Washing the dreadlocks is a good idea to keep them clean from residue buildup. Synthetic dreads have the advantage that you can wear up and down and even wash them without damaging them. The dreads are relatively easy to wash as compared to natural dreadlocks. You can shower your scalp using the usual shampoo and use the shampoo on synthetic dreads that are meant for dreads. Dreadlocks accumulate the buildup, so using a residue-free shampoo is favorable. Skip the conditioner and don’t wash the dreads frequently. Avoid hot water and try to use lukewarm otherwise, it can damage their texture.Moreover, try not to wash the dreads frequently as it shorter their life span and results in messy synthetic threads. Less washing increases the life span of dreadlocks and will help you maintain a neat look, and it also prevents their early fuzziness. If you are not comfortable washing the dreads with natural hair, wash the dreadlocks in the washing machine and hang them to dry.
