Low Porosity Hair
When thinking about hair porosity, I think of hair as a sponge. Porous hair (high pH level) is like a sponge with large holes, taking in a lot of moisture. Low porosity hair is like a sponge in a plastic bag. It's hard for liquid to penetrate it, but if held under water, eventually the sponge absorbs the liquid. Porosity is mainly controlled by how 'tightly' closed the cuticles on your hair are. The cuticles close in acidic conditions, and open more in basic conditions.
Symptoms of Low Porosity Hair:
* Hair floats when you do the strand test (put a clean strand of hair in a cup of water and see if it floats or sinks)
* Hair takes a while to get wet
* Hair takes long to dry
* Water and oil just sit on the hair
* Hard to moisturize (aka your hair stays dry)
* Hair is sensitive to protein
* Relaxers don't "take"
If any of this applies to you, you may have hair with low porosity! My hair definitely has trouble retaining moisture, takes a while to dry sometimes, and floats when I put it in water. I realized a couple of months ago that my hair had low porosity because treating my hair with low pH levels wasn't working.
Ways to manage lo-po hair:
Use warm water to rinse. It is recommended that we rinse conditioner out with cold water to seal the cuticle, but since low-porosity hair already has a closed cuticle, you don't want to seal it anymore.
Stay away from acidic shampoos and conditioners. For a while I was using Roux Porosity Control, but eventually I noticed that it either did nothing for my hair, or it made it hard. My hair can take apple cider vinegar (ACV) sometimes, but not a lot and not often. I've been using Organic Root Stimulator Aloe-Rid Shampoo, which I love. It clarifies my hair, opens my cuticles enough to accept a deep condition, and makes my hair soft.
Steaming. The hot steam will open up the cuticles, which is why so many low-porosity heads love steaming. I don't have a steamer, so I do the "DIY" method, which is applying conditioner, then a plastic cap, then a very hot wet towel, then another plastic cap, then another hot towel, then another plastic cap. Then I sit under the dryer for at least 15 minutes.
Use moisture-rich products. It is said that this hair type is least resistant to damage through styling and grooming, but it's really important to keep it moisturized. Be careful with the protein! My hair doesn't seem to be too sensitive to protein, so I try to incorporate a light protein in my hair for every wash, whether it's the pre-poo, deep condition, or leave-in conditioner. It's even more important for low-porosity hair to have a good moisture/protein balance. I'm still on a the hunt to find a good moisturizer. My hair is also sensitive to too much oil, so I have to be very light-handed when applying oils.
DC with heat. This is important. It's even more important to deep condition for a substantial amount of time. If I can, I'll leave in my conditioner over night, or for hours while I do housework/run errands/go to the gym.
Baggy the hair. This is basically bullying your hair to accept moisture. Because my hair is fine, baggying for a long time turns my hair into mush and makes it even more fragile. So, I usually baggy for about 2 hours at a time and that's it. I apply a little moisturizer and then put on a plastic cap for a couple of hours. I've only been doing this for a couple of weeks, about 3 days a week, but I can already tell a difference in my moisture level.
Heat before relaxing to open the cuticle. I don't have a problem with relaxers straightening my hair, but many women will flat iron or blow dry their hair before relaxing to open up the cuticles so that the relaxer takes a shorter time to straighten the roots.
Use alkaline products with a high pH (above 6, or so). Baking soda rinse - baking soda is alkaline.
Apply a semi-permanent color. Semi-permanent color lifts the cuticle
I am not sure if my hair always had a low pH level, or if it came with having a child or just getting older.
I'm determined to keep my hair moist, thick and healthy, so I will continue to try new products, techniques and tools!
That Thread really helped me address my overly porous hair.
