Ingredient & Allergen Information

Homegirls, we'd rather tell you exactly what's in the bottle and why than hand you a marketing paragraph and hope you don't ask. Here's the real breakdown.

Growth Oil — Key Actives

• Rosemary Oil — studied in a published randomized trial against minoxidil 2%, with comparable results on hair count after six months. Allergen note: essential oils like rosemary are generally advised against in concentrated use during pregnancy without consulting your doctor first.
• Peppermint Oil — shown in controlled research to support hair growth. Allergen note: can cause a tingling or cooling sensation; if you have sensitive skin, patch test first and discontinue if irritation occurs.
• Jamaican Black Castor Oil — rich in ricinoleic acid, studied for scalp conditioning and circulation support. Allergen note: avoid if you have a known allergy to castor bean derivatives.
• Hemp Seed Oil — a natural source of omega-3 and omega-6 fatty acids. This is the seed oil, not a psychoactive extract — it contains no THC.
• Oleic-Acid-Rich Oils — chosen specifically because oils high in oleic acid penetrate the hair shaft rather than just sitting on the surface, per published research on hair oil absorption.

Edge Control — Key Actives

• Argan Oil — supports shine and conditioning without heavy buildup.
• Basil Leaf Oil — included for scalp conditioning alongside the hold formula.

Our Edge Control is alcohol-free by design — alcohol-heavy formulas are the most common cause of flaking and dryness at the hairline, so we build around avoiding it.

General Allergen Guidance

Everyone's skin and scalp are different. Before using any new product on your hairline:

• Do a small patch test 24-48 hours before full application, especially if you have known sensitivities to plant oils or botanical extracts
• Discontinue use and consult a dermatologist if you notice redness, itching, or irritation that doesn't resolve
• If you're pregnant, nursing, or have a diagnosed scalp condition, check with your doctor before starting any new hair care routine
