What is worth knowing

A woman's hair part, close up

The shedding isn't your fault, and it isn't forever

It tends to peak around 4 months after birth, and most new moms are back to normal fullness by the first birthday.1 No serum can take credit for that. See a doctor if it is patchy, or still heavy after a year.

What PowerCycle does in the meantime

It is a scalp serum for thicker, fuller-looking hair. Once a day, on damp or dry hair. No rinsing, no residue, style as usual, which also means no extra hair wash in a week that has none to spare.

What DropOff does for stretch marks

A light gel-serum that absorbs quickly and visibly smooths the look of stretch marks. Twice a day, massage it in circular motions until absorbed. It won't erase them. It is made to help them look softer.

What to expect, and when

Use PowerCycle once a day and DropOff twice a day, and give both at least 4 weeks. The technology in PowerCycle was measured at day 28 and day 56. Results vary from person to person.

Questions, answered

Can I use these while breastfeeding?

Please check with your doctor first. We can't give medical advice on using these while pregnant or nursing.

Will PowerCycle stop my shedding?

No, and we won't promise that. Postpartum shedding usually settles on its own. PowerCycle is about how your hair looks and feels while it does.

Will DropOff remove my stretch marks?

No. It visibly smooths how they look. Results vary from person to person.

How long until I see a difference?

The technology in PowerCycle was measured at day 28 and day 56. Use it every day and give it at least 4 weeks.

What if it is not for me?

Returns are free within 30 days of purchase. Opened products qualify if less than 1/4 is used. Original shipping is not refunded.

Individual results vary. SickScience products are cosmetics. They are not intended to diagnose, treat, cure or prevent any disease.
