Best pH balanced shampoo

Is your shampoo basic? And no, not like it’s ordinary or needs extra frills, but is it literally basic in pH? We might be familiar with the essentials of pH. Simply put, it’s a scale used for measuring how acidic or basic things are. 

While we often hear about pH in cleaning products or skincare, we hardly hear about it in hair care. 

But if we care so much about it when it comes to things we clean with or put on our faces, it does make sense that figuring out whether or not your shampoo is acidic or basic could make a difference in how your hair looks and feels. 


What is the best pH for shampoo?

The short answer would be anything with a pH from 5 to 7. 

This would put it right around the middle of the pH scale, leaning towards the lower end.

Let’s do a quick science crash course to put this into perspective! The pH scale goes from 1 to 14. The higher the number, the more basic a product is. 

The middle of the scale — seven — is the sweet spot where pH is neutral, neither acidic nor basic. So, anything below 7 is acidic, and anything above it is basic. 

Seeing as the best pH for shampoos is from anything that hits a 5 to 7, you’ll see that our hair loves slightly more acidic products.

Come to think of it. We add acids to a lot of our shampoos like apple cider vinegar, vitamin C, etc. And while stronger acids can definitely hurt the scalp, we don’t see any shampoos that are more acidic than a lemon. So, we’re pretty much clear from harm on the lower end of the spectrum. 

However, bases are really where shampoos can do some damage. 

There are lots of basic shampoos out there. It wouldn’t be such a huge surprise because bases are perfect for cleaning and killing germs. Most of our soaps are basic and safe for use on human skin, but bases can also have their extremes. 

The biggest harm bases can cause is opening up the surface of the hair shaft, leaving it frizzy and unsightly. It can also create tiny charges on the surface of each strand, increasing the friction and causing cuticle damage and breakage. 


What is a pH-balancing shampoo?

Our scalps and hair shafts are naturally on the acidic side. This is the main reason why we’d want our shampoos to stay on that end of the pH scale as well. 

Most shampoos out there are basic. This is because one of our favorite parts of shampooing, a rich and luscious lather, is usually brought about by basic chemicals in our products. But now that we’re taking a lot more care of our hair, there are products that aim to balance out the pH on our hair to maintain its natural state and improve how our hair looks and feels. 

Best pH balanced shampoo and conditioner - Tree to Tub Balanced Moisturizing Duo

The usual culprit for heavy basicity in shampoo is the lather. So it wouldn’t be too much of a surprise if you’d have to sacrifice it when you transition into pH-balanced shampoo. But Tree to Tub has found the best natural loophole for it. 

It’s a little magic ingredient aptly called Soapberry. 

They specialize in a wide range of soapberry-based products that give not just a rich naturally occurring lather but also nourishment. Soapberry is naturally healing and cleansing. Plus at a pH of 5.5, it closes the hair shaft for smoother, shinier-looking hair. 

This is an all-around natural and wholesome product free from sulfates, parabens and silicones, which are no-nos for healthy hair. Without these products, it’s safe to say that this shampoo is perfect for any hair type. It can work on super straight hair and can also be the best pH balanced shampoo for curly hair. 

What’s even better is if you like knowing where your products come from, especially in a shampoo full of natural ingredients, this brand has got you covered. 

You can rest easy knowing all the soapberry and other natural extracts in this product are fair trade, environmentally friendly, and sustainably sourced. That’s just the cherry on top that makes this duo our top pick. 

Pros: 

  • Natural formula 
  • Nourishing ingredients 
  • Lathers like conventional shampoos 

Cons: 

  • Natural oil content might be too heavy on thin hair 

Best pH balanced shampoo for color-treated hair - GIOVANNI 50:50 Balanced Shampoo

Overly alkaline or basic shampoos are bad news for color-treated hair. Color treating hair already opens up the hair shafts, making it susceptible to damage. Basic shampoos do the same.

The Giovanni shampoo is a pH balanced shampoo made explicitly for colored and even over-processed hair. 

Aside from the reparative properties of a more acidic shampoo like this one, it also has its unique mix of vitamins and nutrients, nourishing hair that needs that treatment the most. 

Don’t worry about this not clarifying enough, either. Instead of using harmful alkaline chemicals to clean the scalp, this relies on botanicals like rosemary to reliably do the trick. 

It also has aloe vera and other extracts that help hydrate and moisturize the hair for an added shine and gloss. 

Pros: 

  • Vegan formula 
  • Sulfate-free
  • Does not strip color out of hair

Cons: 

  • Strong scent
