Reddit’s shampoo talk is led by Nizoral A-D, with Selsun Blue and Head & Shoulders valued for controlling stubborn flakes, itch, and greasy scalps through medicated actives.
The why
A medicated 1% ketoconazole shampoo for recurring dandruff, seborrheic dermatitis, and an itchy scalp. It fits people needing an occasional treatment wash, but dry, curly, or fragrance-sensitive users may find its sodium laureth sulfate and fragrance harsh.
One minus
Can leave hair dry, frizzy, straw-like, and tangled
Medicated Antidandruff Shampoo
1% selenium sulfide clears stubborn dandruff fast; drying and unreliable for some scalps.

Olaplex No. 4 appeals to processed hair and hard-water buildup, but some report dryness, frizz, or scalp irritation. Medicated washes suit dandruff-prone scalps, while clarifiers like Suave are best kept occasional because users find them intensely stripping.
