Purpose of Use: It kills lice by blocking their respiratory tract and suffocating them. How to Use: *Cover shoulders with a towel. *Apply BIONYT Spray in sufficient amount to your dry hair from a distance of 10 cm and equally to each area. Make sure that it contacts every part of your hair and scalp. *Be careful not to let the spray come into contact with your eyes and face, and be careful not to inhale the spray. *After 30 minutes, comb your hair with the metal-toothed fine lice comb that comes in the box. *After applying the mixture, wait for your hair to dry for 6-8 hours. (Do not use a hair dryer.) *After washing your dried hair with your normal hair shampoo, rinse with plenty of water. *It is very important to reuse BIONYT Spray within 7 days, which is the formation period of the nits. If reapplication is not made after 7 days, the hair may get lice again during the ovulation period. WARNINGS: If any side effects occur, discontinue use and rinse with plenty of water.
