You oil your hair twice a week. You use what everyone recommends, coconut oil, castor oil, maybe a mix of both. Your hair feels coated, heavy, and somehow drier than before you started. You have probably wondered whether you are doing something wrong.
You are. But it is not the oiling. It is the oil.
Low porosity hair has tightly closed cuticles that block most of the oils Pakistani women reach for by default. When a heavy oil cannot enter the hair shaft, it does not condition, it coats. And a coat of oil on closed cuticles is the opposite of what your hair needs: it traps dryness inside and locks moisture out.
This article explains exactly why this happens at the molecular level, which specific oils make low porosity hair worse, which lightweight alternatives actually penetrate, and how to apply them correctly so they do more than sit on the surface.
What Is Hair Porosity and How Do You Know If Yours Is Low?
Hair porosity describes how easily your hair shaft absorbs and retains moisture. It is determined by the structure of your cuticle layer, the outermost layer of the hair strand, made up of overlapping protein scales (like roof shingles) that open and close to allow moisture in and out.¹
There are three porosity levels. Understanding which applies to you changes everything about how you should care for your hair.
💧 Low Porosity
Cuticles are tightly closed and flat. Moisture struggles to enter. Products sit on the surface. Hair takes long to get wet and dry. Prone to build-up.
✅ Medium Porosity
Cuticles are slightly raised. Moisture enters and leaves at a normal rate. Hair is easy to style, holds colour well, and responds to most products.
🌊 High Porosity
Cuticles are raised or damaged. Moisture enters quickly but leaves just as fast. Hair feels dry despite frequent oiling. Prone to frizz and breakage.
How to Test Your Hair Porosity at Home
The simplest method is the float test: drop a clean, product-free strand of hair into a glass of room-temperature water.
Floats for a long time before sinking → Low porosity. The closed cuticles resist water entry, so the strand stays buoyant.
Sinks slowly to the middle → Medium porosity. Normal moisture exchange.
Sinks immediately to the bottom → High porosity. The open cuticles absorb water rapidly.
Other signs of low porosity hair beyond the float test: water beads on the surface when you wet it rather than soaking in immediately; products leave white residue or roll off rather than absorbing; your hair takes 2 to 3 hours to air dry even though it feels thick. All of these are signs of a tightly closed cuticle, not a hair strand lacking moisture. The two are different problems requiring different solutions.
Low porosity is extremely common in Pakistani hair types:
Straight and wavy hair tends to have naturally tighter cuticles than tightly coiled hair. Many Pakistani women with straight or slightly wavy hair are unknowingly low porosity, which is why the heavy oils recommended in traditional South Asian hair care (coconut, castor, mustard) do not work for them the way they work for others, and why their hair often feels worse after oiling than before.
The Molecular Science: Why Heavy Oils Cannot Penetrate Closed Cuticles
This is the part most hair care articles skip, and it is the part that actually explains everything. The difference between an oil that works for low porosity hair and one that makes it worse is not about "natural" vs "synthetic." It is about molecular size and fatty acid composition.²
Every carrier oil is composed primarily of fatty acids, long-chain carbon molecules. The two most relevant to hair care are:
Oleic Acid (Omega-9): The Heavy Molecule
18-carbon monounsaturated chain. Relatively large molecular diameter. Penetrates open cuticles well. Cannot slip into tightly closed cuticle gaps. Sits on the surface of low porosity hair and forms a coating barrier. Oils high in oleic acid: coconut (~47%), olive (~70%), castor, avocado.
Linoleic Acid (Omega-6): The Light Molecule
18-carbon polyunsaturated chain. Smaller effective molecular diameter due to double bonds creating a bent structure. Can penetrate more tightly closed cuticle gaps. Oils high in linoleic acid: grapeseed (~73%), rosehip (~38%), hemp seed (~57%), sunflower (~65%).
A landmark study published in the Journal of Cosmetic Science by Rele and Mohile² tested the penetration of coconut oil, sunflower oil, and mineral oil into the hair shaft. The study found that coconut oil significantly reduced protein loss from hair, but this effect was most pronounced in high porosity hair where the cuticle is open enough to allow entry. In tighter cuticle structures, the larger molecules fail to penetrate and remain on the surface.
