30 inches light brown hair, 4 inches thick

Never dyed, bleached, or chemically treated. Heat use (curling or blow-drying) on average once every 4 months.

I have cut as much of my hair as possible (buzz cut on #0 setting). The hair is divided into 15 braids. The longest pieces were 32 inches when straight, so the longest cut pieces are at least 30 inches.
The bottom half of the hair has been thinned and there are some split ends; please see photos.

Nonsmoker. Hair shampooed and conditioned once every two days.
