In women on Glow15, hair thinning is likely due to a shift in hormones. The program on Glow15 is compatible with proper hormone-balancing support for aging women. Increase your fiber intake and ensure you are having a bowel movement daily to detoxify hormonal metabolites that can increase your risk for higher estrogen metabolites. Elevated estrogen metabolites can be toxic to your system as well as interfere with other important hormones such as your thyroid and stress hormones. All of which can be contributing to thinning hair.
