What does a pH of 14 indicate?

A pH of 14 indicates a strong alkaline solution. The pH scale ranges from 0 to 14, with values below 7 being acidic, values above 7 being basic (or alkaline), and a value of 7 being neutral. When pH levels approach 14, it signifies the presence of highly alkaline substances, which have a strong ability to accept protons or donate hydroxide ions in aqueous solutions.

In the context of cosmetology, understanding pH is crucial, particularly when working with products that can affect the skin and hair. High pH values are often associated with cleaning and chemical processes that can significantly modify the structure of hair and skin.

Values such as 0-6 on the pH scale indicate varying degrees of acidity, while 7 reflects neutrality, neither acidic nor alkaline. Therefore, knowing that a pH of 14 corresponds to strong alkalinity helps in selecting the right products for particular treatments and understanding their potential effects on the hair and skin.