A second factor is viscosity, the thickness of the oil. Castor oil has one of the highest viscosities of any carrier oil. Even if the molecular composition were right, its physical thickness prevents it from flowing into the narrow gaps between low porosity cuticle scales. This is why castor oil leaves low porosity hair with the stiff, weighted texture that so many Pakistani women describe when they say oiling makes their hair worse.
Oils That Make Low Porosity Hair Worse and Why
These are the oils most commonly used in Pakistani hair care routines, and the ones most likely to be working against low porosity hair rather than for it. This is not a claim that these oils are bad in general. They are excellent oils for the right hair type. The problem is matching the oil to the cuticle structure.
Castor Oil
~90% ricinoleic acid, extremely high viscosity
The most viscous common carrier oil. Physically cannot enter tight cuticle gaps. Forms a thick coating layer that traps dryness inside, prevents water absorption, and causes severe build-up. May be used on the scalp only, not the hair shaft for low porosity types.
Zaitoon (Olive) Oil
~70–75% oleic acid
The highest oleic acid content of common carrier oils. Excellent for high porosity and dry hair. The large oleic acid molecules penetrate well where cuticles are open. On low porosity hair, the same molecules sit on the surface as a dense, heavy coating. See our guide on zaitoon oil: benefits, limits and how to use it.
Mustard (Sarson) Oil
~60% erucic acid, high oleic, thick and viscous
High erucic acid content and heavy viscosity make it unsuitable for low porosity strands. The physical thickness alone means it will not enter closed cuticle gaps. Acceptable on the scalp for circulation benefits; problematic on hair lengths.
Avocado Oil
~70% oleic acid
Similar profile to olive oil. Very high oleic acid makes it excellent for high porosity and damaged hair but too heavy for closed cuticles. Often marketed as "deeply penetrating." It is, but only for hair types with sufficiently open cuticles to allow entry.
Bhringraj Oil (infused in coconut base)
Depends on carrier, usually coconut or sesame
The herbal actives in bhringraj are beneficial, but most commercial bhringraj oils in Pakistan use coconut oil as their carrier, which reintroduces the heavy molecule problem on low porosity strands. Choose bhringraj infused in a lighter carrier (sesame or grapeseed) or apply only to the scalp. See our bhringraj oil guide for how to choose wisely.
Taramira (Jamba) Oil
~22–45% erucic acid, pungent and moderately thick
Taramira's active compounds (isothiocyanates) are scalp-focused and antifungal, which means its most valuable work happens at the scalp level anyway, not on the hair shaft. It is better suited for scalp treatment than hair strand conditioning in low porosity types. Read more in our taramira oil guide.
The build-up cycle to watch for:
When a heavy oil cannot penetrate the cuticle, it does not just sit there harmlessly. It accumulates with each application. This build-up progressively seals the cuticle more, making it even harder for moisture to enter over time. Many Pakistani women who describe their hair getting progressively drier despite consistent oiling are experiencing this exact build-up cycle. The solution is not more oil. It is a clarifying wash followed by a switch to lighter oils.
Oils That Actually Work for Low Porosity Hair and Why
The oils that work for low porosity hair share one property: they are high in linoleic acid or other small-molecule fatty acids that can slip between tightly packed cuticle scales without requiring the cuticle to open. Some also mimic the scalp's natural sebum in their composition, which the hair shaft accepts more readily.
Jojoba Oil (Simmondsia chinensis): The Sebum Mimic
Jojoba is technically not an oil. It is a liquid wax ester, which means its chemical structure is closer to the scalp's own sebum than any other plant-derived substance. Because the hair follicle already produces a sebum-like compound, jojoba is accepted by the hair shaft without triggering the same cuticle resistance that other oils encounter.¹ It absorbs without leaving a greasy film, moisturises without build-up, and does not require a fully open cuticle to deliver benefit.
Jojoba is the closest thing to a universal low porosity hair oil. It is lightweight enough for tightly closed cuticles, has a long shelf life, and is available in Pakistan through specialty organic stores and online platforms.
