I've always had problems with trying to find s decent hair product which give a lasting hold without making my hair clump together and look greasy. I have thick blond hair and used to use a matt clay by V05, however, I always found it made my hair look very greasy, lost it's hold easily and needed constant re-adjusting. I also tried the Matt Separation Wax produced by Tigi Bedhead, however, I found that it lost it's hold in hot temperatures such as on holiday and in clubs, and whenever my hair grew, I had the same problems associated with the VO5. Bumble and Bumble's Sumotech is a miracle, I was surprised to see how small the pot was when I first tried it (especially for the price which some may find 'extortionate), however, it lasted me almost 3 months, and that was with daily use. You only require a tiny amount to be applied to the hair, and I usually apply it on lightly dampened hair then blow-dry into the preferred shape. It gives a very strong hold whist not making it look greasy but giving it an almost shimmering effect (almost Joey Essex style). I have to say that unless they (whoever they may be) make something better, I'm never going to use anything else!
I was sceptical with the product price being double the price of the usual brands (Fudge etc) but this is an amazing product, one that actually lasts a full day. If you have thicker hair like I do, you will understand how frustrating it is when other brands simply 'dry out' in hours and you might as well have not bothered. This product seems like it has solved the perfect balance between strong hold that lasts but is also easily washed out. The best I've discovered yet, would buy it in bulk if they did offers.
Far from cheap, but, as others have remarked, should last a long time. I have fine hair and when used in conjunction with the Bumble & Bumble surf spray I find this product keeps my hair looking good all day.
