What exactly is dimethicone?

Dimethicone is a silicone-based ingredient widely used in skin foundation, skin moisturizer, 2 in 1 shampoo, hair conditioner, and other skin and hair care products.

Is it always bad? Depends on the perspective.

Why shampoo products should avoid using dimethicone?

The purpose of using shampoo is to remove dirt and scalp sebum.

However, as we mentioned, the molecular weight and silky-smooth texture of dimethicone in shampoo might make it hard to rinse off.  Then it leads to improper scalp cleaning and causes scalp problems such as excessive oil secretion, oily dandruff, scalp pimples, etc.

After using a shampoo with dimethicone, your scalp might have dimethicone residue which could clog pores and coat hair roots, then weigh your hair down.

Treat your scalp and hair differently!
  • Scalp care – Focus on cleanliness and avoiding dimethicone. Use shampoo to remove scalp buildups (scalp sebum), sweat, and dirt.
  • Hair care – Focus on moisture. Use a hair care product (conditioner) and avoid applying it on your scalp.
