There was a time when gua shas and jade rollers took over everyone’s skincare routines. Then came the kansa wand and now it’s time for LED masks to shine (literally). In the midst of all of these beauty tools, there’s one that has shown promising results but isn’t given enough credit for it–derma rollers

A derma roller, also known as a micro-needling device, is essentially a handheld instrument equipped with tiny needles that create micro-injuries in the skin when rolled across the scalp’s surface. I know it sounds scary. So to help demystify this hair care tool, we spoke to Dr Pooja Chhabra, a  certified Trichologist and Cosmetologist.

Benefits Of Derma Rolling For The Scalp

The science behind derma rollers lies in a process called ‘controlled trauma’ wherein tiny needles penetrate the scalp’s uppermost layer and activate the body’s natural immune response. These micro-injuries actually stimulate the body’s wound-healing processes, leading to several benefits for the scalp.

Explaining this Dr Pooja says, “Derma rolling increases the absorption of topical products, allowing essential hair growth-promoting substances, such as minoxidil or natural oils, to penetrate deeper into the scalp. Micro-injuries trigger the production of collagen and elastin, strengthening the scalp’s structural integrity and improving hair follicle health. Derma rolling also promotes blood circulation in the scalp, providing essential nutrients and oxygen to hair follicles, which is crucial for hair growth.”

Types of Derma Rollers

Derma rollers come in various needle lengths, typically ranging from 0.25mm to 1.5mm. The depth of the derma roller needle determines which layer of skin it targets and the specific issues it can address.

0.25mm to 0.5mm needles are suitable for enhancing product absorption and improving superficial skin texture.

0.5mm to 1.0mm needles can penetrate deeper, stimulating collagen production and treating mild to moderate hair loss.

1.0mm to 1.5mm needles are used for more severe hair loss issues, reaching deeper layers to promote significant collagen synthesis and hair follicle rejuvenation.

Precautions with Derma Roller

Dr Pooja believes that derma rollers are generally safe for most people, but individuals with certain scalp conditions such as active infections, psoriasis or eczema should avoid using derma rollers until their condition is under control. Additionally, those with bleeding disorders or a history of keloid scarring should consult a healthcare professional before using the tool.

Using derma rollers in a proper way is also extremely important because otherwise, it can damage the hair follicles leading to permanent hair loss and scarring.

Sanitise: Always ensure that your derma roller is properly cleaned and sanitised before each use to prevent infection.

Gentle Pressure: Avoid applying excessive pressure while rolling as this can lead to unnecessary irritation.

Frequency: Do not use the derma roller more frequently than recommended, typically once a week, to allow the scalp to heal between sessions.

Combination therapy: Derma rollers alone are not enough if you are looking for hair growth. It needs to be used along with hair growth tonics and serums prescribed by a Trichologist. Make sure you do a consultation and learn the technique of using a derma roller before starting.

Sun Protection: Immediately after derma rolling protect your scalp from direct sun exposure as it can be more sensitive.

Of course, a pressing question is the effectiveness of derma rollers when compared to a regular, age-old oil champi. Putting my doubts to rest, Dr Pooja explained that both derma rollers and champi hair oil improve blood circulation to the scalp. However, derma rolling is effective in promoting the absorption of hair growth-promoting products better. So, combining both methods may yield superior results, but make sure there is enough gap between the two.

Busting Myths

Myth: Derma rolling is painful and causes bleeding.

Reality: Although pain is subjective, derma rolling when done correctly should be relatively painless and shouldn’t cause bleeding. However, it might cause some mild discomfort and a tingling sensation, but it should not be a painful experience.

Dr Pooja believes that derma rolling can be a valuable addition to your hair care routine, but results may vary from person to person. It’s essential to be patient and consistent in your efforts. But if you have concerns about hair loss or scalp health, it’s best to consult a certified trichologist or dermatologist for a thorough evaluation and personalized guidance.
