There's a pH in the hair too…
Did you know that your hair holds a pH balance too, not just down there! Well, let me tell you all about it.
What Is the Ideal pH for Hair and Scalp?
The natural pH of the scalp and hair typically ranges between 4.5 and 5.5. You were thinking around a 7, huh? Nope, water has a natural pH of 7, which has been scientifically proven to be too strong for hair alone. That is why your hair becomes surprisingly dry once wet. This slightly acidic environment helps keep the cuticles of the hair shaft smooth and the scalp free from harmful bacteria and fungi.
Understanding the pH of Hair and Scalp: Why It Matters
Maintaining the right pH balance is crucial for healthy hair and scalp. Many people overlook this factor, yet it plays a significant role in hair strength, moisture retention, and overall scalp health. So, the products you use, you should be looking at those labels and reading to see what the balance of those products is to make sure it's helping your hair and scalp, not stripping it.
Effects of an Imbalanced pH
But what if my hair is “damaged?” Well, I’m glad you asked!
When the pH of your hair and scalp is too high (alkaline) or too low (overly acidic), it can cause several issues:
Dryness & Breakage – Alkaline conditions lift the hair cuticle, making it rough, brittle, and prone to damage.
Frizz & Unmanageability – Raised cuticles also allow moisture to escape, leading to excessive frizz and difficulty in styling.
Scalp Irritation & Dandruff – An overly alkaline scalp can become dry and flaky, while too much acidity may cause irritation or excess oil production.
Bacterial & Fungal Infections – The scalp’s natural acidity helps prevent harmful bacteria and fungi. If disrupted, it can lead to scalp conditions like dandruff or itchiness.
Product Buildup – When the pH is off, products may not absorb properly, leading to buildup that suffocates the scalp and weakens the hair.
Benefits of a Balanced pH
Believe it or not, it can be very challenging to find what works for you and your scalp to create and maintain healthy hair.
But truly, maintaining a healthy pH between 4.5 and 5.5 offers numerous benefits such as:
✅ Stronger, Shinier Hair – A balanced pH keeps the cuticle smooth and intact, resulting in hair that’s more resilient and glossy.
✅ Healthy Scalp Environment – It prevents excessive dryness or oiliness, reducing the risk of dandruff and irritation.
✅ Better Moisture Retention – Hair holds onto moisture more effectively, keeping it soft and hydrated.
✅ Improved Product Absorption – pH-balanced hair care allows products to work as intended, maximizing their benefits.
✅ Stronger Locs & Less Buildup – For those with locs, a balanced pH helps prevent residue accumulation and ensures long-lasting, healthy locs.
How to Maintain a Balanced pH
Now that you know the effects and benefits of both damaged and healthy locks, it’s time I inform you on how to maintain a healthy balanced head full of hair:
Use pH-balanced shampoos and conditioners to keep your hair and scalp in their natural state.
Rinse with diluted apple cider vinegar (a natural acidic remedy) to restore balance after using alkaline shampoos.
Avoid harsh, alkaline hair products that strip moisture and disrupt the scalp’s equilibrium.
Moisturize with natural oils like jojoba or argan oil, which closely match the scalp’s natural pH.
Keeping your hair and scalp pH balanced is the key to strong, healthy locs and overall hair wellness. If you're unsure whether your products support this balance, consult with a professional loctician (like me!) to create the best regimen for your hair type.
