Dimethicone: You’ve probably spotted some version of it on skin and hair care labels. And when you’re pressed for time, chemical names like “polydimethylsiloxane” are tough to decipher – so into the basket it goes.

As a brand that’s committed to eco-friendly practices, we wanted to set the record straight about dimethicone in skin care and hair care (and why you’ll never find it in our products).

What Is Dimethicone?

From diaper rash creams to moisturizers, hand lotions to liquid foundations, hundreds of personal care products use dimethicone for easier application.

Makeup primers are a "prime" example because silicone-based polymer molecules are too large to be absorbed by skin. That means they leave behind a silky/slippery layer that keeps your makeup looking flawless. 

Dimethicone in hair care products helps to coat the hair cuticle, improve detangling, and provide shinier, smoother tresses.

Is Dimethicone Safe for Skin and Hair?

According to the FDA and Cosmetic Ingredient Review (CIR), dimethicone is a safe skincare ingredient that calms irritation, minimizes redness, and protects the skin from further damage.

Board-certified dermatologist, Dr. Julie Jackson states that dimethicone “does not interact with the stratum corneum (the top layer of the skin). It works by forming a film that prevents the loss of water through the skin that helps keep the skin moisturized. It also works as an emollient, which means that it fills the spaces between cracks in the skin.”

Though it’s an unnatural, man-made substance, dimethicone is a good chemically-inert moisturizer and safe for skin. When asked whether dimethicone is known to clog pores, Dr. Jackson concludes, “There is no evidence that dimethicone causes acne.”

Dimethicone for Hair Is a Different Story

In hair products, dimethicone is known to leave shinier tresses that are easy to detangle. However, that waxy buildup can start to prevent water from making contact with the hair cuticle – and that can lead to dryer and/or damaged locks.

Curly and fine hair may also get weighed down by buildup. If you have these hair types, you already know that extra heft is the opposite of what you want.

Is Dimethicone Bad for the Environment? 

The short answer: Yes.

Depending on the route your water takes, when dimethicone (a hydrolyzed chemical) is washed down the drain, it can feed into aquatic environments and impact fish and plant life.

The National Center for Biotechnology Information also states that “the use of low molecular weight silicones should be reduced...and the purity of high molecular weight silicones should be monitored.”

Introducing the Best Dimethicone-Free Shampoo & Conditioner

Very few eco-friendly hair products provide the same results as silicone-based ones. We know because we spent years perfecting our Natural Shampoo & Conditioner

From our biodegradable plant extracts to organic essential oils, Puracy has always believed that the right balance of biodegradable ingredients could perform just as well as their synthetic counterparts.

The biggest change in our haircare reformulations came from Lexfeel N5. This 100% sustainable and biodegradable texture enhancer seamlessly replicates the effects of dimethicone and silicone.

We’re extremely proud to be one of the first companies to use this plant-sourced ingredient in our hair care line. And we're even prouder that our hair products leave all hair types moisturized, bouncy, and shiny.
