What practical steps should I follow before and during application to get the best results and avoid unwanted reactions?

Before using Elfarm INDIAN HENNA Light Brown, start with a patch test to check for sensitivity, especially if you have a reactive scalp or a history of colourant allergies. Mix a small amount of powder with water to form a paste and apply it to a discreet area of skin, leaving it for the recommended time. If irritation occurs, discontinue use. For hair that is bleached, heavily lightened, or chemically processed, test the colour on a small hidden section first, as results may vary. When ready to colour, mix the powder fresh to create a smooth paste and apply evenly to clean, dry hair. Make sure to cover all areas for consistent colour. Wear gloves to avoid staining your hands and protect clothing and surfaces, as henna can leave marks. Leave the paste on for the recommended processing time, then rinse thoroughly. The final colour will depend on your natural hair shade and condition, so expect some variation. If irritation appears during or after application, stop using the product. For external use only. Consult a specialist before use if you have chronic conditions, are pregnant, breastfeeding, or take medication.
