Flip your supplement bottle over and look at the label.
Do you see something like this?
"Hair Growth Complex: 500mg
(Pumpkin Seed Oil, Saw Palmetto, Biotin, Collagen, Bamboo Extract, Horsetail, MSM)"
That's a proprietary blend AND it's a massive red flag.
Here's why: When companies hide behind "blends," they don't have to tell you how much of each ingredient you're actually getting. That 500mg could be 450mg of cheap biotin and only 10mg of the pumpkin seed oil that actually works.
Companies use proprietary blends to hide the fact that they're using amounts way below what clinical research shows is effective.
