Types of Armpit Hair

To understand armpit hair growth, it is essential to recognize the different types of armpit hair. This will help you better understand the stages of hair growth and how to manage it effectively. Knowing the differences between terminal hair and vellus hair is crucial in this regard.

Terminal Hair Vellus Hair
Thicker, darker, and more noticeable Fine, light, and barely noticeable
Longer growth phase Shorter growth phase
Main type of hair in adults Common in children
Increased during androgenic puberty Does not change during puberty
Mainly found in armpits, pubic areas, and face Found all over the body

Terminal Hair

Terminal hair is the type of hair that is thicker, darker, and more noticeable. It has a longer growth phase and is the main type of hair in adults. During androgenic puberty, the amount of terminal hair increases, making it more prominent in the armpits, pubic areas, and face.

Vellus Hair

Vellus hair, on the other hand, is fine, light, and barely noticeable. It has a shorter growth phase and is common in children. Unlike terminal hair, vellus hair does not change during puberty and can be found all over the body.

Factors Affecting Armpit Hair Growth

Some factors can affect the rate of armpit hair growth. These include hormonal changes, genetics, age, and overall health.

  • Hormonal changes: fluctuations in hormone levels can impact the speed of hair growth
  • Genetics: family history plays a role in determining the thickness and length of armpit hair
  • Age: hair growth may slow down as you get older
  • Overall health: a balanced diet and proper hydration can support healthy hair growth

Perceiving the impact of these factors on your own hair growth can help you better understand and manage it.

Hormonal Factors

Changes in hormone levels can significantly impact the growth of armpit hair. During puberty, the surge of hormones can lead to an increase in hair growth in the armpit area. Similarly, hormonal changes during pregnancy or menopause can also affect the rate of hair growth in this area. This is due to the influence of hormones such as testosterone and estrogen on the hair follicles.

This hormonal influence can result in varying growth rates and thickness of armpit hair. Additionally, certain medical conditions or medications that affect hormone levels may also contribute to changes in armpit hair growth.


Genetics play a significant role in determining the patterns of hair growth throughout our bodies, including the armpits. The genes inherited from your parents can influence the density, color, and texture of your armpit hair. If your family members have thick or coarse armpit hair, it is likely that you will experience similar hair growth patterns.

Stages of Armpit Hair Growth

Not all hairs on your body grow at the same rate or follow the same cycle. Understanding the stages of armpit hair growth can help you better manage and maintain it. The hair growth cycle consists of three main phases: anagen, catagen, and telogen. Each phase plays a crucial role in the overall growth and shedding of your armpit hair.

Anagen Phase

In the anagen phase, your armpit hair is actively growing. This phase can last anywhere from two to seven years, during which your hair can grow up to 1.5 centimeters per month. This is the most active phase of hair growth and is the time when your hair is healthiest and strongest. To help your armpit hair thrive during the anagen phase, it’s important to maintain a healthy diet, stay hydrated, and use nourishing hair care products.

Catagen Phase

During the catagen phase, your armpit hair stops growing and transitions into a resting state. This short phase, lasting only a few weeks, is characterized by the shrinking of the hair follicle and the detachment of the hair shaft from the root. This phase is a natural part of the hair growth cycle and prepares the hair for shedding and regrowth. While the hair may appear dormant, it is still connected to the follicle and will eventually enter the next phase of growth.

Telogen Phase

The telogen phase, also known as the shedding phase, marks the end of the hair growth cycle. In this phase, your armpit hair is released from the follicle and falls out, making room for new hair to begin growing. This phase can last for around three months and is followed by the return to the anagen phase for the newly grown hair. It’s normal to shed between 50 to 100 hairs from your armpits each day during the telogen phase. However, excessive hair shedding may indicate an underlying health issue or hormonal imbalance.

Tips for Shaving Armpit Hair

After allowing your armpit hair to grow to a length you are comfortable with, it’s time to shave. Here are some important tips to keep in mind to ensure a smooth and irritation-free experience.

