Hi, I am 19 years old and have a thick head of hair. There is no thinning present whatsoever. However, when i pull my hair back to look at my hairline, i notice that it goes in diagonally, not quite at 45 degrees but still noticeable diagonally (perhaps the mirror exaggerates how diagonal it is), the right side more so than the left as well. I have shown my mum, grandma and sister, and they have said that my hairline is normal and not receding. I know its hard to tell without seeing it, but are they right and is this type of hairline normal or is it a receding hairline. Like I said, when my hair is not pulled back, I have a thick head of hair and you would not notice that I had this type of hairline.
This clearly bothers you. I suspect that there is some maturing of your hairline at 19, which is common in men. You could send me pictures with your eyebrows lifted high (a good digital photograph) and I will give you an opinion. Please reference this blog posting when/if you send photos. Thanks.
