  • Mature hairline is the natural phenomenon which is common across teenagers.

Mature Hairline: Causes, detection and prevention

The process usually takes place during a man’s late teens and late twenties, typically between the ages of 17 and 29.

In saying that, the specific age in which a hairline starts to mature differs from man to man. So much so, that some guys can begin showing signs of a maturing hairline before or even after the standard age range.

Hairline maturation is a natural experience that almost all guys will undergo in some way, shape, or form.

Only a small percentage of men retain what is known as their “juvenile hairline”, i.e. the low hairline that boys have. Your hairline matures, just like you do as an individual. This happens as you grow into your adult male body.

Duration of Mature Hairline

The course of developing a mature hairline varies greatly from case to case. Some men can even experience their hairline maturing throughout an entire decade. Others will see the development come to a close within a couple of years. The bottom line is that it won’t happen overnight.

As far as expected ages go, we’ve already clarified that hairlines can start maturing as early as 17 or even earlier, in some cases. It’s quite a unique process for every individual, so welcome it with open arms if it arrives.

Causes of Mature Hairline

A maturing hairline is not just a random fluke of nature. Specific hormonal reactions take place to change the way your hair develops and grows.

Specifically, dihydrotestosterone, or DHT, is the primary hormone that is responsible for your hair recession and male pattern baldness. DHT is a sex steroid or androgen hormone. It’s more powerful than the more well-known regular testosterone. But some DHT is necessary for a healthy male body.

As an androgen hormone, DHT is partially responsible for the biological characteristics that make your body masculine. DHT plays a role in the development of a deeper voice, as well as increased body hair and muscle mass. Unsurprisingly, your body gets saturated with DHT during puberty. This is why your body hair and other sexual characteristics change rapidly in your teenage years.

It’s also why children don’t usually go bald. One of the leading causes of male pattern baldness is an overabundance of DHT, which is almost impossible to experience as a child.

DHT is more powerful than testosterone because it attaches to the same hormonal receptor sites as regular testosterone. But it lasts for much longer and its effects linger far beyond what you would expect from regular testosterone.

Higher than normal levels of DHT slowly miniaturize the hair follicles with time and causes the loss of hair permanently. The receding hairline typically shows a horseshoe shaped pattern in men and a bald patch on crown for women.

This shape is also linked to the abnormally increased secretion and accumulation of DHT at the areas more prone to the hair loss, making a horseshoe pattern. This is linked with chronic scalp tension in people who develop this shape of hairline.

Chronic scalp tension is transmitted to and detected in galea appunurotica. From here a signal goes to the androgenic tissues which are prone to alopecia. These tissues then get inflamed and the hair loss begins. DHT is not directly responsible for the miniaturization of the hair follicles but risk factors like chronic scalp tension add to the inflammation and loss of hair follicles.

Increased amount of DHT however, does contribute to the thinning of hair and weaker hair follicles. This leads to an eventual hair loss by the process mentioned above.

Anabolic steroid drugs may also cause hair loss and baldness down the lane. These drugs are known to cause an increase in the levels of androgens in the body and therefore increased hair loss.



Mature hairline

  • Maturing hairlines can be quite similar to the receding hairlines if the person is not well aware in identifying the difference between the two. Maturation of the hairline continues to a certain time in life. It may start in teen years but it is a long process and ends in a decade, plus minus a year or two.
  • If the hair loss is persistent and does not curb, the hairline might have crossed over to receding from the mere process of maturation.
  • Mature hairline often does not exceed past the anterior borders of the ears on both sides. The hairline from the margins of juvenile hairlines does go back but it stops mostly at a distance of one finger from the first crease on the forehead.


Receding hairline

  • For receding hairlines, there is a high chance that the hair loss is irregular and fast. The hairline that remains might have a horseshoe pattern on the temples showing a higher rate of hair loss in those areas.
  • The hair that the follicles do manage to produce are thin and not durable at all. These hairs fall off easily and at a higher rate than they grow, thereby producing bald spots.
  • For the detection of receding hairline, observe irregular bald spots along other areas of the head as well as the hairline. This confirms that the recession is not just due to maturation of the hairline.

Maturing of the hairline is a natural phenomenon that happens to 96 % of the men as they hit puberty. It happens because of a normal shift in the concentrations of hormones in the body and is coupled with the development of secondary sex characteristics.

The hairline does go back a little when matured as compared to the juvenile hairline, but that does not necessarily signify that the individual is going to get bald in the near future.

For most men, maturation of hairline is so subtle that they don’t even notice as it happens. However, if there is a possible baldness, it is easily noticeable as the loss of hair exceeds the new hair growth and there are evident bald spots.

Hamilton-Norwood scale is one way to determine whether the pattern of hair loss lingers towards baldness or simple maturation. For the stages 1 and 2, the hairlines are most likely to be mere mature and not balding at all.


Detection of Mature Hairline

For normal maturation of the hairline, it happens for a long period of time, years. So, it might go undetected or the difference might hit at once if you observe it.

This maturation might also feel like the hair in front of your forehead are receding as the hairline would be further away as compared to the juvenile hairline. This could be a cause of concern.

However, there is a very simple way to measure the whether the hairline is maturing or receding.

  • Raise your eyebrows like when you are surprised
  • Hold a mirror to your face and observe
  • Put a finger between the top most line on your forehead and the hairline
  • If the distance between the two is greater than one finger, there is a chance that your hair is not just maturing, it might even be receding.


Mature hairline is generally experienced by male. This growth differs as per age and mainly depends on the hormonal activities in the individual. This is the natural and therefore cannot be avoided but in can be reduced by doing some treatments. Hair loss treatment can also be applied as a supplement to proper treatment.
