Which of the following is NOT a phase of nail growth?

The phases of nail growth typically include a growth phase, resting phase, and shedding phase, reflecting the biological processes involved in nail formation and lifecycle. The growth phase is when new nail cells are produced, leading to lengthening of the nail. Following this is the resting phase, during which nail growth slows, and eventually, the nail sheds as new cells continue to form underneath.

The option referring to a maturing phase is not recognized as a distinct phase of nail growth in standard nail growth cycles. While nails do undergo changes during their growth and after shedding, these are considered part of the growth and resting phases rather than a separate "maturing phase." Therefore, identifying the maturing phase as not part of the established cycle highlights the understanding of nail biology correctly.
