Hair loss

Also see outer skin and gray hair.

Sensitivity follows the outer skin pattern.

Whether it involves the left or right side of the head depends on the biological laterality of the person.

Theme

Missing caresses, missing the "stroke on the head."
Or not being able to caress someone else, such as a grandchild or a pet.

CA phase

Continued hair loss on (part of) the head, numbness (reduction in sensitivity of the scalp) and temporary short-term memory loss.

Biological purpose

The numbness and amnesia cause the person being missed to be forgotten for the time being. One can therefore move on with life.
In animals, this also provides the solution.

Symptoms

Bald spots or a completely bald head. Dry, poorly perfused skin, formation of flakes or dandruff.

PCL phase

Hair loss stops and hair grows back.

Symptoms

Swelling, redness, pain, itching of bald spot, no new flake buildup.
Symptoms worse with the syndrome.