Grapeseed Oil: The High-Linoleic Penetrator
Grapeseed oil contains approximately 73% linoleic acid, one of the highest linoleic concentrations of any carrier oil. Its small, bent molecular structure allows it to slip between closed cuticle scales and deliver conditioning at the cortex level rather than sitting on the surface. It is extremely light in texture, absorbs quickly, and leaves no greasy residue. It is also rich in Vitamin E and polyphenolic antioxidants that support the scalp environment. In Pakistan, grapeseed oil is available at most health stores and pharmacies.
Rosehip Oil: Light, Antioxidant-Rich
Rosehip oil contains approximately 38% linoleic acid alongside trans-retinoic acid (a form of Vitamin A) and tocopherols. It is lighter than most carrier oils and absorbs without residue. While it is more commonly marketed for skin, its fatty acid profile makes it suitable for low porosity hair conditioning, particularly when hair fall is also being driven by scalp-level oxidative stress. A few drops to the mid-lengths and ends after washing is the most effective protocol.
Argan Oil (Moroccan Oil): Light and Balancing
Argan oil contains approximately 43% oleic acid and 37% linoleic acid, a more balanced profile than olive or coconut, with enough linoleic acid to offer meaningful penetration in low porosity hair. It is not as light as grapeseed or jojoba, but its Vitamin E content and the balance of fatty acids make it the most manageable of the "heavier" light oils for low porosity types. Use it in small quantities, a few drops, to avoid the surface coating effect of its oleic acid fraction.
Hemp Seed Oil: Anti-Inflammatory and Light
Hemp seed oil contains approximately 57% linoleic acid and 17% alpha-linolenic acid (Omega-3). Its high polyunsaturated fatty acid content makes it one of the lightest-absorbing carrier oils available. It also has documented anti-inflammatory properties for the scalp, useful if low porosity hair fall is partly driven by scalp inflammation. It is available in Pakistan through organic health retailers.
Sesame Oil (Til Oil): The Traditional Light Option
Sesame oil contains approximately 45% oleic acid and 43% linoleic acid, a near-equal split that makes it more balanced than most traditional Pakistani oils. It is significantly lighter than coconut or castor oil, absorbs more readily, and has been used in traditional South Asian hair care for centuries. For low porosity Pakistani hair, sesame oil is the most culturally familiar and locally accessible option.

How to Oil Low Porosity Hair Correctly: The LCO Method
Choosing the right oil is half the solution. The other half is application method. The LCO method (Liquid-Oil-Cream) is the most widely documented effective protocol for low porosity hair because it addresses the core challenge: there is no point sealing moisture with oil if there is no moisture present to seal.
Liquid: Apply Water or Leave-in Conditioner First. Start on damp, freshly washed hair or mist with water until the hair is damp throughout. Alternatively, apply a water-based leave-in conditioner. This step puts moisture inside the hair shaft. This is the entire point of the oil step that follows. Applying oil to dry low porosity hair seals nothing because the shaft is already empty of moisture.
Oil: Apply a Lightweight Oil While Still Damp. While the hair is still damp from Step 1, apply a small amount of one of the lightweight oils recommended above, grapeseed, jojoba, or sesame. Work it through the mid-lengths and ends, not the scalp. Use sparingly: half a teaspoon for fine hair, 1 teaspoon for thick hair. The oil seals the water moisture inside the shaft rather than allowing it to evaporate.
Cream: Optionally Lock With a Light Butter or Cream. For very fine hair, the oil step alone is usually sufficient. For thicker low porosity hair, a light leave-in cream or hair butter applied over the oil layer adds a third layer of moisture locking. This is the C in LCO. Avoid heavy butters (shea butter, mango butter). They carry the same large-molecule problem as heavy oils for low porosity types.
Heat: Open the Cuticle for Deeper Penetration (Optional But Effective). After applying your lightweight oil, wrap the hair in a warm, damp towel for 15 to 20 minutes. The gentle heat physically opens the cuticle scales slightly, allowing the small oil molecules to penetrate deeper into the cortex layer rather than just sealing the surface. This step makes a measurable difference for stubborn low porosity hair. A hooded dryer achieves the same effect. Do not use high direct heat. The goal is gentle warmth, not damage.
