For how long should perm solution be rinsed from the hair to avoid scalp irritation and unwanted lightening of hair color?

2 mins
3 mins
4 mins
5 mins

The correct answer is: 5 mins

A perm solution should be rinsed from the hair for at least 5 minutes to avoid scalp irritation and unwanted lightening of hair color. Rinse time is important to ensure that all the chemical residue is removed from the hair. Options A, B, and C are incorrect as they do not provide enough time for the solution to be completely rinsed out. Leaving the solution on for too long can cause scalp irritation and damage to the hair. It can also lighten the hair color, especially for those with lighter hair. Therefore, 5 minutes is the recommended time to rinse out the perm solution to avoid any potential issues.
