According to the report of Popular Health Network, Liu Lihua Black Hair Shampoo can't really change the color of hair. Shampoo may make hair brighter, softer and healthier, but this is a temporary effect and won't really make hair black. This is because white hair is usually caused by insufficient melanin particles in the body. Shampoo can only act on the outer layer of hair and cannot directly affect the production of melanin in the body.
