1. Eyebrow thinning

According to Livestrong.com, medical conditions like hypothyroidism and atopic dermatitis can contribute to thinning eyebrows. A thyroid gland that is underactive, or hypothyroidism, can cause general hair thinning. Additionally, atopic dermatitis, a skin disease that affects 20% of the population, may be a factor in eyebrow loss.
2. Intense acne and unusual hair

It’s normally okay to have peach fuzz and minor acne. But if you have a lot of facial hair or severe acne, you might have a health problem. It can be a sign of PCOS, a condition marked by irregular periods, obesity, infertility, and abnormal hair growth. As soon as you notice these symptoms, call your doctor.
3. Red rashes and bumps

A red rash on your face or neck could be a sign of autoimmune diseases like lupus or celiac disease or digestive problems. Keep up with these possible health issues.
