Jaquie Brown's 3-year-old son says his Mum looks like a "beautiful hedgehog" now that she has shaved her head.

The comedian got the chop for charity, raising more than $5400 for the Cancer Society. And she says she's thrilled to have achieved more than her fundraising goal of $5000.

"I'm taking it as a sign that people have kind hearts and wanted to support the Cancer Society, rather than them harbouring a secret hate of my hair."

The Jaquie Brown Diaries star lost her father to cancer when she was in her 20s and her mother is a breast cancer survivor.
