The chances of hair breakage around your crown are higher than in any other region of your scalp. This can be linked to trauma and damage to the hair follicles among others. However, there is one cause for breakage in this area that’s rarely discussed: high porosity.
The outermost layer of the hair, or the cuticle layer, is responsible for protecting the inner layer in the hair shaft. The cuticle layer consists of various scales that are flat or either lifted, affecting the movement of moisture between the cortex and the environment. This is where porosity comes into play. Women who suffer from high porosity have missing or damaged scales. This renders their hair unable to transfer the moisture to other hair strands.
Are Porosity and Crown Breakages Related?
Yes, these two aspects are directly linked to one another since the crown is exposed to severe damage at a structural level. As is the case with hair strands, the texture of your scalp and porosities vary as well. Even though the rest of your hair is low on porosity, there’s a chance that the crown may have high porosity.
Constant exposure of the crown to the sun’s ultraviolet rays is a major contributing factor to this issue. If you don’t wear a hat or scarf whenever you go out, your hair may end up growing slower, weaker and sometimes with an entirely different structure. Dry hair can also elevate this issue, so keep moisturizing your tresses to protect them from the elements.
Now that you have a good idea about the link between these two aspects, you should put in extra effort to ensure that your crown is protected from everything that can harm it and cause hair breakage at that sensitive spot.
