Oklahoma Barber Practice Exam

Instant conditioners typically have a low pH level which ranges from 2 to 4. This is lower than the pH of water (7), skin (around 5.5), and nails (around 7.5). The acidic pH of instant conditioners helps to close the cuticle of the hair, making it smoother and shinier. Using an instant conditioner with a higher pH level can lead to a rough, dull, and frizzy appearance. Therefore, the answer "A Hair" is the only option that accurately reflects the lower pH level of instant conditioners.
