Quick Summary: Microneedling for Hair Loss
- What is Microneedling? Microneedling, or collagen induction therapy, uses tiny medical-grade needles to create micro-injuries on the scalp, promoting collagen production, release of growth factors and stimulating hair growth. It is a non-surgical treatment with little to no downtime, making it a popular choice for those seeking a less invasive option for hair loss.
- Other uses of microneedling: Microneedling is used to treat a variety of skin conditions that cause depressions in the skin such as acne scarring, general scars, enlarged pores, wrinkles, and stretch marks.
- Combining with Other Treatments: Microneedling can be combined with treatments like minoxidil and Platelet-Rich Plasma therapy to enhance hair growth.
- Side Effects: Common side effects include mild redness, irritation, or slight swelling at the treated area. Infection may occur if not performed in a sterile environment. For individuals on blood thinning medication, a temporary pause may be advised.
- Hair Transplants vs. Microneedling: While microneedling is effective for early-stage hair loss, hair transplants provide a more permanent solution for advanced baldness by surgically implanting healthy hair follicles into thinning and balding areas.
Hair loss is a common concern that affects millions of people worldwide. Among the various treatments available, microneedling has emerged as an innovative and effective option for stimulating hair growth. This guide will explore how microneedling works for hair loss, its benefits, potential side effects, and practical advice for those considering this treatment.
What is Microneedling?
Microneedling, also known as collagen induction therapy, involves using tiny medical-grade needles to create micro-injuries on the skin’s surface. The procedure uses instruments containing up to 540 needles that puncture the top layers of the skin – the epidermis and/or dermis. Each needle can range in size from 0.1 to 0.25 mm in diameter and 0.5 to 3 mm in length. These controlled punctures stimulate the body’s natural wound healing process, which promotes collagen production, triggers a release of growth factors and enhances blood flow to the treated area. Originally used for skincare, microneedling has gained popularity in recent years as a treatment for hair loss due to its ability to promote hair follicle health and stimulate hair growth1.
How Does Microneedling Stimulate Hair Growth?
Microneedling for hair loss works by promoting cellular regeneration in the scalp. When the skin is punctured by microneedles, the body responds by sending growth factors to the site, which helps stimulate hair follicles that may have entered a dormant phase. This process can result in thicker, healthier hair growth over time. Furthermore, the collagen produced maintains the hair follicles2.
Microneedling benefits individuals suffering from hair loss, particularly for those with androgenetic alopecia (male or female pattern baldness) or other non-scarring types of alopecia.
- Increases Product Absorption: Microneedling creates tiny microchannels in the scalp, which can increase the absorption of topical treatments like Minoxidil. This allows treatments to penetrate deeper into the skin, making them more effective than when applied on their own.
- Minimal Downtime: Unlike more invasive procedures, microneedling requires little to no downtime. Most individuals can resume their daily activities shortly after the procedure. Some redness or mild irritation may occur, but these effects typically subside within a day or two .
- Non-Surgical Treatment: Microneedling offers a non-surgical, minimally invasive option for treating hair loss. For individuals who are not candidates for hair transplant surgery or prefer a less invasive approach, microneedling can be an excellent alternative2.
Other Uses of Microneedling
Microneedling is used for a variety of skin-related treatments beyond hair restoration. Some common uses include:
- Anti-aging treatments: Microneedling helps reduce the appearance of fine lines, wrinkles, and sagging skin by stimulating collagen and elastin production, which enhances skin firmness and texture.
- Acne scars and other scarring: It is effective in diminishing the appearance of acne scars, surgical scars, and other types of scarring, by promoting skin repair through collagen synthesis.
- Hyperpigmentation and uneven skin tone: Microneedling can help improve hyperpigmentation and even out skin tone by promoting cell turnover and skin rejuvenation.
- Stretch marks: It is also used to reduce the appearance of stretch marks by promoting the regeneration of skin in affected areas.
- Large pores: Microneedling can help reduce the appearance of large pores by tightening the skin around them, giving the skin a smoother appearance3.
Common Microneedling Devices
Microneedling is typically performed using various devices designed to create controlled micro-injuries in the skin. Each device varies in terms of needle depth, penetration, and additional technologies, depending on the desired treatment outcomes and the area being treated. Always consult with a licensed practitioner to determine the best device for your needs. Here are some commonly used microneedling devices:
- Dermaroller: A handheld roller device covered with small needles that is rolled over the skin to create microchannels. It is often used for home treatments but is also utilised in professional settings.
- Dermapen: A pen-shaped device with multiple fine needles at the tip that move up and down in a stamping motion. This device is commonly used by professionals for more precise treatment of smaller areas like the face.
- Radiofrequency Microneedling Devices: These combine traditional microneedling with radiofrequency energy to deliver heat deeper into the skin, enhancing collagen production and improving the treatment of scars, wrinkles, and skin tightening.
- Automated Microneedling Devices: These advanced devices use motorized needles to adjust the depth of penetration, offering more control and consistent results.
- HydraRollers: A hybrid device that combines microneedling with the infusion of serums directly into the skin, often used to enhance hydration and skin rejuvenation4.
