What is can men use womens shampoo?

As an AI language model, I don’t have personal experiences and preferences. However, there's no harm for men to use women's shampoo as both are designed to clean and nourish hair. The main difference is that women's shampoos often have a different fragrance and are formulated with different ingredients that are specifically meant for the hair concerns that women have. So, if a man doesn't mind the fragrance and the specific ingredients used, they can definitely use women's shampoo. It ultimately depends on personal preference and hair needs.
