Moriah Plath opens up about her alopecia on Welcome to Plathville, detailing hair loss, insecurity, and the emotional moment she shaved her head.

Moriah Plath shared new details about her struggle with alopecia on Welcome to Plathville, saying the condition began in childhood and returned more severely in recent years.

She said her hair fell out within weeks, around the time of her sister Lydia’s wedding, and led to a decision to shave her head.

The moment, carried out by her brother Ethan Plath, became a turning point she described as both painful and necessary.

The update came during a segment of Welcome to Plathville that focused on her health and how it shaped her daily life.

Alopecia, an autoimmune condition, can cause sudden hair loss, and Moriah Plath said she had lived with it in different forms for years.

Moriah Plath said her first experience with alopecia happened when she was a child. She said,
“When I was little, it all fell out.”
As she grew older, the condition returned in smaller ways. She added,
“As I grew up, now and then I’d get little spots, but it was always something I could hide. But I was still carrying some wounds from that.”
In Welcome to Plathville, she explained that the situation changed again later. The hair loss became sudden and harder to manage. She said,

“I was really insecure about it. And around Lydia’s wedding, I just started really falling out like this. Within a few weeks, it was all gone.”
She said she tried to manage it quietly at first. She said,
“I was just wearing whatever I could find to cover my head.”
That approach reached a limit. She told her mother she wanted to shave her head.
“I’m going to have to shave my head.”

Her mother asked who she wanted to help. Moriah Plath chose Ethan. She said,“I told him what was going on. And he was like, ‘Of course.””
She said he shaved her head while she sat through the moment.
“He shaved my head, and I was just sitting there bawling my eyes out.”
She described what came after. She said,
“It was really, really hard at first for a while, but just having Ethan do that, it was just very healing, very sweet. It was what I needed in that moment.”

The episode of Welcome to Plathville also showed her trying to adjust. She looked for wigs and tried to find ways to feel more comfortable in public. The steps were practical, but the change itself took time.
Medical sources describe alopecia as a condition where “the immune system attacks hair follicles and causes hair loss.”

It often appears in patches but can become more extensive. Estimates suggest millions of people in the United States are affected.

Within Welcome to Plathville, Moriah Plath’s account stayed close to her own words.
She spoke about insecurity and how those feelings had stayed with her over time. The show followed her as she dealt with those changes in real time.

This situation showed a different kind of challenge, one that was not tied to relationships or career but to health.
Her family remained part of that process. Ethan’s role in shaving her head stood out because she chose him for that moment.

She described it as something that helped her move forward, even though it was difficult.
The episode did not resolve the condition. Instead, it showed where things stood. Moriah Plath continued to live with alopecia and to adjust as needed.

Welcome to Plathville airs Tuesdays at 10 p.m. ET/PT on TLC and streams after broadcast.
