Costly shampoos not head above rest
The magazine picked 22 shampoo brands to assess how well they prevented dyed hair from fading, or how well they treated dry and damaged hair. The survey found cheap makes of shampoo were often as effective or better than many of the best-selling products on the market.
In tests, a supermarket own-brand shampoo priced at just 99c scored highly while a make used widely in hairdressers, and costing 14.50, performed badly.
