Sounds like you have fine hair and possibly because of possible relaxing, you notice your hair seems to stay the same length rather that appearing to grow longer. I would recommend that you relax your hair only every 8 weeks. I would also recommend shampooing your hair every week with Dark and Lovely 3 in 1 shampoo, followed by Dark and Lovely Anti Breakage Healing treatment. This will fortify and strengthen the hair as well as hydrate it. This regiment used in conjunction with Dark and Lovely Anti Breakage Oil Moisturiser will strengthen the hair and reduce breakage by 10 times!
