I Want to Get Unstressed to Stop the Stress Hair Loss!

Hi,
Recently (past year) I have noticed that my hair is thinning all over the top of my head, even on the sdies too (less noticable, because of angle to lights). I have been rather stressed recently (working long hours at wierd times), and have also had a knee reconstruction. The hair that remains on the top my head is still fairly dense, and shows no sign of miniturization (colour loss or weakness). Assuming my hair is falling out due to stress, how long do I have to become unstressed before this hair is permanently lost?

If I am going bald, assuming I have 90cm square of bald patch, how many grafts will i need to get to totally cover my scalp when i want my hair about 1-2cms long (dry).?

Also, what would be the theoretical maximum amount of grafts i could put per centimetre of scalp?

If you are a woman and stress is the cause of the hair loss, it may reverse after the hair has gone through a telogen cycle (6-8 months). The surgery you had certainly adds stress. If you are a man, you should not be experiencing hair loss around the back and sides unless you have some disease going on like Diffuse Unpatterned Alopecia (DUPA).

With regard to estimating the need for grafts, all I can say is that the ‘art’ is not mathematical. But if you want numbers, the normal hair density is 1250 hairs per square inch. Generally (depending upon your hair color, characteristics and thickness of the hair shaft) you need less than half of that number to get back a normal ‘appearing’ density (625 hairs per square inch or about 300 follicular units per square inch assuming that your density is normal). People with low contrast hair to skin color (blonde on blonde) get away with less hair to ‘look’ normal, but people with high contrast hair to skin color (black hair on white skin) need to get closer to half of the original density. The maximum number of grafts into an area of the scalp in a single session, could run as high as half of the original density and some doctors claim that they do this, but that is rarely practical or needed in most people and all of the grafts packed together like that rarely grow.
