Hmm. Okay. I think Leila is some very popular girl in the middle school, and she has a plan for all the cool girls to do something involving their hair (No, I don't know what). Katrina is only marginally popular, and she's having second thoughts about this whole hair-dying plan (whatever the plan may entail). She's asking Leila for reassurance that, no, she really should go through with it. That would explain why Katrina has to identify herself-- "heits me katrina"-- because Leila is SO COOL that she doesn't even bother to learn the phone numbers of those less cool than herself.

I have to say, though, I'm not entirely satisfied with this explanation. "my hair is almost brown"? Meaning it's like a dirty blonde? I don't get it.
