Why did bleach end?
The anime has ended for now, but the manga is still going. There is one more arc to finish and it'll be the biggest and longest of all of the acs. The anime will more than likely start up again after the manga is over.
Yes. Not recommended. You could loose all your hair. Take some hair and put it in a glass and add bleach. It will eventually dissolve the hair. There are many ways to bleach your hair without using household bleach. Go to Walmart... Do not get bleach in your eyes. You could end up seeing "nothing" for the rest of your life...
Take half inch parts. Apply the bleach one inch from you scalp. Till the end are close to your desired shade. Than apply bleach to scalp.
