Im 53 years old. Always have had a full head of hair and VERY long bushey eye brows. Yesterday I noticed that the left half of my left eyebrow has almost dissappeared. I take .2 mg Levothyroxine, 10 mg Lisinopril, and 40mg pravastatin each day. I also take 3000 mg Flax seed Oil, 2000 mg Vitamin C and 1 Centrum Silver vitamin per day. any Ideals??
If I was able to examine you, I might find some other areas (like in the scalp) that have patchy hair loss. If it did, then it would be easier to tell you what is happening. Some cases of alopecia areata, for example, will cause a patchy hair loss. Ringworm (tinea corporis), although unusual in your age, can also do it. Too much guessing on my part without seeing you. Although some of the medications are associated with hair loss, for a patch to appear, the cause may be more local than systemic.
