According to the search results, derma rollers can be used for hair growth through a process called microneedling. The tiny needles on the roller puncture the scalp, stimulating increased collagen and elastin production and blood circulation to the hair follicles, which enhances nutrient delivery and the absorption of topical treatments. Some benefits of using a derma roller for hair growth include:
Positive:
- Can help stimulate hair growth
- Can increase the absorption of topical solutions such as minoxidil
- Can help massage the scalp
- Can help with collagen production, which prevents hair thinning and supports new hair growth
Negative:
- There is limited evidence of its effectiveness
- It can be difficult to know which size needles to use
- It can have side effects such as redness, irritation, and infection if not used properly
Ingredients or materials:
- Derma rollers are handheld tools used for microneedling, with a small wheel covered in tiny needles
- They are often used with beneficial oils to help penetrate the scalp
It is important to note that most studies investigate the effects of microneedling alongside another therapy, such as minoxidil, and there is not enough research evaluating the use of derma rollers on their own for hair loss. Therefore, it is recommended to use derma rollers in conjunction with other topical products, such as hair loss serums. It is also important to sanitize the derma roller after every use and replace it as soon as signs of wear and tear start appearing.
