why hair grow so fast

Your hair grows rapidly due to genetic factors, hormonal imbalances like polycystic ovary syndrome (PCOS), or medications.

You may notice an abnormal spike in hair growth if your hormones are out of whack, or if excessive hair growth runs in your family.

Employing products like biotin gummies, minoxidil foam, or hair supplements can help control the growth cycle.

However, merely managing the symptoms won’t address the root cause.

To truly understand why your hair grows so fast, you’ll need to explore potential underlying conditions and treatment options.

Key Takeaways

  • Genetic factors, hormonal imbalances, and medications can cause rapid hair growth.
  • Hormonal imbalances can lead to excessive hair growth and may be caused by various factors such as hormonal disorders, medications, or genetic predispositions.
  • Genetics play a significant role in determining hair growth rate and the health of hair follicles.
  • Treatment options for excessive hair growth include hormonal therapy, birth control pills, lifestyle changes, hair growth oils, and vitamins.

Why Does Body Hair Grow Fast?

Why Does Body Hair Grow Fast
You may notice your body hair growing at an unusually rapid pace, which could be attributed to a hormonal imbalance, a genetic predisposition, or an underlying condition like polycystic ovary syndrome (PCOS). Certain medications can also stimulate excessive hair growth, so it’s imperative to determine the underlying cause to effectively manage this issue.

You Have a Hormonal Imbalance

You have a hormonal imbalance, which can be the reason why your body hair grows fast.

Hormonal imbalances can be caused by various factors, such as hormonal disorders, medications, or genetic predispositions.

For example, conditions like Cushing’s syndrome, anabolic steroid use, or thyroid issues can lead to an increase in cortisol levels, which can stimulate hair growth.

Additionally, hormonal contraceptives or hormone replacement therapy can affect the balance of hormones in the body, potentially impacting hair growth.

If you suspect a hormonal imbalance is causing your fast-growing body hair, it’s crucial to consult a medical practitioner or dermatologist for personalized advice and appropriate treatment options.

It Runs in the Family

It runs in the family: Genetics play a significant role in determining hair growth rate and the health of hair follicles.

If your family members have fast-growing or slow-growing hair, it’s likely that you’ll experience similar hair growth patterns.

This is because hair growth is influenced by genetic factors that determine the production of hormones connected to hair follicle development.

The anagen phase of the hair growth cycle, which is the most affected by genes, is responsible for hair strands pushing through the skin.

Genetics also influence hair color and texture, as well as the rate of hair growth throughout one’s life.

Hair growth rate can fluctuate with age, with the fastest growth typically occurring between 15 and 30 years old.

You May Have PCOS

If you have a hormonal imbalance, you may be experiencing rapid hair growth.

Polycystic ovary syndrome (PCOS) is a common cause of hormonal imbalances, and it can lead to excessive hair growth on the body. PCOS symptoms include irregular periods, acne, and weight gain.

PCOS treatments may involve hormonal therapy, birth control pills, or lifestyle changes such as diet and exercise.

Hair growth oils and vitamins can also help regulate hormonal imbalances and support healthy hair growth.

It’s Your Medication

Medications can substantially influence hair growth.

Certain drugs, such as retinoids, beta-blockers, antidepressants, and nonsteroidal anti-inflammatory drugs (NSAIDs), have been known to induce hair loss.

Conversely, medications like spironolactone and finasteride are employed to address hair loss.

Hormonal imbalances, such as those resulting from thyroid issues or Cushing’s syndrome, can also affect hair growth.

Stress can trigger telogen effluvium, a condition where hair prematurely enters the resting phase, resulting in hair shedding.

How to Slow Body Hair Growth

How to Slow Body Hair Growth
You can invest in a better shave by using high-quality razors, shaving creams or gels, and properly preparing your skin for a close, comfortable shave.

Alternatively, you may consider laser hair removal, which provides a more long-term solution for reducing unwanted hair growth by damaging the hair follicles and preventing future growth.

However, it’s essential to get to the underlying cause of excessive hair growth, whether it’s hormonal imbalances, genetics, or medications, and address those underlying factors for effective long-term management.

Invest in a Better Shave

Investing in a better shave isn’t just about ditching the fuzz; it’s an art form that respects your skin’s needs and tames the wild growth. Here’s how:

  1. Skin Preparation: Warm water and gentle exfoliation prep the canvas.
  2. Shaving Technique: Use a sharp, high-quality razor with precision.
  3. Shaving Cream: Choose one that soothes and protects.
  4. Aftershave Routine: Hydrate and calm with a nourishing aftershave.

