HAIR POROSITY
Let's start by defining porosity. It refers to how well your hair is able to absorb and retain moisture. Low porosity hair has a tightly closed cuticle layer that makes it difficult for moisture to penetrate the hair shaft. This can make the hair feel dry and brittle. High porosity hair, on the other hand, has a raised cuticle layer that allows moisture to easily enter the hair shaft. However, it can also cause the hair to lose moisture quickly, leading to frizz and dryness.
SPECIFIC NEEDS OF LOW POROSITY AND HIGH POROSITY HAIR.
Low porosity hair needs products that are lightweight and easy to absorb, such as leave-in conditioners and serums. It's also important to avoid products that are too heavy or greasy, as they can weigh the hair down. For high porosity hair, it's important to use moisturizing products that will help to seal in moisture and prevent frizz. These include oils, butters, and deep conditioners.
To figure out if you have low or high porosity hair, there are a few simple tests you can do at home. One way is to take a strand of hair and place it in a glass of water. If the hair floats on the surface, it's likely low porosity. If it sinks to the bottom, it's likely high porosity. Another test is to feel the hair after it's been wet for a while. Low porosity hair will feel dry, while high porosity hair will feel damp. Have you tried either of these tests?
