An alkaline product is characterized by having a pH above 7. This higher pH level indicates that the product is capable of neutralizing acids and may be used to perform specific functions such as opening the hair cuticle or achieving certain chemical treatments in cosmetology. Understanding the pH scale is crucial for professionals in the field, as it guides them in selecting appropriate products for various hair and skin treatments, ultimately ensuring they achieve the desired results without causing damage. Other characteristics such as being colorless or odorless do not define alkalinity and are unrelated to the actual pH measurement of the product.