Mastering these steps can slow the sprint of body hair growth, leaving your skin smoother for longer.

Consider Laser Hair Removal

Consider laser hair removal as a long-term solution for slowing down the growth of unwanted body hair.

It works by damaging the hair follicles, putting them into a state of dormancy for an extended period.

Although it’s not a permanent solution, it can markedly reduce the number of unwanted hairs in a given area.

For best results, it’s recommended to undergo multiple treatment sessions spaced six weeks apart, with most people needing between four and six sessions.

After the initial treatment cycle, occasional maintenance sessions may be required to prevent hair follicles from regenerating.

However, it’s crucial to consult a board-certified dermatologist for professional laser hair removal to ensure safety and effectiveness.

At-home laser hair removal devices may not be as advanced or appropriate for all skin types and colors.

Get to the Root of It

To decelerate body hair growth, it’s crucial to confront the underlying cause.

Genetics play a pivotal role, but you can impact hair follicle development through diet and stress management.

Ingest a balanced diet rich in protein, vitamins, and minerals to foster healthy hair growth.

Manage stress to prevent premature entry into the telogen stage, which can result in hair shedding.

Additionally, consider using hair supplements and hair care products that promote hair health.

Body Hair Maintenance Tips

Body Hair Maintenance Tips
To maintain your body hair and prevent excessive growth, you should avoid overwaxing or shaving too frequently, as this can stimulate the hair follicles and lead to thicker, coarser hair. Additionally, regular exfoliation helps remove dead skin cells and ingrown hairs, while moisturizing after hair removal can soothe irritation and prevent dryness, which can contribute to faster regrowth.

Avoid Over-Waxing or Shaving

Avoid over-waxing or shaving to prevent skin irritation, razor burn, and follicle damage. Opt for a better shave with a sharp razor, lubricating strip, and proper technique. Consider microneedling to stimulate collagen production and improve skin texture.

Exfoliate Regularly

Regular exfoliation is a vital step in maintaining healthy skin and fostering hair growth. Exfoliation methods can differ, and the ideal frequency depends on your skin type and the exfoliation technique you select. For sensitive skin, mild chemical exfoliants are often the preferred choice, as they’re less likely to induce irritation than physical exfoliators such as scrubs.

When it comes to exfoliating your scalp, the advantages extend beyond controlling hair growth. Scalp exfoliation can enhance skin tone and texture, boost collagen production, reduce blemishes, and brighten your skin. It also aids in unclogging the tissues, creating a suitable environment for healthy hair follicles to thrive.

For sensitive skin, it’s imperative to begin with a short-contact formula, such as a cleanser or rinse-off mask, to minimize the likelihood of irritation. Additionally, avoid exfoliators with fragrance, as they can be a common skin irritant.

Exfoliating products for sensitive skin should contain gentle ingredients such as salicylic acid, glycolic acid, polyhydroxy acid, and lactic acid. Polyhydroxy acids are particularly well-suited for sensitive skin, as they’re less likely to cause irritation compared to other acids.

Moisturize After Hair Removal

After hair removal, it’s crucial to moisturize your skin to maintain its softness and hydration. Here are three simple steps to follow:

  1. Select the Appropriate Moisturizer: Choose a gentle, fragrance-free moisturizer tailored to your skin type. If you have dry skin, consider a rich cream or lotion. For oily skin, opt for a lightweight gel or serum.
  2. Apply Regularly: Apply the moisturizer to the treated area daily, preferably after a shower or bath when your skin is still moist.
  3. Protect Your Skin: In the hours following hair removal, avoid direct sun exposure as your skin is more vulnerable to UV radiation. Always use sun protection to shield your skin from sunburn and hyperpigmentation.

When to See a Dermatologist

When to See a Dermatologist

If you’re experiencing unusual hair growth or hair loss, it’s essential to consult a dermatologist.

Hair loss can be a symptom of medical conditions like alopecia areata or trichotillomania.

Excessive hair growth may indicate hormonal imbalances or the use of certain medications.

Hair removal techniques and hair care products can also cause issues.

In the table below, we’ll explore when to see a dermatologist based on your concerns.


Ultimately, if your excessive body hair growth persists despite utilizing products and grooming techniques, it’s essential to consult a dermatologist.

They can pinpoint the underlying cause, whether it’s a hormonal imbalance, genetic predisposition, or an undiagnosed condition like PCOS.

They can recommend appropriate treatment options.

By addressing why your hair grows so fast at the root level, you can effectively manage and control unwanted hair growth.
