Donor area too thin after HT. Is this normal or not?

Dear houssam23,Thank you for writing in with your question. Overharvesting of the donor area is common with providers that are new to the specialty of hair restoration. One cause is simply taking too much hair. Another cause is a telogen effluvium (eg: shock loss) that can occur in the donor area is great care is not take to prevent this phenomenon in larger cases such as ones over 3,000 grafts. If your hair shaft diameters are small (eg: you have fine hair, in which the actual hairs are fine all over your head) you are predisposed to have a greater amount of scalp showing in the donor area than a person with thick hair shaft diameters. There is hope, however, because if this was caused by a simple shock loss situation, it will most likely improve over the next 4-5 months as the hairs that were knocked out of their growing phase by the procedure return. I hope this information is helpful to you.

it is too early to say something about the donor area. it can be a shock loss and you should wait until it gets held totally and consult with your doctor

If you take out 3650 out from your donor area, then you will be missing 3650 grafts from the donor area.  Of course it may look thinner based on how you keep your hair cut.  If your hair is very long in the donor area, it would not likely show the thinning.  If your hair is very short, it will likely look thin (especially with the FUE procedure).
