Comparison between plucked hair with good and bad roots. (a) Plucked hair with outer root sheath in the anagen growth phase transferred to a Matrigel coated culture flask. Keratinocytes grow out after 3–7 days. (b) Plucked hair without outer sheath root in katagen growth phase. No keratinocytes will grow out.
