here is how i wash my daughters hair in braids. sorry so long !
i take out her braids from the week and i put it into 4 big braids. i dont braid them too tight or too loose. about a medium to loose tightness. then i rinse her braids and scalp really good. i get my fingers all up in there to the scalp. this is why you dont wanna braid tight. then i put the shampoo in my hands and starting at the top section of on braid i work my fingers trhough the hair to the scalp getting her nice and sudsy then i work that soap down the braid. now here you are gonna have to sorta squeeze the braids this will work the soap in to them. all the way to the tips. do this on all of them. then rinse like crazy over and over. til the water runs clear and you would want to be squeezing those braids while your rinsing as well. to get the water into the middles. at this point i squeeze as much water outta the braids as i can. wrap her braided head in a towel. i mix her conditioner with EVOO and castor oil. when her hair is no longer dripping i take out 1 braid at a time and get this mix thoroughly through each section and braid back up. i do not detangle at this time. when she is saturated, i cover her head with a plastic bag and then cover that with her nighttime scarf. send her on about her playing business til im ready for her. sometimes 30 mins.....sometimes 3 hours......lol. when its time to rinse, i rinse her out still braided. squeezing and rinsing like i explained before. when the waters clear then i wrap her head in towel again and get her to "the hair chair" lol, and take out the braids one at a time and this is when i detangle. my kid is sooooo tenderheaded but since i have been doing it this way there has not been a single tear. no lie! everyone that gets bad tangles should give this a try.
