The supplement's marine collagen core and supporting ingredients have clinical backing, but what works depends entirely on why your hair is thinning. Dermatologists praise it for stress-related hair loss and recommend it as one of the few scientifically-grounded hair supplements available, though results vary widely, some people see meaningful improvement while others notice nothing, especially if their hair loss stems from genetics rather than nutritional gaps. The main practical catches: you take four large pills daily, which some find difficult, the cost adds up for long-term use, and it's not safe during pregnancy or breastfeeding due to saw palmetto's effect on hormones.
