Expert Technique & Theory
Dandruff is not caused by simple dry skin; it is a clinical condition driven by an overgrowth of lipophilic Malassezia yeasts (principally M. restricta and M. globosa) naturally resident in human scalp follicles.
These yeasts feed on triglycerides within scalp sebum, releasing irritating oleic acid as a metabolic byproduct. In susceptible individuals, oleic acid triggers epidermal inflammation and accelerates keratinocyte turnover from 28 days down to just 7 to 10 days, shedding clumps of immature cells as visible flakes.
Ketoconazole directly inhibits fungal ergosterol synthesis, destroying Malassezia cell membranes. It is the gold standard for recurring, itchy seborrhea.
Salicylic acid acts as a keratolytic agent, loosening desmosomes between corneocytes to dissolve thick, adherent crusts. Rotating between an antifungal (Nizoral) and a keratolytic (T/Sal) provides comprehensive scalp clearing.

Active ingredients like ketoconazole and selenium sulfide can feel clarifying on hair fibers. To prevent dryness, apply the medicated shampoo strictly to the scalp and roots, and always use a deeply nourishing conditioner or mask on mid-lengths and ends.
Yes, Nizoral is generally safe for color-treated hair. However, because it clarifies effectively, use it in rotation with a color-safe sulfate-free shampoo to preserve salon color longevity.
