What is the safest way to apply it without staining my skin, clothes, or bathroom? — TINT SEMI-PERMANENT EFFECT COLOR Bad Girl NEON GREEN 150ML

Strong direct pigments stain porous surfaces — skin, towels, countertops, grout, and clothing. Before first use, apply a small amount behind the ear or on the inner forearm, leave for the recommended development time, rinse, and wait 48 hours to check for any reaction. On application day: wear the gloves provided (or nitrile gloves), drape an old towel over your shoulders, and apply petroleum jelly or a thick barrier cream along the hairline, ears, and neck. Work on dry, unwashed hair — natural oils give slight protection and help even distribution. Section hair and saturate evenly from roots to ends using a tint brush or gloved fingers. Avoid overlapping previously coloured sections excessively to prevent uneven buildup. Leave on for the time indicated on the packaging (typically 15–30 minutes), then rinse with cool water until it runs clear — no shampoo needed for the first rinse. Wipe any splashes immediately with a damp cloth; dried pigment is much harder to remove.
