I have been using watermans shampoo and conditioner for one month following noticing my hair had become thin and brittle -most probably due to taking steroids for a medical condition. I suddenly became aware of this and was fearful as I have always loved my hair. Although it is probably early to tell if new growth has come I certainly notice a silky moisture on the hairs surface, it seems thicker in volume and I am not losing hair. I wouldn’t use anything else now I have found this. I also use the application at night. Thank you!
