Silicon, also known as dimethicone, cyclomethicone, and various other names, is used in hair care products primarily for its ability to create a smooth and shiny appearance, reduce frizz, and make hair easier to manage. While silicone can provide short-term benefits, there are several reasons why it may be considered harmful to hair in the long run.
Long-term effects of silicons:
- Buildup: Silicon forms a non-water-soluble layer on the hair shaft. Over time, this layer can accumulate and create a buildup on the hair. This buildup can make the hair look dull, heavy, and lifeless, as it interferes with the hair’s natural ability to breathe and absorb moisture.
- Reduced Moisture Absorption: The silicon coating on the hair shaft can act as a barrier, preventing moisture from entering the hair. This can lead to dryness and dehydration of the hair over time, making it more susceptible to damage.
- Prevents Nutrient Penetration: Silicons can also hinder the penetration of essential nutrients, such as proteins and amino acids, into the hair shaft. This can impede the repair and strengthening of the hair, ultimately leading to weaker, more brittle strands.
- Diminished Styling Potential: While silicons can initially make hair easier to manage, the buildup it creates can also make it more challenging to style. It can weigh down the hair and reduce its natural volume and bounce.
- Decreased Natural Shine: Over time, the silicon layer can create a false shine, masking the hair’s natural luster. When this coating is eventually removed, either by harsh shampoos or after a period of discontinuing silicon-based products, the hair may appear lackluster and damaged.
- Scalp Issues: The buildup of silicon on the scalp can lead to issues like clogged hair follicles, itching, and flaking. These issues can potentially contribute to hair loss or reduced hair growth.
- Environmental Impact: Did you know that silicon is not biodegradable and can have an environmental impact? When it washes down the drain, it can accumulate in waterways and ecosystems.
What’s the alternative?
Not all silicons are created equal, and some are lighter and less likely to cause the issues described above. Look for products that contain water-soluble or volatile silicons, which are less likely to build up on the hair.
Ultimately, the impact of silicons on hair can vary from person to person, depending on individual hair type and the specific products used. Some individuals may not experience significant issues with silicon, while others might find it detrimental to the health and appearance of their hair over time.
Water-soluble silicons, also known as water-soluble silicons or volatile silicons, are a category of silicon compounds that are less likely to build up on hair and can be removed more easily with water-based shampoos. They are often preferred in hair care products to avoid some of the issues associated with non-water-soluble silicons.
Here are some examples of water-soluble silicones:
- Dimethicone Copolyol: This silicon is water-soluble and is often used in hair products to provide conditioning benefits without the risk of heavy buildup.
- Lauryl Methicone Copolyol: Another water-soluble silicon derivative, this compound is used in hair products for its conditioning properties.
- PEG-8 Dimethicone: It is a water-soluble silicon that can help with detangling and reducing frizz without causing buildup.
- Dimethicone PEG-8 Phosphate: This silicon is both water-soluble and has emulsifying properties, making it suitable for a wide range of hair care products.
- Cyclomethicone: While not entirely water-soluble, it is a volatile silicon that evaporates after application, minimizing the risk of long-term buildup. It’s often used in hair serums and leave-in products.
- Amodimethicone (with PEG-12 Dimethicone): This is a modified silicon that combines the benefits of amodimethicone with a water-soluble component (PEG-12 Dimethicone) to improve its wash-out properties.
These water-soluble silicons offer the advantages of traditional silicons, such as improved hair manageability and reduced frizz, without the drawbacks of excessive buildup. They can be beneficial for individuals who prefer silicon-based products but want to avoid the potential long-term effects on their hair.
