Hair conditioner is a hair care product used to enhance the taste, appearance and management of hair. The main purpose is to reduce friction between the hair strands to make it easier to brush or comb, which may cause damage. Various other benefits are often advertised, such as hair repair, reinforcement, or split-end reduction.
The conditioner is available in various forms including viscous liquids, gels and creams and lotions and thinner sprays. Hair conditioner is usually used after hair washed with shampoo. It is applied and worked into the hair and can be washed moments later or left in.

History
For centuries, natural oils have been used to condition human hair. The popular conditioner with men in the late Victorian era is Macassar oil, but the product is quite oily and requires a small cloth clamp, known as antimacassar, to the chair and sofa to keep the coatings from being damaged by oil.
The modern hair conditioner was created at the turn of the 20th century when the perfumer ÃÆ' â € ° douard Pinaud presented a product he called Brilliantine at the 1900 Universelle Exhibition in Paris. Its products are meant to soften men's hair, including beard and mustache. Since the discovery of Pinaud's early products, modern science has developed a hair conditioning industry for inserts made with silicon, fatty alcohol, and quaternary ammonium compounds. These chemical products have the benefit of a hair conditioner without feeling oily or heavy.
Hair conditioner is different from creme rinse (sometimes spelled "cream rinse"). Rinse creme is just a "detangler" that has a thinner consistency than conditioner, as the name implies. Hair conditioner is a thicker liquid that covers the hair cuticle itself.

Action mechanism
The outermost layer of the hair follicle is called the cuticle and is largely composed of keratin. It is rich in a slightly acidic cysteine ​​group. When the hair is washed these groups can be deprotonate, giving the hair a negative charge. Positive quaternary ammonium species, such as behentrimonium or polyquaternium, can then attach to the hair through electrostatic interactions.
Once embedded, this compound has several effects. The long hydrocarbon backbone helps lubricate the surface of each hair follicle, reducing the sensation of roughness and helping to comb. The cationic group surface coating means that the hair is repelled from one another electrostatically, which reduces clumping. The compound may also act as an antistatic agent, which helps reduce curling.
The conditioner type
- Package heavy and thick conditioners, with high surfactant content that can bind the hair structure and "glued" the hair surface together. This is usually applied to the hair for a longer time. Surfactants are based on a long straight chain of aliphatic fatty acids similar to saturated fatty acids. Their molecules have a tendency to crystallize easily, provide a higher viscosity conditioner, and they tend to form thicker layers on the surface of the hair. The
- Leave-in conditioner is thinner and has a different surfactant, which adds only a small amount of material to the hair. They are based on a chain of unsaturated fatty acids, which are bent, not straight. These shapes make them less susceptible to crystallization, making the mixture lighter, less viscous and giving thinner layers to the hair. The difference between the pack and the leave-in conditioner is similar to the difference between fat and oil, the latter less viscous. The non-rinse conditioner is designed to be used in a manner similar to hair oil, preventing the hair from tangling and keeping it smooth. Its use is very prevalent for those who have curly or natural curly hair. The
- Ordinary conditioner combines several aspects of pack and leave-in conditioner. Normal conditioners are generally applied directly after using shampoo, and manufacturers usually produce conditioner partners for different types of shampoo for this purpose. Condenser
- Hold , based on cationic polyelectrolyte polymer, hold the hair in the desired shape. It has a function and composition similar to diluted hair gel.
Materials
There are several types of hair conditioner, different in composition and function:
- Moisturizer, which plays moisture in the hair. Usually this contains humectant with high proportions. It can also be supplied by natural oils such as almond oil
- Reconstruction, usually containing hydrolyzed protein. Their role should penetrate the hair and strengthen its structure through the crosslinking of the polymer.
- An oxidizing agent, an acid regulator that maintains a pH of about 3.5. In contact with the acidic environment, the surface is slightly scaly hair tightening, because the hydrogen bond between the keratin molecules is amplified.
- Detanglers, which modify the hair surface by pH as an acidifier, or coat it with a polymer, as a glosser.
- Thermal protectors, usually heat-absorbing polymers, protect hair from excessive heat, caused by, for example, draining by blowing, curling or hot rollers.
- Glosser, a light reflecting chemical that binds to the surface of the hair. Usually polymers, usually silicon, for example, dimethicone or cyclomethicone.
- Oil (EFA - essential fatty acids), which can help dry hair/porous become softer and more flexible. The scalp produces a natural oil called sebum. EFA is the closest thing to natural sebum (sebum contains EFA).
- Surfactants - about 97% of the hair consists of a protein called keratin. The surface of keratin contains negatively charged amino acids. Therefore, hair conditioners usually contain cationic surfactants, which do not wash completely, because the hydrophilic end is heavily bound to keratin. The hydrophobic tip of the surfactant molecule then acts as the surface of the new hair.
- Lubricants, such as fatty alcohols, panthenol, dimethicone, etc.
- Sequestrants, for better functioning in hard water.
- Antistatic Agents
- Preservatives
- Sunscreen, for protection against protein degradation and loss of color. Currently benzophenone-4 and ethylhexyl methoxycinnamate are the two most commonly used sunscreens in hair products. Cinnamidopyltrimonium chloride and several others are used at much lower rates. Sunscreen commonly used on the skin is rarely used for hair products because of its texture and heavy effects.
pH
The conditioner is often acidic, because low pH protects the keratin amino acids. The hydrogen ion gives a positive charge on the hair and creates more hydrogen bonds between the keratin scales, giving the structure a more compact hair. Organic acids such as citric acid are usually used to maintain acidity.
