How to Build a Hair Care Routine Based on Your Porosity: 7 Expert Steps
Have you ever bought a shampoo, mask, or leave-in conditioner that everyone seemed to love, only for it to do absolutely nothing for your hair? Maybe it sat on top of your strands, left your roots greasy, made your ends feel dry, or worked beautifully for one week and then stopped.
The issue may not be the product. It may be your hair porosity.
Hair porosity refers to your hair’s ability to absorb and retain moisture. Once you understand that, it becomes much easier to build a hair care routine that works with your hair instead of against it. Below, we’ll walk through 7 practical hair care routine steps based on low, medium, and high porosity hair.
What Is Hair Porosity and Why Does It Matter?
Hair porosity describes how easily moisture, oils, and products move in and out of the hair strand. The outer layer of your hair, called the cuticle, is made up of overlapping scales. When those scales are tightly packed, moisture has a harder time getting in. When they are raised or damaged, moisture may enter quickly but escape just as fast.
Most people fall into one of three categories: low, medium, or high porosity hair.
Low porosity hair tends to resist moisture.
Medium porosity hair usually absorbs and holds moisture more evenly.
High porosity hair often absorbs moisture quickly but loses it just as quickly.
According to the American Academy of Dermatology, heat styling, chemical processing, and environmental exposure can weaken the hair cuticle over time. This may affect how well hair retains moisture.
Step 1: Determine Your Hair Porosity Type
Before you buy more low porosity hair products or high porosity hair products, start by figuring out your porosity type. No at-home test is perfect, but using a few methods together can give you a better picture.
The water float test is a common starting point. Place a clean strand of shed hair in a glass of water and watch what happens after a few minutes. Hair that floats may be lower porosity, hair that settles in the middle may be medium porosity, and hair that sinks quickly may be higher porosity.
You can also try the slip-and-slide test. Run your fingers up a strand of hair from end to root. If it feels smooth, your cuticle may be more compact. If it feels rough or bumpy, the cuticle may be raised.
Finally, use the spray bottle test. Mist a small section of clean, dry hair. If water beads on top, that may suggest low porosity hair. If it absorbs almost immediately, your hair may be highly porous.
Step 2: Choose the Right Shampoo for Your Porosity
Shampoo sets the stage for the rest of your hair care routine. If your cleanser is too heavy, low porosity hair may feel coated. If it is too stripping, high porosity hair may feel dry, frizzy, and fragile.
Low Porosity Hair Care: Keep Cleansing Lightweight
Low porosity hair is more prone to buildup because products can sit on the surface instead of absorbing easily. Look for lightweight, gentle, or clarifying shampoos that remove residue without leaving a heavy coating behind. Occasional clarifying can also help conditioners and leave-ins work more effectively.
High Porosity Hair Care: Avoid Over-Stripping
High porosity hair often absorbs moisture quickly but loses it just as fast. Choose moisturizing, sulfate-free, or bond-supportive shampoos that cleanse without leaving hair feeling rough or depleted. Harsh shampoos can make dryness, frizz, and breakage more noticeable.
Medium Porosity Hair Care: Stay Balanced
Medium porosity hair usually does well with a balanced shampoo that cleanses without stripping. You may only need to adjust your shampoo based on oil production, styling habits, color services, or seasonal dryness.
For all porosity types, lukewarm water is a smart choice. Very hot water can leave hair feeling drier, especially if your hair is already color-treated or heat-styled.
Step 3: Master the Conditioning Process
Conditioning is where porosity really starts to matter. The goal is not simply to “add moisture.” It helps your hair accept and retain the right amount of moisture.
Low Porosity Hair Routine: Use Warmth and Lighter Formulas
Low porosity hair often needs help letting moisture in. Lightweight conditioners, steam from the shower, and a few extra minutes of processing time can make a difference. Avoid using thick masks too often if they leave your hair stiff, waxy, or limp.
