I am a 16 year old male and I have always had thick hair, about 6 months ago I noticed that my hair has been significantly thinning on top and I've been shedding alot. My mothers dad had a full head of hair and my moms brothers started thinning during there early to mid 30's. Also I have a very poor eating habit and my younger brother (age 10) has hairs falling out alot and we both have little white bulbs at the end of each hair thst is shed
