Hey Sean, sorry that you're not happy with the result so far. Definitely below the standard that we know Dr Rahal has set the bar for hairline/FUE results. Majority of his patients chose him because of the awesome hairline that we are accustomed to see. And you don't have it so far.
Still rooting for you to get it after few more months but those who got great results already had great results by 6 months or so. I always think of youngandy (Hair Restoration Journal for youngandy - 6 months update), who at 3 months was already awesome, as Dr Rahal's standard for FUE/hairline although it's unfair to compare due to a number of variables involved. I still envy his results though.
Goodluck brother.
