The beauty spot: flat hairbrushes

Is it still recommended to brush one's hair 100 times before bed? I tried doing it recently and not only did my hair go all static and my arm get slightly achy at the shoulder, but I got bored by the sixth stroke. Brush, brush, brush. It just… goes on a bit, doesn't it? I would much rather tug through a really good, posh hairbrush ( Bumble and Bumble , £49, 0800 014 7424) for a couple of seconds, and spend the long minutes saved doing something more brilliant, like watching video after video of puppies and/or kittens falling over on YouTube.
