Hair Porosity: What you need to know

You likely have heard of people talking about hair porosity on social media and wondered if it is something you even need to know about. I mean, is it getting into the weeds about what the average person needs to know to keep their hair healthy or is it something you really should consider when planning your hair care routine? Easy answer...you should absolutely consider your hair's porosity when choosing products.

Hair porosity is your hair’s ability to absorb and hold moisture. It affects how well moisture and oils pass in and out of the external layer of your hair, called the cuticle. Your hair's porosity can affect how your hair holds on to color, absorbs hair treatments, conditioners, etc., as well as how it feels (dry and brittle with frizz vs. soft, shiny, elastic and smooth).

It is typically classified into three categories:

1. Low porosity: Cuticles that are very close together (aka, it is difficult for treatments, oils, water, and hair color to penetrate the hair shaft).

2. Medium (or "normal") porosity: Cuticles that are less tightly connected. This is healthy hair that can absorb moisture, color, etc and retain the benefits of them.

3. High porosity: Widely spaced cuticles. All of the above go in really fast and leave even faster (aka, hair color grabs really dark and fades really fast, hair feels dry, damaged, experiences breakage, as it cannot hold on to the moisture from treatments, oils, serum, etc that give the hair strength and health.)

When you think of your hair's condition in respect to porosity, you see why understanding it is so important to your hair's overall health. For instance, if you're looking at high vs. low porosity hair, what hair oil you choose has everything to do with that oil's ability to penetrate the hair shaft. The best oils for low porosity hair, like jojoba, marula, Kalahari melon seed and sweet almond oil, are lighter and have the ability to be more easily absorbed.

Whereas the best oils for high porosity hair are heavier oils, rich in Omega-6 acids, like like grape seed oil, sunflower seed oil, pumpkin seed oil, safflower oil, walnut oil, soy oil, corn oil, and wheat germ oil.

Why spend money on products that are all wrong for your hair? The goal of any beauty regimen is to improve the health and appearance of your skin, hair, etc., so it is always in your and your wallet's best interest to consider the most important factors. When it comes to your hair, these are:

Hair Texture - Curly, Wavy, Coily, Straight

Hair Type - Fine, Medium or Thick

Hair Porosity - Low, Medium or High

It is quick and easy to test your hair porosity at home. You need a glass of water (use a clear glass) and a strand of your hair. It is recommended that you try this after washing the product and build-up from your hair to get the most accurate reading.

1. Start by combing your hair to release strands that are shedding.

2. Take those strands and drop them into your glass of water

Low Porosity Hair: Will float.

Medium (aka Normal) Porosity Hair: Will float then begin to sink slowly.

High Porosity Hair: will sink immediately.

Once you determine your hair's porosity, you can choose your products and hair oil specifically geared toward optimum health and manageability.

• Hair takes longer to dry

• .Products tend to build up on the hair rather than absorb

• Natural oils don't readily penetrate, but rather sit on your hair

• Hair takes longer to get fully saturated when you wet it

Hair Care Tips for Low Porosity Hair

Low porosity hair has very compact cuticles, so it’s hard to inject moisture and color into the hair shaft, although it does retain moisture and color once it absorbs.  Use an ultra-rich treatment at least once a week and to raise the cuticle which will help it retain moisture and color, follow these steps:

1. Use heat. That's right, heat. Use a deep conditioning treatment, like our Innersense Hydrating Hair Masque or Naturally Drenched Rebalance Pre-Conditioner Treatment under a hooded drier, steamer or even a warm towel or shower cap, to help products better absorb and bind with the hair. Grab one of our Aquis towels, heat it up and wrap your hair for 25 minutes!


2. Always apply products to damp, not drenched hair.


3. The best shampoo for low porosity hair is sulfate-free and includes moisture-rich, easily absorbable oils.


4. Use a clarifying shampoo, like O&M’s Original Detox Shampoo, before applying any hair mask for hair treatment to ensure the hair shaft is free of any build up and can benefit from all the goodness of that treatment. They're also recommended before a color service to ensure your hair is ready to absorb maximum color.

5. The best oils for low porosity hair will seal in the moisture by absorbing into the hair shaft. The hair structure is left protected, without weighing it down. These include grapeseed, argan, marula, jojoba, apricot, pomegranate, Kalahari melon seed and sweet almond oil. The fatty acids in these oils make it a great choice for low porosity hair.

• Hair has bounce and elasticity
• Requires very little maintenance
• Easily accepts and retains color and moisture inside of the cuticle
• Holds styles well

Hair Care Tips for Medium Porosity Hair

Medium porosity does not necessarily mean perfectly healthy and easy maintenance. It has a looser cuticle layer, allowing for a steady but moderate flow of moisture in and out of your hair; however, it still needs hydration, moisture and nourishment to be healthy, shiny and youthful.

Choose oils that regulate sebum secretion, condition, moisturize, soften and improve hair elasticity like Macadamia, Sunflower, Wheat, Linseed and Pumpkin Seed Oils.


Continue to do regular deep conditioning and Olaplex No. 3 Treatments to maintain good product absorption.

• Hair easily absorbs water, however, it requires more products
• Hair looks and feels dry
• Hair often looks frizzy
• Hair dries quickly
• Hair loses its color or toner quickly

Hair Care Tips for High Porosity Hair

Parched, thirsty hair needs products to help it retain as much moisture and color as possible, so follow these tips to increase hydration and strength.


1. Use minimal heat. It’s best to air dry your hair, if possible.  We know this is difficult, so at a minimum turn down the temperature on your styling products. We love our Babyliss curling irons! Heat makes the cuticle open and color escape so monitor how much you use.


2. Incorporate regular deep conditioning or Olaplex 0 and Olaplex 3 treatments into your hair care routine. Twice a week, Use Olaplex 3 or Evolvh Ultra Repair Reconstructing Masque to begin to repair the bonds and porosity of your hair


3. Rinse with cold water to seal the cuticle and prevent color from sliding out.  Hot, hot showers aren’t good for your skin or hair. They are drying and open the cuticle to let the color escape.  Can’t take a cold shower? No problem. Wash your hair with cold or tepid water, then bag it in a shower cap and crank up the heat.


4. Detangle gently with a wide-tooth comb or our Tangle Teezer Detangling Brush for Fine or Fragile Hair to prevent hair loss and reduce hair breakage.  Use a detangling spray like O&M Know Knott Detangler when combing through.


5. Avoid tight ponytails and top buns.  The hair can get stress fractures from over pulling and tugging causing your hair to break and come highly porous in those areas. Try doing a low bun or even wearing a French braid.  Change it up. When you do a pony or bun, use a anti-breakage hair tie like one of our Goomee Hair ties.


6. The best oils for high porosity hair include omega-6 acids, like grape seed oil, sunflower seed oil, pumpkin seed oil, safflower oil, walnut oil, soy oil, corn oil, wheat germ oil, etc. You should also try oils rich in omega-3 acids, e.g. linseed oil, strawberry seed oil, raspberry seed oil, blackberry seed oil, etc.


7. Finally, combine a moisture locking leave in conditioner like Oway’s No Rinse Moist Conditioner to help seal moisture and combat thirsty porosity
