Frequently asked questions

Micro-infusion is a precision way to apply serum. A grid of fine micro-tips stamps the formula directly onto the scalp, instead of leaving it on your hair like many droppers and sprays.

Open a fresh 5 ml vial, fill the reservoir, twist on the applicator, then part your hair and gently stamp across the areas you want to target. Pat it in and you're done. It takes about five minutes and there's nothing to rinse.

Once a week. Each vial is one application, so a 4-vial kit lasts one month. Consistency matters most, which is why the 2- and 3-month kits are popular.

Most people describe a light, prickly tapping sensation. Press gently, never drag the applicator, and don't use it on irritated, broken or sunburned skin.

The system is designed for all hair types and textures. If you have a scalp condition or sensitive skin, patch test first and check with your dermatologist.

Every kit includes 4 serum vials and 1 applicator per month of supply, plus a quick-start guide. The 2-month kit has 8 vials and 2 applicators; the 3-month kit has 12 vials and 3 applicators.
