Sure, you’ve heard of the term ‘pH-balanced’ but do you really understand it? Here we explain what pH-balanced shampoo and skin care is and explore the benefits having a healthy pH-balance can have for your skin and hair.


The pH scale is used to get an understanding of how acidic or alkaline something is. If a product is pH balanced it means that it has the same pH as the thing it is intended to be used on. For example, human skin and hair is usually slightly acidic and has a pH of around 4.5-5.5. That means that if your shampoo or skin care claims to be pH balanced, it will likely have a similar pH level.


Healthy hair will be pH-balanced but if your hair feels week, dry or damaged or your scalp is prone to irritation, it is likely that the skin’s defence layer (the acid mantle) has been disturbed and is unable to perform its functions adequately.

There are lots of factors that can cause this to happen and the following can all affect the performance of the acid mantle:

  • Using alkaline hair products
  • Hair dye
  • Heat treatments
  • Exposure to chlorine
  • Exposure to sunlight


Human hair is protected by a thin, sticky fluid called the acid mantle. This acidic layer creates a hostile environment for alkaline bacteria and helps to keep the hair and scalp healthy.

Using harsh hair care such as shampoo bars and styling can weaken this defensive layer and may contribute to issues such as dry frizzy hair, an itchy, sensitive scalp or scalp acne. A weakened acid mantle may also leave the skin on the scalp vulnerable to microbial attack and could contribute to the emergence of scalp conditions such as seborrheic dermatitis.

By using a pH-balanced shampoo and conditioner you can maintain a strong skin barrier on your scalp and support the health of your hair as it grows.

All Green People’s shampoos are pH balanced and, because they contain nourishing plant actives in place of skin-stripping alcohols and SLS, they help to care for the delicate acid mantle and do not irritate sensitive scalps.


Much like our scalp, the skin on the rest of our body has an acid mantle which can be disturbed by using harsh, alkaline skin care ingredients. For this reason, all Green People’s skin care products have a pH between pH4.5 and pH5.5 and contain ingredients that nourish the skin while inhibiting the activity of bad bacteria.



Do you use a toner to help close your pores and reinstate your pH balance after cleansing? Whilst your toner might claim to help balance your pH, the reality is pores do not have muscles so will not close on their own regardless of how much toner you apply.

A better option is to opt for a pH-balanced cleanser that is rich in plant actives and rebalances the skin as you cleanse.

Armpits create the perfect environment for harmful bacteria so using a pH-balanced deodorant is also important.

To help your underarms defend themselves from bacterial invasion we pack our deodorants with a prebiotic called Alpha-Glucan Oligosaccharide. When applied to the skin, this encourages the growth of good bacteria and restricts the growth of bacteria known to cause BO.


Like shampoos, SLS-based soaps and shower gels can disturb the acid mantle and leave the skin feeling dry, sensitive or spot-prone. To avoid this, opt for a pH-balanced body wash that does not contain SLS.

Our Quinoa & Calendula Shower Gel contains extracts of Quinoa (which is mildly acidic) and combines this with strongly alkaline ingredient like Lemon Peel and SCS, derived from coconut, to create a natural pH-balanced shower gel that is kind to your skin.


Having dry skin on your hands can be a sign that your pH is too high or too low. Highly acid soap bars can further imbalance the skin but by switching to an SLS-free soap and applying a nourishing hand cream regularly, you can help to bring your hands back into balance.

Our pH-balanced Manuka & Lemon Tea Tree Antibacterial Hand Wash is free from SLS and irritating soap and contains Tea Tree & Manuka which deliver antimicrobial action against harmful bacteria.

To help preserve the acid mantle we pack our Manuka & Lemon Tea Tree Hand Cream with Sunflower oil. This contains a high level of linoleic acid which works to reinforce the skin barrier and reduce moisture loss from the surface of the skin. Naturally antibacterial, this skin-supporting hand cream also contains Lemon Tea Tree oil whch supports the natural healing of dry, chapped hands.
