Rebecca Brown, otherwise known as BeckieO on YouTube, took a photo of herself every day for six and a half years. The result is surprisingly sweet - watching yourself age is a strange and surreal experience.
The twist in the video comes at the very end, when Rebecca describes her battle with trichotillomania - a disorder where she has the urge to pull out all her hair, strand by strand. It sounds like it belongs in a horror movie, but it's a real problem faced by thousands, according to Trich.org.
