community If the main mechanism of microneedling is an increase in bloodflow to the scalp, shouldn't we be pursuing other actions which increase bloodflow? Sauna, cold showers, high dosage fish oil, hard cardio, heme-iron(red meats), HAND STANDS, foods high in NO (arugula), ginger, increased water consumption
Microneedling stimulates hair growth through stem cell activation during wound healing, not just increased blood flow. Other methods like showers or supplements don't replicate this effect.
