What does pH stand for in relation to hair products?

The term pH stands for "Potential of Hydrogen." It is a scale used to determine the acidity or alkalinity of a substance, with a range typically from 0 to 14. In the context of hair products, understanding pH is crucial because it affects the health and appearance of hair. Hair products with a pH that is too high (alkaline) can lead to hair damage and cuticle lifting, while those that are too low (acidic) may weigh the hair down and affect its texture.

Hair tends to be healthiest at a slightly acidic pH of around 4.5 to 5.5. Products formulated within this pH range help maintain the natural balance of hair and scalp, ensuring that the hair cuticles lie flat and the hair remains smooth and manageable. Knowing the pH of hair products aids cosmetologists and clients in selecting appropriate products that promote healthy hair and scalp care.
