Let's start with the most common problem: excessive hair grease. If your hair is dry by nature, retain moisture, "hard" shampoo or a perm, it is necessary to restore normal fat content. Shampoos with a reduced washing action and overfatting additives will help. Shampoo for dry hair can also include substances that stimulate the sebaceous glands, such as extract of red hot pepper.
There are shampoos (for example, "Johnson's pH 5.5), the use of which especially helps to strengthen hair. With regard to a stable pH, coinciding with an isoelectric point of the main structural protein of hair keratin - it's not a gimmick, but the truth. (However, most foreign shampoos are quite stable pH) Constant pH buffer support special additives. Such a shampoo, in contrast to the soap solution with a high, alkaline pH, did not violate the spatial structure of keratin.
For brittle, split ends, hair weakened by "chemistry", is now also easy to find a suitable shampoo. It is usually enriched with amino acids, vitamins, and may include oil, lecithin, vegetable extracts, protein condensates and esters of natural fatty acids, silicones. Good nutritious oils are olive, grape stone fruits, jojoba oil, cocoa, castor, Masaya. Even with frequent use of these shampoos hair is flexible and mild. A similar effect is achieved with application of balms, conditioners for dry and damaged hair.
In the so-called "soft" shampoos conventional surfactants like sodium lauryl sulfate partially replaced by a special surfactants, non-irritating: sulfosuccinates, sarcosinates, betaine, glycine, silicones. Unsurpassed in softness to the skin and mucous membranes of the eyes are shampoos without tears, "the firm Johnson & Johnson (USA).
Antidandruff shampoos are very popular too. Driving attention: "Fa Dandruff", "Head & Shoulders", "Palmolive Antidandruff", "Seborin", "Raffil", "Nivea" and "Wella gegen Schuppen". Dandruff - it is, in fact, the drying and flaking of young skin cells. Peeling is accompanied by active cell division and growth, which, in turn, also hulled. To avoid this, you need to slow down not only the dry cells, but the processes of divide. To do this, are substances with cytotoxic and bactericidal action - for example, piritionat zinc, and selenium disulfide octopirox. They are insoluble in the shampoo are entered in the form of fine dispersions - that's why these shampoos are opaque.
