How long is too long? I have been trying to grow my hair long for years but never this long. Â This woman’s hair is neatly 9 ft long, 8 feet 9 inches to be exact. She has been growing her hair for 20 years. She has submitted herself to the Guinness Book of World Records for longest dreadlocks. It takes one bottle of Shampoo and Conditioner every time she washes her hair, which is once a week. I think that is going to be expensive for her in these economic times. Sometimes it takes days for her hair to dry. Â She has very long hair but if you check out the article you will see that she only has one dread that is really long and the rest of her hair is just long. I don’t think I could deal with all this hair, it looks really heavy. Check out the article at AOL.
