Consumer advice
Check if you can just buy a saw palmetto supplement (the one ingredient here with actual hair-growth trial data) instead of paying for a multi-ingredient gummy with no disclosed doses. Ask the med spa for the actual mg amounts per gummy before buying — if they won't share them, that tells you the doses are likely too low to matter. Don't expect this to meaningfully treat pattern hair loss; if that's your goal, ask about minoxidil or finasteride, which have much stronger evidence.
