What causes fishhooks or uneven curls in a permanent wave?

• A. Incorrect winding or hair ends not properly wrapped
• B. Too much heat during processing
• C. Not washing the hair thoroughly
• D. Using the wrong formula

Answer: (A)

Fishhooks and uneven curls come from how the hair is wound around the perm rod. When the ends aren’t fully wrapped and kept aligned with the rod, they don’t respond the same way as the rest of the strand, so the ends bend or kink into hook shapes and the curl isn’t uniform along the length. The remedy is precise winding: wrap each section smoothly, keep the ends flat and tucked against the rod, and maintain even tension from ends to scalp so every part of the strand curls in sync. Other factors like excessive heat, residue from not washing, or using the wrong formula can cause other processing problems, but the specific issue of fishhooks points to wrapping technique.
