What can I do to shrink my forehead? (Photo)

Unless you are considering cosmetic surgery such as forehead reduction or hair transplant surgery, you cannot "shrink" your forehead. 

Your forehead does not look prominent based on your photograph.Even the area by your eyebrows looks aesthetically sound, however, the upper nose(radix) is depressed(sunken)and that may be what you are noticing.When this occurs it can make the forehead look more prominent. This occurs as we loose facial bone as part of the aging process.Fat grafting or fillers are your best option.Hope this helps

Men normally develop a mature hairline losing their juvenile hairline that is the hallmark of childrens' hairlines. A hair transplant can be done to move the hairline down, but you need to see a doctor who is familiar with the hairlines in men. I wrote a classic medical journal article about hairlines in men, women and children. If you send me some photos, I can give you more of an opinion. I need to know your age.
