Gallery: Stylist Spends 13 Hours Transforming Depressed Teen's Matted Hair

In an August 2017 Facebook post, hair stylist Kayley Olsson described an encounter with a 16-year-old girl that left both of them dramatically changed.

Olsson was working in an Ohio hair salon when the client, who remains anonymous, walked in with severely matted hair. The client had been battling depression for several years, and it had progressed to the point where she could no longer even brush her hair.

The teen was preparing to head back to school in a couple weeks and was just a day away from having her school picture taken. When she walked into the salon, the teen called herself "worthless" and told Olsson to "just cut it all off."

Olsson, however, was not about to do that.

Instead, she spent 13 hours transforming the teen's hair. In an encounter that proves that a little kindness can go a very, very long way, she documented the transformation and shared the photos online, where they quickly — and understandably — went viral.
