Results may vary for each individual.

79% of participants in our clinical trial saw reduced hair loss after just 30 days.

75% experienced a measurable increase in hair density after 90 days.

Many of our customers first notice less hair shedding in the shower—often within just a few weeks of use.

The Hair Grow Serum formula is effective for most types of hair loss, as long as the hair follicles are still active. In the early stages of hair loss, follicles are more likely to support new growth. That’s why starting early can lead to the best results.
