Your Hair Isn't Rejecting Every Product. You May Be Treating the Wrong Porosity
Your Hair Isn't Rejecting Every Product. You May Be Treating the Wrong Porosity
You've bought the moisturising shampoo. You've tried the expensive mask. You've added oils, leave-in conditioner and the treatment everyone online seems to love.
Yet your hair still doesn't feel right.
Maybe products sit on the surface and leave your hair heavy. Perhaps your hair seems to absorb everything you apply but somehow feels dry again shortly afterwards.
After enough disappointing products, it's easy to start thinking your hair is simply "difficult."
But the problem may not be your hair. It may be that your routine isn't taking hair porosity into account.
At Cocco Salon in Derby, our Prescriptive approach is built around understanding how your individual hair behaves. Porosity can be one useful part of that picture, particularly when you're frustrated by products that never seem to deliver what they promise.
What Is Hair Porosity?
Hair porosity describes how readily your hair absorbs and retains water and other substances.
The outer surface of each strand is called the cuticle. How compact or compromised that cuticle is can influence how readily water and products move into and out of the hair fibre.
Porosity is commonly discussed in three broad categories:
Low porosity: moisture and products can have more difficulty penetrating the hair
Medium porosity: the hair generally absorbs and retains moisture more evenly
High porosity: moisture can enter readily but may also be lost more quickly
These categories aren't about whether your hair is "good" or "bad." They simply help explain why two people can use exactly the same product and experience completely different results.
Why Does Porosity Matter?
Have you ever bought a product because someone's hair looked incredible after using it, only to wonder why it did absolutely nothing for yours?
Porosity could be part of the explanation.
Low-porosity hair has a more compact cuticle structure, which can make it harder for water and products to penetrate. High-porosity hair has a more permeable structure, so it can absorb moisture quickly but may struggle to retain it.
That means the richest mask isn't automatically the most moisturising choice for every person.
Sometimes the issue isn't that you need more product.
You need a product and routine better suited to the way your hair behaves.
Signs Your Hair May Have Lower Porosity
Lower-porosity hair can sometimes feel confusing because it may seem dry while simultaneously becoming coated by products.
You might notice:
Water seems to sit on the hair initially
Your hair takes time to become fully saturated
Rich products appear to remain on the surface
Oils or creams quickly make your hair feel heavy
Product build-up becomes noticeable
Your hair takes a relatively long time to dry
Recent professional guidance describes low-porosity hair as having a tightly compact cuticle structure that slows the absorption of water, oils and treatment ingredients.
If you've responded to dryness by continually adding richer products, you may actually be making your hair feel heavier without solving the underlying frustration.
Why More Moisture Isn't Always the Answer
This is where clients can become understandably frustrated.
Your hair feels dry, so you buy a richer mask. It still feels dry, so you add an oil. Then a leave-in. Then another treatment.
Eventually, your hair feels coated, flat and greasy, yet somehow still doesn't feel properly hydrated.
For lower-porosity hair, lightweight and appropriately layered hydration may work better than repeatedly coating the strand in heavy formulas. Recent haircare guidance similarly emphasises lighter formulations for low-porosity hair to help avoid unwanted build-up.
Sometimes simplifying your routine can be more effective than adding another product.
What About High-Porosity Hair?
High-porosity hair presents almost the opposite frustration.
Your hair may seem to absorb water and products readily, but softness doesn't last. It can begin feeling dry again surprisingly quickly.
You might experience:
Persistent dryness
Roughness through the lengths
Increased frizz
Tangling
Reduced shine
Difficulty retaining moisture
Increased vulnerability to breakage
Higher porosity can be related to the natural characteristics of the hair, but chemical processing, repeated heat and other forms of environmental or mechanical stress can also compromise the cuticle over time.
This is why your colour and styling history matter when we assess what your hair needs.
Colouring Can Change the Conversation
Perhaps your hair didn't always behave this way.
Maybe your natural hair was relatively easy to manage, but after repeated highlighting, lightening or heat styling, your lengths now feel completely different from your roots.
That is possible because different sections of the same head of hair can have different histories.
Your newer growth may be relatively untouched, while the mid-lengths have been coloured several times and the ends have experienced years of colouring, heat, washing and styling.
Your haircare routine needs to recognise those differences.
