Herbal Medicine- Hair-Skin-Body -Nails 101

I am so excited to start the 7 days with my daughters hair. But I have a couple questions, which maybe aren’t appropriate for this group (maybe I need to join 101) so please just let me know! She has had box braids for 6 weeks and we are going to rebraid it in a week because we are going on a beach vacation. So, when I take the braids out tomorrow, what should I use in her hair to detangle and remove buildup before shampoo / conditioner? I searched through so many of Cyn’s videos and didn’t see that step anywhere. She has high porosity hair and extremely tight coils (Prior to finding Cyn would have said 4c). Also, need to trim it so I a. Going to attempt the blow dry and straighten and I’ve heard you mention multiple times that temp matters for avoiding damage, so wondering what that should be. Thank you in adVance, Im grateful I’ll be able to teach my daughter truth with her haircare, instead of what everyone has guilted me into doing!!
