Jostylin’s Batana & Rosemary Hair Growth Oil

Nature holds powerful secrets, and at Jostylin, we combine ancestral wisdom with modern research to unlock them. Our Batana & Rosemary Hair Growth Oil is crafted for those who understand that healthy hair begins with a healthy scalp.

Our Philosophy: Science Meets Tradition

Hair loss and scalp issues are complex. No single ingredient is a magic solution.
Instead, our approach focuses on delivering key fatty acids, antioxidants, and bioactive compounds that work together to create the best possible conditions for healthy, strong hair.
Every ingredient in our formula has been selected based on scientific studies, traditional use, and its natural compatibility with hair and scalp biology.

Key Ingredients and Their Functions

1. Dual-Origin Batana Oil (Honduran + West African)

Batana oil, traditionally used by the Miskito people of Honduras (“the Tawira” or “People of the Beautiful Hair”), has a long-standing history in hair care rituals.
However, not all Batana oil is the same — the origin affects its chemical makeup.

Honduran Batana Oil (Elaeis oleifera)

• Oleic Acid (45–75%): A monounsaturated fat. This study shows oleic acid enhances the absorption of topical treatments like Minoxidil into hair follicles.

• Linoleic Acid (22–32%): This research found linoleic acid improves scalp lipid metabolism, supporting follicle health and potentially improving hair density.

• Palmitic Acid (6–14%): Contributes to moisture retention and scalp barrier protection.

• Myristic Acid (2–5%): Linked to the stimulation of dermal papilla cells, which are critical in hair growth cycles (study).

West African Batana Oil (Elaeis guineensis)

• Lauric Acid (~46%): This study shows lauric acid bonds tightly with hair proteins and easily penetrates the hair shaft, strengthening hair and reducing protein loss.

• Myristic Acid (~16%): Plays a role in modulating testosterone and DHT levels, according to this research, which could benefit scalp health in cases of androgenetic alopecia.

• Oleic Acid (~15%) and Palmitic Acid (6–14%): Support overall scalp hydration and follicle protection.

Why We Blend Both Oils

Each oil species offers something unique.
Honduran oil’s higher oleic and linoleic acids boost ingredient absorption and lipid metabolism, while West African oil’s rich lauric and myristic acids protect the hair shaft and support a healthier scalp microbiome.

By blending both, we create a balanced oil that:

• Deeply penetrates the hair shaft

• Supports scalp lipid balance

• Delivers antimicrobial protection

• Helps active ingredients reach deeper into hair follicles

2. Organic Rosemary Oil

Rosemary oil has earned its place in scalp care through centuries of traditional use — and now, clinical trials confirm its value.

• A 2015 randomized trial (study here) compared rosemary oil to Minoxidil 2% and found similar improvements in hair count after six months.

• Rosemary oil helps improve blood circulation in the scalp, ensuring hair follicles receive more oxygen and nutrients.

• Its anti-inflammatory and antioxidant properties may reduce oxidative stress, one of the silent contributors to hair thinning over time.

3. Burdock Root Infusion

Burdock root has been used in Asian and European folk medicine for generations to promote a healthy scalp and stimulate hair vitality.

• Rich in phytosterols and essential fatty acids, burdock root supports skin barrier function and calms inflammation.

• A 2023 study showed that burdock extract can stimulate dermal papilla activity, an important mechanism for healthy hair cycling.

• Burdock is also a natural source of arctiin, a compound linked to improved hair structure and scalp condition.

The Science Behind the Fatty Acids

Lauric Acid

• Antimicrobial Action: Lauric acid is proven to fight bacteria and fungi that disrupt scalp health (study).

• Hair Penetration: Its small molecular size allows it to deeply penetrate hair shafts, helping protect from protein loss and breakage (study).

Oleic Acid

• Absorption Enhancer: Acts as a carrier, helping other beneficial oils and ingredients penetrate more efficiently (study).

• Moisture Retention: Prevents scalp dryness, maintaining a healthier scalp environment.

Linoleic Acid

• Lipid Metabolism Support: Essential for maintaining healthy lipid layers in the scalp. Deficiencies are linked to scalp barrier issues and slower hair cycling (source).

Myristic Acid

• DHT Regulation: Studies suggest myristic acid can interact with testosterone to reduce DHT formation, supporting healthier follicle function in those prone to androgenetic alopecia (research).

How to Use

• To melt the oil, place the bottle in a jug of warm water.

• Apply from roots to ends if targeting overall hair strength.

• Use 2–3 times a week as part of your regular scalp and hair care routine.

• For enhanced absorption, apply to slightly damp hair or scalp after washing.
