How do you feel when you’re having a great hair day? 

There’s an undeniable sense of confidence that comes with hair that looks and feels healthy, whether it’s effortlessly falling into place, exuding shine, or simply behaving the way you want it to. On those days, you feel good, and let’s admit it, that energy carries into everything you do.

But then there are the other days. The ones where your hair feels like it has a mind of its own, frizzy, dry, or flat, refusing to cooperate no matter how many products you use.

Why does this happen? 

Why does hair health seem so unpredictable?

The truth is, it all starts at the root—literally. 

While we are often conditioned to focus on the hair strand itself, real hair health begins with scalp care. Just like rich, nourished soil is essential for healthy plant growth, a well-balanced scalp is the foundation for strong, beautiful hair. And this is where we need to talk about scalp pH, hydration, and how simple, natural practices can make all the difference.

I have an 82-year-old hippie friend, who has lived most of his life by the sea, deeply connected with nature. He has never used shampoo. No fancy hair masks, no serums—just water. And yet, his hair is thick, strong, and full of life. 

How? 

Because his scalp has never been stripped of its natural oils. His lifestyle, nutrition, and minimal approach to hair care have allowed his scalp to regulate itself naturally, maintaining the perfect balance without external interference.

Now, does this mean you should throw away your shampoo? 

Not necessarily. 

We live in a world filled with pollution, sweat, and product buildup, so simply rinsing with water may not be practical for everyone. 

But what we can learn from him is that less is often more. Understanding how to work with the natural ecosystem of your scalp instead of against it is the real secret to healthy, shiny hair.

And this is exactly what we are going to uncover—how maintaining scalp pH, choosing the right hair care practices, and making a few simple but effective changes can transform the way your hair looks and feels. 

 

The Science of Scalp pH: Why It Matters More Than You Think

Most people focus on finding the perfect shampoo or hair mask, but how often do we think about our scalp’s pH balance? Like our gut and skin, the scalp has a natural pH level that is crucial to its overall health. 

A balanced scalp means healthier, shinier, and stronger hair. But when that balance is thrown off, we invite a host of issues—dryness, oiliness, dandruff, itchiness, and even hair fall.

Scalp pH Explained

Science tells us that the ideal pH for a healthy scalp falls between 4.5 and 5.5—slightly acidic. This acidity is essential because it acts as a protective barrier, keeping bacteria, fungi, and other harmful microbes in check. It also ensures that the scalp retains just the right amount of natural oils (sebum), preventing it from becoming too dry or excessively greasy.

A well-balanced scalp supports the hair cuticle, ensuring that each strand remains smooth, strong, and less prone to breakage. When this balance is disrupted, the scalp becomes vulnerable to inflammation, irritation, and even conditions like seborrheic dermatitis and dandruff.

In my recent conversation with Dr. Sonali Kohli, an Integrative Aesthetic Dermatologist, and Hair Transplant Surgeon, she emphasized how an imbalanced scalp pH could be one of the biggest culprits behind persistent scalp issues. Many people use anti-dandruff shampoos or expensive treatments without realizing that the real issue might just be the pH imbalance caused by everyday habits.

She explained how a disrupted scalp barrier can lead to fungal overgrowth, increased oil production, or excessive dryness, depending on whether the pH has gone too high (alkaline) or too low (overly acidic).

So, what causes these imbalances? And how can we fix them?

 

What Disrupts the Scalp pH?

  1. Harsh Shampoos & Chemical Products: Many commercial shampoos contain sulfates, parabens, and alcohol-based ingredients that strip away the scalp’s natural oils. While they may leave hair feeling clean, they also disrupt the pH, making the scalp more alkaline. This can lead to the overproduction of sebum (making hair greasy) or excessive dryness (leading to flakiness and irritation).
  2. Excessive Heat: Love those long, hot showers? Or styling your hair with a blow dryer regularly? Heat can disrupt scalp moisture levels, stripping away its natural barrier and pushing the pH toward an unhealthy range. A hot shower may feel great at the moment, but it can leave your scalp irritated, dry, and more prone to itching or dandruff.
  3. Overwashing vs. Underwashing: There’s a fine balance between washing your hair too often and not washing it enough. Overwashing, especially with harsh shampoos, removes natural oils, forcing the scalp to overcompensate by producing more oil. This leads to greasy hair and clogged follicles, potentially triggering hair fall. On the other hand, underwashing allows sweat, dirt, and product buildup to accumulate, leading to scalp inflammation and odor.

4. Wearing Shower Caps Daily: This one is often overlooked. Many people wear shower caps every day to avoid wetting their hair, but doing this traps steam and moisture, creating a warm, damp environment that promotes fungal growth. A humid scalp can alter its natural pH and lead to issues like flakiness, itching, and even scalp acne.

 

Dandruff vs. Flaky Scalp: Understanding the Root Cause

Have you ever noticed white flakes on your shoulders and immediately assumed it was dandruff? 

Most people do.

But not all flaking is dandruff. 

Sometimes, what we think is dandruff is actually a dry, flaky scalp caused by an entirely different issue. 

The problem? 

Treating it the wrong way can make things worse.

So, let’s break it down: Is it dandruff, or just a flaky scalp?

 

The Difference Between Dandruff and Flaky Skin

Many people use the words ‘dandruff’ and ‘flaky scalp’ interchangeably, but they are not the same. The treatment for each is different, which is why it’s so important to understand the difference.

Dandruff: A Fungal Infection, Not Just Dry Skin

Dandruff is caused by an overgrowth of a naturally occurring fungus called Malassezia. This yeast-like fungus is always present on our scalp, but when conditions are right, especially when there’s excess oil (sebum), it multiplies rapidly, leading to irritation, itching, and flaking.

