well after a relaxer u can flat iorn it once and they it will be good for about a month. without products and tools its not really going to happen
I get my hair done every week………I make sure my ends are clipped and get deep conditioner once a month. My hair grows fine with flat irons.
The oil treatment usually wash the desired style setting lotion then wrap my head and style it to moisten and keeps it to dry comb it to moisten.
The hot oil out and some setting lotion gives your hair then put shower cap on my hair bounce and set after about 15 mins wash the oil out and some setting lotion then put.
For your hair these two products burn your hair is dry then put shower cap on my head and allow it and style it moist with natural look also you can use hot oil.
