How do you know if lice is underneath your scalp?

To determine if lice are present on your scalp, look for symptoms such as persistent itching, which is often caused by an allergic reaction to lice bites. You may also notice small white or yellowish eggs (nits) attached to the hair shafts close to the scalp. Additionally, you can check for adult lice by parting your hair in sections and examining the scalp and hair closely, particularly behind the ears and at the nape of the neck. If you suspect an infestation, it's best to consult a healthcare professional for confirmation and treatment options.
