The signature ingredient

Jatamansi

A Himalayan root, traditionally used in Ayurvedic hair care.

Jatamansi is a fragrant rhizome long valued in Ayurveda and traditionally used in hair and scalp rituals. Unlike a leaf or flower, the rhizome is the plant's underground stem — dug from the earth and carefully dried before it is prepared.

We use the whole botanical in our formulation, drawing on its long Ayurvedic history and its traditional place in hair care — a root used to care for roots.

From the earth, back to the roots.

What does the Root Renewal Serum do?

The Root Renewal Serum is a lightweight botanical scalp serum that helps nourish the roots, reduce hair fall associated with weakness and breakage, invigorate the scalp and support healthy-looking hair growth over time.

How long before I see results?

Hair growth is a gradual process and results vary from person to person. With consistent use, visible changes are typically expected over 8–12 weeks as the serum supports the natural hair growth cycle.

Is it suitable for all hair types?

Yes. The Root Renewal Serum is formulated for all hair types and textures, including colour-treated hair.

Will it make my hair greasy?

No. The serum has a lightweight texture designed to absorb into the scalp without leaving an oily finish.

Can I use it with the Root Vitality Oil Shots?

Yes. They are designed to complement each other rather than overlap. The Root Renewal Serum is a leave-in scalp treatment, while the Root Vitality Oil Shots are a pre-wash oil ritual. Together, they form the Scalp Renewal Ritual.

Is the Root Renewal Serum natural?

The formula brings together botanical oils, Ayurvedic herbs, plant extracts and essential oils, chosen for their role in nourishing the scalp and supporting healthy-looking hair.

The science

Why roots matter

Hair begins at the root, where each strand develops within the scalp. The health of the scalp and the nourishment around the roots play an important role in supporting stronger, healthier-looking hair.

The Root Renewal Serum takes a root-first approach, bringing together botanicals chosen for different aspects of scalp and hair care — from invigorating the scalp and nourishing the roots to supporting the natural hair growth cycle.

Peppermint, ginger and cayenne help invigorate the scalp. Jatamansi, sesame and botanical oils nourish the roots, while saw palmetto and pea sprout extract support healthy-looking hair growth. Aloe vera and green tea help keep the scalp feeling balanced and cared for.

Start at the roots. Care for the hair from where it begins.

Light, refreshing and easy to use. I love the cooling, herbal feel when I massage it into my scalp. It absorbs quickly and doesn't leave an oily residue.

I noticed less hair fall with regular use. It took some patience, but after using the serum consistently, I started noticing less hair fall and my hair feels stronger overall.

My scalp feels so much healthier. I’ve been using it consistently and the first thing I noticed was how fresh and nourished my scalp feels. Hair fall also seems to have reduced.
