How long can I use my comb and hair brush before I change new ones?

Use them as long as you want! Just wash them with your shampoo regularly...once a week....or once every 2 weeks.

hiDon't do it!

I did it, I went from dark down to blonde, it killed my hair

I had to get it cut really short, my hair started to fall out!

and the funny thing is, hairdressers will do it, why? because they want your money.

I wish mine said to me, "Don't do it, it will burn your hair and make it fall out" Instead she said "of course I do it, you'll look great"

I thought I looked great until I saw myself in pictures, my eyebrows were still black!

I looked fake, so now I'm back to natural dark brown but it took 8 months and chopping my hair off to get back to this
