It probably turns 1-2 times. The higher the coil count the more textured the hair appears. Every place a curl turns is slightly thinner that in the curl itself. These thinner parts of hair are more fragile and therefore more susceptible to breakage. So, the higher the coil count the more fragile the hair is.
Curly hair grows away from the scalp.
The curlier the hair the more it stands up from the scalp. The further away from the scalp, the less the natural scalp oil can be distributed onto the hair shaft. Without the natural hair oil produced by the scalp, hair loses moisture and becomes dry and finally brittle. So, the curliest hair is the most fragile and the least likely to get the protective layer of natural oil so it is also the driest hair. Don't shampoo more than once a week.
