This is my second time reinstalling my Belle Noir Signature Curl. Length 18inch. Probably about 8 ounces or less because of the length.Im a self installer. I never cut the wefts, just fold over and keep going.I installed 2/26/09 and as of 3/23/09 its still in, but i will be taking it down this weekend. i miss my hair...but it will be back in for memorial day!!! I love this hair!! I only use herbal essences "totally twisted" curls and waves shampoo and conditioner and it works great! and smells soooo good! Since being on BHM i learned about plopping so i do that everytime i co wash..it helps with drying and my hair always looks sooo curly and full after wards..enjoy looking!
