- Scalp condition: For dermatitis-prone scalps, prioritize formulas with anti-inflammatory or soothing components and avoidance of potential irritants.
- Hair type and goals: Lightweight blends suit fine or oily hair, while richer blends may benefit very dry or damaged scalps.
- Application method: Leave-in vs. wash-out options; consider your wash routine and how often you prefer to treat your scalp.
- Allergic considerations: Conduct a patch test if you have sensitive skin or known rosemary sensitivities.
- Additional benefits: Some products include biotin, vegan collagen, or antimicrobial oils, which may support overall hair health beyond scalp comfort.
