Hair thinning is an issue where people are willing to try different approaches such as taking food supplements, seeking professional hair treatments. Among all the investigated tools, the derma roller is one of the most popular ones that has recently received a lot of attention. Originally used to treat skin issues, the derma roller is being utilized to encourage hair growth as well. But does it really work? In this article I will explain what derma roller is, how it works for hair growth, the evidence that supports it and if it is worth trying for hair loss. If you’re interested in this trending tool and you are thinking if it is something for you, read on to know more.
What is a Derma Roller?
A derma roller is a tool which looks like a roller and is made from stainless steel with numerous, very fine needles. Originally developed for skin treatment, it’s intended for executing a procedure known as micro-needling. Micro-needling is done by rolling the device over the skin and creating a microscopic zone of injury to stimulate the fibroblasts to produce collagen, increase blood flow and penetration of topically applied substances. The derma roller used on the scalp is believed to wake up dormant hair follicles in an effort to encourage hair growth.
How Does a Derma Roller Work for Hair Growth?
The theory behind using a derma roller for hair growth is based on the same principles as micro-needling for skincare. Here’s how it’s believed to work:
Increased Blood Circulation:
The tiny punctures made by the derma roller stimulate blood flow to the area, supplying hair follicles with oxygen and nutrients essential for growth.
Enhanced Product Absorption:
When paired with hair growth serums, a derma roller allows active ingredients to penetrate deeper into the scalp, making treatments more effective.
Stimulation of Collagen Production:
Just as it does on the skin, micro-needling stimulates collagen production on the scalp, which may help strengthen hair follicles and improve hair quality.
Activation of Dormant Follicles:
Some studies suggest that the micro-injuries caused by the derma roller may “wake up” dormant follicles, leading to hair regrowth in areas experiencing thinning.
Does Science Back Up the Claims?
Some research and clinical studies offer favorable outcomes of the usage of the derma roller for hair regrowth. A paper in the International Journal of Trichology noted that people who used a derma roller alongside the minoxidil saw better hair regrowth than the people who only used the minoxidil.
However, it is important to have these results in mind knowing that derma rolling is not a magic bullet for everyone. As hair loss is a function of genetics, hormonal and lifestyles, each person’s response to it may be different. You should consult a hair doctor in Delhi or a trichologist to know if derma roller is feasible for your type of hair loss concerns.
How to Use a Derma Roller for Hair Growth?
If you decide to give a derma roller a try, following a proper technique is crucial to avoid damage or irritation. Here’s a step-by-step guide on how to use it safely:
Choose the Right Needle Size:
For hair growth, a needle size of 0.5 mm to 1.5 mm is generally recommended. Smaller needles may not penetrate deeply enough to be effective, while larger needles could cause pain or scalp injury.
Clean Your Scalp:
Start with a clean, dry scalp. Washing your hair beforehand is important to avoid introducing dirt or oils into the micro-wounds created by the derma roller.
Sanitize the Derma Roller:
Clean the roller with alcohol or a disinfectant to ensure it’s free of any bacteria.
Use the Roller on the Scalp:
Roll the derma roller over the scalp in different directions—horizontal, vertical, and diagonal. Apply light pressure to avoid pain or injury. Spend around 2-3 minutes on each area.
Apply a Hair Growth Serum:
After rolling, apply a serum or topical solution (such as minoxidil or other hair growth products) to the scalp. The microchannels created by the roller can help improve absorption and effectiveness.
Sanitize and Store the Roller:
After each use, clean the derma roller and store it safely.
It’s generally recommended to use a derma roller for hair growth 1-2 times per week. Overuse can lead to irritation or even damage to the scalp, so it’s important not to overdo it.
Pros and Cons of Using a Derma Roller for Hair Growth
Like any treatment, using a derma roller for hair growth has its benefits and drawbacks. Let’s take a look:
Pros
Cost-Effective: Compared to other hair growth treatments, a derma roller is relatively affordable.
Enhances Product Efficacy: The microchannels created can improve the absorption of hair growth serums, making them more effective.
Stimulates Blood Flow: Increased circulation can improve scalp health, potentially contributing to hair regrowth.
Cons
Risk of Irritation: If used incorrectly or too frequently, a derma roller can cause scalp irritation, redness, and even scarring.
Results May Vary: The effectiveness of a derma roller depends on the individual. It may not work as well for people with advanced hair loss or certain medical conditions.
Requires Patience: Results from derma rolling are not immediate. Consistent use over several months is typically required to see any noticeable changes.
Are There Better Alternatives?
A derma roller is helpful, but it is not for everyone. If the hair fall is more, then they should opt for professional treatments such as PRP therapy, laser therapy or a hair transplant. One should consult a hair doctor in Delhi in order to get to know which treatment can be beneficial in his case.
Side Effects and Precautions
Though derma rolling is generally safe, there are some side effects and precautions to keep in mind:
Infection Risk: When not cleaned appropriately, the derma roller can spread bacteria to the scalp which causes infections.
Pain or Discomfort: It is unlikely that users will suffer any irritation, although those with a sensitive scalp may feel a slight discomfort.
Possible Scalp Injury: Excessive use of the derma roller may harm the scalp and hair follicles, therefore increasing hair loss.
If you have a specific skin condition on the scalp, such as eczema or psoriasis, derma rolling is not advised because it will only worsen your condition.
Consulting a Hair Doctor in Delhi is a Great Idea
If you are still on the fence about using a derma roller, the first thing that you should do is to seek the opinion of a hair expert. The best hair doctor in Delhi can diagnose the problem with the scalp and the pattern of hair loss and suggest the right course of action which may include derma roller, PRP or other modern treatments. They can also advise you on how to use derma roller properly so that you avoid damaging your skin yet have the best results.
Conclusion: Is a Derma Roller for Hair Growth Worth Trying?
The derma roller can be a valuable tool for those looking to stimulate hair growth in the early stages of hair loss. With proper use, it may help improve blood circulation, enhance the effectiveness of hair serums, and potentially awaken dormant follicles. However, it’s essential to have realistic expectations and to remember that the results can vary from person to person.
For those looking for more reliable solutions, consulting with a hair doctor in Delhi is recommended. A professional can offer personalized advice and suggest alternative treatments tailored to your specific needs.
