One of the thorny problems that make women always headaches and lose sleep is the problem of underarm hair growing under the arms, a very sensitive issue that embarrasses women. Armpit hair will begin to appear when we enter puberty. For men, having armpit hair is a very normal thing. However, it is unfair to women, because it will be a weakness for them, making them self-deprecating, guilty, not daring to wear tops, not daring to show off their bodies, and annoying armpit chin. Moreover, more terrible is that your armpits will be dark and have a bad body odor that makes you alienated from everyone.
This article will help women regain their confidence when they understand why their armpit hair grows so fast and methods to help them remove hair effectively. Improving these issues helps you to love life and be more confident in yourself.

Key Takeaways
- Hormonal influence: The growth of armpit hair is primarily determined by hormonal factors. During puberty, the body undergoes hormonal changes that trigger the growth of hair in various areas, including the armpits. Androgens, particularly testosterone, play a significant role in stimulating hair follicles in the armpits.
- Genetic factors: The rate of armpit hair growth can vary from person to person due to genetic factors. Some individuals may naturally have faster hair growth in their armpits, while others may experience slower growth. These genetic differences can influence the thickness, length, and speed of hair growth.
- Anagen phase duration: The growth cycle of hair consists of three phases: anagen (growth), catagen (transition), and telogen (rest). The length of the anagen phase determines how long hair can grow. Armpit hair has a relatively short anagen phase compared to other body hair, which means it reaches its maximum length more quickly.
- Increased blood flow: The armpit region has a high concentration of blood vessels, leading to increased blood flow. This enhanced circulation supplies essential nutrients and oxygen to the hair follicles, promoting faster hair growth.
- Individual metabolism: Metabolic rate can impact the speed of armpit hair growth. Individuals with a higher metabolic rate tend to have faster hair growth overall, including in the armpit area. Metabolism influences the rate at which cells divide and replicate, including those in the hair follicles.
- Personal grooming habits: Shaving or trimming armpit hair can create an illusion of faster regrowth. When hair is cut or removed, it grows back from the root, which may give the appearance of rapid growth compared to gradual growth from shorter hairs.
- Age and gender: Armpit hair growth can vary depending on age and gender. During puberty, both males and females experience increased hair growth as a result of hormonal changes. However, adult males tend to have thicker and faster-growing armpit hair due to higher testosterone levels.
- Cultural and societal norms: Cultural and societal norms may influence personal grooming practices, including the desire to remove or maintain armpit hair. Some individuals may perceive their armpit hair as growing faster due to regular removal or trimming.
Why Does My Armpit Hair Grow So Fast? – 7 Reasons

Armpit hair, also known as underarm hair, refers to the hair that grows in the armpit or axilla region of the body. It is a natural and common characteristic of human beings, typically found in both males and females after the onset of puberty.
Armpit hair is part of the body’s natural hair growth cycle and serves various purposes. It helps regulate body temperature by assisting in sweat evaporation, acts as a barrier to reduce friction between the arms and torso, and can potentially trap pheromones that play a role in sexual attraction.
Armpit hair can vary in thickness, color, and density among individuals. The growth rate of armpit hair varies as well, influenced by factors such as genetics, hormones, and age. While cultural and personal preferences often dictate grooming practices, individuals have the choice to keep their armpit hair as it naturally grows or remove it through various methods such as shaving, waxing, or trimming. Here are some possible reasons:
Hormonal Changes During Puberty

Hormonal influence plays a significant role in stimulating the growth of armpit hair and determining its rate of growth. The onset of puberty is accompanied by significant hormonal changes in the body. The hypothalamus-pituitary-gonadal axis is activated, leading to an increase in the production of sex hormones like testosterone and estrogen. These hormonal shifts signal the development of secondary sexual characteristics, including the growth of armpit hair.
Androgens, such as testosterone, are hormones that play a crucial role in hair growth, including the growth of armpit hair. During puberty, both males and females experience an increase in androgen levels. Testosterone, in particular, is responsible for stimulating the growth of terminal hair, which is thicker and darker than the fine vellus hair that covers much of the body. Higher levels of testosterone can lead to faster and more robust armpit hair growth.
Genetics

