Root Renewal Scalp Serum:Â for dry scalps, graying hair, or for a restorative reset.
A scalp-focused ritual for renewal and growth. Handcrafted with fresh hops and whole-plant botanicals like amla, bhringraj, and cacao, this deeply restorative blend nourishes the roots, awakens circulation, and restores harmony where healthy hair begins.
Rich and treatment-focused, this serum is designed specifically for the scalp — to massage in, let absorb, and wash away — leaving the scalp balanced, revitalized, and deeply grounded.
Use weekly or whenever your scalp calls for extra care — to reset, to reconnect, to begin again at the roots.
Perfect For: Dull or thinning hair, dry scalp, and anyone seeking to stimulate healthy growth.
How to Use: Massage directly into scalp, leave for 15+ minutes, then double cleanse with Under Luna Shampoo + Conditioner. Use weekly for best results (see more detailed ritual below).
Aromatics:Â hops + cacao + neroli

How to apply
Over time, scalp circulation and follicle strength can decline — especially through stress, hormonal shifts, or seasonal change.
Usethe Growth Serum once a week as part of your self-care ritual.
It’s best applied on a dry or damp scalp — before washing, or any time you want to give your roots an herbal reset.
This weekly ritual supports your roots before thinning appears, giving your scalp the care it needs to stay balanced and strong:
1. Part hair into sections.
2. Start with a few drops and apply directly to the scalp, focusing on areas that need extra love. Add more as needed.
3. Gently massage for 2–3 minutes to boost circulation and absorption.
4. Leave it on for at least 15 minutes before washing your hair. Use your Under Luna Shampoo and make sure to double shampoo to remove excess oil, then apply your Under Luna Conditioner.
(For deeper nourishment, you can leave it on longer — even overnight.)
Tip: Consistency matters more than quantity. Start with just a few drops — a little goes a long way.
