Great question. Unfortunately there is not a clear cut answer here. We all lose hair at different rates. It is normal to see hair loss when combing, brushing and washing our hair. But what is normal and what is excessive will have to be something only you can determine. You mentioned that it looks like you have more hair falling out than normal. That would be a red flag. Now the reasons your hair is falling out faster can be hard to determine, as well. It could just simply be your age and genetics. Hair loss can also be caused by medication, medical issues, chemo and even stress. Not eating healthy can actually cause our hair to fall out as well.

Take a look at your life and see if you can rule some of these things out. If you know you have a clean bill of health, have not started new meds or changed your diet, perhaps you have been under a lot of stress lately.

Excessive hair loss can be genetic. If you notice a gradual increase in the hair loss or even a receding hair line, it could just be the cards you were dealt in life. Always feel free to talk with your doctor. Sometimes they can guide you in the right direction.
