Jack Henry Deodorant — Functional & Balancing

This deodorant is built around a functional approach. It uses probiotics, enzymes, and plant-based odor absorbers to help neutralize odor rather than simply covering it up. According to the brand, it is aluminum-free, baking soda-free, pH-balanced, goes on clear, and is designed for all-day wear.

Ingredients:

Caprylic/Capric Triglyceride (Coconut MCT Oil) • Arrowroot Starch • Magnesium Hydroxide • Oryza Sativa (Rice) Bran Wax • Cetyl Alcohol • Butyrospermum Parkii (Shea Butter) • Limnanthes Alba (Meadowfoam Seed Oil) • Zinc Ricinoleate • Lactobacillus Ferment (Probiotics) • Citric Acid (from fruit) • Fragrance (100% natural botanical derived)

What I like

• EWG Analyzer rating: 1
• Uses mostly plant-based oils and butters like coconut MCT, shea butter, and meadowfoam seed oil
• Free from aluminum and baking soda, which can be a better fit for sensitive underarms
• Includes Lactobacillus ferment, which supports odor control by working with the underarm microbiome rather than blocking sweat
• Focuses on odor control while allowing the body to sweat naturally

Things to keep in mind

• The scent is created from 100% botanical sources, but fragrance can still be noticeable. Patch testing is recommended for fragrance-sensitive skin
• Magnesium hydroxide and starch-based formulas work well for many people, but if you’ve reacted to natural deodorants in the past, patch testing is wise

Sensitivity & Pregnancy Considerations

This formula contains botanical fragrance and magnesium hydroxide. If you are prone to irritation, eczema, dermatitis, or have very sensitive underarms, patch testing is recommended. Avoid applying immediately after shaving, as freshly shaved skin can be more reactive.

Essential oils and botanicals can carry trace contaminants depending on sourcing and processing. Feather & Nest prioritizes brands that emphasize ingredient transparency and purity-focused practices to help minimize impurities whenever possible.
