pH balanced shampoo: What is it, and why does it matter?

Benefits of using a pH balanced shampoo

Using a pH balanced shampoo supports both hair and scalp health by maintaining the natural acidity needed for optimal function. Key benefits include:

• Helps preserve the scalp’s protective barrier, reducing irritation and environmental stress

• Slows colour fading and maintains vibrancy in colour-treated hair

• Reduces frizz and static, improving manageability

• Retains moisture within the hair shaft, enhancing softness and reducing breakage

• Regulates sebum production, balancing oiliness and dryness

• Creates a more stable foundation for healthy hair growth

This makes pH balanced shampoos suitable for a wide range of hair types and scalp conditions.

Who benefits the most from pH balanced shampoos

Although pH balanced shampoos are suitable for everyone, they are especially beneficial for individuals with specific hair and scalp needs. These include:

• Those with colour-treated or bleached hair, as it helps retain colour and reduce fading

• People with curly, textured or chemically treated hair, due to improved manageability and moisture balance

• Individuals with sensitive, dry or itchy scalps, who may experience less irritation and greater comfort

• Anyone aiming to maintain long-term scalp health without disrupting the hair’s natural structure

These shampoos offer targeted support while remaining gentle enough for regular use across hair types.

How to identify a good pH balanced shampoo

When selecting a pH balanced shampoo, consider the following criteria:

• Look for products that clearly state a pH between 4.0 and 5.5

• Choose formulations that are free from harsh sulfates, parabens, or drying alcohols

• Prefer shampoos that contain gentle cleansing agents and natural pH stabilisers, such as citric acid or lactic acid

• If the pH is not listed on the packaging, consider reaching out to the brand for clarification

These steps can help ensure that the shampoo supports the natural pH environment of your scalp and contributes to healthier hair over time.

Ingredients that support pH balance

pH balanced shampoos often contain specific ingredients that support a gentle and acidic environment. Some of the most effective ones include:

• Aloe vera, which soothes the scalp and provides moisture

• Panthenol, also known as provitamin B5, which strengthens the hair shaft and improves hydration

• Plant-based extracts, which offer antioxidant benefits and help maintain scalp balance

These naturally derived components are ideal for sensitive scalps and moisture-deprived hair. Together, they help maintain the integrity of the hair's cuticle layer while enhancing softness, manageability, and shine.

Shampoo spotlight: Repair and Care & Grow and Glow

Two of our most popular shampoos, Repair and Care Shampoo and Grow and Glow Shampoo, are formulated with ingredients that help maintain the natural balance of the scalp and hair.

Repair and Care Shampoo is ideal for dry, damaged or color-treated hair and contains ingredients like glycerin and betaine to help retain moisture and improve softness. It is free from sulfates and silicones, making it suitable for gentle cleansing without disrupting the scalp's natural barrier.

Grow and Glow Shampoo includes aloe vera and caffeine, which contribute to stimulating the scalp and strengthening the hair roots. This shampoo is also free from sulfates, silicones and drying alcohols, making it well-suited for regular use without causing dryness or imbalance.

Both shampoos are developed with mild and well-balanced formulations that support a healthy scalp environment and reflect our commitment to high ingredient quality.

Why pH-friendly formulation matters

Avoiding ingredients that significantly raise pH, such as strong soaps or alkaline surfactants, helps ensure the shampoo remains within the desired range and supports optimal hair condition. This approach contributes to a more stable moisture balance, reduces the risk of irritation, and reinforces the long-term resilience of hair fibres.

Application tips

To maximise the benefits of using a pH balanced shampoo, follow this step-by-step routine:

Start by thoroughly wetting your hair with lukewarm water. Avoid hot water, as it can strip natural oils and disrupt scalp balance.

Apply a small amount of pH balanced shampoo to your palms and distribute it evenly across your scalp.

Massage the shampoo gently using your fingertips to stimulate circulation and ensure effective cleansing without causing irritation.

Rinse your hair thoroughly, ensuring all product is washed out to prevent buildup.

Follow with a conditioner that complements your shampoo in pH and ingredient profile to maintain moisture and softness.

Gently towel-dry or air-dry your hair without excessive friction, which can damage the cuticle.

Over time, observe how your scalp and hair respond, and adjust your routine if needed—for instance, by alternating with other treatments or adjusting frequency based on your hair type.

Addressing misconceptions

Many people believe shampoos are naturally pH balanced, but that is often not true. Some shampoos contain harsh detergents, such as sulfates, that raise the pH level, which can harm the hair cuticle, cause dryness and scalp irritation, and fade colour. Even products marketed as 'natural' may not support the scalp’s acid mantle. 

To protect your hair and scalp, it is helpful to check the product’s pH level. Choosing pH balanced shampoos supports healthy hair and scalp over time.

Bringing balance to your routine

A pH balanced shampoo supports the integrity of both hair and scalp by aligning with their natural acidity. Choosing a product within the ideal pH range can improve moisture retention, reduce irritation, and enhance overall hair health. By understanding the importance of pH, you can make more informed decisions and support long-term hair care success.
