Pinup/Updo's
Updo's are great protective styles for all types of hair. It's important to protect your ends from drying and splitting, and protective styles are the best source. Updo's are also great for length retention. Learning how to properly manipulate your hair is also a good source for length retention.
In all, updo's saves you time in your morning routine, or whenever you're prepairing to go out.
Free-Styles
I love free-styles although I don't recommend Naturals of certain textures/lengths to wear them too often, consistently. Nevertheless, free-styles are beautiful on all textures, and with proper maintenance, they can last for a substantial amount of time. Remember to keep your free-styles moisturized and protected at bedtime to prevent dryness and breakage.
