Shrinkage = the amount by which something becomes smaller or less.
The photo on the left is my hair wet, while the photo on the right is my hair dry. There are many products that "claim" to control/prevent shrinkage, but I'm not really a believer. Sometimes I am able to have less shrinkage by pulling my hair up/back at night, and releasing it in the morning. But depending on the mood my hair is in, that may cause other problems (i.e. frizz, messed up curls, lopsided hair, etc.).
Shrinkage is a reality for all us coily girls. No matter what....I know that my hair is going to have some sort of shrinkage, unless I'm wearing it straight. It's just another fun fact about being a naturalista!
