High porosity hair can be pretty hard to grow since it breaks easily and is very hard to keep moisturized. To understand the porosity of hair, we first need to take. a look at the structure of hair.
Each strand of your hair is made up of three layers:
➡️ cuticle: the outermost layer
➡️ cortex: the middle layer
➡️ medulla: the innermost layer
The cuticles protect the inner layers of your hair by controlling how much moisture 💦, as well as products and chemicals, can be absorbed.
Low porosity hair, the cuticles are close together making it difficult for moisture to be soaked up.
High porosity hair, the cuticles are far apart, so moisture can easily get into the hair, but it doesn’t stay long enough to nourish and moisturize your hair.
The difference in the porosity of hair is whether the protective layer or hydrophobic lipid is flattened or not. In low porosity hair, the cuticle is smooth or flattened and the appearance of the hair is shiny 🌟 and absorbs less water 💦. In high porosity hair, the cuticles are raised, this means the cuticles have wide openings which allow water in easily. High porosity hair can be genetic but it is mostly caused by over processing the hair or styling treatments like straightening, blow-drying, bleaching, and other chemical applications.
Top tips for managing high porosity hair:
