Possible way to protect hair from conventional peroxide damage

[ktani]

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.
