Dreadlocks and Alopecia
Inevitably, long hair of any kind stresses the scalp. This can be worse with dreadlocks because hair that would usually be shed instead remains twisted into the dreads, meaning that, over time, there is additional weight on the roots. This can cause traction alopecia.
The best way to protect yourself against these problems is to wear your hair in a style that supports it against the top of your head, reducing the strain on the roots. This can mean tying it up (being careful not to do so too tightly) or wearing it inside a soft, breathable hat that provides support. You can still wear your dreads loose for special occasions, but if you look after them in this way you're a lot less likely to lose your hair.
The leading causes of alopecia in dreadlocked hair is twisting interlocking and over tightening of the roots which cause a constant tension resulting in permanent hair loss.
