Hair loss or thin hair can absolutely be a sign of malnutrition/ digestive problems. This seems to be pretty much universally accepted with not a lot of contentious debate.
The next step? What to do with that information. Address any motility and/or digestive issues first. This includes constipation, diarrhea, heartburn/reflux, nausea, bloating, cramping, and any other symptom that comes from the belly either after eating or that develops throughout the day.
We have plans for each of those issues. Please start there! If the issues are allergies, skin irritations, a poor immune system, mood issues, and headaches/migraines but there are no digestive issues than start there with gut health. We have plans that start there too.
Gut health aside, in the next six months we will be introducing a Hair Complex. It's amazing. Tiffany has been using it for the last six months and has had dramatically noticeable results, noticeably thicker and longer hair.
