I tried an Aubrey Organic shampoo a while ago and it made my hair incredibly dry!! I was thinking the same as waymire.. do your products contain protein? Have you done any deep conditioning treatments? My favorite products are in my signature. Have you tried a diluted ACV rinse after your shampoo? That might be beneficial.
