Silicone-Free Shampoo and Conditioner: Is Silicone Really That Bad for Hair?

Have you ever experienced greasy-looking, stringy hair after shampooing? We usually think that shampoo should leave us with squeaky-clean, shiny, and voluminous locks.

But if your shampoo contains bad silicone for hair, your shampoo may be doing more harm than good, especially if you’re also using a shampoo containing sulfates. Keep reading to learn more about silicone and shampoo, and how to find the best sulfate and silicone-free shampoo and conditioner.


What is Silicone in Shampoo?

Silicone is a chemical compound found in many cosmetic products, including shampoo. Silicones are polymers derived from silica, a natural mineral. Silicones can have many different names, but they usually end in “-cone” (i.e. “dimethicone”).

Silicone in shampoo coats each hair strand, locking out frizz-causing humidity. Think of it as a raincoat for your hair! Silicone in shampoo can also help to improve hair’s shine and manageability. If you’ve ever used a new shampoo and condition and noticed an instant improvement in your hair’s appearance, that’s thanks to silicones!

But here’s the thing: since silicones only coat the hair, they don't do anything to improve its condition. And in fact, they can harm your hair’s health.

Why You Should Choose a Sulfate and Silicone-Free Shampoo

Silicones do have a lot of benefits for the hair, at least aesthetically. However, silicone in shampoo can also have a dark side.

As we mentioned before, silicone does not penetrate the hair. Instead, it creates a film on top which can prevent other helpful ingredients from reaching the hair shaft. If you use a shampoo with "bad silicones" for hair (more on bad silicones for hair below), you may experience one of two issues:

  • Dry hair. Since silicone in shampoo prevents hydrating ingredients from penetrating your hair, your hair may become dry and brittle over time.
  • Greasy hair. As your hair becomes drier, your scalp may produce more oil to compensate. The result? Oily-looking hair. This can trigger a dangerous cycle. If your hair looks oily, you should wash it, right? But washing more often with shampoo containing bad silicones for hair will only exacerbate the issue.

Silicone Build Up

So what does buildup from silicone look like? It depends on your hair type. If you have straight or fine hair, the build-up will make your hair look limp and lifeless. Silicone build-up may mean less bouncy curls or a loss of curl altogether if you have curly hair.

Signs that your hair is experiencing negative effects from silicone in shampoo: the hair routine that once left you with shiny, healthy-looking locks is no longer working. If your shampoo and conditioner suddenly stop working like they used to, you may have a buildup of silicone on your hair.

Unlike other ingredients considered “bad” for hair, silicones aren’t harmful to your health. However, buildup from silicones on the scalp can cause an itchy rash. Silicones are also comedogenic, which means they clog the pores. If you are prone to acne, silicone in shampoo could make your scalp breakouts worse.

Hint: if you are experiencing a dry, itchy scalp due to silicone in shampoo, try Grow Perfect™ Thickening Spray. This spearmint-infused formula provides soothing relief for irritated scalps. Plus, it gives hair instant volume and may even promote healthy hair growth!

There’s another reason why you should choose a silicone-free shampoo: silicones are bad for the environment. Since the bad silicones for hair don’t break down easily in water, that means that they are non-biodegradable. When you wash your hair, silicones rinse down the drain. Eventually, these silicones accumulate in the water supply and cause pollution.


So what about sulfates? Bad silicones for hair and sulfates are designed to work together since sulfates' abrasive properties wash away silicone buildup. For example, a shampoo and conditioner duo may contain silicones in the conditioner to improve the shine and manageability of hair. To wash away the buildup for silicones, the shampoo may contain harsh sulfates. Over time, washing and conditioning hair with sulfates and silicones can lead to dry, brittle hair that’s prone to breakage. For healthier hair, opt for sulfate and silicone-free shampoo and conditioner.

What Are Bad Silicones for Hair?

Not all types of silicone are bad silicones. Silicones are stable, which means they do not degrade when exposed to heat or UV light. This means that they are helpful in products that are used to protect hair against heat styling tools or direct sunlight.

However, if you are using silicone hair products regularly, you’ll also want to use a clarifying shampoo without silicone to remove build-up. Alternatively, you can use silicone-free styling products like Thermal Shield™ Heat Protectant or Ocean Water Sea Salt Spray to prevent build-up from occurring in the first place.

