Shampoos contain a variety of ingredients with different functions. Common ingredients include detergents, conditioners, thickeners, sequestering agents, pH adjusters, preservatives, and specialty additives. Detergents, or surfactants, are primary cleansers, while conditioners improve hair manageability and add luster. Thickeners, sequestering agents, and pH adjusters are also used to enhance the product. Additionally, shampoos may contain specialty additives such as chemical sunscreens, pro-vitamins, botanicals like tea tree oil, and natural ingredients like aloe, coconut oil, and essential oils. These ingredients serve to differentiate one shampoo from another and cater to specific hair needs

. When choosing a shampoo, it's important to consider the specific needs of your hair and scalp. For instance, if you have dry hair, you may want to look for shampoos containing moisturizing ingredients like coconut oil or aloe. On the other hand, if you have oily hair, you may want to avoid heavy conditioners and opt for shampoos with clarifying ingredients. Understanding the function of different ingredients can help you make an informed decision about which shampoo is best for you
