Dry Shampoo is the ultimate in convenience when time is at a premium. I don't have a shower so when I struggle to find time for a bath I reach for the dry shampoo. I've tried a number of dry shampoos in the past and Tresemme is by far the best. It has a pleasant scent, though only comes in one variety so the smell can get boring after a while. It comes in a deodorant style canister and has an aerosol spray. I find this much more effective than the mousse shampoos which have little effect at all. Tresemme dry shampoo absorbs grease extremely effectively and while it does not last forever I have often sprayed it on my hair before work and have had it last throughout my working day. It can leave a fine white powder in your hair but this is easily fixed by just running a comb through your locks. Of the dry shampoos available on the market, Tresemme is by far my favourite and is well worth the money, particularly when more expensive products do not work as well as this one.
