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.

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.

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.

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 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.

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.
