Normally, my go-to protective style is flat twists without extensions. When I install protective styles that required extensions, I go for box braids or jumbo twists. These braids or twists last about 3 to 5 weeks. If you live in Nigeria, you already know the heat and humidity can do many things to your hair and edges. I will not recommend carrying braids for longer than 5 weeks. I suggest you let your hair extensions hang loose whenever you are indoors. That way, your scalp gets some air so no lingering funky smell stays trapped in. While some people use rose water on their hair to promote hair growth, I like to use it to make my hair smell good.
