According to the search results, derma rollers can be used to stimulate hair growth by triggering healing mechanisms, increasing collagen production, and improving blood flow. Rolling the device across the scalp creates micro-injuries, initiating a healing response and promoting nutrient and oxygen supply to hair follicles. The tiny needles puncture the scalp, stimulating increased collagen and elastin production and blood circulation to the hair follicles. This process enhances nutrient delivery and the absorption of topical treatments. However, there is not enough research evaluating the use of derma rollers on their own for hair loss. Most studies investigate the effects of microneedling alongside another therapy, such as minoxidil. Therefore, it is recommended to use derma rollers alongside other hair loss treatments.
Positive aspects of using derma rollers for hair growth include:
- Derma rollers can be a very affordable option.
- They are easy enough to use at home.
- Derma rollers can help treat hair loss or androgenetic alopecia.
- They can increase the absorption of topical solutions such as minoxidil.
Negative aspects of using derma rollers for hair growth include:
- Not everyone will see results.
- A lack of oxygen-rich blood to the area may not be the problem.
- Improper cleaning might lead to skin infection.
