Did you mean Microneedle?

GlossaryMicroneedle

Microneedles are tiny, minimally invasive needles that are used in various dermatological and cosmetic procedures, including hair restoration treatments. They create micro-injuries in the scalp, which can stimulate the body's natural healing processes and enhance the absorption of topical treatments, such as minoxidil. This technique is relevant to hair loss as it may promote hair growth by increasing blood flow and delivering therapeutic agents more effectively to hair follicles. Key distinguishing characteristics include their small size, typically ranging from 0.1 to 1.5 millimeters in length, and their ability to induce a controlled inflammatory response without causing significant pain or damage to the skin.
