Isn’t silicone what contractors use to make tile seams watertight? Yes. It is.
So think of that when you see a hair product with silicone in it. Basically, silicone in your hair products is used to lockout moisture from your hair, with the idea of giving it a temporary shine, slip for detangling, smoothness and conditioned “feel”, but it’s a fake shine — a plastic shine that over time has the opposite effect.
Silicone coats the hair so it keeps nutrients from getting in or penetrating the hair, which can cause hair to weaken or break. With continual use, it will eventually weigh the hair down making it dull and lifeless. In essence, you get a good look and feel for a couple of days, but over time it will attract build up in the hair and dry it out causing frizz and breakage because the “seal” that the silicone creates won’t allow conditioner or moisture into the hair which ends up sitting on the surface.
Silicone is found under many names in all types of hair products such as shampoo, conditioner, detanglers and shine serums so to identify them, a loose rule of thumb is to look for words that end in “cone” such as Dimethicone, Cyclomethicone, Pheryl Trimethicone.
If you want really healthy hair, not just the temporary appearance of healthy hair, going silicone free is definitely the ticket.
