1. Thinning of eyebrows or eyelashes
If eyebrows or eyelashes are thinning but not because of unsuccessful cosmetic experiments, then it can signal problems with the thyroid gland. Its low activity is a sign of hypothyroidism, which is common among people above 50.
- Among other symptoms, one can note sluggishness, dry skin, and unexplainable weight gain. A blood test and a consultation with your doctor are compulsory in this case.
