Hair loss is a common problem that affects many people, and it can be a significant source of stress and anxiety. Losing one's hair can lead to a loss of confidence, as it can significantly affect our overall well-being. 

But you're not alone; the concern of hair loss is a common issue. Research estimates suggest that approximately 50% of men and 40% of women will experience some form of hair loss by the time they reach the age of 50. 

Even so, dealing with the emotional impact of hair loss can be challenging, especially if it happens suddenly or at a young age. For many people, their hair is an essential part of their identity, and losing it can be devastating.

Because of this, many traditional and modern or both combined have been tried and tested to grow hair back on one's scalp. Hair transplants, medication, and other treatments. 

In the world of hair growth strategies and inventions, microneedling has recently started to take center stage. This technique, which is non-invasive and more commonly linked to skincare, has been demonstrated to effectively boost both the health of the scalp and the growth of hair.

There are many questions when it comes to microneedling on the scalp. How to do it? Am I using the correct cartridge?

Worry not; this blog will help you uncover the basics you should know about microneedling on the scalp for hair regrowth, so you can try this at home!

What is Microneedling?

For those who don't know, microneedling is a dermatological procedure that involves creating microscopic punctures in the skin using tiny, sterile needles. This process instigates the body's natural healing response, stimulating collagen production and increasing the absorption of topical treatments. 

These tiny holes are so small that they don't hurt much and heal quickly, but they are just enough to trick your body into a "repair mode." 

Just like your body quickly works to heal a small cut or bruise, it also speeds up to fix these little punctures. The healing includes improving blood flow and making more collagen, a type of protein. This protein is key to making your skin stronger and healthier.

How Does Microneedling Work on The Scalp?

Well, when the body is in "repair mode," it doesn't only produce more collagen but also stimulates the growth of new cells, including hair cells. The increased blood flow brings more nutrients to the hair roots, making your hair healthier and stronger. 

By microneedling on your scalp, you're encouraging your body to create a better environment for hair growth. The treatment also enhances the absorption of topical treatments, if you're using any, meaning those products can better reach the areas they need to work on.

Steps on How to Microneedle on the Scalp? 

Choose the Correct Microneedling Cartridge for on The Scalp

The first step in the microneedling process is choosing the correct cartridge. For example, Dr. Pen's microneedling pen models each have a range of cartridges to complement different treatments. There are options from 11-pin to 48-pin to choose from.

For microneedling on the scalp, it is advised to use a cartridge with more needles: the 24-pin or the 36-pin cartridge. This is to suit the skin of the scalp.

For the needle length, it should ideally be between 0.5mm to 1.5mm for scalp treatment. A size of 0.5mm can enhance the absorption of topical treatments if you are doing some regular hair growth serum treatment. 

In comparison, 1.0mm to 1.5mm can be used if you intend to stimulate more deep scalp layers, promoting hair growth with the microneedling treatment.


Before starting the procedure, cleaning the scalp thoroughly is crucial to avoid infection. Numbing cream can be applied before microneedling if you have concerns about how it might be painful.

The Microneedling on the Scalp Process


A session should last 10-20 minutes, depending on the scalp area you're treating.

In this treatment, you can also apply either hyaluronic acid or hair restoration serum to enhance the effectiveness of the microneedling treatment.

To start the microneedling process, you can move the microneedling device across your scalp in a grid-like pattern for the procedure. Do not apply excessive pressure, and ensure you cover all areas experiencing hair thinning. 

There are also some important do's and don'ts you can follow in doing microneedling on the scalp, such as:

  1. Do keep it clean: Always make sure your device and area of work are clean to avoid cross-contamination.
  2. Do take it slow: Start with shorter needle lengths and increase as your scalp becomes accustomed to the procedure.
  3. Don't overdo it: Avoid putting excessive pressure. Excessive pressure can lead to irritation, inflammation, and even damage to the scalp. 
  4. Don't ignore pain or discomfort: While microneedling can cause slight discomfort, extreme pain or prolonged irritation isn't normal. Consult a professional if you experience these symptoms.

After microneedling on the scalp

It's advisable to avoid washing your hair for at least 4 hours following the treatment. 

It's also essential to avoid using scalp products with artificial scents for at least a few days post-treatment. 

You may notice your scalp peeling off a few days post-treatment, similar to when your skin peels after a mild sunburn. This is an expected response as the surface layer of your scalp is renewing itself. 

You might also experience some discomfort or tenderness on your scalp. This is perfectly normal, considering the numerous micro-injuries caused by microneedling.

Should you notice any persistent inflammation in a specific area, make sure to sanitise the area thoroughly with an antiseptic like a betadine before bedtime.

Do not expose your freshly treated scalp to direct sunlight, which can cause unwanted reactions. It's similar to how our skin becomes more susceptible to sunburn when it's just been exfoliated. 

Wear a hat or head scarf to help to protect your scalp during this healing time.

Please do not engage in intense physical activity, as it can cause the scalp to sweat. In the healing period, the scalp is prone to infection from bacteria and dirt.  

Lastly, sleeping on a clean pillowcase can also help you prevent potential infections.

Essential Aftercare

It's important to remember that there is no one-size-fits-all solution to hair loss.

Additional supporting care can also be a helpful factor in the success of microneedling on the scalp.

For example, using an LED Light Therapy device regularly on the scalp to fasten the healing process while increasing the stimulation of hair growth.

Some successful cases also include the application of Minoxidil regularly on the scalp.

Expecting results from microneedling on the scalp

Sticking to a routine can be difficult, but consistency really is key when it comes to microneedling your scalp. Usually suggest starting out with one session per week for the first month, before stepping up to twice a week in the second month.

After the initial two months, you can slow down a bit, and maintain your results by microneedling just once a month.

Now, remember, everyone is different and results can vary. Yet, many people start noticing a positive change in their hair regrowth from about three to six months into the treatment.

This suggested schedule is designed to ensure your scalp heals completely after each session, and so you can accurately track your progress.

But remember, this is just a general guide. Your healthcare professional is your best resource for personalized advice to address your specific hair loss needs. We strongly recommend checking in with them for the best results.
