5 Facts On Ph Of Hair : Types, Factors And Reasons

What is the pH of Hair?

The pH of hair ranges between 4.5 and 5.5. This is slightly acidic, which helps to maintain the health and integrity of the hair.

Why is the pH of the Hair significant?

The pH of hair is significant because it affects the appearance and health of the hair. When the pH is balanced, the hair cuticle is smooth and closed, which helps to prevent damage, breakage, and frizz. A balanced pH also helps in maintaining the natural oils of the hair, thereby keeping it healthy and moisturised.

How can we maintain the pH of the Hairs?

The pH of hairs can be maintained by following the given steps.

  1. Use pH-Balanced Hair Products: Use hair products that have a pH level similar to that of your hair. It helps in maintaining the natural pH balance of hairs. Avoid products that are too acidic or alkaline as they can disrupt the pH balance of your hair.
  2. Avoid Overwashing: Washing hairs frequently can strip off natural oils and affect the pH balance of the hairs. 
  3. Rinse with Cool Water: Using hot water while washing your hair can open the hair cuticle, which can disrupt the pH balance of hairs. Rinsing hairs with cold water helps in sealing the cuticle and maintaining the pH balance of the hairs.
  4. Use Natural Hair Products: Natural hair products are generally balanced and free from toxic chemicals. It helps in maintaining the natural pH balance of the hair.
  5. Use Apple Cider Vinegar: Apple cider vinegar (ACV) can help in restoring the pH balance of the hair. Mix it with water and use it as a final rinse after shampooing.

Factors affecting the pH of Hair

There are multiple factors that alter the pH of hair, including

  1. Hair Products: Hair products such as shampoos, conditioners, and styling products can affect the pH of hair
  2. Chemical Treatments: Chemical treatments like smoothening, keratin, colouring and perming can affect the pH of hair. These treatments can alter the natural pH balance of hair, causing it to become more alkaline or acidic.
  3. Water Quality: The quality of the water you use to wash your hair can affect the pH of your hair. Hard water, which contains high levels of minerals such as calcium and magnesium, can cause hair to become more alkaline.
  4. Environmental Factors: Environmental factors like exposure to sunlight, pollution and humidity can alter the pH of hair. Sunlight can open the cuticle, while humidity can make hair more alkaline. Pollution can also decrease the pH of hair.
  5. Health: The health of your hair can also affect its pH. Hair that is damaged or over-processed may have a higher pH, while healthy hair usually has a lower pH.
