The Importance of pH in Cosmetics

When it comes to choosing the right products for your skin or hair, we often focus on ingredients, oils, vitamins, or botanical extracts. But there’s something many people overlook, and it quietly determines whether a product truly works: its pH level. Yes, that tiny number you might ignore on a shampoo or cleanser label plays a big role in how your skin and hair feel after every use.

What exactly is pH?

Think of pH as the mood of your product. It tells you whether it’s acidic, neutral, or alkaline, and this directly affects how your scalp and strands respond.

The pH scale runs from 0 to 14:

• 7 is neutral (like water)
• Below 7 is acidic
• Above 7 is alkaline
  

Your scalp naturally sits in the slightly acidic range  around 4.5 to 5.5. That’s its comfort zone, where it stays hydrated, calm, and protected.

Why pH Balance Really Matters

When you use products that don’t align with your natural pH, your scalp can get irritated. A shampoo that’s too alkaline can strip away moisture, causing dryness, flakes, or frizz, while something overly acidic can lead to sensitivity.

But when your products are pH-balanced, everything feels right, your scalp remains comfortable, and your hair stays soft, shiny, and manageable.

How to Tell If a Product Has a High pH

You don’t need a lab test to sense when a product’s pH is off  your hair and scalp will usually tell you. Here are some signs that a product may have a high (alkaline) pH:

1. Your hair feels rough or squeaky clean after washing. That “stripped” or overly clean feeling means the product has lifted your hair cuticle too much, taking away its natural oils.
   
2. Increased dryness or frizz after shampooing. A high-pH shampoo can leave your strands puffy, dull, or tangled, a clear sign the cuticle is too open.
   
3. Your scalp feels tight, itchy, or flaky. When your scalp’s natural barrier is disrupted, it struggles to hold moisture, leading to irritation and flakes.
   
4. Your color fades quickly (if your hair is dyed). Alkaline products can strip away pigment and reduce the lifespan of your color treatments.
   

If you notice any of these, it’s time to switch to pH-balanced formulas like the Adán Idét Hydrating Shampoo, Moisturizing Deep Conditioner, and Softening Leave-In Conditioner, which cleanse, hydrate, and protect without throwing your scalp off balance.

Where Adán Idét Products Fall on the pH Scale

At Adán Idét, every formulation is crafted to work in harmony with your scalp’s natural pH range  not against it. Each product is carefully balanced to cleanse, hydrate, and protect without disrupting your scalp’s comfort zone:

• Scalp Care Shampoo — pH 4.5: Designed for deep yet gentle cleansing, it purifies and refreshes while maintaining your scalp’s natural acidity. Perfect for those dealing with buildup or dandruff. Not suitable for daily use.
  
• Hydrating Shampoo  pH 5.5: A mild, moisture-rich cleanser that keeps your strands hydrated and your scalp balanced after every wash.suitable for daily use.
  
• Conditioners (Moisturizing Deep & Restorative Protein)  pH 5.5: Both conditioners smooth and seal the hair cuticle, locking in hydration, strength, and shine  leaving your hair soft, resilient, and beautifully balanced.
  

These pH values ensure that every Adán Idét wash day protects your scalp’s barrier, reduces dryness, and promotes long-term hair health. Because we don’t just care about what’s inside our products  we care about how they work with you.

 How pH Affects Your Hair

Your hair cuticle, that outer layer that controls shine and smoothness, reacts instantly to pH changes.

• Alkaline products (like harsh shampoos or relaxers) open the cuticle, causing roughness, dryness, and breakage.
  
• Acidic products (like conditioners and sprays) help close the cuticle, sealing in hydration and shine.
  

That’s why pH-balanced formulas are at the heart of Adán Idét’s creations.

Our Hydrating Shampoo, Moisturizing Deep Conditioner, Softening Leave-In Conditioner, and Hydrate & Refresh Hair Spray are carefully crafted to work in harmony with your scalp’s natural pH  hydrating, strengthening, and protecting without disruption.

The Benefits of Using pH-Balanced Haircare

1. Maintains a healthy, comfortable scalp
   
2. Prevents dryness, flakes, and irritation
   
3. Improves product absorption and overall effectiveness
   
4. Promotes stronger, shinier, more resilient hair
   
5. Keeps your scalp’s natural protective barrier intact

The Final Note

Your scalp has a rhythm, a delicate balance  and pH is what keeps it in tune. When you choose products that respect that balance, your hair grows stronger, your scalp feels calmer, and your natural beauty shines effortlessly.

So next time you pick a product, remember: it’s not just what’s inside, it’s how balanced it is. Because when your pH is right, everything else just falls beautifully into place.
