Man Unaware of Shock Loss After Transplant

I am 37 years old male and I had hair transplant with 800 grafts four years ago. after hair transplant i lost my original hair which i had before transplant and now i left with only the hair which i transplanted. i have two question. first, is it normal for everybody that once you did hairtransplant you will lose your original hairs due to shock that our scalp get. my other question is regarding after transplant. since last year after getting shower the next day when i touch my scalp i notice the dead hair bulb ( i think it is called hair bulb or hair follicule, the material which hair grows from it ). it scared me alot. i have oily skin and when i touch my scalp i notice them it is like more then 10 per day. would you please give me some idea that why i lose my hair bulb besides my hair. and what should i do to prevent it.
thank you

Shock loss after a hair transplant occurs in some patients and it is best prevented by taking Propecia (which I prescribe to everyone having a hair transplant just to minimize this possibility). It is probably related to the degree of miniaturized or weak hairs that were in active loss phase when you had your transplant.

Regarding your second question of a ‘dead hair bulb’, I do not know what you are describing. It is normal to lose up to 100 hairs a day. What you are probably seeing is a hair shaft with a little sebum (mucus) plug attached at the end.
