Between buzzwords and unfounded claims, it can be hard to find natural personal care products that deliver on their promises. In recent years, the demand for pH-balanced body wash and hair products have risen dramatically, but can they actually improve hair and skin? Is it just another marketing gimmick? Do you even need pH-balancing body products?

What Does pH-Balanced Mean? 

The pH scale goes from 1 to 14, with pure, room temperature water being the most neutral solution (landing at 7.0 on the scale). Any solution with a pH below 7.0 is considered acidic, and any solution with a pH above 7.0 is alkaline (ie. non-acidic).

How pH Values Are Measured

A one-point jump equals a ten-fold change in either acidity or alkalinity. For example, milk has a pH of approximately 6 and is ten times more acidic than water. The pH of orange juice is around 3, meaning that it’s about 40 times more acidic than water. 

What Is the pH of Healthy Skin? 

A healthy skin pH is typically between 5.4 to 5.9, with some studies even indicated that healthy skin is often slightly more acidic (ie. below 5)1. Certain products with higher pH levels can cause dehydration, irritation, and alter bacterial flora.

Benefits of a pH-Balanced Body Wash

A healthy skin pH tends to land somewhere between 5.4 to 5.9. Soaps and body washes that have high pH ranges can wipe out hydration, irritate skin, and alter bacterial flora levels (which can lead to inflammation and breakouts). 

Quite simply, most soaps and body washes have a pH range of 9 to 10. That’s certainly not ideal for sensitive – or even normal – skin.

When you use a pH-balanced body wash correctly, your skin will be better able to maintain a normal, healthy pH range. With our team of PhD chemists and dermatologists, we developed Puracy Natural Body Wash to have a pH of 5.5. Our gentle, plant-based cleansers soothe and cleanse away dirt and other impurities.

What Is the pH of Healthy Hair? 

When it comes to products used on it, hair is sensitive to pH variation. Most human hair has a pH level of around 3.5-3.7. Meanwhile, the scalp's level is generally around 5.5 pH.2

Shampoo companies aren’t required to share pH values on their labels, but this same study revealed that only 38% of the nation’s most popular shampoos had pH levels that were less than 5.0. The vast majority were usually between 6.0 and 7.0. Even the pH of “no-tear” children’s shampoos averaged 7.0. 

It’s likely that alkaline hair products increase electrical charge (and therefore friction) of hair fibers, leading to damage of the hair shaft and cuticle. A more acidic shampoo generates far less static electricity and keeps hair more manageable.

Signs You Might Benefit from pH-Balanced Shampoo

If you have a sensitive scalp or hair that easily dries out, seek out shampoos from manufacturers that promote balanced pH levels. In addition to reducing frizz, static electricity, and dryness, pH-balanced shampoos (less than a 6.0 pH) will help to maintain a healthier scalp and reduce chances of flaking and dandruff. 

Puracy Natural Shampoo & Conditioner 

Puracy worked with our team of PhD chemists and hair care professions to create our Natural Shampoo. With approximately the same acidity as your skin (5.5), this formula reduces irritation, dryness, and itchiness.

If you’re using a more alkaline conditioner, the cuticles remain open, and you might experience drier, frizzier hair. That’s especially true if you style your hair with heat (ie. curling irons and hair dryers) or regularly use harsher treatments (ie. hair dye and perms). 

More acidic conditioning products – with a maximum pH of 5.5 – help hair cuticles maintain moisture while preventing damage. We developed our Natural Shampoo to be used in tandem with our pH-balanced conditioner, which is why it has an acidic pH of about 4.0. 

Pro Tip: For best results, use our Shampoo and Conditioner for at least 2-3 weeks.
