Braids and dreadlocks are technically different. Dreadlocks are knotted and really hard (if not cant be taken out unless cut off) to take off. Braids is just the hair braided and not permanently braided. So Dreadlocks are more dirty because you are not supposed to wash them and their are rules for upkeep for it.
Basically its complicated.
But the hair seems fine to me but i cant really tell 100%.
