We evaluate supplements across specific hair and scalp conditions. Each condition page ranks ingredients by evidence grade, helping you find what research actually supports for your particular concern.

How We Grade Evidence

Cada página de condición clasifica los ingredientes de suplementos según la solidez de la evidencia clínica. Esto es lo que significa cada calificación:

Strong Evidence

Multiple randomized controlled trials (RCTs) or meta-analyses with consistent positive results and large sample sizes.

Good Evidence

At least one RCT with mostly consistent results across studies. Evidence suggests benefit but more research may be needed.

Some Evidence

Small studies or observational data with some positive signals. Promising but insufficient for strong recommendations.

Very Early Research

In vitro studies, case reports, or pilot studies only. Early-stage research that requires clinical validation.
