WATCH: Real-Life Bearded Lady Isn't Hiding Anymore
Nova Galaxia, from Virginia, said that she started to grow excess body hair - and stopped having periods - as a result of her polycystic ovaries.
On a morning show in the UK, Nova said that she kept her condition from everyone, including her parents.
"It was basically a demon that I had to keep hidden from anyone," she said.
"If I wanted to go to sleepover parties, or go out of town with people, I always had to hide my routine, I had to hide my whole process. If I forgot a razor, I would have a meltdown."
She was diagnosed at 16, when doctors said there wasn't anything she could do and she just had to live with the condition.
Nova has been inspired to quit shaving by British model Harnaam Kaur, and is embracing what she used to hide.
She continued: "It wasn't until I saw a model who has the same condition that I have - I just kind of realised that it's okay, I can be like that too. I can embrace everything that I have and be happy with it. I don't have to hold on to all this misery that I have.
"The first time I went out after I stopped shaving, I kept trying to shift my hair to try and hide my face. I caught myself being obnoxiously self-conscious about it, to the point where my partner was kind of annoyed about it."
