High Porosity Hair Guide and Best Products
High porosity hair has a raised or damaged cuticle layer, allowing moisture to easily enter and exit the hair shaft. This type of hair absorbs water and products quickly but also loses moisture quickly. It also has a missing or damaged lipid layer, which means it needs more conditioning to protect it and make it feel healthy. Not what you expected? Read our science-based explainer at our blog.

Characteristics
- Absorbs water and products easily
- In the past we thought it dried quicker, but scientific research shows it may actually dry slower because it absorbs too much water internally, which can cause swelling and tangles
- Prone to breakage
- May look dull without proper care
- Products made with plain oils/butters may not work as well as those with positively charged conditioning agents
Care Tips
- Use leave-in conditioners to protect the hair from further damage
- Be gentle with your hair when styling and protect it from friction with bonnets/silk pillowcases when you sleep
- Consider bonding products to help repair the hair and balance its water content
- Look for products with positively charged conditioning agents that bond to damaged hair like behentrimonium chloride
- Look for products specifically formulated for damaged hair
- If using heat, always use a heat protectant
