If hair loss is caused by another illness, treatment of the illness is the best treatment for hair loss. If hair loss is the only problem, then there are many ways to treat it depending on how severe the loss is.
The most important consideration to make when deciding the type of treatment is how much your hair loss bothers you.
Treatment options include grooming techniques, wigs and hairpieces, medications, and surgery.
Styling hair to cover the areas with the most hair loss is effective for mild cases. Washing and styling the hair will not cause further hair loss.
For more severe hair loss, wigs and hairpieces can provide good results if you are willing to try them. Either of these options can be used in combination with medications or surgery if the results of styling or the hairpiece alone are not satisfying.
