Hair Bleaching Damage Prevention

Preparing a low-damage rapid hair bleaching agent that effectively bleaches hair while significantly reducing damage to hair and scalp. The bleaching agent formula aims to reduce irritation of chemical substances and hair structure damage while maintaining bleaching effectiveness. The method involves combining specific ingredients in a specific order to prepare the bleaching agent. The steps are: 1. Preparing a first mixture by dissolving sodium lactate, sodium chloride, and sodium citrate in water. 2. Preparing a second mixture by dissolving hydrogen peroxide and ammonium persulfate in water. 3. Combining the first and second mixtures to obtain the final low-damage rapid hair bleaching agent.

Method of treating curly hair during bleaching to maintain curl definition, prevent curl elongation, improve hair integrity, and provide frizz control. The method involves applying a specific hair treatment composition before, during, or after the bleach. The treatment contains carboxylic acids, cyclodextrins, polysaccharides, polyols, and water with a pH less than 7. The treatment helps maintain curl shape, prevent curl elongation, improve curl definition, and restore hair integrity during bleaching compared to bleaching alone.

Protecting hair from damage during bleaching by pre-treating it with a keratin-based film-forming agent. The pre-treatment involves applying an aqueous mixture containing hydrolyzed keratin and a silane crosslinking agent to the hair. When dried, this forms a protective film on the hair surface. The film sacrifices during bleaching to minimize damage compared to untreated hair. The hydrolyzed keratin and silane react to crosslink and form a protective barrier that prevents bleach chemicals from penetrating deep into the hair shaft.

Method for dyeing or bleaching hair that enhances color intensity, reduces hair damage, and repairs damaged hair. The method involves applying two separate compositions to the hair in succession. The first composition contains a hair colorant or bleaching agent, and the second composition contains a hair treatment with amide and/or alkylammonium carboxylate compounds. This sequence of applications helps to improve color retention, minimize discoloration, and lessen hair damage compared to using just the first composition alone.

Aqueous oxidizing composition for gentle and selective bleaching and oxidative dyeing of keratin fibers like hair. The composition contains hydrogen peroxide at a pH of 1-6, along with thickening polymers. It can be used in two-part systems for bleaching and dyeing hair. The first part contains a polycarboxylic acid like phosphoric acid. This allows controlled release of hydrogen peroxide during bleaching/dyeing. The pH-controlled oxidizing composition reduces damage compared to traditional high pH oxidizing agents. It also enables selective oxidation of hair color components like melanin intermediates.

Bleaching human hair using a new bleaching agent and method to achieve high whiteness, no yellowing, low pollution, and low damage to hair strength compared to traditional bleaching methods. The bleaching agent is made by adding scouring agent and penetrating agent to water, then aluminum-based polyacid compound. The pH of the bleaching agent is 6-12. The method involves using this bleaching agent to bleach hair in a pH range of 6-12. This provides whiter hair without yellowing, lower pollution, and less damage to hair strength compared to traditional high temperature, high alkali hydrogen peroxide bleaching.

A method for dyeing or bleaching hair without damage by controlling the oxidizing agent concentration using hair tonics. The method involves applying a scalp tonic to diagnose hair, then using an oxidizing agent with higher hydrogen peroxide concentration than needed to prepare the oxidizer. This is adjusted to the required concentration using hair tonics for tone-up, tone-down, or normal dyeing. The tonics prevent damage and provide nutrition. In the final step, the adjusted oxidizer and dye/bleach are mixed and applied.

A hair coloring method that uses a specific mix of products and steps to achieve better color retention, reduced skin irritation, and less damage to the hair compared to traditional hair dyes. The method involves decoloring the hair before applying a hair coloring agent and hair cosmetic in a specific ratio. This mixture is left on the hair for a certain time to open the cuticle, then a cuticle care agent is applied to tighten the cuticle and allow deeper dye penetration. The hair is heated during this step. The hair coloring agent contains thioglycerol, basic dyes, hydroxy, and other ingredients to raise the pH without alkaline agents. This allows deeper dye penetration into the cortex. The hair coloring agent pH is 3.5 or higher. The method also allows reducing the amount of basic dyes and HC dyes in the hair coloring agent

Reducing hair damage when using bleaching formulations in hair coloring and treatments. The method involves applying a separate formulation containing an active agent like maleic acid to the hair after bleaching. This formulation repairs and strengthens the hair instead of using hydrogen peroxide to oxidize it. It reduces hair breakage, charge, and damage compared to traditional bleaching alone. The active agent is rinsed off the same day.

Method for bleaching human hair fibers to improve whiteness and reduce damage compared to conventional methods. The process involves complexing and catalyzing the bleaching reaction using specific reagents and conditions. It involves treating the hair fibers with a mixture of hydrogen peroxide, keratin, and a chelating agent like EDTA. The keratin and EDTA help break down the pigment particles in the hair more effectively while protecting the hair structure. The optimized hydrogen peroxide concentration of 25-32% provides better bleaching efficiency. This complexing and catalyzing of the bleaching reaction enhances hair fiber whiteness and reduces damage compared to traditional bleaching methods.

A hair treatment method and agent group that reduces hair damage and improves treatment effectiveness. The method involves using a hair treatment product containing specific keratin molecules with different weight average molecular weights. The keratin with lower molecular weight (300-500) repairs damaged hair, while the higher molecular weight keratin (3000-5000) strengthens hair. This combination along with a pH adjuster is applied during hair treatment. It mitigates damage from agents like dyes, bleaches, curlers, and perm solutions while enhancing their effects.
