Does Shaving Really Make Your Hair Grow Back Thicker ?

For many young men, the idea that shaving can make your hair grow back thicker and fuller is a persistent myth. As you prepare for an important formal event, you may be tempted to start aggressively shaving in hopes of cultivating a more mature, masculine look. But does this strategy actually work? Or are you just setting yourself up for disappointment and irritated skin?

In this in-depth article, we’ll take a close look at the science behind hair growth and shaving to uncover the truth. We’ll examine multiple studies that have been conducted over the past century to see if there’s any validity to the claim that shaving leads to thicker hair regrowth. By the end, you’ll have a clear understanding of what really happens when you pick up that razor.

The Life Cycle of Hair

To understand the relationship between shaving and hair growth, we first need to examine the natural life cycle of human hair. On average, hair grows at a rate of about 1.3 cm per month. However, this growth rate can vary depending on factors like:

• Season – Hair tends to grow faster during warmer months like summer compared to colder months like winter.
• Genetics – Some people are simply predisposed to having faster or slower hair growth.
• Age – Hair growth often slows down as we get older.

The hair growth cycle consists of three main phases:

1. Anagen Phase: This is the active growth phase, where the hair follicle is healthy and the hair is actively growing. This phase can last anywhere from 2 to 6 years.
2. Catagen Phase: During this transitional phase, the hair stops growing and becomes detached from the blood supply at the root. This phase lasts around 2-3 weeks.
3. Telogen Phase: This is the resting phase, where the hair follicle is dormant and the hair will eventually fall out. This phase lasts about 3-4 months.

As men age, they tend to experience more and more hairs entering the dormant telogen phase, leading to increased hair loss and balding. But does shaving have any impact on this natural cycle?

The Science on Shaving and Hair Growth

The idea that shaving can stimulate thicker hair growth has been around for decades. In fact, there have been numerous scientific studies conducted over the years to investigate this claim.

One of the earliest studies was done in 1928 by researcher Mildred Trotter. She conducted a long-term study on a small group of men, focusing on the hair growth on their cheeks just below the ears. Trotter carefully controlled factors like the razors used, the shaving soap, and even the water temperature to ensure consistency.

The results of Trotter’s study were clear – shaving had no effect on the thickness or length of the regrown hair. The longer the hair was allowed to grow, the more it grew, but this was simply due to the natural hair growth cycle, not any stimulation from shaving.

A later study in the 1970s took a different approach, this time focusing on the hairs on the front of the leg between the knee and ankle. This area was chosen because it has a high proportion of dormant hairs compared to actively growing ones, making it easier to detect any changes in new hair growth after shaving.

The researchers had the men shave a 10×10 cm square on one leg, but not the other. Over several months, they regularly shaved the same spot on one leg and then compared the new hair growth to the unshaved leg. Once again, the results showed no significant difference in the thickness or width of the newly grown hairs.

These studies, along with numerous others using both human and animal subjects, have all come to the same conclusion – shaving does not cause hair to grow back thicker or faster. So why does it sometimes seem like that’s the case?

The Optical Illusion of Thicker Hair

If shaving doesn’t actually make hair grow back thicker, why do so many people believe that it does? The answer lies in an optical illusion created by the way hair grows.

When you shave, you’re removing the top, dead portion of the hair shaft. This part of the hair is typically narrower and lighter in color than the hair root that’s still embedded in the follicle. The hair root, which is still being nourished, is usually a more vibrant color.

Additionally, the blunt, freshly-cut ends of shaved hair can make it appear thicker than the naturally tapered ends of unshaved hair. And if the hair you’re shaving off has been exposed to the sun or chemicals, it may be slightly bleached or faded, further enhancing the contrast with the unshaved root.

So while the new hair growth isn’t actually any thicker, the visual contrast can create the illusion that it is. This optical effect is likely what has perpetuated the myth of shaving leading to thicker hair.

Debunking Other Shaving Myths

In addition to the claim that shaving makes hair grow back thicker, there are a few other common myths about shaving that are worth addressing:

Myth: Shaving Makes Hair Grow Back Faster

Similar to the thickness myth, the idea that shaving causes hair to grow back faster is also not supported by scientific evidence. The rate of hair growth is determined by the natural hair growth cycle, not by shaving.

Myth: Shaving Makes Hair Coarser

Again, studies have shown that shaving does not affect the actual thickness or coarseness of the hair. The blunt, freshly-cut ends may feel a bit rougher, but the underlying hair structure remains the same.

Myth: Shaving Causes Ingrown Hairs

Ingrown hairs are caused by a variety of factors, including curly hair texture, improper shaving technique, and skin irritation. While shaving can potentially contribute to ingrown hairs in some cases, it is not the sole cause.

Myth: Shaving Leads to Increased Hair Growth

Some people believe that shaving stimulates the hair follicles, causing more hair to grow in over time. However, this is not the case. Shaving only removes the visible portion of the hair, it does not impact the underlying follicles or increase the total number of hairs.

So in summary, while shaving may create some temporary visual effects, it does not actually alter the fundamental properties or growth patterns of your hair. The thickness, coarseness, and rate of growth are all determined by your individual genetics and biology.

Tips for Healthier, Thicker-Looking Hair

If you’re looking to achieve a fuller, more masculine appearance, there are some more effective strategies than just shaving:

• Embrace Your Natural Growth Cycle: Allow your hair to grow out naturally between trims. This will give the appearance of thicker, more substantial hair.
• Use Volumizing Products: Styling products like thickening shampoos, conditioners, and mousses can help add volume and texture to your hair.
• Consider Supplements: Certain vitamins and minerals, like biotin, can support healthy hair growth when taken as a supplement.
• Improve Your Diet: Eating a nutrient-rich diet with plenty of protein, iron, and other hair-healthy nutrients can nourish your follicles.
• Reduce Stress: Chronic stress can disrupt the hair growth cycle and lead to increased shedding. Try to manage your stress levels through relaxation techniques.

And of course, be patient and let nature take its course. As you get older, your facial and body hair will continue to develop and fill in, even without aggressive shaving.

Conclusion

The belief that shaving makes your hair grow back thicker is a persistent myth that has been thoroughly debunked by scientific research. While shaving can create some temporary visual effects that make new hair growth appear thicker, it does not actually alter the underlying properties or growth patterns of your hair.

The thickness, coarseness, and rate of hair growth are all determined by your individual genetics and biology, not by how often you shave. So if you’re hoping to cultivate a more masculine, hairy appearance for an upcoming formal event, your best bet is to simply let your natural hair growth do its thing.
