60 seconds
Apply 1–2 droppers on the scalp every morning, massage, leave in, and style as usual.
Founder note
I made Boon Labs after seeing what thinning hair did to my mom.
One night after her shower, she pulled hair from the drain, put it on the sink, and looked at her scalp through her hair in the mirror. She cried. Her doctor said it was normal for her age. I wanted a simple scalp routine that respected what she was actually seeing every morning.
Start with one bottle. Take a day-1 photo in the same light. Give your scalp the same 60 seconds every morning.
