Hair porosity. Maybe you have read about it when you dove into the many sources of no ‘poo information… Maybe you haven’t. In any case, being aware of your hair porosity is key. (determine yours here)

What is hair porosity?

Above you can see a picture that displays the three types of hair porosity. As you can see, it is about the the outer layer of your hair: the cuticle. The cuticle has small layers that either lay flat or stick out. Your porosity is influenced by hair damaging.

As you can maybe imagine, cuticles that stick out are easier to access since they ‘stand open’. This means that, when using a moisturizing product, it penetrates easily. Downside is, that it easily leaves the hair as well.

Opposite is when the cuticles lay flat. It is harder for moisturizing products to penetrate, but it also does not leave the hair easily. 

These are the two ‘extremities’: low and high porosity. Let’s dive deeper in to the three types. 


First off, the low porosity type. Low porosity has the flat laying cuticles. 

The hair is considered to be ‘closed off’: it does not let in easily and it does not let go easily. This counts for moisturizer, water, oils etc. 

Tips for low porosity hair:
– Use heat when using a mask. Heat opens up the cuticles and therefore helps penetrate into the hair.
– Use humectants. Humectants attracts and retains moisture – such as honey or glycerine.
– Do not overuse protein. Since your hair does not have that many gaps, it is not necessary to strengthen them with protein. Which is why you will ‘overdose’ quickly.
– Do not use heavy oils. Since the hair leaves oils rather than absorbing it, it leads to buildup on the strands. 


The medium porosity is considered to be ‘in balance’. It accepts enough moisture and prevents the escaping well. It does not need as much care as with the other two.

Tips for medium porosity hair:
– Listen to your hair: care for it when it lets you know. This way you will not overdo or damage the hair into high porosity or neglect it into low porosity.
– Translated into care: deep condition when necessary, use protein when necessary. 
– Maintain the balance this way 🙂


Finally, the high porosity type. High porosity is defined as the out sticking cuticles. 

The cuticles sticking out lead to gaps, which lead to quick loss of moisture as it escapes easily. It also lets in very easily. High porosity is defined as damaged.

Tips for high porosity hair:
– Use a conditioner everyday. For instance a leave-in in a spray bottle, so that you can apply easily every day.
– Use minimal to no heat. As the hair is damaged and vulnerable, heat can damage the hair more.
– Seal the cuticles from damage and too much moisture. Use gels or rinse with cold water after washing/rinsing. 
– Another note on the vulnerability: be very gentle when detangling.

The more you can adjust your care to your hair’s needs, the better. Hopefully you understand your hair better with this knowledge!
