She wants to spread a message that empowers individuals to see their inner beauty.
Shelly, a team leader at Future Kids Ōhaupō Preschool, shaved her hair off surrounded by family and friends on Saturday.
She sold raffle tickets, with the prize being to cut off a section of her hair.
The money raised goes to Everybody is a Treasure Charitable Trust, a charity that runs positive body image workshops throughout New Zealand.
Shaving her hair off was a huge act of bravery for Shelly, who had always relied on her hair to feel confident.
"I've never cared what I look like because I've always had hair," Shelly says.
"But when you have no hair it's really obvious — especially as a woman."
"Shaving my hair off meant letting go of that security and choosing to see the beauty inside me. I'm making a statement that beauty is not in your hair — it's in your heart."
"I feel hopeful that this has inspired people to love themselves for who they are inside."
Shelly is documenting her journey on her Facebook page Bald and Beautiful and continues to fundraise for Everybody is a Treasure Charitable Trust on her Givealittle page.