Genetics can also influence the density of hair follicles in the armpit region. People with higher follicle density may experience faster hair growth due to a larger number of actively growing follicles. Hair growth patterns, including the speed of armpit hair growth, can run in families. If your close relatives, such as parents or siblings, have fast-growing armpit hair, there is a higher likelihood that you may also experience similar growth patterns due to shared genetic factors.
Increased Blood Circulation

Increased blood circulation in the armpit area can contribute to faster armpit hair growth. Blood carries essential nutrients and oxygen that are necessary for hair growth. When blood circulation is enhanced in the armpit region, a higher concentration of these nutrients and oxygen is delivered to the hair follicles. This increased supply provides the necessary resources for optimal hair growth, potentially leading to faster growth. Improved blood circulation can stimulate the hair follicles in the armpit area. Hair follicles have a rich blood supply, and when blood circulation is increased, it can enhance the activity and function of the follicles.
Metabolism

Metabolism can influence the speed of armpit hair growth due to its impact on cellular processes and the rate of cell division. Hair growth relies on the continuous division and replication of cells in the hair follicles. Metabolism, specifically the metabolic rate, influences the speed at which cells divide and replicate. A higher metabolic rate can result in faster cell division, including in the hair follicles of the armpit region, leading to faster hair growth.
Metabolism influences the production, breakdown, and balance of these hormones, which in turn affect hair follicle activity. Optimal hormone regulation through a healthy metabolism can contribute to faster armpit hair growth.
Age And Gender

Age and gender can influence the rate of armpit hair growth. Armpit hair growth tends to increase with age, particularly during puberty. During puberty, hormonal changes occur, leading to the development of secondary sexual characteristics, including the growth of armpit hair. As individuals age beyond puberty, the rate of armpit hair growth may stabilize or slightly decrease, as hormonal levels become more balanced.
There are significant gender differences in armpit hair growth patterns. Males typically have higher levels of androgens, particularly testosterone, compared to females. Testosterone plays a crucial role in stimulating hair growth. As a result, males tend to have faster and thicker armpit hair growth compared to females. However, it’s important to note that there can be variations among individuals, and not all males will have faster-growing armpit hair than all females.
Personal Grooming Habits

Personal grooming habits, particularly the practice of shaving or trimming armpit hair, do not directly affect the rate of hair growth. However, these habits can create the perception that armpit hair grows faster. Regularly shaving or trimming armpit hair can give the impression of faster regrowth because you are frequently removing the visible hair. If you maintain a routine of removing hair from the armpits, you may notice the regrowth more frequently, making it seem like the hair is growing faster. However, the actual rate of growth remains unchanged.
Perception Bias

Perception bias refers to the subjective interpretation or evaluation of a situation based on preconceived notions, personal beliefs, or individual experiences. In the context of armpit hair growth, perception bias can influence the perception that armpit hair is growing faster than it actually is. Confirmation bias refers to the tendency to seek out information or experiences that confirm our existing beliefs or expectations. If an individual believes that their armpit hair is growing quickly, they may selectively notice instances that align with this belief while disregarding or downplaying evidence to the contrary.
How Many Methods Of Armpit Hair Removal Are There?

Armpit hair removal is a personal choice, and the benefits can vary from individual to individual. Armpit hair can trap sweat and bacteria, contributing to unpleasant body odor. By removing the hair, there is less surface area for bacteria to cling to, potentially reducing body odor. Removing armpit hair can help reduce the accumulation of sweat, bacteria, and odor in the underarm area. Without hair, it may be easier to keep the armpits clean, leading to improved hygiene.
Some people find that removing armpit hair provides a smoother and more comfortable feeling. It can reduce friction and irritation, particularly during physical activities or when wearing certain clothing. There are several methods of armpit hair removal available. We will now provide you with an overview of how long it typically takes for hair to grow back after removal. Remain engaged for further details.
Method of Armpit Hair Removal | Time for Hair Regrowth |
Shaving | 1-3 days |
Waxing | 2-4 weeks |
Depilatory Creams | 1-2 weeks |
Laser Hair Removal | 6 months |
Electrolysis | Permanent |
Epilation | 2-4 weeks |
Sugaring | 2-4 weeks |
Trimming | Hair is not completely removed |
Shaving

