10 Signs You Might Have a Thyroid Problem

6. Hair, Skin, and Nail Issues.

Since thyroid conditions affect the release of hormones, there might be changes in hair, skin, or nails.

With an underactive thyroid, these changes may include:

• Dry, coarse and brittle hair;
• Loss of hair;
• Thick, dry and scaly skin (especially on the heels, knees, and elbows);
• Brittle and thin nails.

With an overactive thyroid, here are the most common signs:

• Patchy hair loss or thinning;
• Loose nails;
• Increased skin sensitivity;
• Red palms on the hands. [5, 10]