Where you don’t want silicone is in your moisturizing products. As we mentioned before, silicone cannot penetrate the hair. Thus, it does nothing to hydrate parched strands. That’s why it’s important to choose a silicone-free shampoo and conditioner, especially if you have dry, damaged, or thinning hair.

Not all types of silicone in shampoo are created equal. There are two main types of silicone in shampoo: water-soluble and fat-soluble.

Water-Soluble Silicones

Using regular shampoo and water, water-soluble silicone in shampoo and other products can easily be rinsed out of the hair. Sometimes these silicones are referred to as “breathable”. They provide the shine and conditioning effect of silicones without the buildup as they easily and simply can be rinsed out with water. Some types of water-soluble silicone in shampoo include:

  • Dimethicone Copolyol
  • Lauryl Methicone Copolyol
  • PEG-8 Dimethicone
  • PEG-12 Dimethicone
  • Dimethicone PEG-8 Succinate
  • Amodimethicone (when the ingredients Trideceth-12 og Cetrimonium Chloride are present within the same formula)

Fat-Soluble Silicones

Fat-soluble silicone in shampoo is difficult to remove from the hair and scalp and may require a sulfate shampoo or a clarifying scalp scrub like Scalp Delight™ Detox Scrub (silicone and sulfate-free). Some ingredient names to look out for include:

  • Dimethicone
  • Cyclomethicone
  • Amodimethicone (when the ingredients Tricedeth-12 and Centrimonium Chloride are not present within the same formula)
  • Phenyl Trimethicone
  • Cetearyl Methicone
  • Dimethiconol
  • Stearyl Dimethicone

For healthier hair, make sure to thoroughly inspect the ingredients list of your shampoo bottle for fat-soluble AKA “bad” silicones.

What to Do if There’s Silicone in Shampoo

So what should you do if your current shampoo contains bad silicones with hair? The first thing to do is to use a clarifying shampoo like Scalp Delight™ Detox Scrub. This sulfate and silicone-free shampoo gently removes shine-dulling and itchy residue from the scalp. Hydrating botanicals like organic aloe leaf juice and acai fruit extract soothe and moisturize the scalp and hair while Gluadin® Kera-P LM (a hydrolyzed vegetable protein) restores protein-deficient strands and supports hair growth.

Use this shampoo for a dry and itchy scalp with the Scalp Delight™ Scalp Massage Brush to improve your results. The Scalp Delight™ Scalp Massage Brush has soft bristles that improve circulation and gently exfoliate the scalp. Plus, it just feels really good!

How to Find the Best Shampoo Without Silicone

So how do you find the best shampoo without silicone? Many shampoos that are labeled “silicone-free” actually just don’t include bad silicones for hair. That’s why it’s important to reference the list above when shopping for a silicone-free shampoo and conditioner. If you want to avoid silicone in shampoo altogether, look for products with natural emollients and conditioning agents like botanical oils.

I recommend opting for a deeply hydrating products enriched with plenty of nourishing plant extracts and moisture sealing proteins, like Moisture Hero™ Shampoo and Moisture Hero™ Conditioner. If you ask me, it is one the best shampoos for dry hair!

Promote healthy curly hair with Curl Crush™ Shampoo, a silicone-free shampoo. An active blend of vegan micro-proteins, bamboo extract, and a moisturizing sugar complex reconstruct and hydrate frizzy hair for smooth, defined curls.

What About Silicone-Free Conditioners?

You should opt for a silicone-free conditioner for the same reason you should opt for a silicone-free shampoo. Bad silicone for hair builds up on the hair shaft, leading to brittle and oily-looking hair. It doesn’t matter whether that bad silicone is in your shampoo, conditioner, or styling products. It will have the same effect! Instead, choose a silicone-free conditioner that uses natural botanical ingredients like aloe vera, shea butter, or olive oil to provide hydration and shine for hair.

Tip: For extra hydration and nourishment try a silicone-free hair oil or a leave-in conditioner, like Split Fix™ Leave-in Conditioner. It wraps hair in a conditioning veil to rebuild the structure of damaged, fragile hair and help smooth split ends, leaving your hair smooth, soft, and healthier-looking.
