Understanding Hair Lice And Nits
Hair lice are parasitic insects that live on the scalp and feed on human blood. While not dangerous, lice cause significant discomfort and can spread rapidly, especially among children.
How Do Hair Lice Spread?
Hair lice are highly contagious and spread through direct and indirect contact.
Modes of Transmission
- Head-to-head contact – The most common way lice spread, especially among children.
- Sharing personal items – Combs, hats, hair accessories, and pillows can carry lice.
- Crowded environments – Schools, daycare centers, and playgrounds increase transmission risk.
Risk Factors
- Children aged 3-11 are at the highest risk due to frequent close contact.
- Household members of an infected individual are more likely to contract lice.
- Poor hygiene is NOT a cause – Lice infests anyone, regardless of cleanliness.
Dr Batra’s® pro tip:
Dandruff isn’t just a scalp issue—it affects confidence, focus, and emotional well-being, especially in children. Constant itching can cause discomfort, lack of concentration in studies, and low self-esteem in social settings. Homeopathy offers a gentle, long-term solution by treating the root cause, ensuring a healthy scalp and a confident mind. – Dr. Akshay Batra
