My boyfriend is 20yrs old and his hair line is going further back like going bald why ? i'm also losing hair a lot it's thinning. help

Many reasons: Your boyfriend may be developing male-pattern baldness, which develops in many men. While it is inherited, no one knows whether this is inherited from the mother or father. An oral medication, which is a prescription can be taken for this, however, you must continue to take it or the hair will fall out. You could have different reasons for hair loss-hormonal problems, low ferritins, thyroid levels
