Robotic hair transplant procedure is a logical advance in the technology of Follicular Unit Extraction (FUE). Follicular Unit Extraction is a harvesting procedure where hair is removed directly from the donor region of the scalp as individual, naturally-occurring groups of 1-4 hairs. The technique consists of two main steps: 1) Separation of the follicular units from the surrounding skin, and 2) Extraction (removal) of the follicular units from the scalp.
In General, the more minimally invasive a hair restoration procedure, the less pain that is often involved with no line scar produced. You can wear your hair short after this restoration procedure.
