I detangle with a fine tooth comb once every few weeks. I otherwise use a wide tooth comb and oil or condition my fingertips and then run my fingers through my hair to pull out shed hairs.
Once I get around to detangling with a smaller tooth comb, I lose a LOT of hair. IMO, you should not change your regimen, becaause my guess is your hair is "balanced" and doing so will only mess up a good thing, with the exception of detangling more often if it really worries you.
My mothers hair was FALLING OUT for a time. Though I gather a LOT of hair in my comb once I finally detangle well (meaning beyond what I do in the shower with a wide tooth comb), there is a BIG difference in the amount of hair we shed.
I agree with the others who have said it is highly unlikely you are losing an abnormal amount of hair. You would "KNOW" (meaning, you would be in tears, not calm or rational, crying, freaking out, holding the hair in your palms, etc., or doing whatever version of SEVERELY freaking out that would be more appropriate for you, depending on the type of person your are). I am a very calm person, and I doubt that if I were using a seriously unnatural amount of hair, my hair's condition would still be good enough that I would not be a mess over it, or that I would be curious or questioning over frightened.
I think your hair is fine. Like I said, if it really bothers you, style in a way that requires more detangling, or you can continue what you've been doing and observe your hair more. That is how I figured out the effects of not combing as often and thoroughly on my hair.
I hope your hair remains healthy.
