Scalp Had No Sensitivity After Brain Surgery

Hello Doctor,

Im male 30yrs. I had a brain surgery 3 yrs ago. After surgery, I had no sensitivity in mid or top of head. The hairs on that part started shading/ thinning slowly and then turned like baldness. Now Im getting sensitivity in that parts of head. Can I expect the hairs i lost or thinning be converted into thickness or hair growth? Can you pls advice me on how can I grow the hairs back/thickness on my crown/central head part?

Thanx in advance

I am not sure that I can help you evaluate your problem without examining you. The brain surgery may have cut critical sensory nerves in the scalp to cause your numbness. If the temporal vessels and nerve was cut on just one side, then you might have a sensory defect to cover the top and the side of your scalp. If both were cut, then you would have complete numbness, some of which could reduce over time as other nerves from the back of your head may take over. Any vascular damage could produce hair loss as well. Either your brain surgeon could/should tell you why you have this problem or any good doctor examining you will know what to look for. I would be happy to evaluate you if you are in or near California and would like to pay me a visit.
