Using one of the best pH-Balanced shampoos is essential for the overall health of your hair and scalp.

In fact, research has shown that a shampoo with an alkaline pH level may increase the negative electrical charge of the hair fiber surface, increasing friction between fibers and potentially causing cuticle damage and hair fiber breakage.

Whereas a shampoo with a pH level of 5.5 or lower (also known as pH-balanced) have the ability to reduce frizz, breakage, and friction between fibers, resulting in less damage overall, it also implies that the pH of the scalp is maintained at its normal level.

Studies have also found that 62% of consumer-brand shampoos had an alkaline pH, while only 25% of professional brands used in salons had an alkaline pH.

In this article, you’ll find all you need to know about pH-balanced shampoos, as well as a list of the best formulas for you to consider based on your hair type and needs.

The pH scale runs from 1, which indicates that a product is highly acidic, to 14, which signifies that a product is highly alkaline. To put things in perspective, water is totally neutral at a 7 on the pH scale.

Now you may wonder why the pH of your shampoo is so important for the health of your locks. Continue reading to learn more.

Why Should You Use a pH-balanced Shampoo?

Since the pH of the hair shaft is around 3.7 and the pH of the scalp is approximately 5.5, then it’s obvious that we need to use a shampoo with a pH that respects the hair’s natural acidity (5.5 or lower).

Furthermore, as previously indicated, alkaline shampoos cause the hair cuticles to open and lift off, resulting in frizziness, unmanageability, and tangles.

Shampoos with low pH can help:

  • Reduce frizz and flyaways.
  • Control static and improve manageability.
  • Promote a healthier scalp.
  • Minimize hair breakage and damage.
  • Make the hair smoother.


If you are having problems with your locks and you know that you need to work to get healthier strands, then finding a good acidic shampoo is likely your smartest move.
