How hair grows

Follicles cycle through growth, transition and rest. Visible length and fullness change gradually, so a few good wash days cannot establish new growth.

Who this is for: Anyone trying to make sense of regrowth claims or the timing of shedding.

Understand the concern

The follicle produces the strand below the skin; the visible shaft is not living skin. Anagen is the growing phase, catagen the transition and telogen the resting phase. Follicles are not all at the same point in their cycles. Shedding does not automatically mean a follicle has been permanently lost.

Practical steps

  1. Separate your goal into retained length, cosmetic fullness or new growth: they are different outcomes.
  2. Use monthly photographs with the same lighting and parting if monitoring a genuine change.
  3. Record illness, medicines and major changes alongside the timeline; a clinician can decide what is relevant.

Expectations and common mistakes

A surface-smoothing product can change appearance immediately. That is not evidence that it changed the follicle. Avoid measuring growth every day or treating every short hair as proof of a serum working.
