Beverly Hills Hair Transplant Clinic's Top 4 Reasons for Hair LossHome / / Beverly Hills Hair Transplant Clinic's Top 4 Reasons for Hair Loss
1. Hormonal abnormalities. A variety of hormonal problems are known to contribute to hair loss. Too much or too little thyroid hormone is a common cause of generalized thinning or loss of scalp hair. This is usually easily diagnosed with a simple blood test. Elevated testosterone tends to cause loss of scalp hair and promote growth of facial and body hair. High levels of insulin, often found in people with diabetes, can also cause hair loss. In women with polycystic ovary syndrome, there are elevations of both testosterone and insulin.
2. Scalp inflammation. Several inflammatory skin conditions, such as eczema, seborrhea, and psoriasis, cause patches of hair loss with red and scaly skin underneath. Fungal scalp infections (also called ringworm) and bacterial infections of the hair roots (folliculitis) can also cause similar problems. Patches of hair loss without underlying redness may be due to an autoimmune condition called alopecia areata.
3. Medications. Several medications can contribute to hair loss. Steroids and chemotherapy are among the most common culprits. Some diuretics (like sprinolactone) decrease levels of testosterone, and can reduce body hair, but usually don’t have much effect on scalp hair. (Editor’s note: this version corrects previous sentence, adding “decrease” and deleting “increase.”) If your hair loss seems to correspond to when you started a new medicine (or increased the dose), it’s worth checking with your doctor about a possible connection.
4. Psychologic factors. Stress, anxiety, and depression are surprisingly common causes of thinning scalp hair, and can be especially difficult to recognize and treat. Many people don’t realize how much stress or anxiety they are actually experiencing, and so will tend to minimize their level of stress when considering possible causes of hair loss. The anxiety is then compounded by the hair loss itself, so the problem becomes even worse!
