I stopped coloring my gray hair mid November 2019. The gray hair currently sprouting are brittle, weak, and dry. I saw the Ginger Nutrition Shampoo manufactured by Guangzhou Sasa Comestics Manufacturing Co., Ltd offered by an Amazon Seller at a discounted price I decided to give it a try. I have not seen any satisfying result from using the shampoo. I have received a coupon from the seller I'm definitely planning on purchasing an extra bottle hopefully I will see a difference.
