Painful lice combing schedule for a man

I am a 28 years old male living in vikhroli mumbai. I live alone here since last 4 years and my family is in my native.i keep long hairs upto my waist and normally tie it in a pony or a plait or some time in a bun. 

Since last 1 month i have been suffering with lice infection in my hair. As a stay alone i have no one to take care of it . So i discussed this with my neighbour's daughter who is very close to me. She initially laughed at me, but then told me she will come next day afternoon. I wondered what she was going to do. Next day she came in the afternoon and showed me the lice comb she had bought for me. She asked me to bring coconut oil bottle and sit facing my back to her. 

She Opened my plait and started searching for nits in hair by moving her fingers in my hair. After some time she oiled my hair heavily and started combing my hairs with lice come. She found many and handed over to me for killing. This continued for about 1 hour until no more lice were found in lice comb. Then she tied my hair in bun and asked me to clean my clothes and keep the comb. 

She told she will repeat this after 2 or 3 days so as to get rid of lice. I thanked her. I immediately felt a huge relief by itching scalp. after another 2 sessions i got much relief. Atlast i thought i was free from lice. 

But again yesterday night i felt lot of itching and so went to her home to ask for lice combing. Her mother (my neighbouring aunt) opened the door and told me she had gone to some relatives place for 2 days. She also told me that her daughter had discussed my lice issue to her and she can do tomorrow morning for me if i don't mind. I smiled and she asked me to bring my lice comb and come to her house. 

Today even being sunday i woke early and had bath took the lice comb and went to her place,. She also followed the same routine as her daughter did but oiled my hair more heavily. Just finished 2 hour of lice combing from her. She had asked me not to wash my hair and come in afternoon when she and her 2 maids will make me sit in our common balcony or terrace and do harsh and painful lice combing. Also asked me to buy 3 lice comb and bottle of castor oil which she will mix with coconut oil and apply in my hair before lice combing, just purchased lice combs and castor oil.
