first i bleached the hair for 1/2 hrs and then i bleached more hair for 1 hr and keeped on doing it for 2 hrs 3 hrs 4 hrs 5 hrs and 6 hrs.
mum and i choose to do this because if you put to much bleach in your hair it falls out and turns into jelly and if you leavit in to long it burns your head.
I love yo science project
ReplyDeleteYe it's very interesting and I learnt not to put heaps of bleach in my hair even do i wouldn't put it in anyway
ReplyDeleteI didn't know that Charlie! What an interesting project. What other kinds of chemicals do hair dressers use to colour their hair?
