Dermarollers are devices that may stimulate hair growth. These products have microneedles that prick the skin and may help hair growth by increasing blood flow to the scalp.

A quick look at 6 of the best dermarollers for hair growth

This article describes what dermarollers are, how they work, and where to purchase these products online.

Microneedling is a type of treatment that uses hundreds of small needles that cause micro-injuries to the skin and scalp.

Some people may use this treatment to reduce the appearance of fine lines and wrinkles, and the American Academy of Dermatology (AAD) notes that it may also help encourage hair growth.

However, the AAD warns that microneedling may worsen some conditions, and a person should contact a dermatologist for advice before purchasing any products.

Dermarollers work by causing micro-injuries to the skin without significantly damaging the skin barrier. These micro-injuries heal quickly, leading to stimulation of collagen and elastin fiber production, which can improve the appearance of the skin.

These products may also help improve how medication reaches the skin, as micro-injuries allow medications to penetrate the skin barrier more easily.

People should always follow the manufacturer’s instructions when using a dermaroller. However, some general tips include:

  • sterilizing the dermaroller
  • cleaning the scalp and ensuring it is dry
  • using the device on the scalp horizontally, vertically, and diagonally
  • applying any medication that a dermatologist recommends, such as minoxidil, on the scalp.
  • sterilizing the dermaroller and leaving it to dry
  • placing the dermaroller into its container.

There is some evidence that dermarollers can benefit hair growth. Most studies investigate the effects of microneedling alongside another therapy, such as minoxidil, and there is not enough research evaluating the use of dermarollers on their own for hair loss.

A 2021 review found that microneedling may be more effective at increasing hair growth than minoxidil. However, using minoxidil and microneedling together was more effective than microneedling alone.

Another review suggests that some healthcare professionals may recommend using dermarollers alongside minoxidil or other hair loss treatments, such as platelet-rich plasma (PRP) or topical triamcinolone acetonide.

When choosing a dermaroller, consider the following factors, such as:

  • Dermatologist recommendations: A dermatologist may recommend certain dermarollers to suit an individual’s requirements, such as ones with different needle sizes. However, some dermatologists may not recommend dermarollers.
  • Features: Some dermarollers have features to make them easier to use, such as an anti-slip design for stability and control.
  • Instructions: It is a good idea to purchase dermarollers that come with clear instructions on how to use the device.

Below are some dermarollers a person may purchase. However, people should only purchase one if their dermatologist recommends it.

People concerned about hair thinning or hair loss might consider contacting a board certified dermatologist.

The AAD states that dermatologists will ask questions about hair loss or hair thinning, test the strength of the remaining hair, and look at the scalp and nails to determine the cause of the hair loss. Dermatologists may also order tests that may help diagnose why a person’s hair is thinning.

Dermatologists can work with a person to determine which treatments are necessary. They may recommend at-home treatments, prescription medications, or procedures that require healthcare professionals, such as corticosteroid injections or hair transplants.
