Msbuy is committed to ensuring that very satisfied customers are satisfied with your product and with our service, that our hair can be reused and that after 6 months – 1 year of careful care. Please note that each batch of original hair is unique and there is not an identical bunch. This is the nature of raw hair without treatment. Please check your purchased hair before installation. Before using our hair, please feel free to comb the brush (use a wide comb to comb your curls) or wet it if necessary, but do not cut off the weft or lace until you are satisfied. If there is any problem with the hair, please return it for replacement before use.
