What role does pH play in hair care products?

It determines the fragrance of the product

It affects the price of the products

It affects the condition of the hair and scalp

pH plays a significant role in hair care products because it directly influences the condition of both hair and scalp. The hair and scalp have a natural pH, typically around 4.5 to 5.5, which maintains the health of the hair cuticles and the balance of scalp oils. When the pH of hair care products is too high or too low, it can disturb this natural balance, leading to issues such as dryness, frizz, or even irritation of the scalp. Products formulated with a pH level that is consistent with the hair and scalp help to keep the cuticle closed and healthy, which in turn minimizes damage and improves overall hair appearance and manageability. This understanding is essential for selecting and recommending appropriate hair care products for clients.
