Humectant and brightening
The legend says that one day, protesting Canadian tar sands oil, Lush staff completely covered themselves with black molasses to mimic the dirty fossil fuel; and when the time for a good rinse arrived, their locks were so bouncy and so bright that they gave the inventors the idea of putting molasses in hair care products.
To understand how molasses are made, let's look at the process of making sugar. Sugar can be made from several different plants, but in the case of molasses, it is derived from the sugar cane. The top of the subtropical plant is harvested, washed and crushed, to separate the fibres from the juice. The juice is then boiled to make the water evaporate, obtaining a thick dark syrup, which will be boiled again until sugar crystals are formed. Molasses are the leftovers of this last process, they are the syrup that did not crystalise.
Molasses have a thick consistency and a sweet taste, very close to caramel. Applied on skin and hair, it gives similar effects to honey, helping to retain moisture and giving a gorgeous glow.
