Why does Fructis Triple Nutrition have 3 layers?

Fructis Triple Nutrition Nutrient Spray has 3 layers. Have you ever wondered how that works and what each layer does for your hair?

How do the layers work?

The trick is there are three immiscible fluids that have different specific gravities (SPG). That means that the liquids won’t mix together and will separate into different layers. And since each layer has a different weight it will either rise to the top or sink to the bottom. Based on the ingredient list (see below) it appears that the three main ingredients are water, cyclopentasiloxane (a silicone), and isohexadecane (a hydrocarbon oil.)

Water is the heaviest (SPG = 1.0) and will sink to the bottom. The dyes used in this formula are also water soluble which explains why only the bottom layer is colored. The silicone has an SPG of about 0.95 so it’s just a little bit lighter than the water and the isohexadecane is much lighter with an SPG = 0.78 so it floats on the top.

Are 3 layers better for your hair?

What does this all mean for your hair? Well not a whole lot. The water and the silicone, for the most part, will completely evaporate. The oil will stay behind and provide some lubrication. This is mainly a gimmick to give the product a unique appearance and support claims of “triple nutrition.”

    Hi I have a question. Since I have fine hair I lack volume so I was wondering maybe if you could guide me about volume boost shampoos, do they really work? Is it worth to spend large amount of bucks ? And last which conditioner should I use for my hair? Volumising or normal one?
