Hair porosity is the ability of the hair to absorb moisture. There are three categories of hair porosity: low, medium, and high.
How to Know Hair Porosity?
The Different Types of Hair Porosity
The following are quoted from essence.com
A. Low porosity
The cuticles are a little tight and resistant to receiving water and moisture, and it cannot absorb water, and products easily.
- To get moisture to penetrate the hair, you should use products containing more alkaline ingredients that will help lift your cuticles.
- High acidity works to keep the cuticle closed.
- For extra moisture, steamers can help lift the cuticle to get moisture to your hair.
- Avoid overusing oils and butters.
- Avoid using products with a low pH.
- When setting styles, always try to start on damp hair.
B. Normal Porosity
Holds moisture and shine for an extended period of time. However, normal porosity can change. If you use heat often, relax your hair or chemically process it in some way, your hair porosity can change over time. Be sure to stick to a healthy hair care regimen to maintain the normal porosity of your hair.
C. High Porosity
If your strand sank, it’s likely riddled with gaps, tears and openings that allowed water to easily flow in. If you think your hair absorbs products quickly but loses the moisture just as fast, you may have high porous hair.
- Try using butter and oils to help lock in moisture your strands naturally easily lose.
- Rinse your hair regularly using an apple cider vinegar mix, and applying aloe vera gel and protein treatments to temporarily fill gaps can help manage high porous hair.
Note: There is no way to completely repair high porous hair, but you can try by using these quick and easy tips.
