Our wefts/weaves can be applied by glue, micro rings, weaved, sawn or alternately used for clipins. Can you cut the weft size according to your needs. The quality is Chinese Remy which means that they are high-quality cuticle correct (all hair strands running parallel in the same direction) effectively means that this prevents tangling and have not been mixed. If the hair is mixed the hair will tangle very easily. They can last up to 12 months providing correct aftercare is taken. You can wash, curl, and straighten these extensions as you would do with your own natural hair.
