Confused about bleach on the scalp/off the scalp

Hi pinkies!
   So I have been lurking here for awhile, coveting all of your pink fabulousness, and I have been reading through the bleaching tutorials and FAQ, and also watching bleaching tutorials on youtube, however I am slightly confused. Here, in the awesome bleaching FAQ the professional colorist seems to really stress the safety issue of not getting off the scalp bleach (which I'm assuming is the most common type) on your scalp, and even says getting it on your scalp can cause chemical damage that can make your hair never grow back in places.

Thats REALLY scarry,

I have been blonde before, from a very dark brown (level 2) natural hair, and the colorist put the bleach on my hair first, and then all over my roots because the heat from your scalp causes the bleach on the roots she said to develop faster, resulting in something she referred to as "hot roots". She said  it would look odd if she did the roots at the same time because the roots would be lighter than the rest of my hair. She never said anything about the reason being that  my hair may potentially fall out from getting bleach on my scalp!  All of the videos I see (on youtube) show it being done similarly to the experience I had (some by colorists at salons and some by novices) , where the person just applies the bleach mixture all over the hair first and then to the roots (and scalp) last, for the least amount of time.

Im pretty certain all of these people in the videos arent using "on the scalp" bleach. To be honest I don't think I have ever even seen that type of bleach  in the sallys where I go. Have any of you used "on the scalp" bleach?  If so, does it work just as well? Also,  if you  just use regular (off the scalp)  bleach for your roots, do you just leave it  for a shorter time where it touches your scalp? Has it ever made any of your hair grow thinner ,or not at all in certain places? I'm also wondering if any of you use two different kinds of bleach just to be safe, like one for the roots/scalp,  and one for the rest? I'd love to hear some experiences, and to know what you prefer. I really want my roots to match the rest of my head, not be darker. (or lighter for that matter)

*also as a side note, I have dyed red hair now, can I just bleach over this?, or would that be too damaging and cause breakage?

"On the scalp" refers to the level of peroxide used mixed with the bleach. It's best to keep 40vol off of the scalp because of how strong it is. 20vol is fine, but it's still best to do your roots last because the heat from both the bleach and your scalp make the bleach work faster. And your roots getting melted is the worst.

And yes, you can bleach your red hair, but it depends on how healthy your hair is first, obviously.

i use 40 volume on the scalp all the time, but i have unusually sturdy skin. some people respond badly to even 20 or 10 volume.

bleaches made for off-the-scalp use can also be stronger even discounting the peroxide...the powder itself can have more ammonia or the equivalent.

neither is more "regular" than the other, they're just made for different purposes...overall lightening vs highligts, flashes, that sort of thing.

if you want to be the most gentle on your hair, first use a dye remover like colorfix or color oops, then bleach with an oil bleach...that's a setup where you have an oil, an accelerator which is a powder, and then you add peroxide. wella wellite is good, cheap, and effective.
redken levitation is even better but it's hard to find with no license.

the oil buffers your hair and lessens the risk of damage...i have level 2 hair and i get it up to level 8 or 9 with no breakage or mushiness, especially when i use wella in depth right after bleaching...another cheapo sallys item that works wonders.

anything you do to your hair is unhealthy...
its obvious bleach is bad for it.
it completely strips your hair of pigment and dries it out.
thats why its called bleach.
If your hair is in good condition there will be minimal damage though

I guess I've been completely doing it wrong this whole time. Still, I've never had anything happen other than yeah, it stings a little. I do use specifically-for-sensitive-skin developer, so maybe that helps?

Just so you know, red is pretty hard to bleach out - when I first went pink I had it done professionally, and it had to be bleached twice because I had dyed dark red hair to begin with. It sounds gross, but it helps if your hair is oily/not clean when you go to bleach it because the oil will help protect your roots from frying.

i use Quick Blue and 40 volume developer abotu once a month. i have never lost any hair or had and part of my scalp not grow hair. i have fairly short hair, so usually the bleach is right on my scalp. Quick blue DOES say it can be used for on or off scalp (although i think it recomends, like the other commenters said, a lower level {20, for example} volume developer). You can get Quick Blue and different levels of developer at Sally's

PS i love your icon!!

*shrug* I've used 40 vol on my scalp without ill effect. Different folks will have different reactions though, but I've never heard of permanently burning hair off.
