Hair transplant consultations are full of jargon: grafts, follicular units, transection, shock loss. This glossary defines the 30 terms DFW patients actually encounter, in plain English, so you can read a quote line by line and ask sharper questions before spending anything.
The vocabulary matters because the industry quotes, plans, and markets in these terms. A clinic that prices “per graft” is using the standard unit, a follicular unit holding 1 to 4 hairs. A clinic quoting “per hair” can make the same procedure sound cheaper. Knowing that transection means damaged grafts, that shock loss is usually temporary, and that density is measured in follicular units per square centimeter turns a confusing sales conversation into one you can evaluate. The definitions below are grouped the way you will meet them: the procedures themselves, the anatomy involved, the hair loss terms that describe your starting point, and the recovery vocabulary that describes the year after surgery. Definitions follow the usage in the ISHRS patient glossary, the professional body for hair restoration surgeons.
Procedure terms
FUE (follicular unit excision). The dominant modern technique. Individual follicular units are removed from the donor area with a small punch tool and implanted into thinning areas, leaving tiny dot scars instead of a line. Read the full breakdown on our guide to FUE hair transplants in DFW.
FUT (follicular unit transplantation). The strip method. A thin band of scalp is removed from the back of the head and dissected under microscopes into individual grafts. It yields large graft counts efficiently but leaves a linear scar.
DHI (direct hair implantation). An FUE variant where grafts are loaded into a pen-shaped implanter and placed directly, controlling depth and angle in one motion. Compared in detail on our DHI hair transplant in DFW page.
Implanter pen. The spring-loaded device used in DHI that holds a graft inside a hollow needle and releases it at a set depth.
Punch. The circular cutting tool, typically 0.7 to 1.0 millimeters across, used to score around each follicular unit in FUE.
Megasession. A single sitting of roughly 3,000 or more grafts. Demands a strong donor area and a large surgical team.
Hairline design. The planning step where the surgeon draws the new front edge, balancing your age, face shape, and future loss. Single-hair grafts go at the border for softness.
Scalp micropigmentation (SMP). Not a transplant. Medical tattooing that replicates the look of shaved stubble or adds visual density between thinning hair.
PRP (platelet-rich plasma). An injectable treatment made from your own concentrated platelets, used to slow thinning or support grafts after surgery.
Anatomy and grafting terms
Follicular unit. The natural bundle hair grows in: 1 to 4 follicles sharing one exit point, averaging about 2.2 to 2.4 hairs per unit.
Graft. One harvested follicular unit, ready for implantation. The standard pricing and planning unit. In Dallas-Fort Worth, FUE typically runs $3 to $8 per graft; see real session math in our guide to hair transplant cost in Dallas.
Donor area. The DHT-resistant band of hair at the back and sides of the head that supplies all grafts. Finite: most men can spare roughly 6,000 to 8,000 grafts over a lifetime.
Recipient area. The thinning or bald zone receiving grafts.
Recipient sites. The tiny incisions made in the recipient area, whose depth, angle, and direction determine how natural the result grows.
Density. Follicular units per square centimeter. Native density runs around 80 to 100; transplants typically rebuild 35 to 50, which reads as full coverage to the eye.
Hair caliber. The thickness of each hair shaft. Coarser hair covers more scalp per graft.
Transection. Damage to a follicle during extraction, cutting it so it cannot survive. Skilled FUE teams keep transection rates in the low single digits; high rates waste your donor supply invisibly.
Graft survival rate. The percentage of transplanted grafts that take root and grow, typically quoted at 90 to 95 percent in experienced hands.
Laxity. How loose the scalp is. Relevant mainly to FUT, since a tight scalp limits strip width.
Hair loss terms
Androgenetic alopecia. Male or female pattern hair loss, the genetic, hormone-driven condition behind about 95 percent of male cases.
DHT (dihydrotestosterone). The hormone, converted from testosterone, that shrinks genetically sensitive follicles and drives pattern baldness.
Miniaturization. The shrinking process DHT causes: each growth cycle produces a finer, shorter hair until the follicle stops producing visible hair.
Norwood scale. The 7-stage grading system for male pattern baldness, from no loss to the horseshoe pattern. Your stage anchors graft estimates; grade yourself on our Norwood scale quiz.
Telogen effluvium. Temporary diffuse shedding triggered by illness, stress, or rapid weight loss. Not pattern baldness, and usually reversible.
Alopecia areata. An autoimmune condition causing smooth round bald patches. Treated medically, not surgically.
Finasteride and minoxidil. The two FDA-approved medications for pattern loss. Finasteride lowers DHT; minoxidil stimulates follicles directly.
Recovery and results terms
Shock loss. Temporary shedding of native or transplanted hair in the weeks after surgery, caused by the trauma of the procedure. Alarming, common, and usually recovers within a few months.
Shedding phase. The expected drop of transplanted hairs at weeks 2 to 8. The follicles stay rooted and regrow; the shed is part of the cycle, not graft failure.
Ugly duckling phase. The awkward stretch around months 2 to 4 when shed grafts have not yet regrown and the recipient area can look worse than before surgery.
Crusting. The small scabs that form at each graft site in week one. They flake off with gentle washing per post-op instructions.
Maturation. The 12 to 18 month process of new hairs thickening and gaining length. Judging a transplant before month 12 undersells the final result.
Frequently asked questions
What is the difference between a graft and a hair?
A graft is a follicular unit containing 1 to 4 hairs, averaging about 2.3. A 2,000-graft session moves roughly 4,400 to 4,800 hairs. Always compare clinic quotes in grafts, the standard unit.
What is a good transection rate?
Experienced FUE teams keep transection under about 5 percent. Ask the clinic directly; a team that does not track its rate is telling you something.
Is shock loss permanent?
Almost never. Native hair shed from surgical trauma typically regrows within 3 to 4 months. Permanent shock loss is rare and usually involves hair that was already miniaturizing.
