Hair loss on sides of my head. Shampoo.

I'm 20yr old boy, I have a hair loss on sides of head. So I tried to cured it from a natural way by applying coldpressed castor oil on hair. I didn't observe any major changes. So I tried to go for a shaving my head and then applying castor + almond oil on hair. I mostly kept this for overnight. On morning, I just wash it once with shampoo.But I think that oil didn't get removed from my head. Due to which, the oil was there on my head for 2-3 days. And I applied castor oil for 2 times in a week.So you can say that oil was on my head for a week. I continued above process about a month. Now when I started growing hairs on my head(after shaving head). I begin to notice tiny bald spots on front view of my head. It looks like a hair are not coming properly as were present before. So I'm confused wheather to continue this process or not. Means, I should apply castor + almond oil on hair and this time I make sure that the oil should be removed completely by conditioner and shampoo.
