Losing hair T^T

I losing my hairs. It began many years ago. I noticed it an year ago. I visited to a clinic and the doctor suggested me to take medicine for lifetime. I didn’t want to take it. Actually I went to the clinic to fix my oily scalp. I searched the clinic online first and the website said oily scalp could be the reason of losing hairs and they have treatments for that. Yet, the unconvincing doctor only gave me medicine that for losing hairs. He added that oily scalp is not the matter and can’t fix. I think he is not a real doctor. He just seemed to want customers who are willing to pay for expensive treatment courses for several months.
My scalp is really oily. I wash my hair two times everyday, in the morning and at night. Even though I wash my hair in the morning, it becomes oily afternoon. It is so annoying. I want to spread soap on my scalp so it doesn’t become oily and also kill some harmlful microbes. I can’t be sure but I think if I can fix my oily scalp, my hair would be thicker. Since I am losing hairs a lot, my hairs are thin. I used to have thick hairs and those were planted strongly in my scalp. I remember that when I was much younger, I grabbed my hairs and pull out but my hair stayed strong. One of my highschool teachers did that to students to wake them up but still my hair was strong enough to endure. Now, aww, they look so weak. What should I do?

Looking at my thin hairs, I think of very thick hair. What if our hair is really really thick so it becomes one hair(?) Cutting hair would be like sculpting. I think it can offer us various styles. Also it will be easy to wash and doesn’t caer of scalp. Ah, I want my thick hair back!!
