Can we dyed our hair by ourselves?

We can, but I personally prefer a professional since there's more risk of messing it up badly if it's done at home.

It's not difficult, especially if you're just doing an all-over colour. Most store brands are safe. if you're new to it, start with a colour a shade or two from your natural colour - don't try doing any extreme changes

Most store brands are pretty safe. Dont buy & mix up professional shit unless you want to be bald

Better have some one who know how or u be bald with a burnt head
