Our Take

Why it made the edit.

Why we love it: It's a no-rinse spray, so daily use is realistic. The formula is focused on the scalp, where hair health starts.
Skip it if: Your hair loss is sudden, patchy or worrying you, so talk to a doctor before buying anything.
The catch: $120 for 3 oz is a big ask, and you won't know if it's working for months.
