It seems as if the new craze are rod sets, and yes I have jumped on board. I will discuss why I prefer rod sets over twist-outs, but first let me discuss how I maintain my rod set.
I'm not new to rod sets, I used to do them all the time when I wore my hair straight, but since being curly, I haven't really thought about it. But my hair has been short, so, I guess that is the reason. It has been growing out really good, and since I was protective styling during the winter I didn't realize how long it has gotten, even though I trimmed my hair back in January. I have a problem with ends and always feeling the need to cut them, I like straight ends, but that is a story for a different day...lol
So, let's discuss how I style it and then maintain.
I wash, deep condition and apply my leave in, which is always Chocolate Souffle (it is my absolute fave!) I do have another brand that I will try out soon, but I am addicted to the Chocolate Souffle. But I do try to give my hair variety. Once I apply my leave in, I twist my hair in 6 twist, 3 on each side. I allow it to air dry a bit, about 2 hours. Once it has dried a bit, but still damp, I untwist each section one by one, apply my stylers (Buttermint Smoothie and Genesis) and then put the flexi rod on. I allow the flexi rods to stay on until my hair completely dries. I then take them out and immediately flat twist my hair, I flat twist it in the way I want my hair to fall. I flat twist immediately because the curls are too tight for my taste, and it stretches it out. This style stays in for a week. It can stay for 2 weeks but I wash every week.
I maintain this style by flat twisting every night. I apply Genesis first to each section. Genesis is a good sealer but I like to add it to my dry hair first because it has great slip, which helps to detangle the hair gently. I then apply a small amount of buttermint smoothie, and I mean a dab to my ends first and then hair and twist, bantu knot the ends and secure with bobby pin. I do this every night and wake up to fluffy soft hair. When I untwist, I apply a small amount of Spring Sensation oil to my hands and massage my scalp and then take each twist out. The last picture is actually 3 day old hair. Some will just put a bonnet on the hair without twisting ( I used to do this), but I twist because curly hair will do what it does best, tangle. When you twist, you avoid that and gain more moisture. If hair feels fully moisturized at the end of the day there is no need to apply any moisturizer, just twist and cover with scarf.
Hope this helps, if any is considering a rod set.
