Washing hair without shampoo, also known as "no-poo" or "co-washing," is a growing trend involving the use of alternative cleansing methods aside from traditional shampoo products.
This approach has gained popularity due to its perceived benefits, including reduced scalp irritation, improved hair health, and environmental friendliness. Historically, no-poo practices have been traced back to ancient times, with civilizations using natural ingredients like clay, vinegar, and herbs to cleanse their hair.
