Benefits of Derma Rollers for Hair Growth

In the quest for thick, luscious hair, individuals are constantly on the lookout for new, effective treatments. One such method that has garnered attention is the use of derma rollers. Originally popular for skin rejuvenation, derma rollers are now being explored for their potential benefits in promoting hair growth.

What is a Derma Roller?

A derma roller is a handheld device equipped with hundreds of tiny needles. When rolled over the skin, these needles create micro-punctures which are intended to stimulate the skin’s natural healing process.

How Does it Promote Hair Growth?

Stimulating Blood Flow

The primary mechanism by which derma rollers aid in hair growth is through the enhancement of blood flow to the scalp. The micro-injuries caused by the needles trigger the body to send more blood to the area, bringing with it nutrients and oxygen that are vital for hair growth.

Increasing Nutrient Absorption

Another benefit of using a derma roller on the scalp is the increase in absorption rates of topical treatments. Products such as minoxidil or essential oils can penetrate deeper into the skin, potentially enhancing their effectiveness.

Collagen Production

The process of micro-needling can also stimulate the production of collagen and elastin in the scalp. These proteins are crucial for maintaining the strength and elasticity of hair follicles.

Using a Derma Roller for Hair Growth

Selection of Needle

Size For hair treatments, needles typically range from 0.5 mm to 1.5 mm in length. The appropriate size depends on the individual’s scalp sensitivity and the specific treatment goals.

Frequency of Use

It is generally recommended to use a derma roller on the scalp once a week to start. This allows the scalp sufficient time to heal between sessions.

Procedure Clean the Scalp:

  • Ensure the scalp is clean and free from product build-up.
  • Disinfect the Roller: Always disinfect the derma roller with an alcohol solution before use. Rolling Technique: Gently roll the device in horizontal, vertical, and diagonal directions across the areas of thinning hair.
  • Apply Topical Treatment: After rolling, apply a hair growth serum or treatment to maximize absorption.


Following treatment, the scalp might feel tender and show slight redness. It’s important to avoid harsh chemicals or heat-styling tools immediately after using a derma roller.

Risks and Considerations

While derma rolling is generally safe, there are potential risks such as infection, irritation, and exacerbation of scalp conditions. It is crucial to consult with a healthcare provider before beginning any new treatment regimen.


Derma rolling represents a promising option for those looking to enhance hair growth naturally. By fostering a healthier scalp environment and improving the efficacy of topical treatments, this method might just be the boost needed to achieve fuller hair. However, as with any treatment, it should be approached with caution and professional guidance.

Incorporating derma rollers into your hair care routine can provide a natural and effective way to stimulate hair growth and improve the overall health of your scalp. Whether you’re dealing with thinning hair or simply looking to boost hair growth, derma rollers offer a non-invasive solution with potentially significant benefits.
