Derma-rolling, Micro-needling and Hair Loss

Summary

In this episode of The Hair Loss Show, Dr. Russell Knudsen and Dr. Vikram Jayaprakash discuss derma rolling as a treatment for hair loss. They explain how the device works by creating small punctures in the scalp to stimulate blood flow and growth factors, which can encourage hair growth. The doctors discuss the ideal needle depth for effectiveness (1-1.5 mm), the risks of overuse, and the potential for temporary shedding. While derma rolling can complement other treatments like Minoxidil and Laser Therapy, it is best used cautiously, with focus on thinning areas rather than completely bald patches.

Takeaways

• 😀 Derma rolling involves using a device with small needles to create controlled superficial injuries to the scalp, stimulating hair growth through increased blood flow and growth factors.
• 😀 The procedure is based on the concept of controlled injury, similar to other therapies like laser resurfacing, which also promote healing and hair growth.
• 😀 Derma rollers come in different needle lengths, typically ranging from 0.5mm to 1.5mm, with longer needles causing more injury and potentially more growth factors but also increasing the risk of hair follicle damage.
• 😀 The ideal needle length for hair regrowth is between 1mm and 1.5mm, targeting the 'Bulge' area where hair stem cells reside, which is crucial for stimulating hair growth.
• 😀 For skin rejuvenation, a shallower needle depth may be sufficient, but for hair growth, deeper penetration is necessary to reach the stem cells in the Bulge area.
• 😀 There is a risk of temporary hair shedding if the Derma roller damages hair follicles or induces excessive inflammation, highlighting the importance of careful technique and appropriate needle depth.
• 😀 Derma rolling should not be overdone. It is recommended to use the device 2-3 times per week to avoid excessive inflammation and potential damage to the scalp.
• 😀 While Derma rolling is not the first treatment option, it can be an effective add-on to other therapies like Minoxidil or laser therapy for stimulating hair growth.
• 😀 Using a clean Derma roller and avoiding excessive bleeding is essential to prevent infections and further scalp damage.
• 😀 Derma rolling is most effective on areas with early signs of hair thinning (miniaturization) rather than completely bald spots, as it cannot regrow hair where follicles are no longer present.
• 😀 For best results, it is recommended to wet the hair before using the Derma roller to prevent the hair from clumping and to make the procedure easier by rolling in one direction (e.g., forward and backward).

Q & A

What is Derma Rolling and how does it work for hair loss treatment?

Derma Rolling involves using a handheld device with small needles that roll across the scalp, creating micro-injuries. This process stimulates the body's healing response, increasing blood flow and growth factors in the area, which encourages hair follicles to grow.

What is the ideal needle depth for hair loss treatment using a Derma Roller?

For hair loss treatment, the ideal needle depth is between 1mm to 1.5mm. This range targets the stem cells in the Bulge area of the hair follicle, which are crucial for hair growth.

Can Derma Rolling cause permanent damage to the hair follicles?

While Derma Rolling is generally safe, improper use or excessive depth may cause damage to the hair follicles, potentially leading to temporary shedding or long-term follicle damage. It’s important to follow the recommended depth and frequency to avoid this risk.

How often should you use a Derma Roller for hair loss?

Derma Rolling should be done no more than 2-3 times a week to allow the skin time to heal between sessions. Overuse can lead to excessive inflammation, which may hinder the healing process.

What are the risks associated with using a Derma Roller?

The main risks include temporary hair shedding, potential damage to hair follicles, and excessive bleeding if the treatment is not done correctly. Also, using too deep of a needle or rolling too frequently can lead to inflammation or further injury.

How do the needles in a Derma Roller help with hair regrowth?

The needles create controlled micro-injuries in the scalp, which trigger the body’s healing process. This leads to increased blood flow and the release of growth factors, which in turn stimulates hair follicles to grow new hair.

Is Derma Rolling effective for regrowing hair in completely bald areas?

No, Derma Rolling is most effective in areas with thinning or miniaturized hair follicles. It is not effective for completely bald patches, as the hair follicles may no longer be active or healthy enough for regeneration.

Should you combine Derma Rolling with other treatments for hair loss?

Yes, Derma Rolling can be used as an add-on to other treatments like Minoxidil and Laser Therapy. It works synergistically with these treatments to stimulate hair growth, but should not be the first treatment choice on its own.

How can you reduce the risk of injury while using a Derma Roller?

To minimize injury, use the roller gently and avoid excessive pressure. Wet your hair before treatment to help separate strands, and ensure you are using a clean roller to prevent infection. It’s also crucial to follow the recommended needle depth and frequency of use.

Is Derma Rolling considered a highly invasive treatment for hair loss?

No, Derma Rolling is considered a mildly invasive treatment. While it does puncture the skin, it does not cause major harm if used correctly. However, it is still important to use it carefully to avoid complications like excessive bleeding or follicle damage.
