Hair Regrowth. And left hairline photos!

2 years before my hair was health and at the best condition i can ever imagine, the we're fluffy as well as shiny , I just use oil at that time for styling my hair , but at the age of 16 I started using hair styling products like hair wax and hair spray to get the hold due to which I started facing hair loss , at that time  my most of the hairloss I faced was from the right side of the hairline and after sometime I lost my half of the straight hairline , after this I stopped using any hair styling product and started using natural and herbal oils for healthy hair growth , I also started having good and nutritionist food from then , I also started maintaining good lifestyle  , because of which my hairfall get stopped but the hairs that I lost because of the use of hairstyling products are not growing back my hair line is lost now , I'm confused what have I done  wrong or what is left now that I can do to regrow my hairline. Pls help doc. I've attached my right and left hairline photos
