What is hair porosity?

Hair porosity is understood as the hair's ability to absorb and retain moisture, in addition to other substances from outside. The degree of porosity of the hair is determined by the outer layer of the hair fiber called cuticle. Depending on the opening, flexibility and state of the cuticle, there will be one type of porosity or another, since this is what allows water and other substances such as oils to penetrate and leave the hair.

Other types of factors such as genetics, chemical treatments such as dyes or bleaching, environmental influence, the hair products we use and the hair care routine we carry out daily also influence hair porosity.

Types of hair porosity

Each person has a type of hair porosity depending on the cuticle scales and exogenous factors such as hair care or aggression with dyes and heat sources. Depending on the opening of this cuticle, we can classify hair based on its porosity into three types: high, medium and low porosity hair.

High porosity

The main characteristic of hair with high porosity is lack of hydration. This is because at your open cuticle which makes them easily absorb moisture, but also lose it just as quickly. This makes the hair drier, tangled and frizzy or, in other words, with the well-known frizz.

Medium porosity

Hair with medium porosity has a more flexible cuticle, which makes moisture penetrate the hair more easily and remain in the hair fiber. This makes hair with medium porosity the easiest to care for and does not require considerable maintenance since the cuticle has a perfect opening to maintain proper hydration of the hair.

Low porosity

In low porosity hair, it is more difficult for water to penetrate the hair, in addition to making it difficult for the absorption of hair products since it has a more closed and intertwined cuticle. This is why this hair takes longer to get wet and is more likely to accumulate dirt. However, this type of hair retains moisture for longer when it has been hydrated.

How to reduce hair porosity

Knowing how to reduce hair porosity is key to keeping it hydrated and healthy. Although depending on the type of hair porosity we will have to choose one product or another, broadly speaking, it is essential to adopt a series of measures to avoid it.

Reduce the use of heat sources

It is advisable to reduce the use of heat sources such as irons, dryers and hair curlers to avoid possible damage to the cuticle that causes the hair fiber to dry out. If using them, it is advisable to apply a thermal protector before blow-drying to reduce the impact on the cuticle.

Limit dyes

Dyes, highlights, bleaching and permanent straightening have an aggressive composition for the hair. This is why it is recommended to limit its use or, if possible, opt for dyes that include ingredients of natural origin to minimize the impact on the hair fiber.

Follow a correct hair care routine

One of the keys to keeping porosity at bay is to follow a good hair care routine with products according to our hair type. Depending on the type of hair porosity we have, the use of certain products is recommended.

For hair with low porosity, it is essential to use light products that hydrate excessively. It is advisable to use shampoos formulated with ingredients such as almond oil, coconut oil or protein masks. In addition, it is very useful to rinse your hair with hot water so that the cuticle opens and the product penetrates the hair properly.

On the other hand, people with high porosity hair should use anti-frizz, moisturizing and strengthening products with formulations based on soy, arginine or keratin. In these cases, it is advisable to rinse the hair with cold water to close the cuticle.

In the case of hair with medium porosity, it is enough to follow a basic care routine without the need to apply highly moisturizing active ingredients such as those mentioned above. It is recommended to use a moisturizing treatment such as masks on a biweekly basis, and opt for shampoos without sulfates that can damage the hair fiber.