Microneedling Procedure for Hair Loss
The microneedling procedure for hair loss is straightforward and typically performed by a dermatologist or a trained professional. Most patients require multiple sessions of microneedling to achieve optimal results. Sessions are typically spaced 4 to 6 weeks apart, with noticeable improvements in hair growth after 6 months. Here’s what to expect:
- Consultation and Assessment: Before starting treatment, a consultation with a dermatologist or hair loss specialist is necessary to assess your scalp and determine if microneedling is the right treatment for you. They will also evaluate the underlying cause of your hair loss and recommend a personalised treatment plan.
- Preparation: During the procedure, the scalp is cleansed to ensure that the area is free of debris or oils. A numbing cream may be applied to minimise discomfort during the treatment, although the pain from microneedling is generally mild.
- Microneedling Process: A microneedling device, often a dermaroller or a dermapen, is used to create tiny punctures in the scalp. The depth of the needles varies depending on the severity of hair loss and the individual’s scalp condition. The process usually takes 20 to 30 minutes, depending on the area being treated.
- Post-Treatment Care: After the procedure, it’s important to avoid washing the scalp for 24 hours to allow the skin to heal. Redness and minor swelling are common side effects, but these typically resolve within a day or two. Your doctor may recommend using specific topical treatments post-microneedling to enhance results5.
Combining Microneedling with Other Treatments for Hair Loss
Studies suggest that microneedling may be particularly effective when combined with other treatments, as the microchannels created by microneedling can enhance the absorption of topical treatments. Some of the most common combinations include:
- Microneedling with Minoxidil: Minoxidil is a widely used topical treatment for hair loss, as it promotes hair growth by increasing blood flow to the hair follicles. Studies have shown that combining it with microneedling can significantly enhance its effectiveness. The microchannels created by microneedling allow minoxidil to penetrate the scalp more deeply, leading to improved hair growth results6.
- Microneedling with Platelet-Rich Plasma (PRP): PRP therapy involves drawing a patient’s blood, separating the plasma, and injecting it into the scalp. When combined with microneedling, PRP can boost hair growth by delivering growth factors directly to the hair follicles, further enhancing the regenerative effects of microneedling7.
Potential Side Effects and Risks
While microneedling is generally considered a safe treatment, there are some potential side effects and risks to be aware of. It’s important to have microneedling performed by a trained professional to minimise the risk of complications and ensure optimal results.
These include:
- Redness and Irritation: Mild redness and irritation are common immediately after treatment, but these symptoms usually subside within a day or two.
- Infection: There is a small risk of infection if the procedure is not performed in a sterile environment or if proper aftercare is not followed. Antibiotic cream can be prescribed to treat the infection.
- Pain or Discomfort: Some individuals may experience mild discomfort during the procedure, but this can be minimised with the use of a numbing cream or over-the pain relief medication4.
Who is a Good Candidate for Microneedling?
Microneedling can be an effective treatment for individuals experiencing hair thinning or loss due to androgenetic alopecia or other non-scarring alopecias. However, it may not be suitable for everyone.
Ideal candidates for microneedling include:
– Individuals with early to moderate stages of hair loss.
– Those looking for a non-invasive treatment option.
– People seeking to enhance the effectiveness of topical treatments like minoxidil.
Individuals who may not be ideal candidates for microneedling include:
– Those with active scalp infections or skin conditions.
– Individuals with scarring alopecia (such as lichen planopilaris) may not respond well to microneedling .
– People with bleeding disorders or those taking blood-thinning medications should consult their healthcare provider before undergoing microneedling. Blood thinners, such as warfarin, aspirin, and certain anticoagulants, reduce the body’s ability to form blood clots, which can lead to excessive bleeding or bruising during and after microneedling.
Practical Tips for Success
If you are considering microneedling for hair loss, here are some practical tips to maximise your success:
- Choose a Qualified Professional: Ensure that the procedure is performed by a trained professional, preferably a dermatologist or hair loss specialist.
- Follow Aftercare Instructions: Adhering to post-treatment care, such as avoiding sun exposure and refraining from washing your scalp for 24 hours, is crucial for optimal results.
- Be Patient: Hair growth is a gradual process, and it may take several months before you see noticeable improvements.
- Consider Combination Therapies: Speak with your doctor about combining microneedling with other treatments like minoxidil or PRP to enhance hair growth. At The Treatment Rooms London, we would be happy to advise.
Hair Transplants vs. Microneedling: Which is Right for Your Hair Loss?
Hair transplants and microneedling are both used to address hair loss, but they differ significantly in terms of approach and results. Hair transplants involve surgically removing healthy hair follicles from a donor area (typically the back and sides of the scalp) and implanting them into thinning or bald areas such as the hairline, temple or crown. This method offers a permanent and highly effective solution, particularly for those with advanced hair loss8.
While microneedling is less invasive and can be a good option for early-stage hair loss, hair transplants are generally more suitable for individuals with significant hair thinning or balding who require a more permanent and noticeable solution. Please do not hesitate to consult with our skilled surgeons, who are ready to guide you through your treatment options and provide expert advice on the best approach for your hair restoration journey. We’re here to address any questions or concerns you may have and ensure you feel confident in your decision.
Conclusion
Microneedling is an exciting and effective option for treating hair loss. By stimulating hair follicle regeneration and improving the absorption of topical treatments, microneedling offers a non-invasive solution for individuals experiencing hair thinning or loss. While it may not be suitable for everyone, many people see significant improvements after multiple sessions. As with any medical treatment, it’s important to consult with a qualified professional to determine the best approach for your specific condition.
