My mum bought for my birthday in March, I am not sure where but you can buy 250 mls from www.feelunique.com for £18.70 or 125 mls from www.johnlewis.com for £13.20
I had read some reviews before I started using the product which said it left their hair dry and a bit like hay. I did find that this was the case if you used too much of the product. With all Philip Kingsley products I do find that you need a lot less of the product than with other brands.
I was quite disappointed in the product I found that when I was blow drying my hair it had lots of volume and bounce but as soon as I brushed or smoothed my hair it was all gone. I also found that my hair wasn't as smooth or manageable. I also would have preferred a product which included some heat defence as most drugstore volumisers do.
I doubt very much that I would purchase this again as I think that a cheaper drugstore volumiser would be much better value for money.
