The science of pH is an interesting and helpful measurement to understand for beauty and skincare. The range of pH is from 0-14, the lower the number the more acidic the pH is, with 7 being neutral. The higher the number above 7 indicates the level of alkalinity.
Our skin’s pH is usually between 4.5-5.5, which is slightly acidic. This helps our skin fight off surface bacteria. Our scalp has a pH usually between 4-7. The common problem with homemade shampoos is that the pH tends to be extremely alkaline due to the soap (usually Castile soap), with levels around 10-11. This alkalinity can soften the hair, but it also shocks the scalp, and it can take days for the scalp to recover to its normal pH level.
If you’re washing your hair daily, you might want to start slowing down on the frequency and start training your hair. Shampooing too frequently can strip the healthy oils from your hair and scalp. Start by washing your hair every other day (dry shampoo can really help!), and then ideally stretch it to every third day, which is optimal for both hair and scalp health.
pH Balanced Shampoo
This recipe for a pH balancing shampoo should be slowly integrated into your hair washing routine. You can start by using it once a week, and then eventually incorporate it into use every time you wash your hair.
pH Levels of Ingredients
Raw honey: pH of 4-5
Raw honey has antibacterial properties and is nourishing and gentle.
Sweet almond oil: pH of 4.5-5.0
Sweet almond oil is great for breaking down dead skin cells at the base of the scalp and is rich in vitamin E, potassium and magnesium.
Coconut milk: pH of 6.0-7.0
Coconut milk nourishes the hair while detangling and conditioning.
Just remember that this shampoo will not lather because it does not contain soap. But it will balance the scalp, remove dead skin cells, and nourish your hair. Use your fingertips to massage the shampoo into the hair and scalp to gently cleanse and break up dirt and product buildup.
