Assuming normal laxity of the scalp and average density, we recommend 2 or at most 3 full length strip procedures in a person's lifetime.When to go for a HT, is majorly dependant on the patient's awareness level more then anything else.If the person is aware what all is involved in the HT and what are the possible worst case scenarios for the future, and he is confident to tackle them as and when they arise, then I would say he qualifies a major condition for getting a HT.Age, extent of hairloss, familial predisposition to extensive hairloss and the current speed of hairfall are other issues to keep in mind.
