Key purchase considerations
- Active ingredients: Look for explicit hair-growth actives (e.g., Redensyl, collagen blends, ginseng, or botanical extracts) and how they align with your scalp needs and tolerances.
- Scalp type and sensitivity: Choose pH-balanced formulas designed for sensitive scalps if you experience itchiness, irritation, or dandruff.
