If you've been wanting to microneedling your scalp and hair, you may have questions. Some of these questions could be "Does microneedling work for hair growth?" or even just simply "How does microneedling «before and after» work?". These are valid questions, and it's normal to wonder about them.

Microneedling is no longer used just for skin renewal. It's becoming recognized as a promising treatment for hair thinning and healthy hair development.

If you've been curious about microneedling for hair loss, scalp results, or hair restoration, this article will explain all you need to know.

From choosing the right device to proper technique and aftercare, we'll explain why microneedling for hair loss at home is becoming popular and how to perform it safely and efficiently for the most outstanding results.

How Microneedling Works for Hair Growth

Let's first start off with the basics. Microneedling promotes hair growth by causing regulated micro-injuries on the scalp's surface. These micro-wounds trigger the body's healing response, increasing collagen formation and blood flow to hair follicles. Increased blood flow provides more oxygen and nutrients to the follicles, creating a solid basis for hair regeneration.

Additionally, microneedling improves the absorption of topical treatments such as minoxidil, peptides, and hair growth serum. This implies that whichever substance you use after microneedling will penetrate deeper, increasing its effectiveness.

Microneedling for hair loss has been found in several medical trials to enhance hair density and thickness when paired with therapies such as minoxidil. Growing data shows that microneedling scalp treatments might awaken dormant follicles and aid hair maintenance and regrowth.

If you've seen microneedling scalp before and after photos, the transformation can be dramatic when treatments are consistent and properly performed.

Choosing the Right Microneedling Device

While both derma rollers and derma pens have gained popularity, knowing the differences between them can really help you pick the right one for your needs. Let's break it down for you:

Derma Roller vs. Derma Pen

Derma Roller:

Derma rollers are more affordable and widely available, making them an easy entry point for many beginners. They can quickly cover larger areas like the scalp, which is great when treating thinning hair across broad sections.

However, rollers move across the skin's surface horizontally, which can create more tearing or microtrauma if not used carefully.

Derma Pen:

Derma pens, on the other hand, offer vertical precision. Instead of dragging across the skin, the pen's needles move straight up and down, minimizing unnecessary trauma. Pens also feature adjustable needle depths, letting you tailor treatments to different parts of the scalp.

For these reasons, most experts recommend microneedling pens for more controlled, effective treatments, especially when targeting sensitive or patchy areas.

Recommended Needle Length for Scalp Treatments

Microneedling scalp depth is also another important factor. When microneedling the scalp, here's what to follow:

  • 0.5 mm to 1.0 mm is generally recommended for improving serum absorption and addressing mild to moderate hair thinning.
  • 1.0 mm to 1.5 mm is better suited for advanced hair loss, where deeper stimulation is needed.

That being said, needles longer than 1.0 mm should only be used by trained professionals, as deeper penetration increases the risk of injury or improper healing.

Safety and Quality Considerations

When investing in a device, make sure to prioritize safety and quality. Choose devices with surgical-grade stainless steel or titanium needles for maximum durability and hygiene.

It's really crucial to make sure you sanitize your microneedling tools before each use, even if you're doing it at home. If you don't, you could face risks like infections, discomfort, and disappointing results from using subpar equipment or not properly sterilizing it.

In all, choosing the proper device is the first step toward safe and effective microneedling for hair regeneration.

Preparing Your Scalp for Microneedling

Proper preparation is crucial before starting microneedling scalp treatments. Follow these essential steps:

#1. Clean the Scalp

Make sure to wash your scalp really well to get rid of oils, dirt, and any styling products. Opt for a gentle, sulfate-free cleanser to keep irritation at bay. And don't forget, your scalp should be completely dry before you move on to the next step!

#2. Disinfect the Device

Before each use, soak your microneedling pen or roller head in 70% isopropyl alcohol for at least 10 minutes. This step is essential to prevent bacteria from entering the microchannels created during treatment.

#3. Numbing Cream

If you have a sensitive scalp or if you're using needles longer than 1.0 mm, it might be a good idea to apply a numbing cream about 20 to 30 minutes before your treatment. Just be sure to wash it off completely before you get started!

Being properly prepared ensures that you minimize risks and maximize the benefits of microneedling for hair regrowth.

Step-by-Step Guide to Microneedling the Scalp

Now that we've prepared you for your microneedling treatment, let's go over the process. Here's a simple step-by-step guide to microneedling your scalp for hair growth:

  • Step 1. Divide your scalp into small sections for easier coverage.
  • Step 2. Gently stamp (or roll if using a roller) the device in vertical, horizontal, and diagonal directions.
  • Step 3. Do not apply excessive pressure. Simply let the needles do the work.
  • Step 4. Focus a little extra on thinning or balding areas, but ensure even coverage across the scalp.
  • Step 5. A full session should take approximately 5 to 10 minutes, depending on the size of the treatment area.

Microneedling should feel slightly uncomfortable but never painful. Always try to avoid causing bleeding.

Post-Treatment Care

The post-treatment care portion of this process is extremely important. Following microneedling for hair growth, it's essential to follow these aftercare steps:

  • To prevent damage to the microchannels, do not wash your hair for 12 to 24 hours after the session.
  • After the waiting period, you can apply recommended hair growth serums like minoxidil, peptides, or growth factor-enriched treatments to boost results.
  • Keep your scalp moisturized with a lightweight, non-comedogenic hydrating serum.
  • Wear a cap or apply a light sunscreen to your scalp to protect it from direct sun exposure for several days.

In all, good aftercare promotes speedier healing and improves overall outcomes.

Frequency of Microneedling for Hair Growth

If you're planning on getting started, you may be wondering how often you should microneedle for hair growth. The frequency depends on the needle length you are using:

  • 0.25 mm to 0.5 mm Needles: Every 2 weeks.
  • 1.0 mm Needles: Once every 3 to 4 weeks.
  • 1.5 mm Needles: Once every 4 to 6 weeks.

Microneedling with larger needles needs more recovery time between treatments to avoid overloading your scalp.

That said, visible results usually show after 8 to 12 weeks of frequent sessions. Early signs include less hair shedding, a fuller look at the roots, and a generally better scalp condition.

As for the cartridges, we recommend using cartridges with more needles: the 24-pin or the 36-pin cartridge.

Risks and Precautions

While microneedling for hair loss is safe when done correctly, there are a few precautions to take to avoid the possible risks, such as:

  • Always use a clean device since using unsterilized equipment can lead to infection.
  • Be gentle with your scalp; too much pressure might harm it and cause it to take longer to recover.
  • Follow the proper treatment session timeline; overuse might cause inflammation in the scalp and halt growth.
  • People with scalp infections, eczema, psoriasis, or open wounds should avoid microneedling until the skin is completely healed. If you're hesitant, visit a dermatologist before getting started.

That said, there's no need to worry. To ensure safe and effective results from your microneedling scalp sessions, always follow the recommended needle depth and frequency guidelines.
