Hair loss is a common concern affecting millions of people worldwide. Whether caused by genetics, aging, or medical conditions, losing hair can impact self-esteem and confidence. As a result, many people are constantly searching for effective treatments to promote hair regrowth. One such treatment that has gained popularity in recent years is microneedling. But does microneedling in Islamabad for hair growth really work? Let’s explore the science, benefits, and what you can expect from this procedure.
What Is Microneedling?
Microneedling is a minimally invasive cosmetic procedure that involves using a device with fine needles to create tiny micro-injuries in the skin. This process stimulates the body’s natural healing response, increasing collagen production and enhancing blood circulation. Originally used for skin rejuvenation, microneedling has now become a popular treatment for hair loss as well.
How Does Microneedling Promote Hair Growth?
Microneedling helps promote hair growth through several mechanisms:
-
Increases Blood Circulation: The tiny punctures improve blood flow to hair follicles, ensuring they receive more oxygen and nutrients essential for growth.
-
Boosts Collagen Production: Collagen is crucial for healthy skin and hair follicles, supporting hair regrowth and strengthening hair structure.
-
Activates Growth Factors: Microneedling triggers the release of growth factors such as platelet-derived growth factor (PDGF) and vascular endothelial growth factor (VEGF), which promote hair follicle regeneration.
-
Reduces Scalp Inflammation: Inflammation can hinder hair growth, and microneedling helps reduce inflammation by encouraging the body’s natural healing processes.
-
Enhances Absorption of Topical Treatments: When combined with hair growth serums like minoxidil or platelet-rich plasma (PRP), microneedling improves their penetration and effectiveness.
Scientific Evidence Supporting Microneedling for Hair Growth
Several studies have demonstrated the effectiveness of microneedling in treating hair loss:
-
A 2013 Study: Published in the International Journal of Trichology, this study found that participants who combined microneedling with minoxidil experienced significantly more hair regrowth compared to those using minoxidil alone.
-
A 2018 Study: Researchers observed that microneedling alone showed promising results in increasing hair density in individuals with androgenetic alopecia (pattern baldness).
-
A 2021 Review: Published in Dermatologic Surgery, this review analyzed multiple clinical studies and concluded that microneedling is an effective and safe treatment for various forms of hair loss.
Who Can Benefit from Microneedling for Hair Growth?
Microneedling can be beneficial for individuals experiencing:
-
Androgenetic Alopecia (Male & Female Pattern Baldness)
-
Alopecia Areata (Autoimmune Hair Loss Condition)
-
Thinning Hair Due to Aging
-
Hair Loss from Poor Circulation or Nutrient Deficiency
However, individuals with active scalp infections, keloid-prone skin, or certain medical conditions should consult a dermatologist before undergoing the treatment.
What to Expect During a Microneedling Session
A professional microneedling session for hair growth typically follows these steps:
-
Consultation: Your provider assesses your scalp, hair loss condition, and discusses treatment expectations.
-
Cleansing: The scalp is cleaned thoroughly to remove any dirt or oil.
-
Application of Numbing Cream: To minimize discomfort, a topical numbing agent is applied and left on for 20-30 minutes.
-
Microneedling Procedure: The practitioner uses a derma roller or a microneedling pen to create micro-punctures in the scalp.
-
Application of Hair Growth Serum (Optional): Some professionals apply minoxidil or PRP immediately after microneedling for enhanced absorption.
-
Post-Treatment Care: The scalp may appear red and slightly swollen, similar to a mild sunburn. It is advised to avoid sun exposure, harsh shampoos, and excessive touching of the scalp for a few days.
How Many Sessions Are Needed for Visible Results?
Microneedling is not a one-time treatment; multiple sessions are required for optimal results. Generally:
-
Mild Hair Loss: 3-4 sessions, spaced 4-6 weeks apart.
-
Moderate to Severe Hair Loss: 6-8 sessions over several months.
-
Maintenance Sessions: Every 3-6 months to sustain hair growth results.
Most individuals start noticing visible hair regrowth after 3-6 months of consistent treatment.
At-Home vs. Professional Microneedling: Which Is Better?
While at-home derma rollers are available for self-use, they are less effective than professional treatments. Here’s why:
-
Needle Depth: Professional microneedling devices penetrate deeper into the scalp (1.5–2.5mm) compared to at-home rollers (0.25–0.5mm), leading to better results.
-
Safety & Hygiene: DIY microneedling carries a higher risk of infection and improper technique, which may cause scalp damage.
-
Enhanced Results: Dermatologists may combine microneedling with PRP or other growth factors, enhancing the treatment’s effectiveness.
Potential Side Effects and Risks
Microneedling is generally safe, but some temporary side effects include:
-
Redness & Irritation
-
Mild Swelling
-
Tenderness
-
Minimal Bleeding (Usually in deeper treatments)
Serious side effects are rare but may include infections if proper hygiene is not maintained.
Conclusion: Is Microneedling Effective for Hair Growth?
Yes, microneedling has been scientifically proven to promote hair growth by stimulating the scalp’s natural healing processes, increasing blood circulation, and enhancing the absorption of hair growth products. While results vary based on the severity of hair loss, many individuals have reported noticeable improvements after undergoing multiple sessions.
For best results, it’s recommended to undergo microneedling under the supervision of a dermatologist or professional trichologist. If you’re considering microneedling for hair growth, consult a specialist to determine whether this treatment is suitable for your hair loss condition.
