Hello I Have Been Experiencing Dry Itchy Face Especially On

Hello I have been experiencing dry itchy face especially on my jaw line. Then some excess weight gain along with constipation. I am in menopause and have had some hot flashes on and off. I also have noticed the end of my eye brow is thinning very suddenly. My question is could this all be related to menopause or could I have a thyroid problem going on. The itching face seems to be constant although there is no visible evidence of a rash or anything.
