We’ve seen many “photo-a-day” videos in the last few years, but this video of a girl taking a daily picture of herself for six-and-a-half years is one of the more powerful ones I’ve seen.

The video starts in 2007, when Rebecca Brown was only 14 years old. The video ends just after her 21st birthday in 2014. Watch as she goes from a young teen to a young woman. She struggles along the way with Trichotillomania, a complex condition which makes a person feel compelled to pull out their hair.

This is a pretty drastic change over several years. If you’re interested in learning more about Trichotillomania, Rebecca has a YouTube page devoted solely to info about the condition.