High Porosity Hair Routine: Focus on Moisture Retention
High porosity hair may need richer conditioners and regular deep conditioning treatments. Since the cuticle is more open, these formulas can smooth the hair, reduce moisture loss, and make strands feel softer between wash days.
Medium Porosity Hair Routine: Keep It Steady
Medium porosity hair usually responds well to a regular rinse-out conditioner and occasional deep treatment. If your hair starts feeling weighed down, scale back. If it feels dry, tangled, or dull, add more conditioning support.
Step 4: Select Moisturizers and Leave-In Products
This is where many routines go sideways. A product may be excellent, but still wrong for your porosity, density, or texture.
Low Porosity Hair Products: Choose Light Layers
Low porosity hair often does best with water-based leave-ins, lightweight milks, soft gels, and minimal layering. Heavy butters or thick oils may sit on top of the hair, so start with a small amount and add only if needed.
High Porosity Hair Products: Add Moisture and Seal It In
High porosity hair often benefits from leave-in conditioners, creams, butters, and sealing oils that slow moisture loss. Since this hair type tends to absorb products quickly, richer layering may be helpful, especially on dry ends.
Medium Porosity Hair Products: Keep the Routine Simple
Medium porosity hair usually has more flexibility. A simple leave-in conditioner and styling product may be enough, with heavier products added only when your hair feels dry or needs more control.
You may also hear about the LOC method (liquid, oil, cream) and the LCO method (liquid, cream, oil). Many low porosity routines do better with lighter versions of these methods, while high porosity routines may benefit from richer layering. Start with fewer products, then add only what your hair seems to need.
Step 5: Incorporate Protein Treatments Wisely
Protein can support strength, structure, and resilience, especially for hair that has been colored, lightened, chemically treated, or heat-styled. However, protein is not something every hair type needs in the same amount.
Low porosity hair may be more sensitive to frequent protein treatments. Too much protein can leave it feeling stiff, straw-like, brittle, or prone to snapping.
High porosity hair often benefits from occasional protein because raised or damaged cuticles may need extra support. Still, balance matters. Too much protein can make hair rigid, while too much moisture can make it feel limp, gummy, mushy, or overly stretchy.
Medium porosity hair may only need protein occasionally, especially after color services or heat exposure. This is one of the most overlooked hair-care routine tips: healthy hair needs both moisture and strength, not just one or the other.
Step 6: Adjust Your Styling Techniques
Your styling habits can support your hair routine or undo the progress you are making.
Low Porosity Hair Routine: Style in Thin Layers
Apply products to damp hair in thin layers. If your products sit on top, try using less product, adding more water, or styling in smaller sections. Lightweight foams, gels, or creams may be easier to manage than dense formulas.
High Porosity Hair Routine: Protect Against Moisture Loss
Apply leave-in products while your hair is still wet, then seal as needed. Protective styles, gentle detangling, and low-friction drying methods can reduce breakage and keep the hair feeling softer for longer.
Medium Porosity Hair Routine: Adjust by Season and Styling Habits
Medium porosity hair often stays fairly balanced, but your routine may need small changes depending on the weather, color services, or heat styling. If your hair starts feeling dry, increase moisture. If it feels heavy, simplify your products.
Step 7: Stay Consistent and Adjust as Needed
A new hair care routine needs time. Give your routine at least four to eight weeks before deciding whether it works, unless a product causes irritation, breakage, or heavy buildup right away.
A simple hair journal can help you track wash days, products, drying time, frizz, softness, and breakage. Porosity can also change over time, especially after coloring, bleaching, chemical treatments, heat styling, or environmental exposure. Reassess your hair every few months.
Most importantly, be patient with yourself. What works for someone else may not work for you, and that does not mean your hair is difficult. It means your routine needs to match your hair.
Build a Hair Care Routine That Works with Your Hair
Understanding hair porosity can transform your hair care routine from frustrating guesswork into a more thoughtful, science-based process. Low porosity hair, medium porosity hair, and high porosity hair each need a different approach to cleansing, conditioning, moisturizing, protein, and styling.
