Ever since revealing her multiple sclerosis (MS) diagnosis, Selma Blair has been open and honest about what it's like to live with the debilitating neurologic disease. (Did you know that doctors didn't take her symptoms seriously before her official diagnosis?)

From using her cane at the Vanity Fair Oscars After Party to sharing how challenging simple things like doing your makeup can be, the actress has been doing her part in bringing awareness to the MS community.

Now, Blair is opening up about yet another symptom she's started to experience as a result of her disease: hair loss.

"My right eyelashes all fell out except 3 corner ones," she recently shared in an Instagram post. "Happened in end of August."

Now, she wrote, her left eye is losing its lashes, too. "Just started falling out in left eye so there goes my profile posing," she shared. "I guess [my] immune system figured it has bigger kids to spank. I'm going to bed. With a lack of lashes but an abundance of love and beautiful flowers."

While hair loss isn't a symptom of MS itself, it can happen because of various medications used to treat the condition, according to research published in the journal Neurology and Therapy.

Others with MS who've also experienced hair loss took to the comments section on Blair's post to share their support for the actress. "Losing my lashes too," one person wrote. "It's from the meds. Not fair we have this crappy disease at least we should be able to keep our hair."

"Selma, my eyelashes, leg/armpit hair left me many years ago," wrote another. "I think of having none as a badge of honor."

Blair is one of some 2.3 million people in the world living with MS. In sharing the many ups and downs that come with having a chronic disease like this, Blair is not only raising awareness of MS, she's also helping others with the condition feel a little less alone. Thank you, Selma, for always being yourself, no matter what life throws at you.
