anyone had real bad shock loss?

I had pretty bad shock in my donor area after my first FUE session with Jones but i think this has been the worse case or reported one anyway. There are some pics floating about best run a search. The hair all grew back after 5/6 months

Generally, Shockloss is something that can be experienced when transplanting into existing hair although highly unpredictable. Shockloss occurs when the native hair is weak and isn't strong enough to resist the trauma thats going on around it. More often than not the hair that has gone into shock will grow back but after 3/4 months - after the resting phase
Hair that goes into shock and doesn't return is hair that was inevitably on its way out anyway and wasn't strong enough to return.
Increased trauma to a localised area will increase the chances of shockloss.
Shockloss is unpredictable and there is no hard and fast rule to avoiding it - especially if you are transplanting into existing hair.
There are risk factors that either heighten or lessen someone's risk. Diffuse thinners seem more prone to shockloss than receders because the hair in a diffuse area is often less stable than that of a receder. Very often, a lot of the hair in a diffuse area is "on its last legs" and in the latter stages of the miniaturization process.

Spex makes a great point.........shock loss is very unpredictable.

I've experienced it both in the recipient area and along the donor area. HT #1 I had quite a bit of shock loss in recipient and donor areas. I don't believe all the shocked hair in the recipient site came back. Most of the hair around the donor area did but one place on the left side was worse than the rest. I also had some shock loss during HT #2 but the majority of it came back.

This is speculative but I do believe another large contributing factor to shock loss is determined by the skill set of the surgeon performing the HT.

Good points

I think it also had to do with the amount of grafts you receive in an area. The more Trauma to the area the more likely to have shockloss ( of course everyone is different but it is common sense). I just had my thrid procedure and had some excess shock loss on one side of the donor area..No probem because I can cover it up with dermatch.. Keep in mind if you are going for one fo these MEGASESSIONS you will most likely have to shave your head so it doesn't matter anyway. I took the more conservative route at 1417, 1476, and 2124

good luck
