Our ingredients work

Six botanicals. Zero fillers.

Rosemary Oil

The growth stimulator

A circulation-boosting botanical that wakes up the scalp and supports healthy follicle activity.

Nigella Sativa

The queen of herbal medicine

Black seed oil — a centuries-old remedy rich in thymoquinone, antioxidants, and essential fatty acids.

Castor Oil

The thickener

A dense, ricinoleic-acid-rich oil that coats and strengthens strands for visibly fuller hair.

Sweet Almond Oil

The softener

A light, vitamin-E-rich oil that softens, smooths, and improves hair elasticity.

Coconut Oil

The protector

One of the only oils proven to penetrate the hair shaft and prevent protein loss.

Peppermint Oil

The awakener

Cooling and invigorating — refreshes the scalp and amplifies rosemary's stimulating effect.

My baby hairs are BACK

Three months of consistent use and my edges have visibly filled in. I was skeptical after trying literally everything, but this oil is the real deal. The rosemary tingle tells you it's working.

Replaced 4 products on my shelf

I used to layer a scalp oil, a serum, and two different leave-ins. Now it's just this. My hair has never been softer and my scalp never itches anymore.

Shedding cut in half

I used to dread washing my hair because of how much came out in the shower. After 8 weeks with the Elixir, the shedding has noticeably slowed. My hairdresser asked what I changed.

Great oil, wish the bottle was bigger

Love the formula — lightweight, smells amazing, and my curls drink it up. Only complaint is I go through it fast because I use it on my daughter's hair too!

Postpartum hair saver

Postpartum shedding hit me hard at 4 months. This oil became my weekly ritual and the regrowth along my hairline is honestly emotional. Thank you kaesbeauty.

Shine for days

I bought it for growth but the SHINE is what sold me. Two drops on dry ends and my hair looks like a gloss treatment. I've converted my mom and two sisters.
