colloquially referred to as "strip harvesting", or Follicular Unit Extraction (FUE), in which follicles are transplanted individually. In FUT, a strip of skin containing many follicular units is extracted from the patient and dissected under a stereoscopic microscope. The site of the strip removal is stitched closed. Once divided into follicular unit grafts, each unit is individually inserted into small recipient sites made by an incision in the bald scalp. In the newer technique, roots are extracted from the donor area and divided into strips for transplantation. The strip, two to three millimeters thick, is isolated and transplanted to the bald scalp. After surgery, a bandage is worn for two days to protect the stitched strip during healing. A small strip scar remains after healing, which can be covered by scalp hair growing over the scar. Scalp reduction Scalp reduction is a surgical procedure in which the hairless region of the scalp of a bald man is reduced. This procedure can reduce the area of the scalp without hair. Regrowth of hair Facial hair Eyebrows Bimatoprost 0.03% has been used to grow eyebrows. Eyelashes The FP receptor agonist, bimatoprost, in the form of an 0.03% ophthalmic solution termed Latisse, is approved by the US Food and Drug Administration to treat hypotrichosis of the eyelashes, in particular to darken and lengthen eyelashes for cosmetic purposes. Also, bimatoprost may be used to treat small or underdeveloped eyelashes. Scalp hair Alternative medication Topical Some popular plant juices sold as hair serum may instead of growing human hair actually inhibit the growth, including 6-gingerol found in ginger. Topical crude onion juice A small 2002 study demonstrated that treatment twice daily for six weeks with crude onion juice from Australian brown onion, re-growth hair on alopecia areata (spot baldness) in 86.9% of the 23 participants. Twice as many flavonols are found in red onion than in yellow onion. Also, non-organic onions might contain pesticides on the peel and in the first scaly leaf. Compounds found in onion that stimulates hair growth: Quercetin: Quercetin (a flavanoid found in vegan food) supplements, has been suggested to treat baldness. A 2012 study demonstrated that alopecia areata could be used to prevent ant treated with quercetin in mice. Quercetin is found in onions primarily in the peel and the first scaly leaf but not in the flesh. Onion bulb size or weight does not appear to be affected by
