In the realm of hair care, understanding your hair’s porosity is key to achieving healthy and vibrant locks. Hair porosity refers to your hair’s ability to absorb and retain moisture. It significantly impacts how your hair responds to various products and treatments. Let’s explore what hair porosity is, how to determine your hair type, and most importantly, how to care for it, especially in Singapore’s humid climate.
Understanding Hair Porosity
Hair porosity is determined by the condition of the hair cuticle, the outermost layer of your hair strand. Think of it as a series of overlapping scales.
- Low Porosity Hair: The scales lie flat, making it difficult for moisture to penetrate or escape. This hair type tends to be resistant to product absorption and can take longer to dry.
- High Porosity Hair: The scales are raised, allowing moisture to enter and exit easily. This type of hair absorbs products quickly but also loses moisture rapidly, leading to dryness and frizz.
- Medium Porosity Hair: The scales are slightly raised, striking a balance between low and high porosity hair. This type generally has good moisture retention and responds well to most products.
Many Asian hair types, especially those with thicker strands, tend to have lower porosity. Understanding this characteristic can guide you towards the right hair care practices and products for your needs.
How to Check Hair Porosity
There’s a simple test to help you check for hair porosity that you can do at home:
- Take a clean strand of hair and drop it into a glass of water.
- Observe what happens:
- Low Porosity: The hair floats on the surface, indicating that it’s not absorbing water easily.
- High Porosity: The hair sinks quickly, indicating that it readily absorbs water.
- Medium Porosity: The hair floats for a while before slowly sinking, demonstrating a balanced absorption rate.
Caring for Your Hair Type

Now that you know what hair porosity you have, you surely have questions about how often should low or high porosity hair be washed or what kind of products work for low or high porosity hair. Here are some quick tips to help you out:
Low Porosity Hair Care:
- Washing Frequency: Due to the difficulty in absorbing moisture, it’s recommended to wash low porosity hair less frequently, about once every other day or once every two days, to avoid product build-up.
- Products: Look for lightweight, water-based products that won’t weigh down your hair. Avoid heavy oils and butters, which can sit on the surface and create a greasy feeling.
- Heat Styling: Applying gentle heat before applying products can help open the cuticles and enhance absorption.
High Porosity Hair Care:
- Washing Frequency: High porosity hair is typically drier, frizzier, and more prone to breakage, so you may want to wash it more frequently, such as once a day or once every other day. This will help ensure it gets enough nutrients on a regular basis.
- Products: Opt for deeply hydrating and moisturising products like leave-in conditioners and hair masks. Look for ingredients like shea butter, coconut oil, and aloe vera.
- Heat Styling: Minimise heat styling as much as possible, as it can further damage the already vulnerable cuticles.
These tips may also vary depending on your lifestyle. For instance, if you have a very active lifestyle, you should be washing your hair at least once daily to avoid the buildup of sweat or dead skin that could lead to scalp irritation.
Understanding your hair porosity is the first step towards achieving your hair goals. By tailoring your hair care routine to your specific porosity level, you can enhance moisture retention, minimise damage, and enjoy healthier, more manageable hair. Remember, consistency is key, so stick to your chosen routine and observe how your hair responds.
