  Buying shampoo can be overwhelming – there are so many brands to choose from, across a huge range of prices. Some brands promise to repair and nourish our hair, while others promise to strengthen and add volume. But are any of these claims true? Do we even need shampoo at all?
  Since long before shampoo was invented – some say in India – our bodies have been producing sebum – an oil-like substance. Sebum stops our skin from getting dry, manages the health of our scalp and makes our hair shiny. But it also collects dirt, and, if left untouched for too long, sebum can cause our hair to become greasy1. There are no disadvantages from a health perspective to letting our hair be greasy, says Eleanore Richardson, Trichologist at Fulham Scalp and Hair Clinic, but many people choose to wash their hair regularly for aesthetic2 reasons.
  And so we reach for the shampoo bottle. Shampoos contain a group of chemicals called surfactants. They grab the dirt and grease from the surface of our hair, meaning when we rinse3 away the shampoo, we also wash away the grease and dirt. But, as Laura Waters, who's a Professor of Pharmaceutical4 Analysis in the School of Applied5 Sciences at Huddersfield University, points out, 'some surfactants work too well' and take the natural oils out of the hair, as well. More expensive shampoos may contain less harsh surfactants, but – adds Laura Waters – the type of shampoo doesn't really matter. 'It's on our hair very briefly6 and gets washed away'. It's the conditioners and styling products that we use after the shampoo that make a bigger difference to the texture7 and feel of our hair.
  Of course, the more we put onto our hair, the more we need to cleanse8 it off, creating a vicious circle. So, yes, it seems we do have a need for shampoo, but we also shouldn't expect it to be a miracle cure. And, finally, next time you're in a shampoo aisle9, remember that hair is made up of dead protein cells and that, sadly, not even the most expensive shampoo can bring them back to life.
