The Eyebrow Test If your eyebrows are consistently thick and well-groomed, it may indicate high testosterone levels. However, this can also be a sign of health problems such as polycystic ovary syndrome (PCOS), which is linked to hormonal imbalances and excess male hormones in women. In men, thinning eyebrows can signal low testosterone or thyroid issues. Eyebrows that are sparse or patchy on one side could be an indicator of nerve damage.