  • Use a Sharp Razor
  • Exfoliate before Shaving
  • Moisturize after Shaving

Perceiving these tips will help you achieve the best results when shaving your armpit hair.

Use a Sharp Razor

When shaving your armpit hair, it’s crucial to use a sharp razor to avoid irritation and cuts. Dull blades can pull at the hair and cause discomfort, so make sure to replace your razor regularly. I recommend using a razor specifically designed for sensitive skin to minimize the risk of irritation.

Exfoliate before Shaving

Before shaving your armpit hair, it’s essential to exfoliate the area to remove dead skin cells and prevent ingrown hairs. You can use a gentle exfoliating scrub or a loofah to achieve smooth and clean skin. This step is crucial for preventing irritation and achieving a closer shave.

Moisturize after Shaving

After shaving, it’s important to moisturize your armpits to soothe the skin and prevent dryness. Opt for a gentle, fragrance-free moisturizer to avoid any potential irritation. Keeping the skin hydrated will also help reduce the risk of ingrown hairs and discomfort.

Pros and Cons of Shaving Armpit Hair

Now, let’s take a closer look at the advantages and disadvantages of shaving armpit hair. Shaving is a personal choice, and it’s important to weigh the pros and cons before deciding whether it’s the right option for you.


Shaving your armpit hair can have several benefits. Firstly, it can help to reduce body odor. When you have less hair in your armpits, there is less surface area for bacteria to multiply, which can lead to a decrease in unpleasant odors. Additionally, shaved armpits can also feel cooler, especially during hot weather or physical activity. Lastly, many people find that smooth, hair-free armpits can boost their confidence and make them feel more comfortable wearing sleeveless or strapless clothing.


On the other hand, there are some drawbacks to keep in mind. One of the most common concerns is the potential for skin irritation and ingrown hairs. Shaving can cause tiny cuts or nicks in the skin, leading to redness, itching, and discomfort. Ingrown hairs, which occur when the hair curls back into the skin instead of growing out, can also be painful and unsightly. Additionally, some people find that the regrowth of stubble can be itchy and bothersome. Finally, regular shaving requires time and effort, as the armpit hair will need to be maintained on a regular basis.


With this in mind, it is important to understand that armpit hair growth varies from person to person. However, on average, it takes about 30-60 days for armpit hair to grow to a noticeable length. Understanding the stages of hair growth, from anagen to telogen, can help you better manage and maintain your armpit hair. Whether you choose to shave or let it grow, it’s important to find a routine that works for you and your personal preferences. And always remember, the choice to shave or not to shave is entirely up to you.


Q: How long does it take for armpit hair to grow?

A: On average, armpit hair can grow at a rate of about 0.27 millimeters per day. It takes approximately 2-4 weeks for armpit hair to become visibly noticeable after shaving or waxing. However, the actual growth rate can vary depending on factors such as genetics, hormones, and age.

Q: What are the stages of hair growth?

A: The stages of hair growth are anagen, catagen, and telogen. Anagen is the active growth phase, catagen is the transitional phase, and telogen is the resting phase. Understanding these stages can help in managing and maintaining armpit hair growth.

Q: How can I encourage faster armpit hair growth?

A: While genetics play a significant role in hair growth, maintaining a healthy diet and taking supplements that contain vitamins and minerals such as biotin, vitamin A, and vitamin C may help support hair growth. Additionally, avoiding stress and getting enough sleep can also contribute to healthier and faster hair growth.

Q: When is the best time to shave armpit hair?

A: The best time to shave armpit hair is usually during or after a warm shower when the hair is softened. Using a sharp razor and shaving cream can help achieve a clean shave without causing irritation or ingrown hairs.

Q: How can I prevent ingrown hairs when shaving armpits?

A: To prevent ingrown hairs when shaving armpits, exfoliate the skin before shaving to remove dead skin cells and use a sharp, clean razor. After shaving, apply an alcohol-free soothing lotion to moisturize and calm the skin. Avoid tight clothing and use gentle, non-alcoholic deodorants to prevent irritation and ingrown hairs.
