An itchy scalp usually means one or more of these are in play: dehydration, product build-up, or yeast-driven dandruff. The right shampoo should match the cause. Start simple with a fragrance-free, gentle cleanse. If flakes persist, step up to salicylic acid for build-up or ketoconazole for stubborn dandruff and itch. Keep water lukewarm and always follow with a light, scalp-friendly conditioner on the lengths only.
Below are three editor-curated shampoos that consistently earn strong owner feedback: a non-medicated, sensitive-scalp basic; a salicylic-acid option that loosens flakes; and a ketoconazole formula for recurring itch that won’t quit.

2) Neutrogena T/Sal Therapeutic (3% Salicylic Acid) — Best for build-up & flakes

- Only twice weekly in many routines

FAQs
Do I need a medicated shampoo right away?
Not always. Start with a gentle, fragrance-free shampoo if you’re mostly dry/tight. If flakes and itch persist, move to salicylic acid or ketoconazole.
Can I use conditioner with an itchy scalp?
Yes—just keep conditioner on the lengths, not the scalp, to avoid residue that can worsen itch.
How often should I use medicated shampoos?
Typically 2–3×/week with 3–5 minutes of contact time. Use a gentle shampoo on off days.
Will these strip my color?
The picks here are color-safe when used as directed. Always patch test and rinse well.
When should I see a dermatologist?
If you have severe redness, bleeding, or recurring symptoms that don’t improve after 2–3 weeks of appropriate shampoo use.
