Characteristics of hair with high porosity:

If you recognize several of these points, you probably have a high porosity

  • Your hair will get wet quickly and will dry (super) quickly again
  • Products are absorbed very quickly
  • Many split points
  • Your hair feels dry
  • Lots of fluff
  • Lots of tangles
  • Fine and or curly hair will suffer faster
  • You blonde your hair and/or you paint a lot

A clear sign, however, is how much water your hair absorbs when it gets wet. On average, it takes up up to 30% of its own weight in water, while severely damaged hair can absorb up to 50% – so half – of its weight. The drying times also give good indications: it naturally differs a lot in length, but if your hair is dry within half an hour without help, then it is probably very porous.

Characteristics of hair with low porosity:

If you recognize your hair more here, then you probably have a low porosity

  • It takes a long time before your hair is thoroughly soaked and it dries very slowly
  • Products tend to stay on top of your hair
  • Coarse hair has more scales, so it is less likely to be porous
  • Healthy and strong hair
  • Shiny hair

Pay attention! Build up of. For example, silicone can seriously disturb the image. For example, your hair may have dried out, but at the same time, no moisture can enter or exit because there is a thick layer on your hair. That is why it is good to clarify – you have special shampoos for this – to remove any build-up for a better image of your hair.

What does porosity mean for my hair care?

Provide high porosity:

Hair that is very porous needs a lot of care to become and stay healthy and needs to be well protected. In addition, it is very important to be as careful as possible with your hair to prevent damage to the hair cuticles.

  • Use strong care products. Exchange your conditioner for a good hair mask tailored to your hair type. If your hair responds well to silicone, try a product with somewhat heavier silicones (dimethicones). A hair mask with oil is definitely recommended.
  • Enclose desired moisture and unwanted moisture. You can do this by applying aloe vera gel or oil to wet hair, for example. The ROO method is also highly recommended.
  • Apply oil before jumping into the shower or swimming. This ensures that your hair absorbs less water and therefore has to endure less. It also forms a protective layer over your hair, making it less likely to be damaged by combing, for example. Read, for example, what coconut oil can mean for your hair.
  • Detangles in a gentle way. Try to prevent as much damage as possible, use your hands, and if you have straight hair, always detangle when your hair is dry.
  • Do not use heat. Your hair has already dried out. If you blow-dry, use the cool setting.
  • Stop painting/bleaching or keep it to a minimum
  • Use a mild shampoo or no shampoo at all
  • Wear your hair in protective hairstyles, such as the nautilus bun
  • Maintains acidity, this is very well possible with an ACV (apple vinegar rinse)

Provide low porosity:

Low porosity is something positive, but it can sometimes be a challenge if you just want to get more moisture in your hair, for example, to better hydrate your hair. Again pay attention to build up, which can give the false idea of ​​low porosity.

  • Use lighter products. Products with a lot of oil and silicone remain on your hair
  • Use lighter oils – A little is enough. Oils such as jojoba are very suitable for this
  • A little warmth can help to incorporate treatments such as SMTs better
  • Do not use products on wet hair on dry hair to keep your hair well hydrated


My own hair is quite porous, despite the fact that I have not been painting for years. But I am blessed with fine hair that breaks very easily. Strangely enough, the hair at my roots dries faster than my dots. I think this is because I did not wash my dots with shampoo and also treat it with a lot of product and oil. Good care really makes the difference, and you can reduce a high porosity to a normal low and very acceptable porosity.
