Why the Porosity of Your Hair Matters

1. Low Porosity:
   Low porosity hair has tightly closed cuticle scales, making it resistant to moisture absorption. This hair type often appears shiny and smooth, but can be prone to product buildup.
2. Normal Porosity:
   Normal porosity hair has a balanced cuticle structure, allowing it to absorb and retain moisture effectively. It is generally easy to manage and style.
3. High Porosity:
   High porosity hair has open cuticle scales, which causes it to absorb moisture quickly and lose it just as fast. High porosity hair tends to be dry, frizzy, and prone to damage.

1. Product Selection
   Understanding your hair's porosity can help you select the most suitable hair care products. Low-porosity hair benefits from lightweight, water-based products that won't weigh it down, while high-porosity hair may require richer, more emollient products to lock in moisture. Normal porosity hair can generally work well with a variety of products.
2. Moisture Management
   Hair porosity directly impacts how your hair retains moisture. High porosity hair requires extra care to prevent moisture loss, such as regular deep conditioning and sealing the cuticles with natural oils. Low-porosity hair may require products that encourage moisture penetration, such as heat-activated treatments.
3. Styling Techniques
   Knowing your hair's porosity can also influence your styling techniques. For example, high-porosity hair may benefit from protective styles that reduce exposure to environmental factors. In contrast, low-porosity hair may require heat styling to slightly open the cuticles for improved product absorption.
4. Damage Prevention
   High-porosity hair is more susceptible to damage due to its open cuticles, making it essential to handle it gently and avoid overprocessing with heat or chemicals. On the other hand, low-porosity hair may require extra care to remove product buildup, which can lead to scalp issues and hair damage.

1. Take a clean strand of hair (it's best to do this after shampooing) and place it in a glass of water.
   
2. Observe how the hair behaves:
   
   If it floats on the water's surface, your hair is likely low porosity.
   If it sinks slowly, your hair is probably of normal porosity.
   If it sinks quickly, your hair will likely have high porosity.
