NOTICE THINNING HAIR?

In hereditary hair loss, a combination of genetics, hormones, and age causes progressive shrinking of hair follicles, shortening your hair’s growth cycle.

HELPS TREAT HEREDITARY HAIR LOSS

Left untreated, each growth cycle produces shorter, finer, hairs until growth ceases, so start using Regaine® as soon as you notice thinning hair.

USE REGAINE TO HELP REGROW HAIR

Regaine® helps restore inactive hair follicles to lengthen your hair’s active growth phase.

FOR BEST RESULTS STICK WITH IT

Within 3-6 months of using Regaine®, you may begin to see visible results. With continued use, you may enjoy improved coverage with thicker, fuller hair.
