How to make my forehead straighter? (Photos)

I  would advise against using implants or fillers for this issue. This is something that only you notice. If you have a problem then it will look abnormal and others will notice. The only thing that you should consider is a hairline advancement which will shorten the slant and make it less obvious. This is done with the Irregular Trichophytic incision so no scar is seen. 

The culprit is either a high hairline, genetically rounded forehead, or bone loss.

Depending on which it is (determined by facial analysis) the treatment will be different.

For the first one we can lower the hairline with a forehead lift. The latter two can be corrected with filler or even better with fat grafting.

Hope this helps.

Best of luck,

Decreasing the slant of your upper forehead is best done by the application of either bone cements or a custom implant for a permanent and assured solution. This is done through a more posterior scalp incision or one right along the frontal hairline.

It is difficult to determine facial proportions with this picture but I suspect a better result can be achieved by lowering your hairline using the Irregular Trichophytic Hairline Incision Technique that we described many years ago rather than changing the contour of your forehead.

The problem with a situation like this is that you may make an issue which only you see into an issue that everyone see.  You could fill in the area with HA fillers, which would be expected to last up top 4 years in a non mobile area like the forehead.  Distribution is difficult here, but at least you have the ability to remove the filler if necessary. methyl methacrylate or a custom implant in an open procedure could change the skull shape as well.  YOu could also grow you hair longer and comb it forward.
