What are nits and how can we detect them effectively?
Nits are the eggs of head lice, external parasites that feed on human blood. Very small and oval in shape, they are often mistaken for dandruff due to their whitish or yellowish appearance. However, unlike dandruff, nits are firmly attached to the hair near the scalp and cannot be easily removed by shaking the head or brushing the hair.
To detect nits, we recommend using a fine-toothed comb in a well-lit environment, ideally under direct sunlight or strong lighting. Carefully examine the hair strand by strand, paying particular attention to the areas around the ears and at the nape of the neck, where nits are generally more abundant.
What are the most effective methods for removing nits?
Removing nits requires patience and precision. Here are the key steps to follow:
How to prevent an infestation of nits?
Preventing nits is crucial to avoid their spread. Preventive measures include
How to distinguish between nits and dandruff?
Distinguishing between nits and dandruff is crucial to effective treatment. Nits are lice eggs firmly attached to the hair, usually near the scalp. They are oval-shaped and yellowish or brown in color. Unlike nits, dandruff is a flake of dry skin that comes off easily and is usually white or transparent. To check, try moving the object with your fingers: if it doesn't move easily, it's probably a nit.
How long do nits and lice live on a human host?
Nits have a lifespan of 7 to 10 days before hatching into nymphs, which become adult lice after about seven days. Adult lice can live for up to 30 days on a human host. Without human food, they generally die within 24 to 48 hours, limiting their ability to infest new hosts after falling from the head.
Can nits spread through personal objects?
Yes, although the most common mode of transmission of nits and lice is direct head-to-head contact, they can occasionally be spread through personal objects. Sharing hairbrushes, hats, scarves or even pillowcases can facilitate transmission. We recommend washing these objects at a high temperature or placing them in a sealed bag for at least 48 hours to kill the lice and nits.
Are there any preventive treatments against nits and lice?
Preventive treatments against nits and lice include the use of specific repellent products. These products often contain natural ingredients such as tea tree or lavender oil, known for their repellent action. Applying these products can be useful, especially in environments where infestations are frequent, such as schools. However, their effectiveness can vary, and they must be used as directed to avoid overuse or allergic reactions.
How to treat the environment in the event of nit infestation?
In the event of anit infestation, treating the environment is essential to prevent re-infestation. Wash all textiles (sheets, clothes, towels) likely to have been in contact with lice at a temperature of at least 60°C. Vacuum furniture and carpets to remove any nits that may have fallen off. Specific sprays can also be used on furniture or in the car, but always follow the instructions scrupulously to ensure safe and effective treatment.
