Is Professor Xiong's Black Hair a national patent?

Professor Xiong's black hair is not a national patent. In the market, although some products have obtained the national patent certificate of "traditional Chinese medicine preparation for treating white hair and its preparation method", there is no cosmetic registration/filing named "Professor Xiong's hair root care cover". Professor Xiong's brand belongs to Biotechnology (Guangdong) Co., Ltd. [2], and its products include Professor Xiong Shouwu's Kushen Herbal Essence, Professor Xiong Shouwu's Kushen Hair Care Essence Milk, and Professor Xiong Jiayun's Hair Care Liquid.
