If you can relate, you are in the right place as we’ll be sharing with you what you need to know about straightening low porosity hair and more.

Introduction To Low Porosity Hair

Low porosity hair features tightly aligned cuticles that act as a ‘stop’ sign for moisture trying to enter and exit the hair shaft. It typically occurs in straight hair types and is generally associated with fewer ‘pores’ in the hair cuticles, the outer protective layer of your strands.

This hair type tends to be shiny and smooth, but it could feel very dry and straw-like if you’re dealing with product buildup and because this hair type doesn’t retain moisture for long.

If your hair does not sink in a beaker of water, consider you have low-porous hair.

Low Porosity Pros

  • Retains moisture better: This hair type has the best moisture retention level of any porosity level because the cuticle layer is locked down tightly. Without product buildup, this hair type won’t easily lose moisture or appear dry.
  • Shiny and smooth appearance: A flat, tightly closed cuticle layer leaves strands smooth and better able to reflect light. In contrast, medium and high porosity hair has rougher strands thanks to the lifted cuticle layer and won’t look as shiny or smooth.
  • Doesn’t tangle: A smoother cuticle means fewer knots, snags, and tangles, thanks to the sleek texture of strands. High porosity hair, in contrast, has a very rough cuticle layer and is easily tangled.

Low Porosity Cons

  • Trouble absorbing moisture: The tightly-arranged, flat cuticle layer is what makes this hair type so great at retaining moisture, but the flip side is that it’s hard for this type to absorb moisture in the first place. Heavy moisturizing products and conditioners may just sit on the hair instead of penetrating and absorbing.
  • Prone to breakage: When it isn’t absorbing enough moisture, brushing, styling, and even sleeping on the wrong pillowcase can all trigger unwanted hair breakage.
  • Longer time to dry: This hair type makes it hard for water to enter or leave strands, so it takes a long time to leave once water works its way in. Air drying can take a lot longer with some reporting it takes up to 24 hours to completely air dry their hair.
  • Specific products: If you have hair with low porosity, you need to consciously avoid products containing any form of protein.

Selecting products that help hair with low porosity hair is absolutely essential for a healthy, manageable mane.

Your low porosity hair routine should in fact include washing once a week to keep it soft, moisturized, and free from buildup until your next wash.
