When choosing shampoo, you might have heard sayings like "go non-silicone because it clogs your scalp" or "silicone makes it hard for hair color to take." However, some people may wonder if these beliefs are actually true.
In this article, we interviewed Noboru Chiba, who has long been involved in the development of hair care products at Kao Corporation, which produces both silicone and non-silicone products such as merit. We asked him about the impact of silicone on hair and scalp, and how to choose the right hair care for your needs.

"Clogging the Scalp" is a Misconception—The Facts About Silicone

It's been over ten years since debate began around silicone shampoos, yet much confusion remains. According to Chiba, there are still widespread misunderstandings about silicone.
"The 'silicon' that many people hear about and the 'silicone' we use in hair care products are actually different things. 'Silicon' refers to the element found in semiconductors and in nature, while the substance in hair care products is 'silicone,' an organosilicon compound. This means it's silicon bonded with other ingredients.
