In an effort to regrow hair, many people are turning to hair care solutions to help combat hair loss and hair loss. One such solution is the use of a derma roller. This device has a handle on one end and a roller with several small needles on the other end, making it easy to use at home. It involves rolling those needles all over your scalp. It looks scary and painful. Naturally, you may be wondering if using a dermaroller for hair growth is effective and safe. Let’s see if this device, known for tackling skin issues such as acne, can also be effective for those experiencing hair loss.

What is a derma roller?

It is a hand-held device with a drum-like structure covered with small needles, usually 0.2 to 2.5 mm long. “When you roll this device over your skin or scalp, it creates micro-injuries that trigger your body’s natural healing processes. This stimulates collagen and elastin production and increases blood flow,” says the cosmetic surgeon. says Dr. Shweta Mishra.

It also improves the absorption of skin and hair care products, making it a popular tool in aesthetic medicine. Dermarollers were initially introduced for skin rejuvenation, but now they can also help treat acne, acne scars, burn scars, and stretch marks, according to a 2016 study published in the Indian Dermatology Online Journal.

Dermaroller for hair growth: how does it help?

Using a derma roller for hair growth may be effective. It is effective in treating hair loss, according to a 2016 study published in the Indian Dermatology Online Journal. The benefits of using a derma roller for hair growth are:

• The micro-wounds created by the dermaroller on the scalp increase blood flow to the hair follicles, providing them with the nutrients and oxygen they need for hair growth.
• Activates collagen production and strengthens scalp and hair structure.
• Increases penetration of topical treatments such as minoxidil. “This amplifies the effect and encourages dormant hair follicles to re-enter the growth phase,” says the expert. A 2013 study published in the International Journal Of Trichology found that using minoxidil and derma rollers was more effective than using minoxidil alone for hair growth.

“Typically, noticeable improvements such as reduced hair loss and appearance of downy hair can take 8 to 12 weeks with regular use in combination with a proper hair care routine,” says Dr. Mishra. According to a 2020 study published in the journal Biomedical Microdevices, using a derma roller 8 to 10 times can start new hair formation. Hair growth is a gradual process, although significant regrowth can take up to six months. Therefore, patience and consistency are key when using a derma roller to grow hair.

How to choose a derma roller suitable for hair growth?

1. Needle size

When choosing a derma roller for hair growth, needle size is important. “For beginners and people with mild to moderate hair thinning, a 0.5mm roller is best because it penetrates the scalp surface effectively without causing any discomfort,” says the expert. For more severe hair loss or some bald spots, a 1.0 mm roller may be more effective, but care and professional advice are required to avoid scalp damage.

2.Material

Choose a dermaroller with high-quality needles made of titanium or medical-grade stainless steel. Titanium needles are strong and stay sharp for a long time, while stainless steel needles are more hygienic and easier to sterilize. “Both options are safe, but higher quality gives better results and reduces the risk of infection,” Dr. Mishra says.

3. Frequency

If you plan to use your dermaroller frequently, a smaller needle size (such as 0.5 mm) is better because it has a shorter recovery time. “Larger needles, such as 1.0 mm, penetrate deeper and require longer time between sessions (2-3 weeks) as the scalp takes longer to heal,” says the expert.

4. Brand quality

Choose a derma roller from a trusted brand to ensure safety, durability, and effectiveness. High-quality derma rollers are precisely designed to avoid uneven or excessive penetration, reducing the risk of skin damage and irritation.

5. Scalp condition

Before using a dermaroller for hair growth, check the sensitivity and overall health of your scalp. If your scalp is sensitive, start with a smaller needle size and consult a professional for guidance. “People with scalp infections, eczema, or psoriasis should avoid using derma rollers until their dermatologist gives them the green light,” experts say.

What should I apply after using a derma roller for hair growth?

After using a dermaroller, it is important to maximize its effectiveness and prevent irritation. Here are some suitable options that you can choose after using derma roller for hair growth.

• hair growth serum: After using the derma roller for hair growth, immediately apply a serum containing minoxidil or peptides. “The microchannels created by the dermaroller increase the absorption of the dermaroller and stimulate hair growth more effectively,” says the expert.
• sedative: Use soothing products such as aloe vera gel and hyaluronic acid to soothe the scalp, reduce redness, and promote hydration. These also form a protective barrier over sensitive areas.
• antioxidant: Products containing vitamin C or vitamin E protect the scalp from oxidative stress and support the healing process.
• Avoid heavy or irritating products: Immediately after using the hair growth dermaroller, refrain from using hair oils, alcohol-based solutions, or fragranced products. Microchannels can become clogged, leading to inflammation and infection.
• sunscreen for hair: When going out, apply non-comedogenic hair sunscreen to protect your hair from UV damage.

Are there any side effects when using a derma roller for hair growth?

Although dermarolling is generally safe, improper use or poor hygiene can cause side effects such as:

• Redness and inflammation of the scalp: Temporary redness and sensitivity are the most common side effects of micro-injuries caused by needles. This usually subsides within 24 to 48 hours, especially if a smaller needle size is used.
• bleeding: Minor bleeding may occur if the needle is large (>1.0 mm) or if excessive pressure is applied during rolling. “This may be normal for deeper penetration, but should be minimized and controlled,” says the expert.
• infection: If the derma roller or scalp is not properly cleaned before use, bacteria can enter the microscopic wounds and cause an infection. It is important to disinfect your derma roller and keep your scalp clean before and after your treatment.
• Deterioration of the scalp environment: People with scalp diseases such as seborrheic dermatitis should avoid using derma rollers for hair growth purposes unless advised by a professional. It can worsen the condition of your scalp and delay healing.
• allergic reaction: Using harsh or unsuitable products after dermarolling may cause allergic reactions as the scalp is very sensitive after treatment.

Using a dermaroller for hair growth may be effective, but be sure to follow good hygiene practices and use appropriately sized needles. Also, consult a professional before using the device, especially if you have any underlying scalp concerns.
