This disclosure concerns improved polymeric thread for use in hair braiding. The novel threads used for this purpose are polymers that are stretched more than 10% during application as hair weave threads. Removal of the stretched threads is easily accomplished by applying a few drops of removal solvent or solution such as acetone to the extended thread, which breaks into short pieces that can easily be removed from hair with a brush, comb or by shampooing. This is highly advantageous compared to prior art hair weave threads, which must typically be cut to remove them from the hair, which both slows the removal process and introduces collateral hair damage, as some hairs are also accidentally cut when the prior art non-elastomeric hair weave threads are cut to remove them from the hair. The breaking of the extended threads is also much faster than the time required to dissolve the threads, and represents a new mechanism entirely for removing weave threads from hair.