Clarify Weekly to Reset the Build-up Baseline. Even lightweight oils accumulate on low porosity cuticles over time if not regularly removed. Use a mild clarifying wash (sulphate-free or low-sulphate shampoo) once a week to clear residue from the cuticle surface. This keeps the cuticle surface clean so moisture can continue to enter during your next application. Skipping this step gradually recreates the same build-up problem that heavy oils cause from the start.
A quick note on hair fall and porosity:
Low porosity hair that has accumulated heavy oil build-up often experiences increased hair fall, not because of the porosity itself, but because the build-up blocks scalp pores, traps sebum, and creates an environment for follicle inflammation. If your hair fall increased when you started heavy oiling, porosity-related build-up may be a contributing factor. See our guide on why hair falls out: 7 causes and what actually fixes each to identify whether this applies to your situation.
A Note on Herbal Hair Oil Formulas and Low Porosity Hair
Most commercially available herbal hair oils in Pakistan, including many multi-herb formulas, use coconut oil or castor oil as their carrier base. This means even if the herbal actives inside them are genuinely effective (bhringraj, rosemary, amla, taramira), the delivery mechanism is wrong for low porosity hair. The herbal compounds never reach the follicle level because the carrier molecules are too large to penetrate the cuticle.
What low porosity hair needs is a herbal formula built on a light carrier base, sesame, grapeseed, or a jojoba-blended base, so that the active ingredients can actually reach the scalp and follicle rather than sitting on the cuticle surface.
Attari Herbal's 11+12 formula incorporates sesame oil as a carrier component, one of the lighter traditional Pakistani oils, with a near-equal oleic and linoleic profile that makes it significantly more suitable for low porosity types than coconut or castor-based alternatives. It is not a formula designed exclusively for low porosity hair, but its lighter carrier base makes it more compatible than most Pakistani herbal oils on the market.

FAQs
What is low porosity hair?
Low porosity hair has a tightly closed cuticle layer, the overlapping protein scales that cover the outer surface of each hair strand. Because the cuticles lie flat with very little space between them, moisture, water, and oil molecules have difficulty entering the hair shaft. Low porosity hair is often genetic and is more common in straight and fine hair types, including many Pakistani hair types.¹
How do I know if I have low porosity hair?
The simplest test is the float test: drop a clean strand of hair into a glass of room-temperature water. Low porosity hair floats for a long time before sinking, because tightly closed cuticles resist water entry. Other signs: water beads on your hair surface rather than soaking in; products leave residue rather than absorbing; hair takes 2 to 3 hours to air dry even though it feels thick; hair feels coated and heavy after oiling with small amounts.
Why does coconut oil make my hair worse?
Coconut oil is approximately 47% lauric acid, a fatty acid molecule that penetrates high porosity hair well but sits on the surface of tightly closed low porosity cuticles. Because it cannot enter the hair shaft, it forms a coating that traps dryness inside and blocks moisture from entering. With repeated use, it builds up progressively, making hair feel increasingly stiff and dull.²
What is the LCO method and does it work for low porosity hair?
The LCO method (Liquid-Oil-Cream) is a layered moisture retention technique. For low porosity hair: apply water or leave-in conditioner to damp hair first (L), then seal it with a small amount of lightweight oil (O), then optionally lock it in with a light cream (C). It works because it ensures moisture is inside the shaft before the oil seals it. Applying oil to dry low porosity hair seals nothing because there is no moisture present to retain.
Is castor oil bad for low porosity hair?
Yes, on the hair shaft. Castor oil is one of the most viscous carrier oils available. It cannot penetrate closed cuticles and instead forms a dense surface coating that blocks moisture, causes build-up, and gives a heavy, straw-like texture. It may be used on the scalp only, where its ricinoleic acid provides anti-inflammatory benefit without the need to penetrate cuticle scales.
Can I use herbal hair oils if I have low porosity hair?
Yes, but only if the herbal oil formula uses lightweight carrier oils rather than heavy bases like castor, coconut, or olive. A well-formulated herbal oil using sesame, grapeseed, or jojoba as its carrier can deliver herbal actives to the scalp without coating the hair shaft with large molecules. Check the carrier oil base, not just the herbal ingredients listed. Most herbal oils marketed in Pakistan use coconut or castor as their base, which reintroduces the heavy molecule problem for low porosity hair.
