Explanation:

Hair growth has phases. The resting stage (telogen phase) duration affects hair length. Longer resting stage means hair stays on scalp longer, influencing length. Age (A) affects growth rate but not directly length. Rate of growth (B) affects how fast it grows, not max length. Hair bulb size (D) relates to thickness. Hair root angle (E) relates to hair appearance (e.g., curly vs straight).
