Even bigger? The answer is not what you might expect, and this video might change your approach to microneedling entirely. Microneedling is a therapy where people use medical-grade needles to create micro-punctures in their scalp skin. Microneedling probably supports hair growth in a number of ways: first, the micro-punctures can enhance the penetration and activation of other topicals, like minoxidil. And secondly, the micro-wounds also activate growth factors that might encourage positive tissue remodeling and hair regrowth in balding scalps. A new study just came out that sheds light on what the best needle length for hair regrowth actually is. In this video, we'll reveal: - What is microneedling (and how it can regrow hair) - The difference between needle lengths and skin penetration depths (and why it's important) - Which of the following groups from the study saw the best results: 0.5mm, 1.0mm, or 1.5mm - Our recommended needle lengths for each microneedling device (roller, automated pen, and stamp) -- VIDEOS REFERENCED: Microneedling For Hair Loss – New Insights!
