It means weather a patient is fit well or not in the protocols of hair transplant surgery, and will the expected outcome will meet his/her needs. Good results can be expected if the patient has
1. Good thick donor hair
2. Pigmented donor hairs
3. Wavy or curly donor hairs, it gives more coverage
4. Quantity wise more donor hairs
Some cases where HT needs evaluation:
Case1: Poor donor area
Suppose if a patient has very poor donor area and at the same time his recipient area is much larger, then in such cases it is wise to understand what his needs are, or else BHT evaluation is must. Out of these in some cases even after planning for BHT the expectations cannot be met, thus it’s wise to drop such cases with proper counseling. Better for such patients are camouflaging tricks
very big recipient area
Case2:
Suppose in recipient area there is extensive scarring or some other pathology then those cases also needs proper evaluation and expected outcome with high failure rates needs to be discussed in detail.
Case3: progressive balding
Suppose a patient of diffuse baldness goes for hair transplant then in future also even after good outcome of hair transplant he might lose his density and might remain unhappy, so these cases also needs to be evaluated and properly guided
Case4: understanding about time duration and progression of HT
Proper understanding and time needed to have the optimum results needs to be discussed and assessed about patients knowledge otherwise patient ends up in soup
