Shade ranges typically cover light, medium, and dark palettes. Many products use specific shade names such as Blonde, Taupe, Soft Brown, Chocolate, Medium Brown, Dark Brown, Ebony, and Granite to help match different hair tones.
Recommended ages vary by item. Listings may be labeled 'Adult Use Only' or show minimum ages such as 13+, 16+, or 18+. Always check the product packaging or listing for the manufacturer’s recommended age and any warnings.
Net weights and volumes vary by format. Examples seen include 1.3 oz, 0.03 oz, 0.17 oz, 0.04 fl oz (US), and 0.01 fl oz (US); check the specific product listing for the exact size.
Many listings market tattoo brow formulas as easy for DIY use and explicitly state you can apply them at home (for example, peel-off tints often advertise 'no need to visit a salon'), and user reviews commonly note ease of use. Always follow the product’s instructions and warnings on the label.
Common included tools are spoolie brushes (built into or supplied with pencils/pens), brush-tip applicators for gel tints, and dual- or double-brush tips on some pens for precise, hair-like strokes and blending.
