What is Derma Roller?

 

A Derma Roller is a tool consisting of small cylindrical rollers equipped with fine needles ranging in length from 0.5 to 3 mm. This tool has been used since the 1990s, when scientists discovered that massaging the outer layer of the skin stimulates the production of collagen, which helps the skin repair itself. In addition to its benefits for the skin, collagen is also a support for hair follicles, which makes experts believe that this process enhances hair density and growth. For example, clinical studies related to androgenetic alopecia showed significant positive results after using the derma roller to treat hair loss over a period of 12 weeks, at a rate of once a week, until 2015.

When do the results of using the derma roller for hair appear?

 

The derma roller is one of the effective tools for stimulating hair growth and increasing its density. The results of its use usually appear within a period ranging from 8 to 10 weeks. However, this period may vary based on individual factors, in addition to the coincidence of using the derma roller with other topical treatments for hair growth.

**Factors affecting the results of the derma roller for hair**

There are several factors that affect the results of using the derma roller on hair, the most prominent of which are:

- Age

What is the appropriate needle size for hair growth?

 

It is usually recommended to start using small microneedles (0.5 mm) to promote hair growth, then move to larger sizes if necessary. It is preferable to consult a specialist doctor before using needles of 1.5 mm or larger, as the risk of scarring increases significantly. In general, it is useful to talk to your doctor before considering using a derma roller, especially if you have a history of acne or eczema, or if you are taking blood thinners or any other medications, or if you suffer from health conditions that affect healing such as diabetes.

What is the role of Derma Roller after hair transplantation?

 

The importance of the derma roller is closely related to collagen, which makes up 25% to 35% of the total protein content in the body. Although it is found in small quantities in the hair follicles themselves, collagen is also found around these follicles, where it supports the growth of new hair. The derma roller works to enhance the production of collagen in the scalp, which supports the hair growth phase within the follicles. It also contributes to improving blood flow. When the derma roller is used to massage the scalp, small wounds are created in the outer layer of the skin, which stimulates the skin to send more blood to that area to speed up the healing process. Therefore, it is highly recommended to apply a moisturizing lotion after using the derma roller on the scalp. In recent years, research has shown that the regulation of stem cells is linked to the proliferation and quality of hair follicles. The microneedles in the derma roller stimulate the production of these stem cells, which contributes to enhancing hair growth and density. If you are unsure how to use the derma roller at home after a hair transplant, many beauty clinics offer similar services using microneedling.

**Wound Healing**When using derma roller needles on the scalp, micro-injuries are created that stimulate the body to respond to the wound healing process. This response activates the growth factors necessary for wound healing and hair follicle regeneration.

**Stimulates Blood Circulation**Derma roller needles help enhance blood circulation in the treated area, as increased blood flow, known as vasodilation, improves the supply of oxygen and nutrients needed for hair follicle growth, which contributes to better hair growth.

**Increased Collagen and Elastin Production**Collagen and elastin are vital proteins for skin health, as they contribute to increasing the elasticity and hydration of the dermis, the area that contains hair follicles. Therefore, increasing the production of these two proteins provides a suitable environment for healthy hair follicle growth.

**Increased Absorption of Topical Medications**The micro-injuries caused by using derma roller needles help improve the absorption of topical medications, which enhances their effectiveness.

How Often Should I Use Derma Roller for Hair?

 

The number of times you should use a derma roller for hair depends on the purpose of your treatment and your doctor’s recommendations. In general, it is best to use a derma roller once to twice a week. However, overuse should be avoided to avoid scalp irritation or hair damage.

What is the best derma roller size for hair?

 

The best derma roller size for hair depends on the purpose of your treatment:

**Derma roller size for hair from 0.15 to 0.25 mm:**The derma roller size from 0.15 to 0.25 mm is considered a low size and suitable for beginners, especially when using a topical hair growth treatment. Using a derma roller of this size helps to enhance the absorption of the treatment and increase its effectiveness. Also, the shorter needles reduce the possibility of feeling pain compared to longer needles, making the experience more comfortable for the user.

**Derma Roller Size for Hair Between 0.5 to 1.5mm:**If your goal is to stimulate hair growth, using a 1.5mm derma roller can be effective, as it can better penetrate the skin and stimulate blood circulation in the scalp. However, beginners should be careful when using larger sizes, as this can increase the likelihood of pain or irritation. Therefore, it is always important to consult a doctor before using any derma roller device to ensure it is suitable for your individual condition and to ensure its safe use.

**Derma Roller Size 1.5mm and Above**: This size is considered too large and is not suitable for home use. If used incorrectly, it can cause damage to the skin, such as irritation or injury. Therefore, sizes larger than 1.5mm are best reserved for trained professionals who know how to use them safely and effectively. However, users should always consult a doctor or expert before using any derma roller device, to ensure it is suitable for their individual conditionResponsive and without causing any problems.

**How ​​to choose the right type?**

 

There are several types of derma rollers that differ according to the size of the needles and the manufacturing materials. The needles can be made of various materials, which requires maintaining a high level of hygiene when using the derma roller. It is necessary to wash them with soap and sterilize them with an alcohol solution after each use.

**Types of derma rollers:**

**Titanium derma roller:**Titanium is a strong, lightweight, and corrosion-resistant metal, making it a better choice than stainless steel for small needles of 0.2-0.3 mm. Titanium needles rarely lose their sharpness over time, allowing the derma roller to be used for a long time without the need to change them. However, the hardness of titanium makes sharpening the needles difficult. Additionally, titanium is not a naturally sterile metal, so extra effort must be taken to keep it clean, sterile, and rust-free.

**Metal Derma Roller**Stainless steel is a healthier choice due to its resistance to corrosion, thanks to its chromium content and the protective layer it forms on the outer surface, which protects it from stains and rust. Stainless steel needles are also sharper than titanium needles, although titanium is a softer metal. Over time, the needles tend to become sharper. The stainless steel type should only be used once or twice, just as surgical blades are used only once for the same reason. Thanks to their sharpness and precision, stainless steel microneedles cause fewer tears in the skin and scalp.

**. Derma Roller ZGTS:**The Derma Roller ZGTS is available in several sizes including 0.2, 0.25, 0.3, 0.5, 0.75, 1, 1.5, 2, and 2.5 mm.