Shaving is a popular method of armpit hair removal. It involves using a razor or electric shaver to cut the hair at the skin’s surface. Shaving is a quick and easily accessible method that can be done at home. Razors and shaving creams or gels are generally affordable and widely available. Shaving is a relatively painless method of hair removal.
However, Shaving only cuts the hair at the surface level, so hair regrowth occurs relatively quickly, typically within a few days. As hair regrows, it can create a stubbly feel and appearance. Shaving can cause skin irritation, razor burn, or ingrown hairs, especially if not done with proper technique or using a dull blade.
Waxing

Waxing is a popular method of armpit hair removal that involves applying hot or cold wax to the armpit area and then quickly removing the wax, along with the hair, in one swift motion. Waxing removes hair from the root, resulting in slower regrowth compared to shaving. Hair typically takes several weeks to regrow. Waxing provides a smoother skin surface as it removes hair from the root, eliminating the stubbly feeling. Waxing can be done at home using waxing kits or by visiting a professional salon.
However, Waxing can cause temporary discomfort or pain during the removal process, particularly in sensitive areas like the armpits. Waxing can lead to redness, inflammation, or skin sensitivity, especially for those with sensitive skin or if done improperly. Professional waxing services can be more expensive than other hair removal methods, and at-home waxing kits require an upfront investment.
Depilatory Creams

Depilatory creams are chemical-based products that dissolve the hair just above the skin’s surface. Depilatory creams work by applying a chemical formulation to the armpit area that breaks down the hair structure, allowing it to be easily wiped or rinsed away. Depilatory creams are easy to use and can be done at home. Hair removal occurs within minutes of applying the cream, providing instant results. Compared to shaving, depilatory creams can result in slower regrowth as the hair is dissolved slightly below the skin’s surface.
However, Some depilatory creams may have a distinct chemical smell that some individuals find unpleasant. Depilatory creams contain chemicals that can cause skin irritation, especially for those with sensitive skin. It’s essential to patch-test a small area before using the cream on a larger area. Hair regrowth occurs relatively quickly after using depilatory creams, typically within one to two weeks.
Laser Hair Removal

Laser hair removal is a long-term method of hair reduction that involves the use of a laser device that emits a concentrated beam of light, targeting the pigment (melanin) in the hair follicles. The heat from the laser damages the follicles, inhibiting future hair growth. Laser hair removal targets the hair follicles, leading to a gradual reduction in hair growth over time. With multiple sessions, some individuals may experience permanent hair reduction. Laser hair removal can treat larger areas relatively quickly, with each pulse of the laser covering a large surface area.
However, Laser hair removal is generally more expensive than other hair removal methods. The total cost depends on factors such as the number of sessions required and the size of the treatment area. Laser hair removal can cause temporary discomfort or a stinging sensation during treatment, particularly in sensitive areas like the armpits.
Electrolysis

Electrolysis is a method of permanent hair removal that involves the use of a fine probe inserted into each hair follicle to deliver electrical currents. The currents damage the follicles, preventing future hair growth. Electrolysis is considered the only FDA-approved method of permanent hair removal. Electrolysis can be used on various skin and hair types, including individuals with light hair or dark skin. Electrolysis targets each hair follicle individually, making it suitable for precise treatment in smaller areas like the armpits.
However, electrolysis is a time-consuming process as each hair follicle needs to be treated individually. The total treatment time depends on the size of the treatment area. Electrolysis can be more expensive compared to other hair removal methods, especially considering the multiple sessions required for complete treatment.
Epilation

Epilation is a method of hair removal that involves using an electrical device called an epilator to remove hair from the root. Epilation removes hair from the root, resulting in slower regrowth compared to shaving. Hair typically takes several weeks to regrow. Epilation can be done at home with an epilator device, offering a convenient option for armpit hair removal. Epilators are a one-time purchase, making them a cost-effective long-term hair removal solution.
However, epilation can cause temporary discomfort or a pinching sensation during the hair removal process, especially in sensitive areas like the armpits. Some individuals may experience redness, inflammation, or skin sensitivity after epilation, especially if they have sensitive skin or if the epilation is done improperly. To maintain hair-free underarms, regular epilation sessions are required as hair regrows.
Sugaring

