Hi Kim, even on fine hair you should take the same amount of hair as you would on thicker hair, only use half a head to thicken hair (not add length) and it should be around 100 strands, also the colour is abit off, i probably would of used two shades of blonde in this xi have trained with belle recently and this is my first ever client i used 0.5g nano due to thin hair and did half head i used about 60-70 strands and i couldnt put any more in head due to the thin hair i hope i have done them correctly please advise View attachment 204867 View attachment 204867
