Help, I'm obsessed

Help, I'm obsessed with her🦋. I found two of her dolls at Ross last week, and I found another two today at a different Ross. I don't even know why I'm so drawn to her. Now I have four (for now—I'll get every single one I see) and I’m planning to let her hair down. But since she has twisted braids and her hair seems thin, I’m wondering if anyone has tried taking her hair down yet. Also, I’m not a Bratz doll expert—can her hair handle a boil wash?
