While looking for solutions to combat hair loss, you likely stumbled upon microneedling as a potential solution. But the question here is, "Does it truly work wonders on your scalp?" We bet that some of you might even have questions like:

• What exactly goes into a microneedling procedure?
• What are the risks involved?
• Am I suitable for microneedling?

What is Microneedling?

While the term microneedling might sound intense, the truth is that it is a minimally invasive procedure. Okay, think of a tool with tiny, sterilized needles that dermatologists run gently over your scalp to create micro-punctures. That's the essence of microneedling.

Microneedling is like a wake-up call for your scalp. It creates a micro-environment conducive to stimulating dormant follicles (potentially), promoting new strands' growth.

These needles don't pierce deep into the skin. Instead, they target the upper layers. Sounds counterintuitive, right? Don't worry, this controlled injury actually triggers your body's natural healing response. How? Well, that is something to discuss in the next section.

Does Microneedling Work for Hair Loss or Not?

We told you before that how device like dermpane or dermaroller is used for creating micro-wounds on the scalp, right? Well, what we didn't tell you is that it actually triggers your body's natural wound-healing response. This response unleashes a plethora of benefits for strands health:

Improved blood flow: The micro-injuries caused by the roller are like a beacon. Meaning, they attract increased blood flow to the scalp. This vital surge delivers a much-needed boost of oxygen and nutrients to hair follicles. It often leads to thicker, stronger hair growth.

Stem cell activation: According to dermatologists, microneedling taps into our body's reservoir of stem cells. For those who don't know, these reside within our hair follicles. They play a crucial role in hair regeneration and stimulating them may promote healthier strands.

Growth factor powerhouse: Controlled injury caused by microneedling initiates the release of growth factors. Also called chemical messengers, they help in repairing hair. These include powerhouses like platelet-derived growth factor (PDGF), epidermal growth factor (EGF), and vascular endothelial growth factor (VEGF).

Improved topical treatment absorption: Okay, apart from improving blood circulation, microneedling for hair loss also creates tiny channels on the scalp. Although temporary, these improve the absorption of topical hair loss treatments like minoxidil or vitamin serums.

But one has to be cautious. Increased absorption can also lead to a higher concentration of active ingredients entering your system. In simple words, they increase the chances of side effects. It is highly recommended to follow this combined approach only under the supervision of qualified dermatologists!

Now that you know the science behind microneedling for hair loss. The whole process looks promising, but it's also important to know that research is still ongoing.

Now the next question is, "What is the procedure of using a dermaroller to create tiny holes?" Let's discuss that!

Are There Risks in Using Microneedling for Hair Growth?

Yes, microneedling does show promise for hair regrowth. But that doesn't mean it is without risks as with any procedure that creates wounds:

Infection: Remember we told you how this method involves creating tiny punctures in the scalp (open wounds, essentially)? If proper sterilization techniques aren't followed, there is a chance of infection. This is especially concerning if you perform microneedling at home without proper training or medical-grade devices.

Scarring: Aggressive use of microneedling, particularly when needles are too long or with excessive pressure, can lead to scarring. This is a more significant risk if you have a history of keloid scarring.

Bleeding: Although the needles used in microneedling are tiny, there is a possibility of minor bleeding. This can be especially a problem among men and women taking blood-thinning medications.

Allergic reaction: Some people may experience an allergic reaction to the materials used in microneedling devices. We highly recommend discussing any allergies you have with a dermatologist before undergoing this hair recovery procedure.

Sun sensitivity: Yes, you read it right. After microneedling, your scalp may be more sensitive to the sun. Wear sunscreen with SPF 30 or higher when you're outdoors.

Uneven results: Okay, this is another major problem to consider. If not done properly, dermarollers can lead to uneven results. Meaning, some areas of your scalp may respond better than others. You’re likely to face this risk if you perform microneedling at home without professional guidance.
