It can also cause hair loss. Even if you wash shampoo out many times, 30 percent of the chemical substances still remain in the hair and the residues make it more sensitive, causing hair loss, experts said.

Further, it causes wrinkles on your face due to the scalp aging. A shampoo with surfactant destroys layers of a scalp, making it dry, and naturally escalating the aging of the facial skin.
