"Was just diagnosed with alopecia in the midst of a major depressive episode," she wrote over the clip.

Writing the hashtags #alopecia and #mentalhealth in the caption, she added, "Red light therapy is my new best friend."

According to the National Institutes of Health, alopecia is "a disease that happens when the immune system attacks hair follicles and causes hair loss."

"Hair typically falls out in small, round patches about the size of a quarter, but in some cases, hair loss is more extensive," it said, adding that it usually affects the head and face.

The NIH said this condition has no cure, though "there are treatments that help hair grow back more quickly," including red light therapy and steroids.

Even before her alopecia diagnosis, Reinhart has been vocal about her struggles with anxiety and depression. In a 2020 interview with Refinery29, she said she reached the point of feeling stuck in a "black tunnel [that] was never going to end."

"I couldn't see the light. I was like, 'I feel like I'm dying.' It was f—king rough, and there's no other way through it than just through it," she shared at the time.

Reinhart said she decided to face all of it head-on. "I've seen a lot of people when it comes to heartache and grief and breakups, and they try to get that void filled with sex, with coke, with food, with drinking, [but] the void is still there. I took the road less traveled and just dealt with my s—. I had to face my own pain head-on," she continued.
