Cone – Cones are known as either pine cones (the woody fruit of a pine tree) or the orange cones we all see when construction workers are out and need you to slow down and steer clear of them working.
Cones for naturals is just short for silicone. Silicones are very effective ingredients in hair and beauty products. They work by covering hair with a thin hydrophobic (waterproof) coating and that coating will keep humidity out softens the hair.
Some naturals stay clear of them because they can cause build-up (most are non-water soluble) but it all depends on the individual preference if they like them or not in their hair care products.
