High Porosity Hair

High porosity hair takes in moisturizers very quickly, but, unfortunately, it loses them rapidly. In some cases, this problem it’s hereditary, but mostly, it’s caused by all the chemicals we apply on our strands. That includes bleaching, color treatments, using all sorts of irons, hairdryers, and even the sun. They all have an adverse outcome on your threads.

To better understand what is happening to your hair, you must know that each thread has three layers: cuticle, cortex, and medulla. When having high porosity hair, those cuticles are too far apart, so the moisturizer gets in quickly, but it doesn’t have time to do its job because it comes out as fast as it got in. When this happens, the thread is not moisturized enough, and it will frizz, tangle, and look dry even if you applied nourishing products.

But don’t panic, there are ways you can deal with this problem and get gorgeous hair! Protein treatments are your best friends because they fill those dense pores. Use them once a month, and the results will be noticeable.

Also, opt for a shampoo and conditioner that contains no sulfates, silicones or parabens and insert oil and butter in your hair routine. There are also a few sealing oils that will do an astonishing job: castor oil, grapeseed oil, or jojoba oil. Butter is also a good option, they highly nourish and moisturize, but they are harder to spread on your strands.


Low Porosity Hair

At the other pole, you can find the low porosity hair. Remember those cuticles we talked about? In this case, there is no space between them, so the moisturizers or water can’t get inside. It’s like hair tries to repeal everything that wants to pass in. All the products you apply remain on the hair and don’t get soaked.

However, there are a few tricks you can do to change hair porosity! Consider using heat caps when moisturizing the hair; this way, all the nourishing products will get absorbed. Oils, butters, and silicones are not a good option for low porosity hair, use only light, refreshing sprays and shampoos without moisturizers. Clarifying shampoos are also ideal products for this hair type.