Dandruff is not due to a lack of hygiene but is a reaction to excessive yeast growth, which causes the scalp to shed skin at a faster rate than usual. The flakes from dandruff tend to be oily, yellowish-white, and clump together, and they are often accompanied by an itchy, irritated scalp.

Flaky Scalp: More Than Just Dryness

A flaky scalp, on the other hand, is usually a sign of skin conditions like dermatitis, eczema, psoriasis, or even product allergies. Unlike dandruff, which is caused by fungus, flaky scalp issues are often linked to an impaired skin barrier, excessive dryness, or inflammation.

If your flakes are dry, smaller, and white, and if your scalp feels tight and rough, you might just have dry skin rather than dandruff. Sometimes, an overly aggressive haircare routine, using shampoos with harsh sulfates, frequent heat styling, or even hot showers, can strip away the scalp’s natural oils, leading to excessive dryness and flaking. 

As Dr. Kohli pointed out in our conversation, “The yeast that causes dandruff feeds on oil. The more oil you apply, the more food you give to the fungus, making dandruff worse, not better.” This is why simply oiling the scalp is not a solution for dandruff.

She also explained that people often reach for anti-dandruff shampoos without addressing the root cause. While medicated shampoos containing ketoconazole, zinc pyrithione, or selenium sulfide can help control fungal growth, they need to be used correctly, and not all the time. Overuse can lead to dryness, which then creates another set of problems.

The bottom line? 

If you have dandruff, oiling your scalp excessively won’t help. If you have a flaky scalp due to dryness, using anti-dandruff products might strip away essential moisture, making the condition worse.

Disclaimer: Before attempting any self-treatment, it is essential to identify the root cause of your scalp condition. Dandruff and flakiness may look similar but have different underlying causes that require specific treatments. Consult a qualified dermatologist to get an accurate diagnosis and the right course of action for your scalp health.

 

The 5 Essential Scalp Care Tips for Healthy, Strong Hair

1. Maintain a Healthy Scalp pH

  • Use a pH-balanced shampoo—preferably sulfate- and paraben-free—to maintain scalp health.
  • Avoid hot water while washing your hair. Instead, use lukewarm or cool water to prevent excessive drying of the scalp.
  • Rinse your hair with rice water once a week. Rich in inositol, rice water strengthens hair, reduces surface friction, and helps maintain a healthy pH balance.

2. Choose Cold-Air Drying Over Heat Styling

If you frequently use heat styling tools or blow-dry your hair with hot air, you could be damaging your hair’s protein structure without realizing it.

Why Cold-Air Drying is a Game-Changer?

  • Traditional hot-air drying weakens the hair shaft and leads to moisture loss.
  • Cold-air drying reduces heat damage, locks in moisture, and enhances shine.
  • If using a dryer, keep it at a safe distance from your hair to prevent excessive dryness.
  • Avoid vigorous towel-drying—rubbing wet hair with a rough towel increases friction and leads to breakage. Instead, use a microfiber towel or a soft cotton t-shirt to gently absorb excess water.
  • Use a wide-tooth comb or a specialized brush designed for wet hair to prevent unnecessary breakage.
  • If you have long hair, consider wrapping it in a soft turban before using a cold-air dryer—this helps to reduce direct exposure while still allowing effective drying.

3. Oil Your Hair, But Not Overnight

Oiling is an ancient and effective practice, but there’s a right way and a wrong way to do it. Just like a conditioner seals the hair cuticle, oil creates a hydrophobic barrier that prevents excessive water loss, keeping your hair hydrated and healthy. But many people leave oil on their scalp overnight, believing it nourishes the hair better. However, excessive overnight oiling can disrupt the scalp’s pH, clog follicles, and worsen dandruff. 

Instead:

  • Apply oil 20-30 minutes before washing—this gives your scalp just enough time to absorb nutrients without causing excessive buildup.
  • Use lightweight oils like coconut, almond, or jojoba to prevent scalp congestion.

4. Exfoliate Your Scalp for Healthy Hair Growth

Most people focus on exfoliating their face and body but forget that the scalp also needs exfoliation. Over time, product residue, pollution, dead skin cells, and excess oil clog hair follicles, leading to slower hair growth and scalp issues.

Why is exfoliation essential?

  • Removes buildup, allowing follicles to breathe and function optimally.
  • Boosts blood circulation, which nourishes hair roots and supports new hair growth.

How to do it?

  • Use a salt scrub, coffee scrub, or a gentle scalp exfoliator once a week to cleanse the scalp naturally. 

Disclaimer: Always patch-test any scrub or exfoliant before applying it to your entire scalp, especially if you have a sensitive scalp or existing conditions like eczema, psoriasis, or dermatitis. Over-exfoliation can lead to irritation, dryness, or increased oil production as the scalp tries to compensate. If you experience redness, itching, or discomfort, discontinue use and consult a dermatologist.

  • Massage your scalp with your fingertips (not nails!) for a few minutes to stimulate blood flow.
  • Avoid over-exfoliating, as excessive scrubbing can strip natural oils and lead to irritation.

5. Wash Your Hair According to Your Lifestyle

How often should you wash your hair? 

The answer isn’t one-size-fits-all—it depends on your environment, lifestyle, and personal hair needs.

  • For city dwellers: If you live in an urban setting, your scalp is exposed to pollution, dust, and sweat buildup. In this case, shampooing at least twice a week is essential to cleanse away impurities.
  • For minimalists and nature lovers: If you live in a clean, natural environment with minimal pollution, rinsing with plain water may be enough to maintain scalp health.
  • After workouts: If you sweat heavily, rinse your scalp with water post-workout to prevent salt buildup and irritation.

The key is to listen to your scalp. If it feels greasy, itchy, or flaky, it’s a sign that it needs cleansing. If it feels dry and tight, you might be overwashing.
