The BEST hair growing shampoo conditioner and serum! This stuff has saved my hair during perimenopause! After turning 40 I noticed more shedding and because of hormone fluctuations I did notice a change in hair health and length. But this saved my hair! The GRO kit is the best value because it comes with all 3 products! LTKBeauty LTKFindsUnder100 LTKOver40
