While a mature hairline may look similar to male pattern baldness, there are key differences between the two. Before we delve into comparisons, let’s define each condition.


Most men aren’t aware that their frontal hairline may change in thickness between their late teens and late twenties. This process is called a “maturation” of the hairline. Young boys and adolescents typically have a lower hairline than older men. This is most noticeable as the forehead space between the eyebrows and hairline grows wider. The rate and duration of change varies by person. Some may complete the process in five years while others may experience a slow change that lasts decades. It’s also important to note that while most men undergo this change, some never do.

Hairlines come in a variety of shapes depending on facial and cranial structure. “Regular” hairlines are symmetrical with smooth contours, while “irregular” ones appear sloped, jagged, or asymmetrical. Some men may grow into an M-like widow’s peak, characterized by a point or tip in the center of the forehead. Again, individual differences can cause widow’s peaks to vary from subtle arcs to sharp curves.

Male Pattern Baldness

Male pattern baldness is a genetic condition regulated by male hormones. How does this occur? The pores through which hairs emerge, called follicles, shrink in diameter as men age, causing thinning. At some point, the follicles cease to grow new strands, resulting a farther back hairline.

 During the receding process, the hairline moves back from the crown forms into a widow’s peak. As time passes, hair begins to recede from the temple and eventually forms a horseshoe shape.

Differences between a Maturing Hairline and Male Pattern Baldness

Maturation of the hairline does not indicate male pattern baldness. Like greying, it is a normal and harmless part of aging. Here are some key differences between the two conditions:

  • Hairlines retain their shape (regular, irregular, peaked) throughout the maturation process. Slight thinning is usually the only difference.

  • In male pattern baldness, the hairline usually changes shape. For example, a teenager with a widow’s peak may experience thinning such that the peak disappears and the hairline recedes considerably.

  • Men can match the position of their juvenile hairline to their highest forehead wrinkle. A mature hairline is at most 1 to 1.5 centimeters above this point. Men with male pattern baldness will experience recession past this point and additional receding around the temples.

Revivogen can help preserve a more youthful hairline. Continued use helps prevent further recession of the hairline and maintaining the hair your currently have. Read more about the science of hair loss and how the Revivogen 3-step routine can decrease shedding and increase growth.
