Re: Possible way to protect hair from conventional peroxide damage
This is most interesting, IMO.
Chelants prevent oxidative damage to hair. Surprise? Not to me. The flavonoids in honey lightening recipe ingredients are chelants too.
"[0001] The application is a continuation of International application PCT/US02/08482 (Case CM2517M2) filed on Mar. 19, 2002.
Oxidative treatment of hair with reduced hair damage
Agent: The Procter & Gamble Company Intellectual Property Division - Cincinnati, OH, US
[0022] .... now been surprisingly found that chelants have excellent damage inhibiting properties. ....
[0058] .... chelants could efficiently prevent oxidative hair damage when formulated in level higher than previously mentioned in the literature or formulated in commercial compositions.
Without Pretreatment
[0168] .... chelants .... are preferably formulated directly in the oxidizing compositions applied on hair (e.g. oxidative dye compositions or bleaches).
[0174] .... chelants can also be applied to hair as a pre-treatment. The pretreatment composition .... applied immediately before the oxidizing composition or after a longer period of time."

The chelants used to prevent bleach damage are either added to the bleach itself when it is processed or used as a pretreatment. This is what I understood, after I read the other research.
Re: Possible way to protect hair from conventional peroxide damage
More from the same source, short version
"[0009] ....The oxidizing agents used for bleaching and oxidative dyeing damage hair to some extent. The mechanism by which damage is caused to the hair fibers is not perfectly understood."
[0010] .... most dyeing or bleaching compositions .... sold with .... conditioner .... applied on hair after the bleaching or dyeing composition has been rinsed off. Examples of conditioning agents are silicones, cationic surfactants and cationic polymers. .... conditioners cannot prevent successive chemical treatments causing premature hair breakage.... conditioners do not bring the hair back to its initial condition but merely conceal .... damage under a protective layer of .... conditioning agent, .... only results in an improved feel of the hair."

They should read Professor Molan's honey research on hydrogen peroxide, IMO.
“…. harmful effects of hydrogen peroxide …. further reduced because honey sequesters and inactivates the free iron which catalyses the formation of oxygen free radicals produced by hydrogen peroxide .... and its antioxidant components help to mop up oxygen free radicals ....”
http://www.worldwidewounds.com/2001/...cal-agent.html
And this predates the patent application.
“Protection by the Flavonoids Myricetin, Quercetin, and Rutin Against Hydrogen Peroxide-Induced DNA Damage ….
Exposure to 50 μM H2O2 for 30 minutes .... 37°C resulted in significant DNA damage .... preincubation with the flavonoids before H2O2 exposure significantly .... protected .... cells against H2O2-induced DNA damage"

So does this.

IMO, most women know that hair cannot be repaired when damaged, but it can be helped to look and feel better.

Re: Possible way to protect hair from conventional peroxide damage
I removed spices from the potential recipe to now just include chamomile tea and oil. Spices can be a pain literally, as they can be sensitizers.
I recommend patch testing chamomile tea, just in case, for allergies.
Either of the 2 oils, coconut or EVOO both contain constituents shown to be protective against H202 damage.
The constituent in coconut oil, gallic acid, is also a chelator.
Now it is a question of what strength the tea needs to be as a pretreatment, which is the only option for it to be used against conventional hydrogen peroxide IMO, unless there is any conventional peroxide on the market with chelators in it.
I do not know what P&G created after applying for the patent.
Re: Possible way to protect hair from conventional peroxide damage
If I were going to colour my hair with a product that contained conventional peroxide, I would make chamomile tea, add an oil and pretreat my hair.
Chamomile tea is inexpensive and easy to find. The recipe is harmless, may be conditioning and may protect against conventional H202 damage.

How much colour would it add to the hair? Not that much from my experience, having used as much as 8-10 tea bags at a time and even so, the colour is temporary.
Used only once a month or every 6 weeks, it should not build-up either, IMO. I had build-up problems with it, using it every time I washed my hair, twice a week. I also had problems with German chamomile being drying but the addition of the oil should prevent that, IMO.

Re: Possible way to protect hair from conventional peroxide damage
Most herb teas will add a bit of colour to the hair, IMO, depending on the strength of the tea used.
I looked into Smooth Move tea, which from a report, added ash tones to hair, but I stopped when I found that licorice root one, of its ingredients, is high in iron. The safety record for licorice did not impress me either. While I do not think occasional use of the tea is harmful, for this purpose and different strengths of a tea experimented with, I think that it is better to pass on this one.
In any case, orange peel contains Vitamin C

Not to my knowlege.
Re: Possible way to protect hair from conventional peroxide damage
Welp - my husband just brought home a bottle of hydrogen peroxide. I have a large stash of chamomile tea and coconut oil.
What I'll probably do is soak the hair in the chamomile/oil treatment, and then pick a few streaks to test the peroxide on. I'm going to try to keep it off all my natural hair growth, and just go where the henna line starts. Assuming I work up the nerve. A few small streak samples shouldn't be too dangerous though.
