Bests & Worsts Reviews from Amazon

I used Hairfinity 2-3 yrs ago on my daughter and myself and it stopped ALL breakage and the hair grew a few inches and I didn't need to trim it. My daughter and I are doing the same no different and our hair is coming out like crazy when we're combing and when we wash it comes out in clumps!! What's going on? Before we lose all our hair! Not exactly sure the company I got this from maybe its second hand but I want my money back!!
