A client has coarse, resistant hair and wants a tight curl from a permanent wave. Which rod and timing strategy fits best?
a.Smaller rods, longer processing time
b.Larger rods, longer processing time
c.Smaller rods, very short processing time
d.Larger rods, shorter processing time
Explanation
Tighter curl comes from SMALLER rods. Coarse, resistant hair is harder for chemicals to penetrate, so it usually needs LONGER processing time. The combination smaller rod + longer time gives a tight curl on resistant hair. Always follow the manufacturer's directions and confirm with a test curl.
