Episode notes
Women Need Hormone And Iron Checks First
- Women face extra variables: menstruation, pregnancy hormone swings, childbirth, and hormonal birth control all alter iron and hormone balance and raise hair-loss risk.
- Prioritize iron/ferritin and hormone evaluation when women present with thinning.
Reduce Stress To Prevent Massive Shedding
- Manage stress to prevent telogen effluvium and alopecia areata; severe stress can cause shedding of 33–50% of hair within a year.
- Improve sleep and reduce chronic stress to protect stem cell activation and reduce shedding and graying.
Use Red Light As A Complement Not A Cure
- Use red light therapy appropriately: low-dose clinic lasers or 80-diode devices twice weekly can stimulate blood flow and ATP production.
- Red light boosts results only after you address underlying nutrition and inflammation; otherwise it can worsen outcomes.
