from your symptoms I’d say there’s a good chance you have Candida, lack of probiotics in your intestines, mental stress which causes you to tense up your facial muscles which pulls down the scalp which limits blood/lymph flow which has bad effects on hair roots, stress caused high cholesterol, food allergies causing dark eye circles, low thyroid hormone causing coldness, overly acidic diet causing the low PH.
