How important is the right pH value for your hair – and why your hair care can do more harm than good

Have you ever wondered why some shampoos leave your hair feeling rough, frizzy, or unbalanced—even though they're said to be "gentle"? The answer could be as simple as pH.

At Dalarnas EKO we often talk about balance – and that applies not least to the pH value of the hair and scalp. It may sound technical, but it is crucial for maintaining healthy, strong and healthy hair.

What is pH value – and why does it matter?

The pH scale goes from 0 to 14, where:

• 7 is neutral

• Below 7 is acidic

• Above 7 is alkaline
  
  
  

The skin and scalp naturally have a slightly acidic pH, around 4.5–5.5 . This acidic environment is necessary for:

• Keep the surface of the hair shaft smooth and closed

• Maintain a strong skin barrier

• Protect against bacteria and fungi

• Maintain hair's moisture balance
  
  

What happens when the pH value is disturbed?

Many common shampoos and styling products have a pH value that is too high , often between 7–10. This can:

❌ Open up the surface of the hair shaft – making it more vulnerable
❌ Dry out the scalp
❌ Irritating sensitive skin
❌ Makes hair frizzy and unmanageable

How does Dalarna EKO work with pH?

We develop our shampoo bars together with hairdressers and chemists – always taking the pH value into account. Our shampoos & conditioners always have an optimal pH value between 4.5-5.5.

Each cake is balanced to mimic the skin's natural environment, making them:

🌿 Gentle on the scalp
🌿 Effective without drying out
🌿 Also perfect for sensitive, reactive or problem skin

We never compromise – not with pH and not with the quality of the ingredients.

How to tell if the pH is correct

✅ Hair feels soft and shiny – not rough
✅ Scalp feels calm and free from itching
✅ Hair becomes easy to detangle without weighing down products
✅ You avoid excessive oil production or dryness

A harmonious pH – the foundation for strong hair

Choosing hair care with the right pH is like giving your hair the environment it thrives in. It’s not just a detail – it’s the foundation for every other ingredient to do its job . Without the right pH, your hair has a harder time absorbing moisture, nutrition and care.

All of our products are carefully balanced to support the hair's natural state, without disrupting the delicate pH balance.
