When going natural be prepared for major shrinkage and frizz at any given moment, particularly the day of or after a wash. Depending on the day, product or weather, my hair has been known to shrink up to three or four inches. Also beware of humid environments and over fluffing the hair, as these are surefire ways to retract a curl and bring on the fuzz.
Some good solutions to combating frizz and shrinkage; find a good moisturizer and keep it close, try a blow-out/twist-out, and only undo your twists when your hair is completely dry. You can also stretch the hair by wearing a bun or any other updo post-wash.
