Having healthy hair is something that almost everybody is after. However, maintaining healthy hair can be challenging with daily exposure to environmental pollutants, hair styling tools, and harsh hair products. Hair loss, thinning, and lack of growth are common hair problems that people face. One solution that has gained popularity is using a derma roller for hair growth. This article explores the science behind using a derma roller and how it can help achieve healthy hair and scalp.
What is a Derma Roller?
A derma roller, also known as a microneedle roller, is a handheld device that has tiny needles on a roller. It is primarily used in skincare to increase the absorption of skincare products and stimulate collagen production. However, it has gained popularity in the haircare industry due to its potential to improve hair growth and thickness.
The Science Behind Derma RollingÂ
When the derma roller is rolled on the scalp, it creates micro-injuries that trigger the body’s natural healing process. The body responds to these micro-injuries by improving blood flow, which brings nutrients and oxygen to the scalp. The increased blood flow also helps to remove toxins that could be inhibiting hair growth. As the scalp heals, new hair follicles are produced, resulting in thicker and healthier hair.
Derma Rolling and Hair Product Absorption
In addition to stimulating hair growth, using a derma roller also increases the absorption of hair products. When the scalp is rolled with a derma roller, it creates tiny channels that allow hair products to penetrate deeper into the scalp. This increased absorption can help to nourish the hair and scalp, promoting healthy hair growth.
How to Use a Derma Roller?
Using a derma roller is a simple process. First, wash your hair and scalp with a gentle shampoo and pat it dry. Next, you should part your hair into sections and roll the derma roller back and forth over each area for 2–3 minutes. You should apply gentle pressure, ensuring the needles penetrate the scalp without causing any discomfort. After using the derma roller, you can apply your preferred hair products, such as hair oil or serum, to your scalp to enhance hair growth.
Derma Roller and Scalp Health
Using a derma roller can also promote scalp health. The increased blood flow to the scalp helps to nourish the hair follicles and improve the overall health of the scalp. It can also help remove dead skin cells, excess oil, and other debris that could clog the hair follicles and prevent hair growth. Additionally, using a derma roller can help to reduce scalp inflammation, which can contribute to hair loss.
Safety Precautions When Using a Derma Roller
While using a derma roller is generally safe, there are a few precautions that you should take to ensure your safety. First, always use a clean derma roller to avoid introducing bacteria to the scalp. You should also avoid using a derma roller on irritated or inflamed skin. You should consult a dermatologist before using a derma roller if you have any scalp conditions, such as eczema or psoriasis.
In conclusion, using a derma roller for hair growth is a safe and effective way to achieve healthy hair and scalp. The science behind derma rolling shows that it can stimulate hair growth, increase the absorption of hair products, and promote scalp health. By following the recommended safety precautions and incorporating derma rolling into your hair care routine, you can achieve thicker, healthier hair.
