Common Hair Problems

• According to the National Library of Medicine, common hair problems include hair loss, dandruff and folliculitis. The Mayo Clinic defines folliculitis as a hair follicle infection for which antibiotic treatment may be required. Dandruff is treated with either zinc or tar-based shampoos. Alopecia--hair loss--results from the body's immune system stopping the growth of new hair. The reason for this is not known, and as of August 2010, Minoxidil 2 percent, is the only treatment approved by the Food and Drug Administration for this condition.
  
  

Less Common Disorders

• According to Harvard Medical School, Poliosis is an uncommon disorder resulting in patches of white hair due to lack of pigment in that particular area. This condition is not reversible, however, some individuals choose to dye the affected hair to match their natural color. Atrichia is an extremely rare form of hair loss, which affects scalp hair, eyelashes, and eyebrows. As of August 2010, there is no known treatment for this condition.
  
  

Considerations

• Most cosmetologists or hairdressers are able to recommend specific shampoos to treat very simple hair problems such as dry or oily hair. For more complicated hair problems, a medical professional should be consulted. As of August 2010, ongoing clinical trials involving the study of hair disorders and diseases are being conducted by the National Institutes of Health.
