Two serums. One routine.

Density Serum every morning, Shed Serum at night while shedding is active. Most women take the System, because that is the routine we would give a friend. If you would rather start with one bottle, the Density Serum is $58 and is a complete routine on its own.

The offer

Ninety days is the test. So we sell ninety days.

Every claim on this page says the same thing: a scalp serum takes about three months to judge, and month two is where people quit. Selling you thirty days at a time makes you re-decide twice before you can fairly judge it. So the protocol is the default, it costs less per month, and it is one payment with nothing to cancel.
