To get rid of a head cold try sipping warm drinks such as warm tea with honey, add moisture to the air with a vaporizer or humidifier, get plenty of rest and stay well hydrated.
You can use honey as a natural cough medicine that can help to relieve the symptoms of a head cold.
Another thing that helps with a head cold is to place a warm compress on your nose and forehead.
A warm wet washcloth works just as well placed over your nose and forehead several times per day to get rid of a head cold.
Other than that there's not too much you can do but wait and let the head cold or other cold run it's course and within a week or 10 days you should be feeling better and the head cold should be gone.
