A better view on my hairline. Will I need a transplant or will finasteride thicken and regrow hair? (Photo)

Hi Joshyh27, this is a great question . Much like what is stated below as we get older things change and mature. However, if you do have a family history of hair loss and notice your hair line pushing back it will be normal to be alarmed.
It would be best to discuss this with a physician who specializes in hair loss. Finasteride is great in decreasing DHT production and shows improvement mostly in the middle to crown area.
We recommend a layered approach to therapy for our clients and this may be helpful to you as well. Rogaine, vitamins and finasteride in combination can help in preventing further hairless and decrease progression.
Having a strong medical therapy regimen in place prior to any surgical procedure will not only help you now but for the future as well.

Stay well,

To better answer you, we should know your age. Assuming you are in your late 20's or early 30's, I would recommend Finasteride, especially if you feel your hairline has worsened in the past two years. This is not a receding hairline as the first answer claims, there is miniaturization of the frontal line and frontotemporal area, therefore there is evidence of Androgenetic Alopecia. You should work on slowing it down if your family history suggests a much larger pattern in the future (Norwood 4+). Bottom line is that Finasteride will help improve all your hair (including the hairline somehow). Keep in mind that you will need a hair transplant at some stage. Also you better be seen live by a specialized doctor for a full assessment.

You are showing fronto-temporal recession which is androgenetic alopecia (male pattern baldness (MPB)). I do not agree with the first answer.  MPB is an aging process every human gets and it gets worse as you age. Your genetics dictates the severity of MPB.  Tooth decay is an aging process every human also gets.  Fluourinated tooth paste slows tooth decay, not a dentist. A dentist just fills in cavities.  As a hair transplant surgeon I do not stop androgenetic alopecia, finasteride does, I just fill in cavities (ie.- take good genetic hair from the sides/back and transfer it to the balding area).  A hair transplant can eventually look quite unnatural if the doctor does not consider the progressive nature of MPB in each and every individual patient.  Therefore the most conservative route is to start on finasteride (a preventative treatment).  Look at finasteride as similar to tooth paste.  Both are preventative treatments for aging process- 1) the sooner you start the better 2) they are not perfect but they do slow down the aging process, and 3) if you stop the medication you will go back to your genetic predisposition.
The "hair count" studies in the fronal forelock on finasteride at 2 years showed 1)  95% of the patients were doing just as good or better than when they started, 2) 4% had moderate improvement, and 3) 38% had slight improvement.
