gems before, but this time round, I used it on DRY hair.
Their smallish bottles of wash in/wash out 'colour enhancers' - supposedly used in place of conditioner. On the bottle it says to wash hair, then massage in, leave for 5 mins & rinse or for a more intense result, use on dry hair. I did exactly that, although left it for an hour.
My hair was a meh warm brown before. I used Light Strawberry Blonde & it's now a gorgeous copper colour. It's really brightened (and lightened in places) my hair, it shines lovely & in the sunshine my hair looks such a lovely colour.
I think they come in a range of colours from cool blonde to mahogany for brunettes. Costs £1.49 a bottle (on offer at the moment at £1.29).
I've been in and purchased another 2 bottles, hoping they don't run out of stock!
