“From a pharmacist's standpoint, I couldn’t believe there was a product that could turn grey hair into black hair at first. But after studying the product and its ingredients carefully, I slowly began to accept that the product works, and bought it for my parents to use.” At first, the pharmacist’s parents expected to see significant results within one or two weeks, but after the pharmacist patiently gave them an explanation, they slowly realized that it takes about three to six months to restore the health of the scalp. Through Dr. Chen's constant reminder to use the product, they finally saw a difference after applying it diligently for a period of time. Now they use it every day and recommend it to their friends and relatives!
