Is it necessary to shave off pubic hair for head lice?

Patient's question:

Did I really need to shave off my pubic hair because of pubic lice? Can you give me the best answer? Do topical medications work? Could you guide me more detailedly?
Thank you. First follow-up question: Doctor, hello:
If I shave, is it just local shaving enough? (Or should I shave everything?) What medication did you mention? Is it easily available? I got very nervous after reading this today.

Doctor's answer:

General surgery and treatment require prepping to facilitate cleaning and prevent infection. Pubic hair typically regrows to its original condition within 2 to 3 months. As most people know, pubic lice cause significant harm to patients, so it's important to seek treatment as soon as possible. In daily life, attention should be paid to dietary habits, with a focus on light meals and avoiding irritating foods. Additionally, regular follow-up visits may be necessary when needed.
