What Is Low Porosity Hair?

Your hair’s porosity refers to its ability to retain moisture. Low porosity hair means – you guessed it – your hair struggles to absorb and hold onto moisture most.

This is because the cuticles of your hair are tightly packed, so any moisture has a harder time penetrating your hair shaft.

Low porosity hair also tends to be dense in texture, as the kinks and coils are tightly packed.

This also makes it more vulnerable to breakage and dryness.

Should You Deep Condition Low Porosity Hair?

Long story short – yes, you should absolutely use deep conditioner on low porosity hair.

Locking in moisture is essential in order to ensure your strands are as healthy as possible.

You need ingredients that won’t just coat your strands but will absorb into them, restoring hydration to parched locks and minimizing any breakage.

The best ingredients to look out for in deep conditioner for low porosity hair are:

  • Shea butter
  • Oils such as coconut, sweet almond, jojoba, and argan

That said, the best deep conditioners for low porosity hair should be lightweight.

Whether or not you opt for one with protein in is entirely contingent on your hair type.

Some products add protein to them. This can manifest in ingredients like:

  • Keratin, collagen, or biotin
  • Hydrolyzed wheat, quinoa, rice, or soy protein
  • Hydrolyzed silk

The idea of using a protein-rich product is that the protein works to restore and repair any damaged or broken hair strands.

If you regularly color your hair or expose it to heat from styling or processing, protein can therefore be a godsend.

It will work to rejuvenate your hair’s natural bonds and reduce further breakage or shedding.

However, too much protein in hair can make it dry and brittle, and it will feel hard or rough to touch.

If your low porosity hair is protein sensitive, using a product with protein in it will only cause further dryness and frizz.

Knowing your hair’s protein level is therefore vital to ensure you choose the best deep conditioner for low porosity hair.

How To Test Your Hair Porosity

One of the easiest ways to test your hair porosity is the strand test.

  1. Shampoo your hair (this removes any build up).
  2. Gently take a strand of hair from your head.
  3. Add this to a glass of water.

If your strand sinks quickly, you have high porosity hair. Alternatively, if it floats, your hair is low porosity.

How Often Should You Deep Condition Low Porosity Hair?

You should aim to condition your hair every time you wash it and incorporate a deep conditioner into your hair care routine roughly once a week.

If your hair is still super dry, you can up this to twice a week.

Low Porosity Hair Mistakes To Avoid

Protein

Remember, if your hair is protein-sensitive, you need to be avoiding deep conditioners with added protein. They’ll make low porosity hair even dryer and more brittle.

Using A Deep Conditioner With Chemicals

Chemicals like sulfates, parabens, phthalates, and other nasties have innumerate negative effects.

They may damage your hair or scalp – particularly if you have sensitive skin – and lead to dryness, frizz, and breakage.

Equally, they’ll likely build up more – which is a no for low porosity hair.

Using Heavy Oils

With low porosity hair, you want to be using thinner, lighter oils as these will penetrate into your hair strands and intensely moisture.

Heavier oils will form a slick on the surface of your hair but not work to hydrate strands from the inside out.

The best oils include coconut oil, avocado oil, and argan oil. Oils like jojoba, grapeseed, and castor oil are sealing oils, so they will lock moisture in.

Choosing a deep conditioner for low porosity hair with a combination of these oils is, therefore, best, as they’ll complement each other, working to hydrate strands and sealing in moisture.
