Hormonal disorders and thyroid disease are among the common causes of hair loss in millennials. However, diet, stress, and hair routines are key factors in why people are balding earlier in life. The growing popularity of vegetarianism and veganism might also be a contributing factor in millennial hair loss. 

A study conducted by Dr Emily L. Guo suggests that reduced protein, zinc, and nutrient consumption can affect hair growth. 

APA researchers discovered that generation X and millennials are also experiencing higher levels of stress than the generations before them. 

“Stress can interrupt the hair growth process by moving hairs out of the growth phase prematurely. This can cause higher amounts of hair to fall out,” said Dr Doris Day MD in an interview with Healthline.

Day says the maintenance routine adopted by millennials may also be contributing to premature hair loss. “Excessive bleaching and dying can seriously damage hair,” she said. “The weight and tension of hair extensions can also weaken hair follicles, causing more hair to fall out.”

“Anyone concerned about thinning hair or balding should see a dermatologist to discover what can be done,” Day added. “There are medical, nutritional, and other interventions that can help.”
