What is Microneedling?

Microneedling is a cosmetic procedure that involves creating tiny punctures in the skin or scalp using a device equipped with fine needles. These micro-injuries stimulate the body’s natural healing response, promoting increased blood flow and collagen production. 

Microneedling scalp treatments are specifically designed to address hair loss by focusing on the health and functionality of hair follicles. This makes them an ideal option for restoring hair growth.

How Microneedling Promotes Hair Growth

Microneedling scalp treatment is highly effective in creating an optimal environment for hair regrowth by addressing multiple underlying factors that contribute to hair loss. 

1. Helps with Collagen Production

  • Stimulate Collagen Synthesis: Microneedling triggers the production of collagen, a protein that strengthens the scalp’s structural integrity.
  • Improve Skin Elasticity: By increasing collagen levels, microneedling enhances the elasticity of the scalp, allowing hair follicles to function in a healthier environment.
  • Reduce Follicle Shrinkage: Collagen strengthens the area around hair follicles, preventing miniaturization, which often leads to hair thinning.

2. Regenerate Cell

  • Activate Cellular Repair Mechanisms: The controlled micro-injuries caused by microneedling stimulate the body to repair damaged cells, renewing the scalp.
  • Encourage New Cell Growth: By increasing cell turnover, microneedling helps rejuvenate dormant or weakened hair follicles.
  • Enhance Follicle Resilience: Regular cell regeneration strengthens the follicles, making them more resistant to future damage.

3. Enhance Follicle Function

  • Boost Blood Flow to the Scalp: The microchannels created by microneedling improve circulation, ensuring hair follicles receive adequate oxygen and nutrients.
  • Optimize Nutrient Absorption: Increased blood flow delivers essential vitamins and minerals directly to the hair roots, supporting growth and thickness.
  • Restore Follicle Activity: Weakened or dormant follicles are reactivated through consistent microneedling sessions, leading to the regrowth of hair in previously thinning areas.
  • Support Follicle Anchoring: Improved follicle health ensures hair strands are securely anchored, reducing hair shedding over time.

4. Stimulate Growth Factors

  • Release Essential Growth Factors: Microneedling induces the production of growth factors like Vascular Endothelial Growth Factor (VEGF), which promote the development and longevity of hair follicles.
  • Encourage Follicle Proliferation: Growth factors help increase the number of active hair follicles, which improves overall scalp density.
  • Extend the Hair Growth Cycle: By supporting the anagen (growth) phase of the hair cycle, microneedling contributes to longer, thicker hair strands.
Microneedling for Hair Growth

Who Can Benefit from Microneedling for Hair Growth?

Microneedling scalp treatments are not a one-size-fits-all solution, but they can be highly effective for specific conditions and individuals.

Ideal Candidates

  • Androgenetic Alopecia: Commonly known as male or female pattern baldness, this condition responds well to microneedling due to its ability to stimulate dormant follicles and improve blood flow to affected areas. The prevalence of androgenetic alopecia varies by gender and race, affecting over 50% of older men and 15% of postmenopausal women. 
  • Thinning Hair: Individuals experiencing gradual hair thinning can benefit from improved nutrient delivery to the scalp, which strengthens hair follicles and encourages regrowth.
  • Stress-Induced Hair Loss: Microneedling helps reverse temporary hair loss caused by physical or emotional stress by enhancing scalp health and supporting follicle recovery.
  • Postpartum Hair Loss: Women dealing with hair loss after pregnancy can find relief with microneedling, as it promotes healing and rejuvenation of follicles impacted by hormonal changes. A study on postpartum hair loss revealed that 91.8% of women experienced hair shedding following childbirth, highlighting how common this issue is. Microneedling offers a safe and effective solution for stimulating hair regrowth and restoring confidence during this challenging period.
  • Early-Stage Hair Loss: Those noticing the first signs of hair loss, such as reduced density or minor shedding, can prevent further progression by incorporating microneedling into their scalp care routine.

When Microneedling May Not Be Effective

  • Complete Baldness: Individuals with no active or functional hair follicles may not benefit from microneedling, as the treatment cannot regenerate follicles that are entirely destroyed. For such cases, surgical options like hair transplants might be more appropriate.
  • Scarring Alopecia: Hair loss caused by scarring or permanently damaged follicles often requires specialized medical interventions, such as corticosteroid injections or surgical restoration. Microneedling may not penetrate deeply enough to address issues related to scar tissue.
  • Certain Medical Conditions: Those with active infections, chronic scalp disorders (like severe psoriasis), or clotting issues should consult a medical professional before undergoing microneedling. These conditions can increase the risk of adverse effects, such as infection or poor healing.
  • Autoimmune Disorders: Individuals with autoimmune conditions like lupus or alopecia areata may experience unpredictable results from microneedling. These conditions may require targeted medical treatments to address the underlying causes of hair loss.
  • Severe Skin Sensitivities: People with hypersensitive or overly reactive skin may find microneedling too irritating, potentially causing prolonged redness or discomfort. In such cases, alternative, less invasive scalp treatments may be a better fit.

The Microneedling Process for Hair Growth

Professional microneedling treatments are performed in a controlled clinical setting using advanced equipment, such as dermapens or automated microneedling devices. These tools allow practitioners to achieve greater precision, consistency, and safety compared to at-home methods. 

1. Preparation

The process begins with a thorough cleansing of the scalp to remove oils, dirt, and other impurities that could interfere with the treatment. A numbing agent is applied to minimize discomfort, allowing the patient to remain relaxed during the procedure. The practitioner may assess the scalp’s condition and mark specific areas requiring treatment for targeted microneedling.

