Does lice make your hair thin?

Lice themselves do not directly cause hair thinning; they feed on blood from the scalp and can lead to itching and irritation. However, excessive scratching due to itching can damage hair follicles and potentially result in hair breakage or thinning. Additionally, if lice infestations are untreated for prolonged periods, secondary infections may occur, which could also affect hair health. Overall, while lice don't directly thin hair, the associated effects can lead to hair loss.
