Anyway, if you like the sound of that do not despair it's no longer on sale because it seems to have been replaced with Intensive Mask for Hair. (£8.16 for 150ml)
But if that costs to much there is always Richly Moisturising Conditioner for Dry Hair which even if you haven't got dry hair (which I really haven't) and only want a treatment, it can easily be used as you would The Intensive Mask.
I know, I've done it and it gives the same results. And at £6.12 for 250ml is better value for money. Especially as you really don't need to use much at any one time.
So there are my favourite treats for my hair, have you any to share?
