__ 22. Which statement describes ammonia? It is an alkaline agent that raises the pH of hair colorant and can change the hair's texture and curl pattern. b. It regulates the amount of lift in lightener products. b.It is an oxidizing agent that can be used alone to lighten the hair one level. d. It is a developer that has a pH range of pH1.5 to pH3.5

The correct answer is:<br /><br />a. It is an alkaline agent that raises the pH of hair colorant and can change the hair's texture and curl pattern.<br /><br />Ammonia is a common ingredient in hair color products. It acts as an alkaline agent, which helps to open up the hair cuticle and allows the color to penetrate the hair shaft more effectively. This can result in a more vibrant and long-lasting color. However, ammonia can also alter the hair's natural texture and curl pattern, which may not be desirable for all hair types or styles.
