looks good OP
funny thing about these growth aides tho, unless you're quite specific w/ before and after regimen and pics it's hard to track your growth and harder still to confirm the growth you got was specifically from the growth aides.
sounds like you like the results so if you're going to keep using it might be a good idea to start a journal. this wouldn't be just for public purposes (cuz really if you like what you're doing and the results it doesn't matter who isn't convinced) but moreso for your own purposes so you can optimize your results.
i would suggest: documenting your regimen before and after the serum, identifying average growth before and after serum, using this new image as your starting pic, being clear as to whether it's 4 OR 6 wks duration that gave you the 1" growth, for future pics using same angle and hair (air dried? flat ironed? etc)
good luck! hope your growth continues
