❓ Frequently Asked Questions

How soon will I see results?

Most users notice reduced shedding and improved scalp comfort within the first week. Visible thickening and volume improvements are typically seen within 2–4 weeks of consistent daily use.

Can I use this if I have a sensitive scalp?

Absolutely. The formula is free from parabens, sulfates, and silicones, and is specifically designed to be gentle on sensitive scalps. Ginseng and Green Tea extracts actively soothe irritation and redness.

Is it safe for color-treated or chemically processed hair?

Yes. The clean, gentle formula is 100% safe for color-treated, bleached, or chemically processed hair. It will not affect your color or treatment results.

Do I need to rinse it out?

No rinsing required. The lightweight serum absorbs rapidly into the scalp without leaving any sticky or greasy residue, so you can apply it and style your hair immediately after.

How many times a day should I apply it?

Once daily is recommended — either in the morning or before bed. Consistent daily application is key to achieving the best results within 2–4 weeks.

What makes the roll-on applicator different?

The precision metal cooling tip delivers active ingredients directly to the scalp with micro-targeted accuracy, while simultaneously stimulating micro-circulation through a gentle massage effect — far beyond traditional dropper or spray applicators.
