Viewers tuning into Dragons' Den on Thursday evening were left scratching their heads thanks to one woman's business idea.

The latest episode of the BBC show saw Eileen Hutchinson pitch her business plan to Peter Jones, Deborah Meaden, Touker Suleyman, Tej Lalvani and Sara Davies.

As the "head nit-picker" in her family, Eileen claimed that the current products on the market don’t work well enough, so she developed her own.

She pitched her head lice treatment and clinic NitNot, which she believes fills "a big gap in a massive market".

Eileen told the panel her range of products are safe, free from toxic and flammable chemicals and actually work.
