Can you describe exactly what you found or upload a photo?

Since I can’t see the object or the insect right now, here are the most common causes of unusual findings in children’s hair, as well as information on when to see a doctor:

3 most common causes

Head lice or nits (lice eggs)

Appearance: Nits are tiny, oval, whitish-gray or brownish pellets. Adult lice are 2–3 mm long, wingless, and brownish.

Typical characteristics: Nits are firmly attached to the base of the hair (usually behind the ears or at the nape of the neck) and, unlike dandruff, cannot be easily blown out or brushed out.

Dandruff or hairspray/gel residue

Appearance: White, flat flakes.
… Typical characteristics: Loosely lying on the scalp or in the hair and can be easily combed or blown off.

Ticks
Appearance: Small, dark brown to black arachnids (8 legs) that are firmly anchored in the scalp and can become quite swollen over time.

When should you see a doctor?
A visit to the doctor is essential:
If it is a tick that you cannot completely remove yourself, or if redness (erythema migrans), fever or headache occurs after removal.

If the scalp is severely inflamed, scratched, chafed or pus is oozing.

If you are unsure and need a prescription for lice treatment (health insurance companies usually reimburse the cost of approved lice treatments for children).

A visit to the doctor is not necessary (self-treatment is possible):
If it is lice/nits and the scalp is intact. A special lice shampoo or liquid (e.g. dimethicone-based) from a pharmacy will help, along with a fine-toothed nit comb.

Would you like to describe the lice in more detail (size, color, whether they are attached or crawling) so that I can help you more effectively?
