uh huh. Just like matthew mcconaughey didn't have a hair transplant and grew his hair back with snake oil. All I can tell you is don't be lazy, and read the thread, both this one and the follica patent thread. Wounding works through wound healing, but it needs something to trigger hair growth instead of skin. Think about it, if you get a wound on your arm, does it grow back with hair? No, it doesn't. Add minoxidil during the wound healing process and it might. There is a mild benefit to using microneedling alone, but you need to add certain compounds to push stem cells into forming the right kind of cells during wound healing. Check out
this recent study, and notice how little hair grew back after wounding without the right signals.
