I don't believe that's Alicia's natural curl pattern. I hear people saying she's a 3b all the time and I don't believe it. She has dye damage and heat damage in her hair.
Naturally she's a 3c/4a mix leaning more 3c IMO:
By high school she definitely looks like she's texturized. And yep..she definitely got that nose done too.
Personally..I like her damaged hair though just fine. Looks pretty to me when she just lets it go wild like in the photos BlessedBMyRoots posted.
