The Basics of Dermarolling and Hair Loss

What is Dermarolling?


In general, it’s the process of stamping or rolling the skin with a tool that contains metal microneedles. In effect, these needles create micro-wounds to the skin. While this may sound scary, many stressors to the body have positive effects. Think exercise and muscle formation.

Likewise, these tiny acupuncture-like wounds cause the skin to go into repair mode. That is to say, this ‘rebuilding’ is excellent for luscious hair growth and glowing youthful skin.

But first, it’s important to address why your hair is thinning. Because if the root cause of hair loss is not understood, you’re fighting an uphill battle.

Other Names for Dermarolling and Microneedling:

Causes of Female Pattern Baldness

Certainly, we’ve all heard of male pattern baldness, but Alopecia or hair loss affects up to two-thirds of women too. In general, a receding hairline and thinning hair come from hair follicles that shrink and produce shorter thinner hairs or that stop producing hair altogether. 

So what causes hair thinning in women? While not well understood, these are a few of the reasons.

  • Aging
  • Changing hormones
  • Illness
  • Hyperthyroidism 
  • Family history of baldness
  • Prescription medications and/or birth control pills
  • Emotional stress
  • Diet – vitamin and mineral deficiencies

Of course, when you address health and lifestyle issues like stress, diet, and changing hormones, you’ll enhance your dermarolling results. However, it’s important to consult your physician if you suspect underlying health issues.

How Do Derma Rollers Work for Hair Growth?

The benefits of derma rolling for hair growth go beyond the surface of thicker, longer hair. Most notably, it rejuvenates the scalp and causes it to act younger. Additionally, these micro-wounds produce 4 important benefits for hair regrowth, especially when combined with topicals like castor oil.

1. Increases Blood Circulation:

That is to say, your body sends more blood to the area of the tiny wounds which increases blood circulation. Increased blood flow is linked to stopping hair loss. Plus, blood circulation increases nutrients and oxygen to the scalp which in turn promotes hair growth.

2. Activates Collagen and Elastin Production:

Both collagen and elastin help repair damaged hair follicles while promoting continued hair growth and lasting moisture.

These two beauty powerhouses are important in the formation of healthy strong hair and skin. 

3. Stimulates the Production of Stem Cells:

Stem cells have a role in the growth of new hair. Moreover, microneedling stimulates stem cell’s growth and induces activation of key growth factors.

4. Increases Absorption of Topical Serums:

Important to note, hair loss studies show many topical serums increase hair growth. When serums are applied after derma rolling, they absorb deeper and penetrate better into the skin for faster and more effective results.

While a dermaroller used with castor oil for hair loss hasn’t been specifically studied, many women stimulate hair growth with this combination. In addition, other natural hair growth serums are covered toward the end of this article.

The Easiest Way to Use a Dermaroller and Castor Oil for Hair Loss

After you roll your hairline with the dermaroller, apply a very small amount of castor oil to your finger tips and massage into your scalp where you have hair loss. Not only will this fight hair loss but soothe the scalp too.

Next, you’ll want to apply castor oil to these areas twice daily. Once in the morning and again in the evening. Below are tips and tricks for making this work while keeping your hair clean and silky.

Now let’s cover everything you need to know to best use a dermaroller combined with information about castor oil’s benefits for hair growth.

Which Derma Roller Is Best For Hair Regrowth?

Ultimately, the best derma roller for hair loss is one that you’ll use regularly and replace often. 

Although an extra expensive roller isn’t necessary, look for one that comes from a reputable seller that offers a money-back guarantee. 

On the whole, micro needles are made of titanium or stainless steel. Notably, titanium needles are 3-4 times stronger and last longer than stainless steel needles.

However, stainless steel needles are more hygienic and still very strong. Medical professionals, tattoo artists, and acupuncturists all use stainless steel needles. 

These budget-friendly dermarollers are perfect for regrowing hair.


Tip: Always check your needles before use. Never dermaroll with dull or bent needles.

Best Dermapen For Hair Loss

One of the best and most highly recommended microneedling pens is the Dr. Pen Ultima A6. Not only does it have adjustable speeds and needle lengths but it’s wireless too. Plus, it comes with a wire in case your batteries run out of juice.



Ideal Derma Roller Or Dermapen Needle Size

This is probably the most confusing aspect of microneedling for not just hair growth but skin tightening as well.  

Surprisingly your scalp skin is some of the thickest skin on the body and carries more blood than the rest of your skin.

Needle sizes for hair growth range from 0.25mm all the way up to 2.5mm. Because your scalp skin is thicker, micro needling this area is less painful even when needle lengths are longer.

Some argue that you must use at least a 1.5 mm dermaroller for hair growth as you’ll need to penetrate this deep to stimulate hair follicles. 

Most scientific studies use a 1.5mm dermaroller to test hair growth results.

On the other hand, many women, including myself have found similar success with smaller needle sizes of 0.5 mm and 1.0 mm. Plus, topical serums should only penetrate into the top 0.5 mm of the epidermis.

This means you can apply your serum sooner with a microneedle that doesn’t penetrate as deeply. More on this later.

