You diddnt say it like that once up untill this point, I'll be honest I think your trying to teach granny's to suck eggs boy Bach, as a collective this group of individuals have more years experience under their belts than the amount of years you've been alive, do you really think you need to tell professional hairdressers that hair can be bleached & how? Really?
Can you tell us the science behind what your doing? Because if you can, then I'd be interested to hear what you've got to say
I also think you'd be aware that repeatedly bleaching your mop isn't actually as cool as you think it is
*i'm writing this as if you know nothing about bleach, so excuse it being very obvious*
Sure, but I'm sure you know the scientific changes that are made apparent during bleaching, ofcourse when you bleach hair melanin is dilluted/removed or bleached out if you prefer, the pigment is erased from the hair, the longer its left on the more it's removed but the more damage, but as melanin is a lot more potent than keratin your hair isn't usually destroyed from 1 bleach because it has to eat through melanin before it starts eating at the keratin, so structure isn't usually that much of an issue, the more you bleach it though the more bonds are removed from the hair thus the more it is damaged and weakened
The science I stand by in terms of my hair is facts, such as the hair is made up of many, many disulphur/disulphide bonds and these are broken from mechanical damage, heat damage and from washing even, and from chemical damage, and these bonds are very strong anyway and do take a lot to break a lot of them (to the point you physically see damage such as split ends and/or even coarse dry damaged hair) and when you bleach the hair it is believed 10 or 15% of these are removed/killed/destroyed, but from experience I don't think it's actually possible to put an exact percentage given the times i've done it, but I'll still use it as relevant information, so the more times you bleach the hair the more its damaged, but this is where my experimenting came into the equation, I wasn't satisfied with just believing that, so i pushed the rules and started bleaching my hair every 2-3 weeks, i even did it 3 times a week about 2 times in the duration of my 56 bleachings, and my hair was fine so i kept going, and I counted after about the 10th bleach to see how far I can actually push my hair before it turns stringy and disintegrates, so far it hasn't happened, possibly because I don't leave the bleach on for very long when I overlap, which is kind of self-explanatory *I'm not gonna leave it on for 40 mins each time, THOUGH WHEN I FIRST STARTED DOING IT I WOULD ALWAYS DO MY ROOTS AND ENDS AND PROCESS THEM FULLY, again it didn't destroy many bonds, ofcourse i'm not going to say it destroyed none, because that's kind of impossible even to me, but it had NO visible effect, and under a microscope my hair is very much in tact, even stil(now) my cuticles are not cracked any more than a normal healthy strand, there's hardly any signs of chemical damage under the microscope, and I believe that bleach can only damage hair (that isn't already damaged, if it's damaged to begin with then it's a whole different story/science) if left on for UNDER 10 minutes which is when the reaction from the bleach starts to break down the sulphur in the hair which is where the damage comes from, as long as you don't destroy the hair during the bleach and add in anything lost afterwards you're not losing out on anything when you bleach it again, we have products like Olaplex now which re-link and multiply the bond together stopping them from becoming free thiols so we can push it further, I've had 6 olaplex treatments, but never with my bleach because it's not needed, I'm not changing my routine because it doesn't need to be changed, but i get them anyway to maintain my hair because i can't see the inside of my hair every single day, so that's my 'hair insurance' covered, as long as you add in those broken bonds and the protein and moisture lost during the bleaching and use some cosmetic agents if your hair was damaged afterwards you can repair the hair permanently, especially with olaplex! then you can start again fresh. I'm sure you'll oppose or some of you will oppose what i've said, but think about it, have you honestly tried everything before bleaching hair over and over? probably not, so don't dismiss it until you can prove me wrong PHYSICALLY, science isn't always the truth, science can be changed, science has many times been proven wrong or outdated, unless you can say you've physically done this on MORE THAN one person don't oppose, because I have done it on myself and others and it's never failed me, and I don't think it will, sometimes you've gotta think logic rather than what you've been taught, not everything is right
I learned that the easy way by experimenting and just not listening til I was satisfied with the facts.
