No Poo

no poo

No poo (short for ‘no shampoo’) is a collective term for methods of washing hair without commercial shampoo. Methods for washing hair without shampoo include washing with dissolved baking soda, followed by an acidic rinse such as diluted apple cider vinegar. Also honey and various oils (such as coconut oil) can be used. The notion of non-shampooed hair being unhealthy is reinforced by the greasy feeling of the scalp after a day or two of not shampooing. However, using shampoo every day removes sebum, the oil produced by the scalp. This causes the sebaceous glands to produce oil at a higher rate to compensate for what is lost during shampooing.

A gradual reduction in shampoo use will cause the sebaceous glands to produce at a slower rate, resulting in less oil on the scalp. Shampoo typically contains chemical additives such as sulfates (e.g. sodium lauryl sulfate). These chemicals can irritate the skin of sensitive persons (or of anyone if not promptly rinsed). Some shampoos also include silicone derivatives (e.g. dimethicone), which coats the hair, protecting it and making it more manageable; however, it also prevents moisture from entering the hair, eventually drying it out. Dimethicone is a common ingredient in smoothing serums and detangling conditioners.
