Is DHI method better than FUE method for hairline?

As per the information available offhand, DHI is just of the ways of performing FUE done where excision is done with manual forceps and implantation being done with implanters.

Hair grafting/ transplant can be an option for forehead reduction and correcting  asymmetry on your frontal hair line/forelock.I advice you have a FUE; you would get the desired hairline in just one sesssion of dense packing hair transplant.Technique is not important to getting a best result but experience of hair expert is crucial.During the placement of follicular units there will be a mixture of single, double and a few triple grafts, which help to create the soft look of a natural hairline. For the first few lines always go for single grafts, later doubles Triples and others.So that a smooth transition will be there giving undetectable hair transplants.
