A big gulp of water for hair that struggles to stay hydrated for long.


Moisture Base is a big gulp of water for your hair routine — a lightweight leave-in serum made to put moisture back into hair and help keep it there when the environment keeps taking it out.

At the heart of the formula is our blend of strengthening low-molecular-weight peptides, amino acids and moisture-magnet polyglutamic acid. Together, they reinforce the hair structure, flood it with hydration and help it hold onto that moisture for longer. Biomimetic ceramide support and lightweight conditioners help keep hair softer, more flexible and easier to manage.

Use it as your first layer after washing, or whenever your hair starts to feel thirsty.

Inside The Formula

A deeper kind of hydration from every angle.

Our signature lightweight blend that gives hair a deep injection of moisture and structural support, helping it stay strong, supple and ready for whatever the day brings.

Low-Molecular-Weight Amaranth Extract

Protein-rich micro-peptides extracted from Amaranth that can penetrate the hair fiber and work hard beyond the surface, helping strands feel fuller and more resilient from within.

Polyglutamic Acid

5x more powerful than Hyaluronic Acid, sodium polyglutamate helps bind moisture and keep hair hydrated for longer, without weighing it down.

Prebiotic + Biomimetic Ceramide

Helps support the hair and scalp environment while reinforcing the cuticle’s natural lipid barrier, so moisture has a better chance of staying where you put it.

Moisture Base Hair Serum FAQs

Can I use Moisture Base with other styling products?

Yes. Groundwork is intended to sit at the base of your routine. Apply it first to add moisture, then follow with your usual styling cream, gel, oil or heat protectant. It can also be used alone when hair needs hydration but very little hold or weight.

Is Moisture Base suitable for curly or textured hair?

Yes. All hair types need moisture, including thick, curly, coily and textured hair.

Groundwork uses water-based hydrators, squalane, amaranth peptides and lightweight ceramide support to help hair hold onto softness and flexibility without relying on a heavy or waxy coating.

Fine hair types can use a small amount as a lightweight leave-in, while thicker or more textured hair can apply more generously or use it as the hydrating first layer beneath a richer cream, oil or styling product.

Will Moisture Base make my hair feel heavy or coated?

Groundwork is designed to provide moisture without the dense, coated feel of a traditional leave-in cream. Its lightweight blend of hydrators, squalane, ceramide and amaranth extract absorbs into the hair as a breathable base, leaving it soft and flexible rather than greasy or weighed down.
