Hair loss is a common concern affecting millions of people worldwide, leading to a growing interest in various treatments that can help to reverse or manage the condition. One of the emerging treatments in the field of hair restoration is microneedling. But does microneedling really help reverse hair loss? Let’s explore the science behind this treatment and its effectiveness.
What is Microneedling?
Microneedling, also known as collagen induction therapy, is a minimally invasive procedure that involves using a device with fine needles to create tiny punctures in the skin. This process stimulates the body’s natural healing response, promoting collagen and elastin production. Originally used for skin rejuvenation, microneedling has gained popularity for its potential benefits in treating hair loss.
How Does Microneedling Work for Hair Loss?
Microneedling works for hair loss by creating controlled micro-injuries on the scalp. These micro-injuries trigger the body’s wound healing process, which includes the release of growth factors and an increase in blood flow to the area. This enhanced circulation and nutrient delivery can help to:
1. Stimulate Hair Follicles: The micro-injuries can activate dormant hair follicles, encouraging them to enter the growth phase (anagen phase) and produce new hair.
2. Increase Collagen Production: Collagen is a critical component of healthy hair and scalp. Increased collagen production can strengthen hair follicles and improve the overall health of the scalp.
3. Enhance Topical Treatments: Microneedling can improve the absorption of topical treatments such as minoxidil (Rogaine) or hair growth serums, making these treatments more effective.
Scientific Evidence
Several studies have investigated the effectiveness of microneedling for hair loss, particularly androgenetic alopecia (pattern baldness):
• A 2013 study published in the International Journal of Trichology found that patients who received microneedling treatments in combination with minoxidil showed significantly greater hair regrowth compared to those who used minoxidil alone.
• A 2017 study published in Journal of Cosmetic Dermatology reported that microneedling combined with topical minoxidil resulted in better hair density and thickness compared to minoxidil alone.
• A 2018 study in The Journal of Clinical and Aesthetic Dermatology demonstrated that microneedling increased the expression of hair growth-related genes, suggesting a molecular basis for its effectiveness.
Procedure and Safety
Microneedling for hair loss is typically performed using a dermaroller or a dermapen device. The needles used are usually between 0.5 to 1.5 mm in length, depending on the specific needs of the patient. The procedure can be performed in a dermatologist’s office or at home with proper guidance and devices designed for personal use.
While microneedling is generally considered safe, it is essential to follow proper hygiene practices to avoid infections. Common side effects include redness, swelling, and minor discomfort, which typically subside within a few days.
Combining Microneedling with Other Treatments
Microneedling can be effectively combined with other hair loss treatments for enhanced results. Some popular combinations include:
• Minoxidil: Microneedling can increase the absorption and efficacy of minoxidil, leading to improved hair regrowth.
• PRP Therapy: Platelet-rich plasma (PRP) therapy involves injecting concentrated platelets from the patient’s blood into the scalp. When combined with microneedling, PRP can further stimulate hair growth and improve scalp health.
• Stem Cell Therapy: Applying stem cell serums or extracts after microneedling can enhance the regenerative effects, promoting hair growth and follicle health.
Conclusion
Microneedling is a promising treatment for reversing hair loss, with scientific studies supporting its effectiveness. By stimulating hair follicles, increasing collagen production, and enhancing the absorption of topical treatments, microneedling can help to promote hair regrowth and improve scalp health. However, as with any medical treatment, it is important to consult with a qualified healthcare professional to determine the best approach for your specific needs and to ensure safe and effective results.
If you are considering microneedling for hair loss, discuss it with your dermatologist to understand the potential benefits and risks, and to develop a personalised treatment plan.
Frequently Asked Questions
What is microneedling for hair loss?
Microneedling for hair loss is a procedure that uses fine needles to create tiny punctures in the scalp, which can stimulate hair growth by promoting collagen production and increasing blood flow to hair follicles.
How does microneedling help with hair loss?
The micro-injuries caused by microneedling trigger the body’s natural healing process, which includes the release of growth factors that can help to rejuvenate hair follicles and promote hair growth.
Is microneedling effective for all types of hair loss?
Microneedling is particularly effective for androgenetic alopecia (pattern baldness), but it may also help with other types of hair loss. It’s best to consult with a specialist to determine if microneedling is suitable for your specific condition.
How often should I undergo microneedling for hair loss?
The frequency of microneedling sessions can vary, but typically, treatments are spaced 2 to 4 weeks apart. Your Specialist will recommend a schedule based on your specific needs and goals.
Can microneedling be combined with other hair loss treatments?
Yes, microneedling is often combined with other treatments such as minoxidil (Rogaine), platelet-rich plasma (PRP) therapy, and stem cell serums to enhance results.
What should I expect during a microneedling session for hair loss?
During the session, a topical anaesthetic can be applied to the scalp to minimise discomfort. For some patients we don't recommend this as the hair can get greasy. The microneedling device is then used to create tiny punctures in the scalp, followed by the application of any additional treatments, such as serums or PRP. At Dr Aesthetica, our signature Root Revival can be used to reduce loss of hair, restore the scalp and increase hair production
Are there any side effects of microneedling for hair loss?
Common side effects include redness, swelling, and mild discomfort, which usually subside within a few days. Serious side effects are rare but can include infection if proper hygiene is not maintained.
How long does it take to see results from microneedling for hair loss?
Some individuals may notice improvements within a few weeks, but it typically takes several months to see significant results, as hair growth cycles can vary. Generally the first step is to reduce shedding, the second step is maintain current hair and then to see third step which is new growth of hair.
Is microneedling for hair loss safe?
Microneedling is generally considered safe when performed by a qualified professional. It is important to follow pre- and post-procedure instructions to minimize the risk of complications.
Can I perform microneedling for hair loss at home?
While home microneedling devices are available, professional treatments are recommended for safety and effectiveness. If you choose to do it at home, ensure you follow proper guidelines and use devices designed for personal use.
