Product descriptions most often recommend daily use or using the shampoo every other day; several listings explicitly show “Daily,” some show “Every Other Day,” and a few list both as options.
Common retail sizes in the listings include 8.5 fl oz, 8 fl oz, 12 fl oz, and 16 fl oz.
Many product descriptions state formulas are gentle on color-treated hair, emphasizing sulfate-free, non‑stripping formulations designed to protect color while hydrating dry, color-treated strands.
Romero (rosemary) shampoos are offered in liquid, cream, and gel formulations across the listings.
