No Exchange or Return How to Use: Mix the contents of the jar well and shake until the henna and oils are fully blended. Take 2–3 tablespoons of the prepared henna (depending on your hair length and thickness). Add boiled onion and garlic water or coconut milk to reach your desired consistency. Apply to the hair for 2–4 hours, focusing on the scalp and roots. Rinse with shampoo, then follow with the collagen mask or a conditioner suitable for your hair type. Use once a week. Warnings: If this is your first time using Indian herbs, apply for only one hour to avoid shedding until your scalp adjusts. For external use only. Safe for children and pregnant women. Store in the refrigerator.
