We see that ladies normally pluck the unwanted hair out. But they always grow back.
If you look closely you may be able to identify roots of these plucked hairs. Still somehow they grow back.
The reason is that the cortex of the hair stays inside and generates a new hair.
If the removed hair is planted back and some chemicals are used which promote growth, a new hair can emerge from the hair less region. This new hair will not be as healthy but it will be a hair.
This is known as Auto cloning which is still experimental but can be used at times.
After describing to the patient this experimental procedure can be performed as we see there is no harm in it. No loss to the donor site at all. And you can gain some additional hair that may mean a lot to the patient.
