Flowers of sulfur is good for growing hair quicker. But the main idea is to preserve your ends. I honestly don't believe in terminal length, but I've never experience issues with growing since I stopped cutting it/straightening it. If your hair stops around your shoulders, that's more than likely NOT terminal length--it's probably just breakage. Also curly hair may appear to grow slower since it curls, but if you track growth you might be pleasantly surprised.
Mostly 3c and lovin' my curls

This is not a fashion trend, it's not a statement, it's pride for who we are and what we look like. And that is where our true beauty shines.
