Restoring the pH of the scalp may help prevent hair loss from dandruff, bacteria or fungus. Every liquid substance on Earth has a pH, or an acid-base, measurement. Very few substances are neutral; most are either acidic, such as vinegar, or basic, such as bleach.
Other factors which may change the pH levels in bodies of water are associated with organic material present in the water and plant growth. Decomposed material releases carbon dioxide, which in turn lowers the pH levels in the water.Learn more about Acids & Bases.
