Behind the scenes of the hair extension industry, and stopping the cowboy builders

Available for over a year

Ever wondered where the hair in hair extensions comes from? Or how much cash you could get for your own hair? We look behind the scenes in the world of hair extensions. What are the risks? What are the different types? Is the demand for hair extensions putting up the price of wigs on the NHS? New pro-biotic formula baby milk is being sold in the UK which tells parents to make up the formula at lower temperatures than government guidelines. Is it safe? We find out. And - if you want to hire a builder for your home extension, it's time to stop dreaming and start being more hard-headed. We have advice on how not to be ripped off by rogue builders.
