Depression, disease and medical conditions can accelerate hair loss

I had my third epidural in my lumber spine and within a few weeks big chunks of hair started falling out, 1 patch of hair about size of a plum. Some days it’s fine then others clumps still fall out. I now have gone totally bald and it’s really affecting my depression and anxiety. I was wondering if anyone knows if it will grow back and how long as it’s near front so can’t hide it.

You need to see a doctor about your hair loss to find out if it is caused by medical conditions such as a disease entity or if it is purely genetic hair loss which can be accelerated by stress. Once you know, if the diagnosis is genetic hair loss and assuming that you are male, the drug Finasteride can maybe stop it. If it is from another disease, then you need a diagnosis.  People who have conditions like you and who have stress from your primary problem (in your case your spinal problem) can cause the genes for hair loss to kick in and accelerate the hair loss that you may get in the years to come. Without pictures, it is impossible to know what you mean that you have gone totally bald so either send photos or see a doctor to make a diagnosis.
