Hair thinning and loss in women over 40 is not just common—it’s nearly universal. Studies show that approximately 40% of women experience noticeable hair loss by age 50, with that number climbing to over 50% by age 60.

This pattern can be devastating for self-esteem and quality of life, yet it’s rarely discussed openly.

Yet despite its importance, silica levels naturally decline as you age, with skin silica content dropping by approximately 50% by age 50.
