Hair loss occurs naturally at a rate of about 100 hairs a day. Various factors—including diet, stress, hormone levels and genetics—can accelerate hair loss beyond this rate, creating noticeable patchiness throughout the scalp. In some cases, hair loss may not be preventable, or reversible, but in other situations, the proper precautions can ensure adequate, continuous hair growth.
Healthy Nutrition
Because hair growth and development requires iron and protein as well as vitamins like the B-complex vitamins for mineral synthesis, a diet deficient in these nutrients can result in hair loss, according to research provided by the University of Maryland Medical Center. Most normal eating styles provide enough nutrients to meet the demands of growing hair, but strict vegan diets and low-calorie diets may not provide enough resources for hair development. Therefore, if you feel that you do not receive a sufficient diet of iron, protein or the B-complex vitamins, then take a supplement. Any normal once-a-day vitamin supplement containing those nutrients will suffice.
Relaxation
One of the leading causes of hair loss in women is stress. According to the American Academy of Dermatology (AAD), telogen effluvium involves the premature entry into the resting stage of hair development due to hormonal imbalances and other stress-related issues, such as pregnancy, rapid weight loss, emotional shock, trauma or severe fever. To prevent hair loss due to stress, engage in regular stress-reduction exercises. For example, deep breathing techniques, where you inhale deeply through your nose and exhale from your mouth, can help lower your heart rate and reduce anxiety. Also, the University of Maryland Medical Center recommends yoga, prayer and meditation as other methods to stay calm and collected.
Good Hair Care
The AAD suggests that you take proper care of your hair to prevent damage and hair loss due to constant pulling or chemical treatment. For instance, gently dry your hair after exiting the shower. The AAD says hair becomes more vulnerable when wet and may fall out during harsh drying procedures. Likewise, allow your hair time to dry before combing or brushing it. Also, avoid repeatedly using hair chemicals, such as relaxers or dyes, and avoid overly using the blow dryer as it can damage the hair follicle. Finally, apply conditioner following shampooing to restore the oily protection needed to keep hair strong, shiny and protected against the elements.
Medication
In the event that you experience hair loss due to genetic factors, the FDA-approved drugs minoxidil and finasteride can help prevent excess hair loss due to androgenetic alopecia. According to Dr. Philip Ginsberg, as reported by the American Osteopathic Association, minoxidil works in more than 20 percent of cases and finasteride has a 50 percent or better success rate. For the best results, start treatment early at the onset of hair loss.
