Ashley Tisdale opened up about her experience with alopecia in a new post on her wellness blog Wednesday.

"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," the 37-year-old "High School Musical" alum began her blog post. "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 went on to say that alopecia is a common condition, though many people feel embarrassed to talk about it. The actress noted that her hair loss was due to stress and self-care rituals such as meditation for 5 to 10 minutes would help lower it. She also shared how she became healthier through a 30-day autoimmune paleo diet consisting of vegetables, fruits, fermented fruits, seafood, poultry and herbs.

"Any type of hair loss, from alopecia to postpartum hair loss, can feel surprising — even shocking. When I had alopecia a few years ago, my worries began to spiral; I was scared that it would get much worse. That anxiety only added to my stress cycle. When I focused on the present and accepted what was happening, I was then ready to make a plan to address my hair loss," she shared.

In a video shared on Instagram, the "Scary Movie 5" star talked about her experience with the autoimmune disease. Tisdale said she was in her early 20s when she noticed a bald spot just before the middle of her head and asked her hair colorist and her dermatologist about it.

"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," she said in the clip.

The "Hair" singer also suggested a Platelet-Rich Plasma (PRP) treatment, which she describes as "expensive" and "not the most pleasant experience" but produced "amazingly fast" results for her.

Aside from Tisdale, Jada Pinkett Smith is also vocal about her experience with hair loss.

In a previous TikTok post, the actress said she initially gave in to the pressure of following certain hair trends in Hollywood that "did not feel natural" to her.

"So I had to learn to get the courage to go, 'Nah, I'm not doing that.' Which is why I feel the freedom today," she said. "I don't give two craps what people think of this bald head of mine. Because guess what? I love it."
