I said until they die, check the research and statistics available, it's actually 5% i was wrong
"About 5% of Caucasian men will keep their juvenile hairline their entire lives.
Most men won’t keep their young hairline, though. Instead, usually between the ages 17 and 30, most men will develop a mature hairline, a sign of getting older. A mature hairline occurs when the hairline moves back about a half inch to one inch from where it used to be. That’s all it is. A mature hairline is a completely natural occurrence for most men and not something to worry about.
Characteristics of maturing hairlines
Not all hairlines mature the same, just as all men don’t mature the same. Mature hairlines can occur gradually — to the point that it’s not even noticeable. Some men find it takes 10 years for their hairline to fully mature. On the other hand, some men might find their hairline receding more rapidly, and that’s why some worry it might be male-pattern baldness. Rapid recession can be a sign of a receding hairline, too. Luckily, there are some other characteristics of mature hairlines that set them apart from male-pattern baldness.
- The hairline usually moves back evenly. Though some men will experience an uneven transition to a mature hairline, most will find their hairline moves evenly over time.
- The hairline is only about one to 1.5 inches above your highest wrinkle. This is typically as far as a mature hairline will recede. If your hairline is about the width of your finger above the top wrinkle, you probably have a mature hairline. If it’s receding onto your scalp, it may mean balding.
- The shape is an M or a widow’s peak. An M-shaped hairline removes the round curves of the young hairline and makes a more defined hairline. Frequently, the hairline might create a widow’s peak. A widow’s peak is when there is a V of hair that remains farther down while the hair alongside it recedes more.
Maturing hairline vs. receding hairline
Maturing hairlines and receding hairlines—usually caused by male-pattern baldness—can often start very similarly, so it can be difficult to tell which is causing your hair loss. There are some things that set them apart that can be useful in identifying if your hairline is receding.
- Excessive hair shedding. While there is some hair loss with a maturing hairline, a receding hairline will have clumps of hair coming out, usually when showering or styling. It’s normal to lose 100 hairs a day, but if you’re losing more than that, you may be starting to bald.
- Extra recession on your temples. While a mature hairline does form an M, it’s usually not extremely pronounced. Even if your entire hairline is moving back, if you notice the areas around your temples moving even more, it may be a sign of balding.
- Small hairs beyond your hairline. While everyone has some smaller hairs in front of their hairline, a large amount of light, short hairs in front could mean you’re balding.
If you’re still unsure if your receding hairline is balding or maturing, or if you have other questions, you can check with a doctor. Doctors are able to view the hairs under a microscope to see what is
causing your hairline to recede. They’ll also be able to tell if your receding hairline is male pattern baldness."