One Head of Hair Can Have Different Needs
This is also why putting a single label on your entire head can sometimes be misleading.
Your roots may behave differently from your ends. Previously lightened sections may respond differently from untouched hair.
You could therefore find that one product feels perfect in one area and too heavy or insufficient in another.
At Cocco Salon, we prefer to look at the complete history of your hair rather than trying to fit every strand neatly into one category.
Stop Buying Products Based Only on Someone Else's Hair
Social media makes product recommendations incredibly persuasive.
Someone applies a mask and suddenly their curls look beautifully defined. Another person uses an oil and achieves an incredibly glossy finish.
You buy the same product.
Your hair looks nothing like theirs.
That doesn't automatically mean the product is bad. Their texture, density, porosity, colour history and condition may simply be completely different from yours.
Before buying another viral recommendation, ask whether the person recommending it actually has hair that behaves anything like your own.
Could Build-Up Be Confusing the Issue?
Yes.
Product accumulation can make it harder to understand what your hair actually needs, particularly when rich products are repeatedly layered onto hair that is easily weighed down.
Low-porosity hair, in particular, can be prone to products remaining on the surface rather than absorbing efficiently.
If your hair feels simultaneously heavy, coated and unsatisfied, adding more oil or another mask may not be the best first response.
Your routine may need simplifying or your cleansing routine may need reassessing.
What About the Hair Porosity Float Test?
You may have seen the popular test where a strand of hair is placed into a glass of water.
The idea is that floating hair indicates lower porosity while hair that sinks suggests higher porosity.
Although this can offer a rough indication, professional assessment considers more than a single strand in a glass. L'Oréal Professionnel notes that observing how hair wets, dries and absorbs products can be more reliable than relying on a float test alone.
Your hair history and how it behaves in everyday life provide valuable information too.
Signs Your Current Routine May Not Suit Your Hair
You don't need to become an expert in hair science before recognising that something isn't working.
Consider reassessing your routine if:
Products consistently sit on your hair rather than seeming to absorb
Your hair becomes heavy immediately after conditioning
Your lengths feel dry shortly after applying moisturising products
You constantly switch products without seeing improvement
Your hair tangles or feels rough despite regular conditioning
Your roots and ends respond completely differently
Your hair has changed significantly following repeated colouring or heat styling
These signs don't diagnose your porosity by themselves.
They simply suggest that a more personalised approach may be useful.
Your Haircare Routine Should Solve Problems, Not Create New Ones
A good routine doesn't need to contain ten different products.
If your shampoo leaves your hair uncomfortable, your conditioner makes it heavy and your styling products create more build-up than manageability, the answer may not be adding another treatment.
Sometimes the most effective change is understanding what each product is supposed to achieve.
For some hair, lightweight hydration may be appropriate. Other hair may need richer conditioning and greater support for moisture retention. Medium-porosity hair may respond well to a more balanced routine.
The important word is appropriate.
Our Prescriptive Approach Takes the Guesswork Out of Haircare
At Cocco Salon, we don't recommend products simply because they're popular.
We consider factors including:
Hair texture
Density
Porosity and absorption behaviour
Current condition
Colour history
Heat styling habits
Product build-up
Natural movement
Lifestyle
Your biggest frustrations
Most importantly, we listen to what is actually happening when you style your hair at home.
If your products aren't working, we want to understand why before recommending more of them.
You Don't Need a Bigger Bathroom Shelf
There is something exhausting about repeatedly spending money on products that end up pushed to the back of the cupboard.
It can also make you lose confidence in your own ability to care for your hair.
But your hair isn't failing because it didn't respond to a product that worked beautifully for someone else.
It may simply need a different approach.
Understanding porosity can help explain why certain formulas feel too heavy, why others don't provide enough lasting softness and why your hair's needs may have changed after years of colouring or styling.
Better Haircare Starts with Understanding Your Hair
Hair porosity isn't another beauty rule you need to obsess over.
It is simply one more piece of information that can help make your routine more personalised.
Once you understand how your hair absorbs and retains moisture, choosing products becomes less about following trends and more about solving the problems you're actually experiencing.
That can mean fewer disappointing purchases, less trial and error and a routine that finally feels manageable.
Most importantly, it can help replace frustration with confidence.
Your hair doesn't need every product.
It needs the right approach for your hair.
