According to Dr. Green, “Natural shampoos are great for individuals with sensitive skin, allergies, and dry and colored hair. Natural shampoos do not contain harsh chemicals such as sulfates, alcohol, and parabens, which “can strip the hair of natural oils and coloring, leading to irritation, dryness, or dandruff on the scalp,” the NYC-based dermatologist added.

Additionally, by reducing perfumes, sulfates, and other harsh ingredients from a shampoo will help keep the hair soft from drying out, Penny James told Men’s Health. “Natural shampoo often has hydrating effects on the scalp. It can help balance the microbiome of the scalp,” the trichologist said.

Natural shampoos are also better for the environment. “Since they do not typically contain

polluting chemicals, the residual soap that travels down the drain will not harm oceans or waterways,” Dr. Green said.
