After the Sliced Bread episode on shampoo, a number of listeners got in touch to request a follow-up episode on conditioners. So of course, we obliged.

Listener Katie wanted to know what they actually do to our hair, if they can deliver on promises for shinier, smoother, or stronger locks – and whether leave-in treatments could be more effective than conditioners you wash off in the shower?

Listener Franziska also got in touch, as she wondered if we could also have a look at heat protection products. She wanted to know what’s in them, can they offer our hair any protection while styling, and is there a difference between the effectiveness of sprays or creams?

Greg Foot rinses out the claims on both, speaking once again to the experts from Shampoo – also available on BBC Sounds.