Sugaring is a natural method of hair removal that involves applying a sticky paste to the armpit area, allowing it to adhere to the hair, and then quickly removing the paste, along with the hair, in the opposite direction of hair growth. Sugaring removes hair from the root, leading to slower regrowth compared to shaving. Hair typically takes several weeks to regrow. Any residual sugaring paste can be easily cleaned up with water, as it is water-soluble.
However, sugaring may require some practice and technique refinement to achieve effective hair removal. Working with the sugaring paste can be a bit messy, and it may require some effort to remove any sticky residue left on the skin.
Trimming

Trimming is a method of armpit hair maintenance that involves using scissors or an electric trimmer specifically designed for hair trimming to shorten the length of the armpit hair. Trimming is a simple and time-efficient method of armpit hair maintenance that can be done at home. Trimming does not involve removing the hair from the root, so it generally causes minimal discomfort.
However, trimming only shortens the hair length without removing it from the root, so the hair regrows at its natural rate. Compared to other hair removal methods, trimming does not provide the same smoothness or closeness to the skin. To maintain the desired hair length, regular trimming sessions are required as the hair continues to grow.
How To Slow Down Underarm Hair Growth?

Underarm hair growth is primarily influenced by genetics and hormonal factors, and it’s challenging to naturally slow down its growth. However, there are a few lifestyle practices that may help manage the appearance or frequency of underarm hair growth:
Regular Exfoliation

Regular exfoliation of the underarm area can offer several benefits for skin health and overall appearance. While it doesn’t directly slow down hair growth, it can contribute to a smoother and more even skin texture. Exfoliation helps to slough off dead skin cells on the surface of the skin. This can prevent the buildup of debris, sweat, and bacteria, reducing the risk of clogged pores and ingrown hairs. Regular exfoliation can help to brighten the skin by removing dull, dead skin cells and revealing fresher, healthier skin underneath. This can contribute to a more radiant appearance.
Methods of exfoliation can include using a mild scrub, a gentle brush, or a chemical exfoliant containing ingredients like alpha-hydroxy acids (AHAs) or beta-hydroxy acids (BHAs). Be sure to follow the instructions provided with the chosen exfoliating product and moisturize the skin afterward to keep it hydrated.
Healthy Diet

Maintaining a healthy diet can contribute to overall well-being, including the health of your hair and skin. While it doesn’t directly slow down underarm hair growth, a balanced diet can support optimal hair growth and health. Consuming a variety of nutrient-rich foods ensures you’re getting the essential vitamins and minerals necessary for healthy hair and skin. These nutrients include vitamins A, C, E, and B-complex vitamins, as well as minerals like zinc, iron, and biotin.
They support the production of healthy hair follicles and promote skin health. Staying properly hydrated is important for maintaining healthy skin and hair. Drinking an adequate amount of water each day can help keep your skin hydrated and your hair follicles nourished.
Avoiding Hair-Stimulating Products

Avoiding hair-stimulating products can help manage the appearance of underarm hair growth, but it won’t directly slow down the rate of growth. Some topical creams or lotions contain hormones like testosterone or estrogen, which can potentially stimulate hair growth.
Avoid using such products in the underarm area if you’re concerned about hair growth. Some products used for treating or preventing ingrown hairs, such as exfoliating scrubs or creams, can potentially stimulate hair growth. If you’re concerned about hair growth, avoid using these products specifically for hair removal purposes.
Hormonal Balance

Maintaining hormonal balance is important for overall health and can indirectly influence hair growth, including underarm hair. Hormonal imbalances can sometimes contribute to excessive hair growth. Adopting a healthy lifestyle can promote hormonal balance. This includes regular exercise, adequate sleep, stress management, and avoiding excessive alcohol consumption and smoking. Chronic stress can disrupt hormone levels. Engaging in stress-reducing activities like meditation, yoga, deep breathing exercises, or hobbies can help manage stress and support hormonal balance.
Professional Hair Removal Methods

Professional hair removal methods are widely used for long-lasting or permanent reduction of underarm hair. These methods are typically performed by trained professionals and provide more effective and precise results compared to at-home methods. Including waxing, laser hair removal, electrolysis, epilation, shaving, and sugaring. When considering professional hair removal methods, it’s important to choose a reputable and experienced provider. They can assess your specific needs, discuss any potential risks or side effects, and recommend the most suitable method for your underarm hair removal goals.
