Here are widely recommended, top‑rated men’s shampoos (grouped by common needs). I’ve pulled picks from recent trusted grooming editors and dermatology‑informed roundups so you can match product to hair/scalp type.

Best overall / daily-use

• Highland “The Wash” — high marks from grooming editors for a gentle, ingredient‑forward formula (sulfate/paraben free) that’s good for regular use. (mensjournal.com)

For dandruff / flaky scalp

• CeraVe Anti‑Dandruff Hydrating Shampoo — dermatologist‑formulated, contains pyrithione zinc plus ceramides and niacinamide to treat flakes while hydrating. (mensjournal.com)
• Head & Shoulders Clinical or Classic Clean — budget, clinically proven options with active antifungal/antidandruff actives like selenium sulfide or zinc pyrithione. (vogue.com)
• Horace Gentle/Anti‑Dandruff Shampoo — recommended for men who want a gentler, more natural‑leaning dandruff treatment. (gq-magazine.co.uk)

For thinning or fine hair / thickening

• The Rootist Densify Concentrated Shampoo — editor pick for thinning hair; formulated to increase hair body. (mensjournal.com)
• Kérastase Genesis (Bain De Masse Épaississant) — salon brand frequently recommended for strengthening and plumping fine hair. (menshealth.com)
• Viviscal Thickening Shampoo — budget‑friendly, popular for added body and contains keratin/biotin‑supporting ingredients (many users report fuller look). (instyle.com)

For oily scalp / heavy cleansing

• Baxter of California Daily Fortifying Shampoo — lighter, clarifying option favored by men who shampoo often or have oily hair. (mensjournal.com)
• Aesop Equalising Shampoo or Sachajuan Moisturizing Shampoo — salon/brand picks for effective clarifying without over‑stripping; good if you want premium fragrance/experience. (gq-magazine.co.uk)

Best value / drugstore

• Dove Men+Care 2‑in‑1 Pro Thick Full or Head & Shoulders Classic Clean — reliable, affordable, widely recommended for everyday use and specific needs (thickening or dandruff control). (mensjournal.com)

How to pick the right one

• If you have flakes/itching: choose a shampoo with zinc pyrithione, selenium sulfide, ketoconazole, or salicylic acid and follow label directions (some need to sit on the scalp for a minute). (vogue.com)
• If you want volume/thicker look: look for “thickening” lines or ingredients like biotin, keratin, hyaluronic acid / polymers that add body. Salon brands (Kérastase, Redken) tend to perform best but cost more. (allure.com)
• For daily washes or sensitive scalp: choose sulfate‑free, fragrance‑lean formulas (CeraVe, Highland) to avoid stripping natural oils. (mensjournal.com)
