After more than 15 washes, various treatments and a trip to the emergency room, her hair still hadn’t moved.

“My hair has been like this for about a month now — it’s not by choice,” she said in the video…

In a second video, Ms. Brown demonstrated an attempt to wash it out: She filled her palm with a generous amount of shampoo, slathered it over her head and rubbed furiously. She wiped off the suds, which did not appear to have penetrated the glue layer, and seemed to be close to tears.

She later posted on Instagram that a combination of tea tree oil and coconut oil that she left on her head overnight was an “epic fail.”
