Derma Roller
A derma roller can be used to promote hair growth by:
Stimulating blood circulation
The micro-injuries created by the roller's needles can increase blood flow to the scalp.
Increasing collagen production
The roller activates the body's natural ability to rebuild collagen and elasticity in the skin.
Stimulating stem cells
The roller can activate stem cells in the hair follicles.
Improving absorption of hair growth products
The micropores created by the roller can make it easier for products like minoxidil and finasteride to penetrate the scalp.
Increasing platelet-derived growth factor
Platelets are essential for wound healing and blood vessel growth, and their derived growth factors can promote cell proliferation in the hair follicles.
Some healthcare professionals recommend using dermarollers alongside other hair loss treatments, such as minoxidil, platelet-rich plasma (PRP), or topical triamcinolone acetonide.
Here are some tips for using a derma roller:
Needle size
The appropriate needle size depends on your goals, but 540 short microneedles at 0.5 mm are commonly recommended.
Side effects
You might experience redness, swelling, mild pain, and bruising, but these usually go away in about five days. If the symptoms worsen or last longer, you should consult a doctor.
Cleaning
After use, you can clean the roller by:
- Rinsing it under warm water
- Soaking it in Dettol or Isopropyl Alcohol for 60 minutes
- Rinsing it again with warm water
- Laying it upside down on a paper towel to air dry
