Laser Hair Removal And Hormonal Hair Growth: What To Know

Laser Hair Removal And Hormonal Hair Growth: What To Know

Laser hair removal is one of the most effective and popular methods for managing unwanted hair growth, particularly for individuals seeking long-term hair reduction

However, its success is influenced by various factors, including hormonal influences. Hormones regulate hair growth cycles and can significantly impact the outcomes of laser hair removal treatments, especially for individuals with hormonal imbalances

This guide explores laser hair removal and hormonal hair growth: what to know, including how to achieve desired results despite hormonal challenges.

Let’s get straight to the point

Laser hair removal is a highly effective method for long-term hair reduction, but its success can be influenced by hormonal imbalances such as those caused by PCOS, thyroid disorders, or menopause. Hair grows in cycles, and laser treatments target the active growth phase, requiring multiple sessions for optimal results. 

Hormones like androgens and oestrogens significantly affect hair growth patterns, necessitating personalised treatment plans for individuals with hormonal conditions.

By consulting with experienced professionals and adhering to pre-treatment and maintenance guidelines, clients can achieve lasting hair reduction and manage unwanted growth effectively, even in hormonally sensitive areas.

 

Understanding Hair Growth

Understanding how hair grows is fundamental to the success of laser treatments. Hair growth varies by individual and is impacted by genetics, hormones, and the growth cycle.

Hair Growth Cycles

Hair grows in three distinct phases:

  1. Anagen Phase (Active Growth): Hair is actively growing from the hair follicle, and this phase is the target of laser hair removal.
  2. Catagen Phase (Transition): Hair growth stops, and the follicle begins to shrink.
  3. Telogen Phase (Resting): The hair is shed, and the follicle remains dormant before restarting the cycle.

Laser hair removal targets the pigment in the hair shaft during the anagen phase when the follicle is most active. As only a portion of hair is in this phase at any given time, repeated treatments are essential to capture all active hair follicles.

How Hormones Influence Hair Growth Cycles

Hormones such as androgens and oestrogens play a critical role in regulating hair growth patterns:

  • Androgens: Promote hair growth in areas like the face, chest, and back. High levels of androgens can cause excessive hair growth or hirsutism.
  • Oestrogens: Enhance hair growth on the scalp while reducing body hair growth in some areas.

These hormonal effects vary significantly by gender, age, and underlying medical conditions.

Hormonal Imbalances And Hair Growth

Hormonal imbalances can disrupt normal hair growth cycles and lead to issues like unwanted hair growth or hair thinning. Below are some common conditions that influence hair growth patterns.

Polycystic Ovary Syndrome (PCOS)

PCOS is a hormonal disorder that affects women of reproductive age. It is characterised by elevated androgen levels, which can lead to:

  • Excessive hair growth on the face, chest, and back.
  • Irregular periods and acne.
  • Resistance to typical hair removal methods, requiring more treatment sessions for effective management.

Thyroid Disorders

Thyroid hormones are essential for healthy hair growth. Disorders include:

  • Hyperthyroidism (Overactive Thyroid): Causes hair thinning and excessive shedding.
  • Hypothyroidism (Underactive Thyroid): This leads to coarse, dry hair and, occasionally, increased hair growth in unusual areas.

These conditions require tailored treatment plans for optimal results.

Menopause

During menopause, hormonal fluctuations often result in unwanted facial hair and thinning scalp hair. The decrease in oestrogen levels and an increase in androgens can cause these changes. Laser hair removal is particularly effective for managing unwanted hair growth during this stage.

Lase Hair Removal As An Effective Solution For Excessive Hair Growth

Laser hair removal uses concentrated light beams to target and destroy the hair follicle, inhibiting its ability to grow new hair. The pigment in the hair shaft absorbs the laser’s energy, which damages the follicle and disrupts the hair growth cycle.

This method is particularly effective for individuals with dark hair and light skin, as the contrast allows the laser beam to focus on the pigment without damaging surrounding tissue.

For those experiencing excessive hair growth due to hormonal imbalances, laser hair removal offers several benefits:

  • Precision in targeting unwanted hair without damaging the skin.
  • Long-term reduction in future hair growth, resulting in hair-free skin.
  • Improved confidence and ease of managing areas prone to unwanted hair growth, such as the face and bikini line.

Customised Treatment Plans

Tailored To Individual Needs

Personalised treatment plans are essential for clients dealing with hormonal conditions that affect hair growth patterns. These plans consider factors such as:

  • The client’s skin type, hair colour, and hair growth cycles.
  • Hormonal conditions like PCOS, thyroid disorders, or menopause.

This may involve scheduling more frequent sessions or adjusting the laser settings to target the hair follicles effectively. Ongoing monitoring allows professionals to adjust the approach based on hormonal fluctuations.

Achieving Optimal Results

Number Of Sessions Needed

To achieve optimal results, patients typically require 3-4 sessions spaced a few weeks apart. However, the number of sessions may vary depending on:

  • The individual’s hair growth patterns.
  • The presence of hormonal imbalances may require more treatment sessions to achieve significant hair reduction.

Longevity Of Results

Laser hair removal results can last up to 18 months, with maintenance sessions extending the benefits. The longevity of results depends on:

  • The client’s hair growth cycles.
  • Hormonal influences that may stimulate future hair growth.
  • The individual’s response to the treatment.

Preparing For Laser Hair Removal

Pre-Treatment Preparations

To maximise the effectiveness of laser treatments, certain preparations are necessary:

  1. Avoid waxing, plucking, or any methods that remove the hair follicle for at least six weeks before treatment.
  2. Shave the treatment area 24 hours before your appointment to ensure the laser targets the hair shaft directly.
  3. Share your medical history with your specialist, including any hormonal conditions like PCOS or thyroid disorders.

Consultation And Testing

A thorough consultation with an expert is crucial. Testing for hormonal imbalances may be recommended to design a treatment plan tailored to your specific needs. This ensures the best chance of achieving significant hair reduction.

Frequently Asked Questions

Can Laser Hair Removal Effectively Treat Hormonal Hair Growth?

Laser hair removal can reduce hormonal hair growth, but results may vary depending on the underlying hormonal imbalance. It targets hair follicles to slow and reduce regrowth, but new hairs may still develop if hormones stimulate additional follicles. Combining laser treatment with hormonal therapy can enhance effectiveness.

What Causes Hormonal Hair Growth, And How Does It Affect Laser Treatment?

Hormonal hair growth is often caused by conditions like polycystic ovary syndrome (PCOS), pregnancy, menopause, or thyroid issues. These hormonal fluctuations can lead to excessive or stubborn hair growth. While laser hair removal can manage existing hair, ongoing hormonal activity may require maintenance sessions to address new growth.

How Many Laser Sessions Are Needed For Hormonal Hair Growth?

People with hormonal hair growth typically require more sessions than average, often 8–12 or more, spaced 4–6 weeks apart. Maintenance sessions may also be necessary to manage regrowth caused by ongoing hormonal imbalances. A consultation with a professional can provide a personalised treatment plan.

Are There Specific Lasers That Work Better For Hormonal Hair Growth?

Yes, certain lasers like the Diode or Nd:YAG are particularly effective for targeting coarse and dark hairs commonly associated with hormonal growth. These lasers are designed to work on a wide range of skin tones and hair types, ensuring safe and efficient results.

Can Laser Hair Removal Stop Hormonal Hair Growth Permanently?

While laser hair removal can significantly reduce hair growth and make it less noticeable, it does not stop hormonal hair growth permanently. If hormonal imbalances persist, they may stimulate new hair growth. Combining laser treatments with medical management of hormonal issues offers the best long-term solution.
