What Causes High Porosity Hair?
There are two main causes. Some people are born with it. Others get it from damage.
Genetics
Some people just have a naturally more open cuticle. If your parents have dry, frizzy hair, you might have to deal with the same problem. A natural hair is often more porous due to its shape: Curly and coily hair types tend to be more porous because the cuticle rises at each curve of the hair’s strand.
Heat Damage
Flat irons, curling wands and blow dryers all provide extreme heat. Heat raises the cuticle and heat can even damage the cuticle. It has Protracted gaps if used too often, that’s the truth.
Chemical Treatments
Bleach, hair color, relaxers, and perms all affect the hair’s structure. The biggest cause is bleach. It opens the cuticle to strip color, and it can’t always close.
Rough Handling
Brushing wet, knotted hair also damages the layer. The same goes for tight hairstyles and unfriendly towel drying. Over time, that adds up.
Sun and Weather
Strong sunshine, wind the hair’s outer coating. Salt water can also dehydrate hair.
How to Do a Hair Porosity Test
Porosity test: You can test hair porosity at home. Here are three simple methods. For best results, begin with your hair free of any products.
The Float Test
- Pick a few strands of hair clean and hold a few clumps of hair clean.
- Put them in a glass of room temperature water.

The Spray Bottle Test
Pick a small section of clean, dry hair. Spray it with water. If the water absorbs at once, your porosity is high. When water lies on your hair in beads, your porosity is low.
The Strand Slide Test
Hold one strand between your fingers. Run your fingers upwards towards your scalp. If the strand is rough or feels like you have nothing but tiny stick quarters on your finger, your cuticle is raised. That points to high porosity.No test is perfect. Give two or three a go, and trust what you see.
