Best Natural Oils for Hair Regrowth: A Scientific Guide

If you’re searching for the best natural oils for hair regrowth, science and tradition both point to ingredients like rosemary oil, castor oil, peppermint oil, and tea tree oil. These oils are known to stimulate follicles, improve scalp circulation, and strengthen strands from root to tip. For those who want an easy, science-backed routine, the Lustrao Hair Growth Trio and Hair Growth Duo combine these oils into a complete, ready-to-use system.

Why Natural Oils Help Hair Regrowth

Natural oils are rich in bioactive compounds, fatty acids, and antioxidants that target the key causes of hair thinning: poor circulation, DHT buildup, scalp inflammation, and protein loss.

Dr. Alan Bauman, a board-certified hair restoration physician, explains:

“When applied topically, essential oils like rosemary and peppermint can improve blood flow to the scalp, prolong the growth (anagen) phase of the hair cycle, and reduce follicle miniaturization.”

This makes oils a powerful and side-effect-free alternative to synthetic treatments.

The Best Natural Oils for Hair Regrowth

1. Rosemary Oil

Rosemary oil has been shown in studies to increase hair count by 44% in six months, performing as well as 2% minoxidil without side effects. It works by improving scalp circulation and protecting follicles from oxidative stress.

You’ll find rosemary oil in:

• Lustrao Hair Regrowth Oil – blended with peppermint, castor, olive, and ginseng.
• Lustrao Growth Shampoo – a refreshing daily cleanser with rosemary, peppermint, silk protein, and vitamins.
• Lustrao Hair Growth Trio – combines shampoo, conditioner, and oil for maximum regrowth.

2. Castor Oil (and Black Castor Oil)

Castor oil is rich in ricinoleic acid, which boosts circulation and acts as a natural anti-inflammatory. Black castor oil, processed differently, contains higher levels of ash and is often praised for thicker, coarser hair types.

A 2020 study in the Journal of Ethnopharmacology confirmed castor oil’s ability to support scalp hydration and reduce hair breakage.

Lustrao uses castor oil in the Hair Regrowth Oil, creating a targeted blend to support both regrowth and strand strength.

3. Peppermint Oil

Peppermint oil is one of the most clinically proven natural stimulants for hair follicles. In animal studies, it increased the number of follicles, follicle depth, and overall hair thickness by 92% in just 4 weeks.

It’s a star ingredient in both the Growth Shampoo and Regrowth Oil, delivering that cooling, circulation-boosting effect that helps “wake up” dormant follicles.

4. Tea Tree Oil

Tea tree oil has strong antimicrobial and anti-inflammatory properties, helping clear blocked follicles and maintain scalp health. A healthy scalp is essential for consistent regrowth.

You’ll find tea tree oil in the Lustrao Growth Conditioner, which nourishes while balancing scalp oils.

5. Argan Oil

Argan oil reduces protein loss from hair by up to 60%, making it essential for reducing breakage and split ends. Rich in vitamin E and antioxidants, it strengthens hair fibers while locking in moisture.

It’s used in Lustrao formulas to complement stronger stimulants like rosemary and peppermint, ensuring not just growth but healthier, shinier strands.

How to Use Natural Oils for Hair Growth

For the best results, consistency is key. Experts recommend combining oils with gentle cleansing and conditioning for a complete scalp and follicle regimen:

• Daily treatment: Massage Lustrao Hair Regrowth Oil into the scalp.
• Wash routine: Use Lustrao Growth Shampoo 3–4 times a week.
• Conditioning: Follow with Lustrao Growth Conditioner to hydrate and protect.
• Kits: For simplicity, choose the Lustrao Duo or Trio Consistency Kit — pre-formulated for results.
