From pin straight to corkscrew curls, hair is a huge part of us – it protects us from the weather and provides a way for us to communicate who we are.

And what better way to communicate then to get out the hair dye.

Year 12 student Makaela has investigated what hair dye and bleach does to hair, what uncombable hair syndrome is, and why we love dyeing our hair despite the consequences.

Podcast Next Gen is a collaboration between Cosmos Magazine and the National Youth Science Forum.

The reporters are year 12 students from across Australia – the next generation of scientists, science journalists and podcasters. These ‘shortcast’ episodes have been written and recorded by the students, giving them the opportunity to work with real science journalists and editors to make their science concept come to life.
