How Can Body Hair Be Grown?

Hi.....This is Syed Muhammad Kamil, 24 years old male. I am having problems with my hairs. I don't have any body hairs not a single hair. I got typhoid when I was 8 years old and this fever lasted for 1 year. I sometime thinks that this might be one of the reason for losing hairs. I would be highly obliged if you can help me sort out this problem. Eagerly looking forward to hear from you soon. Thanks
