How is a salt bond affected?

  1. Heat styling

  2. Sun exposure

  3. Affected by pH level

  4. Use of conditioner

The correct answer is: Affected by pH level

Salt bonds are formed between positively charged amino acids and negatively charged acids in the hair. The pH level refers to the acidity or alkalinity of the hair. When the hair's pH level is altered, the salt bonds become affected and can lead to changes in the hair's texture and strength. Heat styling and sun exposure can also affect the hair's pH level, but they do not directly impact the salt bonds. Similarly, the use of conditioner can help maintain a balanced pH level in the hair, but it does not directly affect the salt bonds either.
