Helu. Comb. Helu (comb) or helu tu'aniu (coconut midrib comb) as they are commonly referred to, are ornamental combs which are worn by females in Tonga. They are a popular personal adornment amongst Tongan women and girls alike, and rose to popularity in the 18th century. Helu are primarily made from tu'aniu (coconut midrib), bound with pulu'i niu (coconut husk) and decorated with beads. Helu can also be made from other materials such as wood and tortoise shell and are ornately carved. This helu is rectangular in shape with a long extended tip. The tu'aniu is lashed with brown pulu'i niu, there is a thick section of lashing before the tu'aniu individually flares out at the bottom. At the top of the helu there are zig zag designs which have been lashed with black dyed pulu'i niu. The middle two tu'aniu extend from the top edge for app 15cms, this would be clearly visible when worn.
