What are silicones and Why are they in your hair products?
WHAT ‘SILICONE-FREE’ REALLY MEANS
A lot of products claim to be “silicone-free”. And yet despite all the controversy and skepticism in this ingredient, it seems like silicones still get used in a lot of products. This becomes confusing to many people who have heard the controversy, especially the curly girls. Now everyone is unsure what is bad about silicone, or if it is actually bad. In today's blog, everything will be explained.
WHAT ARE SILICONES?
IS SILICONE GOOD FOR HAIR?
Silicones became an industry staple because the effects that they give are difficult to accomplish with alternative ingredients like oils.
Silicones has been known to be a water repellant that is drying to the hair, which makes anyone with curls run as hydration is essential for them. But not all silicones are the same.
- Occlusive Silicones: These are the water-repellant silicones. They form a barrier or layer on the hair and stay there, unless removed with a cleanser. Some examples are certain forms of dimethicone or amodimethicone. If left on the hair, they form a barrier that keeps moisture out of the hair and can cause hair to dehydrate over time. If any ingredient in your shampoos, especially harsh waxes and silicones are hard to rinse off, build up will increase over time and cause scalp issues, and overall brittleness in the hair.
- Water Soluble Silicones: Unlike occlusive silicones, these ingredients wash away with water. They’re easily emulsified, and oncethey are in contact with water, they are removed from the hair. Some examples include: Cyclomethicone, PEG-12 Dimethicone and Dimethicone Copolyol, (both water-soluble forms of dimethicone) or Polysilicone-29. These are generally good ingredients to have in your shampoo or hair products.
- Volatile Silicones: Volatile silicones are completely different than most. These ingredients are typically added to products for initial slip and shine, but they don’t stay in the hair. They actually evaporate as hair dries. Examples include Cyclopentasiloxane, or Trisiloxane. There’s no reason to fear these ingredients, because they disappear on their own.
Curly girls are still able to achieve the slip, shine, and silkiness with alternative ingredients. These ingredients are often oils, waxes, or mineral oil. Some of these can be good or bad. Some of these ingredients can even be worse than silicone alone. It is important to look at all ingredients before purchasing a shampoo. Let's discuss some of these ingredients.
- Jojoba oil
- Vitamin E
The smaller the molecule of the oil – the easier it is to emulsify and avoid build up (like argon oil). Luckily, most ingredients are not made of pure oil, and only have a small amount to give enough benefits to curls. Using pure oil like coconut oil will cause buildup and breakage overtime.
Mineral Oil and Waxes
If you use these, make sure you wash them away with a shampoo that doesn’t include any ingredients that stick to hair and scalp and don’t easily rinse off, otherwise you will just make matters worse!)
- Dimethicone (High Molecular Weight)
- Dimethicone/Vinyldimethicone Crosspolymer
- Cetyl Dimethicone
Waxes can form barriers and create buildup. If you use these, make sure you wash them away either with a clarifying shampoo from time to time or a very gentle daily shampoo. If you wash your hair often, I would avoid wax based products all together.
- Castor wax
- Carnauba Wax
- Candelilla Wax
- Lanolin wax
These are difficult to wash off and are heavy. If you use these, make sure you wash them away with a good clarifying shampoo.
- Mineral Oil
- Hydrogenated Vegetable Oil
- Linum Usitatissimum (Linseed) Seed Oil
- Hydrogenated Polyisobutene
- Brassica Campestris (Rapeseed) Seed Oil
Rinses off, easily emulsified. Best kind of oils for hair care. .
- PEG-7 Glyceryl Cocoate
- Olive Oil PEG-7 Esters
- PEG-6 Caprylic/Capric Glycerides
- PEG-40 Hydrogenated Castor Oil
Water Soluble Silicones
Rinses off, easily emulsified. Best kind of silicones for shampoos and products.
- PEG-12 Dimethicone
- Silicone Quaternium-18
- PEG/PPG-20/15 Dimethicone
Silicone that evaporates. One of the best ingredients to have in your shampoo.
- Phenyl Trimethicone