2. Microneedling

The practitioner uses a dermapen or automated microneedling device to create controlled micro-injuries in the scalp. These devices are equipped with ultra-fine needles that can be adjusted to penetrate different depths based on the scalp’s thickness and the patient’s needs. The device is gently moved across the scalp in a systematic pattern to ensure even coverage and stimulation of dormant hair follicles.

3. Post-Treatment Care

Following the procedure, the practitioner applies a soothing serum or a topical solution like minoxidil to the treated areas. These products take advantage of the microchannels created by microneedling, which enhances absorption and effectiveness. The practitioner provides aftercare instructions, such as avoiding washing the scalp for 24-48 hours and using mild shampoos in the days following treatment.

Professional sessions typically last 30 to 60 minutes and require multiple treatments spaced a few weeks apart to achieve noticeable hair growth.

Microneedling Combined with Other Treatments

Microneedling is a highly effective standalone scalp treatment, but combining it with complementary therapies significantly enhances its impact on hair growth. These combinations address hair loss from multiple angles, ensuring the scalp and hair follicles receive both the stimulation and nourishment required for optimal regrowth.

Minoxidil

Minoxidil is a widely used topical treatment for hair loss, and its effectiveness is significantly amplified when paired with microneedling.

  • Enhanced Penetration: The microchannels created by microneedling allow minoxidil to penetrate deeper into the scalp, reaching the hair follicles more efficiently.
  • Improved Efficacy: Studies show that the combination of microneedling and minoxidil leads to greater hair density and thickness compared to using minoxidil alone.
  • Targeted Delivery: Microneedling ensures the solution reaches even hard-to-treat areas, such as the hairline or crown, maximizing the overall impact.
  • Consistency is Key: Regular application of minoxidil after microneedling sessions enhances long-term hair regrowth and strengthens existing hair strands.

Platelet-rich plasma (PRP)

PRP therapy involves injecting a patient’s blood plasma, which is rich in growth factors, directly into the scalp. When combined with microneedling, the benefits of PRP are significantly amplified.

  • Accelerated Healing: The growth factors in PRP work synergistically with the micro-injuries created by microneedling, speeding up the healing process and promoting quicker follicle activation.
  • Boosted Follicle Regeneration: PRP enhances the rejuvenation of dormant or weakened hair follicles, increasing the density and volume of hair growth.
  • Personalized Treatment: PRP therapy is tailored to the patient, using their own plasma to minimize the risk of adverse reactions while maximizing effectiveness.
  • Extended Benefits: The combination of PRP and microneedling not only supports hair growth but also improves scalp health by increasing elasticity and reducing inflammation.

Nutritional Supplements

Nutritional deficiencies are often overlooked contributors to hair loss, and addressing these through targeted supplementation complements microneedling.

  • Strengthen Follicles: Nutrients like biotin, zinc, and iron are essential for maintaining strong, healthy hair follicles. Microneedling creates a better environment for these nutrients to work effectively.
  • Support Scalp Health: Vitamins such as vitamin D and omega-3 fatty acids improve scalp hydration and reduce inflammation, ensuring a healthy foundation for microneedling to produce results.
  • Prevent Future Loss: Supplements help address underlying issues that may contribute to ongoing hair thinning, such as hormonal imbalances or poor diet, making them an important part of a multi-faceted approach.
  • Promote Overall Growth: By boosting the body’s ability to repair and regenerate, supplements support the benefits of microneedling and improve the quality of regrowing hair strands.

Potential Side Effects and Risks

Microneedling is a widely recognized and generally safe procedure, but like any medical or cosmetic treatment, it carries potential side effects and risks. 

Common Side Effects

While most individuals tolerate microneedling well, some temporary side effects may occur, especially in the early stages of treatment.

  • Redness and Irritation: The treated area may appear red or feel tender due to the micro-injuries created during the procedure. This reaction typically subsides within 24 to 48 hours.
  • Minor Swelling: Mild swelling may develop around the treated areas as the scalp responds to the procedure. This is a natural part of the healing process and usually resolves quickly.
  • Scalp Sensitivity: The scalp may feel tender or sensitive, particularly when exposed to harsh shampoos or environmental factors like heat and sunlight.
  • Temporary Shedding: Weak or damaged hair strands may shed temporarily as the scalp adjusts to treatment. This shedding is often a precursor to the growth of stronger, healthier hair.
  • Itching or Dryness: Some individuals experience dryness or mild itching as the microchannels heal. Applying a recommended soothing serum can alleviate these symptoms.

How to Minimize Risks

Taking proactive steps before, during, and after treatment can significantly reduce the likelihood of complications:

  • Ensure Proper Preparation: The scalp should be thoroughly cleaned before the procedure to minimize the risk of infection. Any open wounds or active scalp conditions should be addressed before proceeding.
  • Avoid Harsh Products: Refrain from using strong shampoos, styling products, or harsh chemicals for at least 48 hours after treatment to prevent irritation or inflammation.
  • Protect the Scalp from Sun Exposure: Avoid direct sunlight and use a gentle, non-comedogenic sunscreen if necessary, as the scalp will be more sensitive to UV rays post-treatment.
  • Follow Aftercare Instructions: Adhere to all post-treatment guidelines provided by the practitioner, such as keeping the scalp clean and avoiding strenuous physical activities that may lead to excessive sweating.
  • Space Out Treatments: Allow sufficient time between sessions (typically 3-6 weeks) to let the scalp heal and regenerate fully before undergoing the next treatment.