Lastly, beginners may feel comfortable starting with a smaller needle size of .25 mm or 0.5 mm. While it may not produce the fastest results, it’s excellent for product penetration and blood circulation.

Equally important, your needle length determines how often you can dermaroll.

How Often Should You Do Microneedling at Home?

When using 1.5 mm needles, it’s important to wait 7-10 days for the scalp to heal before rolling again. In addition, wait an hour or two before applying topical serums to allow the needle punctures to start repairing.

Generally speaking, microneedling the scalp every 10 days with a 1.5 mm needle length and applying serums 2 times a day shows significant and scientifically proven hair growth results.

However, if a 1.5 mm needle is painful or intimidating, there’s another option.

As mentioned, women still have successful hair growth by using shorter needles. Plus, using smaller needles helps ‘toughen up’ your scalp.

As a matter of fact, one of the benefits of a 0.5 mm needle is its ability to be used more often. So you’re able to shorten the time between rolling sessions.

While you probably don’t want to dermaroll every day, If you use a 0.5 mm needle you can dermaroll 1-2 times a week and still apply topicals twice daily.

So, the frequency of derma rolling will depend on your level of comfort with needle length, how often you prefer to roll, and individual results.

Is Dermarolling Safe for Hair?

By and large, the #1 cause of dermarolling problems come from improper use.

First and foremost, your roller and skin must be clean. As well, always apply serums AFTER rolling your scalp and never BEFORE.

It’s important for topical products like caster oil not to absorb too deeply.

Serums and products aren’t meant to absorb as deep as your dermaroller needles can puncture. Serums should only penetrate into the upper 0.5 mm layer of the epidermis where they don’t cause damage.

While dermaroller punctures close up fairly quickly after rolling, it’s’ still important to wait a while before applying topicals. In other words, the longer your needle length the longer you should wait before applying any products to your skin.

When to Safely Apply Serums Like Castor Oil for Hair Loss After Using a Dermaroller

Needle LengthApplication Time of Serums
1.5 – 2.0 mm1-2 hours after
1.0 mm30 minutes after
0.25 – 0.5 mmImmediately

Be sure to follow the directions below for safe microneedling.

A word of caution, if you have a skin condition like rosacea, acne, dandruff, or any scalp irritations, consult with your primary care physician before microneedling. Likewise, if you have diabetes, hemophilia, or other conditions that inhibit healing, or if you take blood thinners speak with your physician before usage.

How to Safely Use a Dermaroller and Castor Oil for Hair Loss

Microneedling for hair loss at home is simple, inexpensive, safe and effective. 

  1. Start with clean hair and a sanitized roller.
  2. Separate the strands of hair to reveal your scalp or pull hair back tight against your scalp with the opposite hand.
  3. If you’re using a derma roller, use short little strokes so you don’t tangle your hair. (Pulled tangled hair could make hair loss worse.)
  4. Try to create the star pattern shown to the left but most importantly focus on making numerous passes. 8-10 passes in one direction, then lift and change directions.
  5. Always lift the roller before changing rolling directions. 
  6. After using a dermaroller, it’s safe to apply a topical like castor oil for hair growth. See above for the best time to apply.
  7. Always Sanitize your derma roller after using it. 

Personally, I sanitize my dermaroller a second time right before rolling to be on the safe side. Just spritz with 90% rubbing alcohol, air dry, and then roll.

How Long Does a Dermaroller and Castor Oil Take To Work for Hair Loss?

While it can take up to 12 weeks before you start to see thicker hair and new growth, many women find they notice positive results within the first 2 weeks. Especially when you use a dermaroller with a serum like castor oil for hair loss.

Although, 6 months is where you’ll see dramatic differences.

Maybe the hardest part about dermarolling is getting into the habit of rolling once a week and applying a hair growth serum twice a day. That being said, it’s worth the effort to establish the habit. And before you know it, you’ll feel the excitement of seeing new little hairs sprouting up and filling in areas that used to be bare.

How Often Should a Dermaroller be Replaced?

On the whole, a dermaroller’s needles need to be sharp and straight to puncture quickly and come out smoothly. In contrast, dull and/or bent needles do unwanted harm to the scalp’s skin.

For the most part replacement of dermarollers should occur before needles become dull. While some dermatologists recommend replacing dermarollers after a single-use, others advise replacement after 12-15 sessions.

Nevertheless, if you drop your dermaroller and bend any needles from the fall, replacement is immediately necessary. Likewise, if anything feels “off” or different about needle penetration, replace your roller.

What Should I Apply After Dermarolling?

Any hair regrowth serum used with microneedling will work better than using the serum alone. Studies show statistically significant improvements by combining microneedling and growth serums.

Even though there aren’t any studies on the positive effect of using a dermaroller and castor oil for hair loss, there’s plenty of experiential proof.

To be sure, there are both natural and drug based topical serums that effectively stimulate hair growth. Personal preference and experimentation help you decide which works best.

Over-the-Counter Serums for Derma Rolling and Hair Loss:

Although studies prove these over-the-counter topical serums work to improve hair growth, they also come with some harmful side effects.

