How to tell the difference between nits and dandruff

When it comes to an itchy scalp, there are a few common culprits that often come to mind, such as nits and dandruff. These unwelcome visitors can cause discomfort and annoyance, but telling them apart is crucial for effective treatment.

Nit Eggs_ Nits are tiny parasites that infest the scalp and feed on blood. To continue their life cycle, they lay eggs, near the base of the hair shafts. These eggs are incredibly small, about the size of a pinhead, and have a characteristic oval shape.

Adhesive Nature_ Unlike dandruff, which can be easily brushed off, nit eggs firmly attach themselves to individual hair strands. This attachment is facilitated by a sticky substance secreted by the female louse. It is this adhesive quality that makes nits difficult to remove without specialised tools.
Close to the Scalp_ Another distinct feature of nit eggs is their proximity to the scalp. They are usually laid within 6mm of the scalp to provide the ideal temperature and humidity for incubation. This is why thorough inspection of the hair roots is crucial when checking for the presence of nits or their eggs.

Dandruff: Dandruff, on the other hand, is a common scalp condition caused by the excessive shedding of dead skin cells. It is often characterized by dry, flaky skin that can be mistaken for nit eggs if not examined closely. However, there are some key differences that set dandruff apart.

Mobility: Unlike the static nature of nit eggs, dandruff flakes tend to move. They can easily fall from the scalp and onto clothing or shoulders, which is a common occurrence when brushing or shaking the hair. This ability to move distinguishes dandruff from nits, which remain firmly attached until removed manually.
Scalp Irritation_ While nit eggs do not cause direct scalp irritation, dandruff often leads to itchiness and inflammation. This itching sensation can vary in intensity and is usually accompanied by redness or a dry, tight feeling. It's important to note that excessive scratching may exacerbate dandruff symptoms and lead to secondary infections.

Conclusion: Although head lice eggs and dandruff can both cause itching and discomfort, understanding their differences is essential for appropriate treatment. ISpy Nit Detector® glow powder illuminates the eggs not the dandruff allowing you to easily spot and remove eggs before they hatch.

Remember, head lice eggs stick to the hair shafts and are difficult to remove, while dandruff moves and can easily be dislodged.
