Ashley Tisdale suffers from alopecia

Los Angeles: Actress Ashley Tisdale has been losing patches of hair because of autoimmune disease alopecia.

The ‘High School Musical’ actress has found over the years that her hair starts falling when the autoimmune condition flares up during times of stress, most recently when moving house and starting a new job, reports femalefirst.co.uk.

She wrote on Instagram: “Alopecia and hair loss are fairly common, but a lot of people feel embarrassed to talk about these issues. Any type of hair loss can affect your self-esteem, especially if you feel like you’re the only one going through it.”

“That’s why I want to talk about it openly, because it’s nothing to be ashamed of.”

“Sometimes it’s connected to hormones, other times to heredity, and for me, it’s connected to stress overload. Today on @frenshe I’m sharing what I’ve learned about my alopecia and how I help manage it.”

On the website for her Frenshe skincare, the 37-year-old star who has 21-month-old daughter Jupiter with husband Christopher French, went into more detail about what had happened a few months ago.

She explained: “A couple of months ago, while simultaneously moving, starting a home renovation, and kicking off a TV project, I noticed that a patch of my hair was starting to fall out.”

“Nothing major – just a small section behind my ear – but still, it was happening, and not for the first time. A few years ago, the same thing happened when I was overly stressed, so I knew exactly what I was experiencing: alopecia.”

Tisdale finds her hair eventually grows back and she tries to tackle it with yoga, meditation and therapy.
