Preventing hair loss can be possible through medical treatments and self-care as well as maintaining a healthy diet. Before recommending any treatment plan for you, your hair loss type and the causes must be identified. This can only be possible with the correct diagnosis made by a specialized doctor. Additionally, determining whether or not the hair loss condition is permanent or temporary and progressive or stable, will also be helpful for choosing the most effective treatment program for you.

With most hair loss cases, in either men or women, there is a genetic predisposition. Environmental factors can worsen or hasten the onset of thinning and shedding due to genes. Common issues include pregnancy, iron deficiencies, surgery, stress, medication side effects and hormonal changes. Through studies on identical twins, excessive sun exposure can also be detrimental to the effect of UV rays which create free radicals in the skin tissue. This can undermine the health of the hair follicles. Also, the use of extensions and tightly pulling hairstyles (e.g. buns, ponytails, dreadlocks) can contribute to traction alopecia, which can be a permanent form of hair loss if the follicles are permanently damaged.
