What People Say
Synthesized from 32 reviews · 100% verified purchases.
For dandruff, Nizoral is highly effective but always pair it with a strong hydrating conditioner to prevent dryness. Salon-quality brands like Olaplex are worth the investment for damaged hair, but start with a small bottle since a little product goes a long way.
- Fast and effective relief from dandruff and scalp issues
- Leaves hair noticeably softer, stronger, and shinier
- Pleasant, mild scent that is not overpowering
- A small amount of product goes a long way, making it economical
- Excellent detangling, reducing breakage and easing combing
- Medicated formulas can severely dry out hair if not paired with a heavy conditioner
- Salon-quality products are expensive, which may be a barrier for some
- Spray nozzle design makes even distribution difficult
