Hair loss and thinning is a major concern for many people. While traditional hair loss treatments like medications can work for some, they aren't always effective or have unwanted side effects. A derma rolling is a more natural approach to potentially stimulating hair growth. Keep reading to learn if derma rolling really works to promote hair growth.

Does a derma roller work for hair growth?
Yes, using a derma roller can help encourage hair growth for some people. A derma roller is a small device with many tiny needles that cause micro-injuries to the scalp when rolled over it. This controlled injury triggers the body's wound healing response, leading to an increase in blood flow and growth factors to the follicles.
How it works:
Derma rolling is thought to aid hair growth through the following mechanisms:
- Increased blood flow - The micro-injuries from derma rolling cause capillaries and small blood vessels in the scalp to dilate, improving circulation and delivery of nutrients to hair follicles.
- Growth factors - Growth factors like collagen, elastin and certain proteins are released by the body to repair the tiny "wounds." These promote hair follicle health and new hair growth.
- Loosening of collagen - The needle injuries cause fibroblasts to produce more collagen, making the scalp tissue more pliable and allowing hair follicles to enter the optimal growth phase more easily.
Clinical studies have found derma rolling to enhance hair growth by extending the hair follicle growth (anagen) phase by weeks or months compared to not using a derma roller. The best results typically require a minimum of 4 to 6 months of consistent derma rolling 1-2 times per week to see benefits.
Who sees best results?
Derma rolling seems to work best for those experiencing gradual thinning from aging or mild to moderate genetic hair loss (androgenetic alopecia). It may stimulate dormant (telogen) follicles to re-enter the growth phase. Those with severe hair loss may still see some regrowth, but prescription treatments work better. Regular scalp massages after derma rolling can further improve results.
Tips for use:
When using a derma roller at home, it's important to follow these tips:
- Only use a derma roller with 0.25-1mm needles, as longer needles can cause damage.
- Cleanse and dry the scalp thoroughly before each use.
- Roll the device evenly in different directions over the entire scalp.
- Do not apply too much pressure to avoid overly damaging the scalp.
- Use the roller 1-2 times per week, allowing 2-3 days between sessions for healing.
- Wash the roller with soap and water after each use.
- Consider applying a serum with peptides or hydrolized collagen after to aid the healing process.
While results vary, derma rolling shows promise as a natural treatment option to potentially stimulate dormant hair follicles and encourage new hair growth when done consistently over time. It provides a low-cost, low-risk addition to a hair loss regimen for those seeking a more holistic approach.
