You may not notice it at first—a stray hair on your pillow, a widening part in the mirror—but hair loss often starts quietly, sneaking up until one day the difference is undeniable. For both men and women, it is common yet frequently unexpected and can seem difficult to understand. What many perceive as a sudden circumstance is usually a slow process driven by genetics and hormonal shifts. Taking a closer look at what causes hair loss can help bring clarity to this often out-of-control change.
Hair loss is not as random as it may seem. According to Dr. Brad Logan of Ixchel Skin & Body, the most significant factor is something many people cannot control. “The most common cause for both men and women is actually genetic,” shared Dr. Logan. As the body changes over time, so do the hormones that influence hair growth. “We are pre-programmed, unfortunately, to produce hormones that increase as we age, and they lead to hair loss,” he explained. That process can begin earlier than many expect and continues gradually over time.
While it is often one of the first explanations people reach for, stress is not typically the driving force behind genetic hair loss. “We like to joke that our kids stress us out and make us lose our hair. That’s just part of the genetic hair loss that we’ve got going on,” said Dr. Logan.
Other factors can also influence how hair loss progresses over time. “The reality is a poor diet may accelerate hair loss,” noted Dr. Logan. While genetics may set the foundation, lifestyle habits can still play a role in how quickly those changes become noticeable.
While the cause may be similar, the way hair loss appears can look very different from one individual to another. “With men, they tend to start to lose hair over the temples, and then the hair starts to recede back,” said Dr. Logan. Over time, that recession may become more pronounced, sometimes extending toward the back of the head. For women, the change is often less obvious at first. “They tend to lose their hair centrally, meaning down the center of their head, and it usually happens on a strip one to two inches wide,” he explained. Instead of full loss, many women notice thinning that changes the overall look and volume of their hair.
One of the challenges with hair loss is how late it becomes noticeable. “A person typically won’t notice hair loss until thirty percent of the hair in an area is lost,” shared Dr. Logan. By the time it is visible, the process has already been underway for some time. Early signs are often mistaken for less significant matters. “They don’t seem to have the volume of hair,” he explained, describing what many patients notice first.
When people begin to notice changes, the instinct is often to look for quick solutions. However, not all options are equally effective. “The biggest misconception is that they can use some over-the-counter products and some well-marketed products that are available over the internet that may produce minimal increases in hair growth or minimal prevention of hair loss, but for the amount of money that’s expended on them, the gain is not great,” said Dr. Logan. Instead, a more informed approach can help clarify which options are worth pursuing.
Early intervention can make a meaningful difference in the progression of hair loss. “The most important things that people can do when they start losing their hair is to use true medical hair treatments,” explained Dr. Logan. Supporting the follicle at its source can help preserve existing hair.
For those experiencing more advanced hair loss requiring transplantation, modern techniques have advanced immensely in recent years. “What we do now is we do what’s called follicle unit extraction,” shared Dr. Logan. This approach allows individual hair follicles to be transplanted, creating a completely natural look that blends seamlessly with existing hair.
The transplantation process itself is often more gradual than people expect. “Within a couple of days, a transplanted hair follicle begins to settle well into your scalp, and within a week, it’s not coming out of there,” explained Dr. Logan. While visible hair may shed after the procedure, this does not mean the process has failed. “They go to sleep for a while,” he said, referring to the follicles before new growth begins. “In four to six months, you’ll see nice hair starting to grow back, and by the time that year ends, you’ll have that full hair that you were looking for,” he added.
Hair loss can feel deeply personal, but it is also widely shared. What matters most is not just understanding why it happens, but recognizing that there are ways to respond to it. As research and treatments continue to evolve, so do the options available to those experiencing change. What may begin as a moment of concern can become an opportunity to better understand your body and take a more informed, confident approach to maintaining your hair over time.
