Microneedling for Hair Growth

Hair loss is a common concern affecting millions of men and women worldwide. It can be a gradual thinning or a more sudden experience, and the emotional impact can be significant.

Many traditional solutions exist, from topical medications to hair transplants. However, these solutions often have limitations  –  limited effectiveness, unwanted side effects, or high costs.

In the ongoing search for effective hair loss treatments, a new option has emerged: microneedling. This minimally invasive procedure has gained traction, but the question remains: Does microneedling hold promise for hair regrowth?

This blog will discuss the science behind microneedling for hair loss, explore its potential benefits, and learn who might be a good candidate for this treatment.

What Is Microneedling?

Microneedling, or collagen induction therapy, is a minimally invasive procedure using a sterile device containing fine needles. This device, often resembling a pen, is gently rolled across the scalp. The tiny needles create controlled micro-injuries in the uppermost layer of the skin (epidermis) and potentially reach the deeper dermal layer.

These micro-punctures are a signal to your body.  They trigger the body’s natural wound-healing response, which involves increased blood flow to the area and the production of collagen and elastin – essential building blocks for healthy skin and hair follicles.

Can Microneedling Help with Hair Loss?

The theory behind microneedling for hair growth is centred around its ability to stimulate the scalp environment. Here’s how it might work:

  • Increased blood flow – The micro-injuries created by microneedling trigger an influx of blood to the scalp. This increased blood flow delivers essential nutrients and oxygen to hair follicles, potentially promoting hair growth.
  • Stimulation of collagen production – Collagen is a crucial protein supporting hair follicles’ health and structure. Microneedling stimulates collagen production, potentially creating a more favourable environment for hair growth.
  • Improved fair follicle health – The combination of increased blood flow and collagen production could lead to improved hair follicle health. This may translate to thicker, stronger hair and encourage hair growth in areas with thinning.

However, it’s important to address the current state of research on microneedling for hair loss. While some studies have shown promising results, with participants experiencing increased hair growth and improved scalp health, these studies are often limited in scope.

More extensive research is needed to solidify microneedling’s effectiveness as a standalone hair loss treatment.

Potential Benefits of Microneedling for Hair Loss

Based on available research, microneedling shows promise for individuals experiencing hair loss. Here are some potential benefits:

  1. Encouraging Hair Growth in Thinning Areas

Studies suggest that microneedling may promote hair growth in areas with thinning hair. The increased blood flow and collagen production stimulated by the procedure could create a more conducive environment for hair follicles to transition from resting to growth.

  1. Improving the Health of Existing Hair Follicles

Microneedling encourages new hair growth and could improve the health of existing hair follicles. This could lead to stronger, thicker hair strands, potentially improving your hair’s overall quality and density.

It’s better to manage expectations. While microneedling offers a promising approach, it’s unlikely to regrow hair in areas that are already bald completely.  However, microneedling could be a valuable tool to stimulate growth and improve hair health for individuals with early signs of hair loss or thinning hair.

Who Is a Good Candidate for Microneedling for Hair Loss?

Microneedling for hair loss might be a suitable option for individuals experiencing:

  • Early signs of hair loss – If you notice a gradual receding hairline or diffuse thinning across your scalp, microneedling could be a proactive approach to stimulate hair growth and improve hair density.
  • Thinning hair – For thinning hair, microneedling may help revitalize hair follicles, leading to thicker, stronger strands and potentially promoting new growth.
  • Alopecia areata – This autoimmune form of hair loss causes patchy bald spots. While research is ongoing, some studies suggest microneedling may be beneficial for stimulating hair regrowth in areas affected by alopecia areata.

However, consulting with a dermatologist is the most important step before undergoing microneedling for hair loss. A dermatologist can provide a personalized assessment to determine if you’re a good candidate for this treatment.

Here’s why a consultation with a dermatologist is essential:

  • Scalp health evaluation – A dermatologist can examine your scalp for underlying conditions that might contraindicate microneedling, such as infections or scarring.
  • Hair type analysis – Different hair types respond differently to treatments. Your dermatologist will assess your hair type to determine the appropriate needle depth and treatment plan for optimal results.
  • Understanding hair loss cause – Identifying the root cause of your hair loss is vital. Microneedling may not be effective for all types of hair loss, and a dermatologist can recommend alternative or complementary treatments if necessary.

By thoroughly consulting a qualified dermatologist, you can ensure microneedling is safe and effective for addressing your hair loss concerns.

Dermatologists can create a personalized treatment plan that may combine microneedling with other hair loss solutions to maximize results.

What to Expect with Microneedling for Hair Loss

The microneedling procedure for hair loss is typically performed in a dermatologist’s office and can be completed in about 30 minutes. Here’s a general overview:

  1. Preparation – Your scalp will be cleansed and sanitized. A topical anesthetic may be applied to minimize discomfort, depending on your sensitivity.
  2. The microneedling process – The dermatologist will use a sterile microneedling device to glide gently across your scalp. The needles create tiny punctures, stimulating the targeted areas. Your dermatologist will determine the needle depth used based on your individual needs.
  3. Post-treatment – You may experience temporary redness and mild discomfort following the procedure, similar to a sunburn. This typically resolves within 24-48 hours.

The frequency of micro needling sessions for hair loss can vary depending on several factors, including:

  • Severity of hair loss – Individuals with more advanced hair loss may require more frequent sessions than those with early signs of thinning.
  • Treatment goals – The desired outcome will influence the treatment plan. More aggressive goals may necessitate more frequent sessions.
  • Individual response – Everyone heals at their own pace, and your dermatologist will tailor the frequency based on your body’s response to the treatment.

Most patients generally see optimal results with microneedling sessions spaced 4-6 weeks apart.  Your dermatologist will recommend the optimal frequency for achieving your desired results.

Microneedling can also be combined with other hair loss treatments for better results. Here are two examples:

  • Minoxidil

This topical medication is a common treatment for hair loss. Combining microneedling with minoxidil may enhance the medication’s absorption and effectiveness.

  • Platelet-rich plasma (PRP)

PRP therapy involves injecting concentrated platelets into the scalp. PRP is rich in growth factors that can further stimulate hair growth.

When combined with microneedling, the tiny channels the needles create may allow for deeper penetration of the PRP, potentially maximizing its benefits.

Keep in mind that microneedling for hair loss is not a one-size-fits-all solution. Consulting with a dermatologist is crucial to determine if microneedling is right for you and to discuss the potential benefits of combining it with other hair loss treatments.

Your Next Steps for Hair Growth with Microneedling

Microneedling has emerged as a promising approach for hair loss, offering the potential to stimulate hair growth, improve hair follicle health, and promote thicker, stronger hair. However, it’s important to remember that individual results can vary.

The timeframe for seeing noticeable improvements depends on several factors, including the severity of hair loss, treatment frequency, and your body’s response.

The key to achieving optimal results with microneedling lies in consulting with a qualified dermatologist. They can assess your situation, determine if microneedling suits you, and create a tailored treatment plan.
