Excellent
• Reasonable expectations
• Good to Excellent hair quality and donor density
• Low potential for further hair loss
• Good scalp laxity (FUT)
• Motivated to use medical therapy
• Females: specific area of hair loss (vs generalized)

Donor Hair Assessment: Objective
• Hair loss progresses throughout one’s life, and
• as such the permanent donor hair has to be assessed in a logical and scientific manner in order to ‘future proof’ the surgery.

Factors to consider when making recipient sites
• Recipient Sites determine the individual placement of the grafts
• Sites determine the overall aesthetic result of the hair transplant
o Direction
o Angle
o Depth
o Orientation
o Geometry
o Density

Recipient Site density
• Dense packing - probably 40 grafts/cm2 or above
• Studies showing undoubted significant reduced yield beyond 50 grafts

2 Methods of Donor Harvesting
• Follicular Unit Extraction (FUE)
– Manual or Mechanised
– Automated Robot-Assisted
• Strip Technique (FUT)

Follicular Unit Excision (FUE)
• Method of harvesting the donor
• Use 0.7 – 1.2 mm manual or automated punches to
extract individual follicular unit grafts
• Usually requires a full shave of the donor area
• Limited shaving or clipping for smaller numbers

Strip FUT Harvesting Method
• Narrow, but long strip or skin graft excised from a dense central area– Should be able to completely
cover with hair
• Strip is then microscopically dissected into individual grafts
• Usually needs larger set up and skilled technical staff
