This remarkable time-lapse video shows a woman's battle with hair-pulling condition trichotillomania.
Rebecca Brown, now 21, took a selfie a day for six and a half years and has made the photos into a video.
She has trichotillomania, a condition that causes people to pick and pull at the hair on their scalp, eyebrows, eyelashes and elsewhere on the body.
Rebecca also suffers with dermatillomania, which is known as compulsive skin picking.
Writing on her YouYube channel, Rebecca said: "Watching this back is rather scary for me, it makes me both sad and happy at the same time.
"I'm not an exceptionally happy person and don't pretend to be. What I will say is, that when you see the smiles in this, especially after the baldness happens ... those smiles are genuine.
Story continues after the video
"Beauty is more than what we see with the eyes. People are more than their conditions. I am more than my hair and skin."
During the four minute video, Rebecca is seen with long flowing locks, and bald patches of scalp. She also wears a wig and appears with a shaved head.
Rebecca runs two YouTube accounts - a personal channel and one that offers support for others with Trichotillomania.
