Alabama Barber Practice Exam

Semi-permanent hair coloring agents are designed to gradually fade out over time, typically lasting between 4-6 weeks. This makes option B incorrect as semi-permanent hair color will not last until the next shampoo. Option C is also incorrect as the lifespan of semi-permanent hair color is much shorter than 4-6 months. Option D is incorrect as semi-permanent hair color tends to last longer than just 1-2 weeks. Overall, option A is the most accurate as it aligns with the average duration of semi-permanent hair color.