  • Minoxidil
  • Lipogain
  • Nanoxidil
  • Finasteride

Natural Serums to Improve Hair Growth

Notably, there are many studies that support the use of natural serums for rejuvenating hair loss. Some of the studies compare natural topicals against major drug-based products with encouraging results.

In fact, many natural topicals improve hair loss as much as over-the-counter products. Equally important, these serums don’t come with harmful side effects. Here are a few:

Can You Use Castor Oil After Microneedling?

Once you use your derma roller to stimulate hair growth, it’s safe to apply pure organic castor oil to your scalp. This gentle oil reduces pain and inflammation and is perfect to soothe your scalp and provide nourishment to the hair follicles.  

Castor oil adds moisture and shine to your hair. Even though it may not stimulate hair growth in thinning hair without the accompaniment of micro-needling.

And yet many women have success regrowing hair with castor oil alone, so why not experiment?

Can a Dermaroller and Castor Oil Improve Hair Loss?

Castor oil that comes from the castor bean is full of ricinoleic acid, an omega 9 fatty acid, which reduces pain and inflammation. It’s also a good source of other essential fatty acids, vitamin E, and minerals. All of which promote blood circulation, hydration, and nourishment. 

Although research proves it’s a laxative, anti-inflammatory, and can induce labor, it hasn’t proved to increases hair growth.

In general, dermatologists don’t believe castor oil can make your hair grow. But there’s lots of anecdotal evidence that proves otherwise. In fact, there are plenty of ‘before and after’ pictures of hair growth after using castor oil by itself.

That being said, doctors may argue the improvement is from castor oil preventing hair breakage which in turn causes hair to grow thicker and longer. Either way, longer thicker hair is desirable. 

And while there aren’t any scientific studies that prove castor oil increases hair growth, it offers numerous benefits to the hair.

Castor Oil Hair Benefits: 

  • Hydrates
  • Nourishes
  • Good source of fatty acids, vitamin E, and minerals
  • Antibacterial and anti-inflammatory
  • Maintains moisture
  • Adds shine
  • Smooths flyaways
  • Conditions hair

Your Dermaroller and the Best Castor Oil for Hair Loss

Some castor oil brands are healthier than others. Unfortunately, many inexpensive castor oils are processed using hexane to extract the oil from the castor bean.

Hexane is a synthetic, petroleum-based solvent classified as a neurotoxin by the Centers for Disease Control and Prevention. In contrast, cold-pressed castor oil uses a healthier extraction process. Pure castor oil is thick, odorless, and clear.

It’s important to use castor oil-free of harsh chemicals, dyes, and additives when applying to your scalp. Ultimately, the best castor oil is 100% pure, USDA-certified organic, cold-pressed, and hexane-free. Here are 3 trusted brands:


Fortunately all the brands above are cold-pressed which gives them a shelf life of 5 years. For this reason, it makes sense to save money by buying a larger more economical bottle. On the other hand, if you aren’t sure weather you’ll use it regularly the smaller bottle is good for trying.

How Long Does It Take For a Dermaroller and Castor Oil To Improve Hair Loss?

Ordinarily, I notice hair regrowth within two weeks of applying castor oil to my eyelashes. But for the scalp, women report it takes about 3 months before seeing significant results.

What are the Side Effects of a Dermaroller and Castor Oil for Hair Loss?

Some of the negative side effects of dermarolling are pain at the site of rolling, redness, dryness, and flaking skin. In a sense, dermarolling is like giving yourself a sunburn. Although, over time many women notice a reduction in pain.

Because of the injuries microneedling creates, it’s better to roll at night to give your scalp some time to calm down. In addition, castor oil will soothe a tender scalp, help it heal, and then absorb into the skin overnight.

The most common side effect of castor oil comes from it being a thick oil. Since no one wants to add greasy hair to hair loss, you’ll need to wash your hair soon after applying.

However, if you have an extremely dry scalp or dry coarse hair, applying a little castor oil to your scalp at night won’t necessarily cause your hair to be greasy in the morning.

That being said, if you don’t have a dry scalp, there are a few tricks to keep hair silky and clean while still reaping the benefits of castor oil.

First, it’s important to use the tiniest amount of oil on your fingertips. It doesn’t take much castor oil to absorb into your scalp for positive results.

Second, castor oil can be thinned by mixing it with lighter oils that are healthy for your scalp too. Both coconut and jojoba are thinner oils that prevent hair loss and promote hair thickness.

But even better is to add essential oils like rosemary and peppermint to castor oil. After all, both have been proven to thicken hair and improve growth.

Final Thoughts: Dermaroller and Castor Oil for Hair Loss

Without a doubt, thinning and receding hairlines are a bummer. Maybe you expected to get wrinkles and put on a few pounds as you got older. But hair loss? That was something men had to worry about, not you.

Yet there’s hope. In essence you have nothing to lose and everything to gain by experimenting with microneedling for hair growth.

As shown above, dermarolling and applying topical serums afterwards stimulates new thicker hair. Why suffer the embarrassment of hair loss when you can easily and inexpensively turn the clock back and enjoy a full head of hair again.
