Why does my hair have a little white bulb in the end?

lately, whenever I wash or detangle my hair, I get these pieces with a little white bulb in the end. what does this mean?

That means your hair has come out by the bulb.  This is typically not very visible for normal hair shed.  This could mean you are wearing styles that are too tight for your hair.  Be sure to begin treating your scalp as well as you treat your hair to make sure your hair does not start excessive shedding which would be anything more than 50-100 hairs day. 
It means those ends are split, you need a trim. Trim ends and dc your hair and you should be fine. Remember to keep those ends moisturized.
