Well, to be honest I saw no noticeable improvement to the length of my hair (hence why I didn't take a photo after a month), and although I had completely used up the hair treatment mask, I still had plenty of the leave in treatment left, so I continued to use that for another month to see if it made any noticeable difference.
So after just over 2 months, here is the growth.
So overall, I'd say about an inch growth, which isn't bad, but not too impressive...
(and yes I know my hair is pink in the second photo, but this dying process does no damage to the hair, hence not affecting the length).
I still have a bottle and a half of the leave in treatment, so I intend to keep using this until I run out.
I am also going to be taking 'hair skin and nails' vitamins and 'folic acid' suppliments daily, so hopefully this will help further improvements!
