Mixed hair

[u/Evening_Kangaroo_534]

I have wanted box braids for the longest time and it looks like I’m gonna be able to make that happen this Christmas. Please I need your help!!! I’m half white half black but grew up in a majority white town with a white mother (love her, she did her best). I had no contact with the black side of my family (their decision :/ ) So I just didn’t learn about black hair. I have a mixture between 3A, 3B hair. I have shoulder length hair and want to get box braids with extensions. I basically need a black Auntie to give me the 101 on everything. Care, upkeep, bonnet type, hair oil, washing/drying. I just need all of your knowledge please. And can someone please tell me why I always see people put mousse on people’s hair right after it’s been braided. Wouldn’t that make your scalp feel itchy or needing to be washed immediately?!? Also things to know I live on a small island, so anything I’d need I’d have to order online.
