Curly hair takes about twice as long to grow length than straight hair. Depending on the curls. Mine are almost the size, maybe a little bigger than my index finger. A year and a half and it is well past my shoulders and wet reaches my nipples.
But curls are a girl's best friend other than diamonds. Curly hair is probably the most feminine other than bangs. But remember the old saying, "girls with straight hair want curly hair and girls with curly hair want straight hair." Well I love my curls. I don't even want straight hair. Wash it, condition it, put frizz serum or argon oil in it and a little gel. Shake like a dog and fix it with my fingers and let it dry naturally. Really easy, instead of straightening irons and blow driers. Healthy, curly and soft and pretty freaking girly.
