question: What is the difference between shampoo, shower gel and normal hand soap?
comment: In the end they all are effectively just soap. A brick of soap is the pure stuff and by wiping your wet hands over it you remove just enough to wash your hands. Shower gel and shampoo are diluted with water, which just makes them easier to apply. You can massage them in your hair, which would be much more difficult with a brick of soap. Also further chemicals are added to adjust the viscosity (how liquid it is), color, smell etc. some shampoos might also contain actual active ingredients like selenium for anti dandruff shampoo. But most of it is just marketing, don't fall for it.
passages: Shower gels for men may contain the ingredient menthol, which gives a cooling and stimulating sensation on the skin, and some men's shower gels are also designed specifically for use on hair and body. Shower gels contain milder surfactant bases than shampoos, and some also contain gentle conditioning agents in the formula. This means that shower gels can also double as an effective and perfectly acceptable substitute to shampoo, even if they are not labelled as a hair and body wash. Washing hair with shower gel should give approximately the same result as using a moisturising shampoo.
  
  Section::::Marketing.
   Like shampoo and bubble bath products, many are marketed directly towards children. These often feature scents intended to appeal to children, such as fruit scents, or cookies or cotton candy scents. Many bottles feature popular characters from children's television or movies. As with men's body wash, they often are specifically designed to be used also as a shampoo and conditioner. They also often contain gentle ingredients designed for young skin.
   Pet shampoos which include fragrances, deodorants or colors may harm the skin of the pet by causing inflammations or irritation. Shampoos that do not contain any unnatural additives are known as hypoallergenic shampoos and are increasing in popularity.
  
  Section::::Specialized shampoos.:Solid.
  
  Solid shampoos or shampoo bars use as their surfactants soaps or other surfactants formulated as solids. They have the advantage of being spill-proof. They are easy to apply; one may simply rub the bar over wet hair, and work the soaped hair into a low lather.

   Shower gels are known to consist of the same basic ingredients as soap - water, betaines, and sodium laureth sulfate, or SLS. But the main difference between the two products lie in its surfactants - compounds known to lower the surface tension between substances, which helps in the emulsification and the washing away of oily dirt. The surfactants of shower gels do not come from saponification, that is by reacting a type of oil or fat with lye. Instead, it uses synthetic detergents for surfactants derived from either plant-based sources or petroleum. This gives the product a lower pH value than soap and might also feel less drying to the skin. Some people have likened the effect to feeling less "squeaky clean", however. 
   Shampoo is generally made by combining a surfactant, most often sodium lauryl sulfate or sodium laureth sulfate, with a co-surfactant, most often cocamidopropyl betaine in water to form a thick, viscous liquid. Other essential ingredients include salt (sodium chloride), which is used to adjust the viscosity, a preservative and fragrance.

   Most contain sodium trideceth sulfate, which is formulated to act as a low-irritation cleansing agent.
  
  Alternatively, baby shampoo may be formulated using other classes of surfactants, most notably non-ionics which are much milder than any charged anionics used.

  Section::::Types of Dry Shampoos.:Herbal Powder Shampoo.
  
  Herbal powder shampoos are another form of dry shampoo. As a natural hair-care product, they tend to have fewer negative side effects than traditional mass-market shampoos, and contain a dry powder mixture of aloe vera and other plant byproducts to reduce skin, eye, and scalp irritation from surfactants.

   Proactiv is a registered trademark of Guthy-Renker. The brand's primary product is a three-step kit comprising a cleanser, toner and lotion, which sells for $20 a month in the United States if purchased as part of the continuity program.
   Shower gel is a derivative invention of the liquid soap, which first appeared in the 1800s. In 1865, William Shepphard patented the formula behind the liquid soap, but the product gained eventual popularity with the rise of Palmolive soap in 1898, by B.J. Johnson.
  
  Modern chemistry later enabled the creation of the shower gel, which specialized in cleaning the entire body during baths and showers.

   Originally, soap and shampoo were very similar products; both containing the same naturally derived surfactants, a type of detergent. Modern shampoo as it is known today was first introduced in the 1930s with "Drene", the first shampoo using synthetic surfactants instead of soap.
  
  Section::::History.:Indonesia.
   The considerations in 3 and 4 frequently result in a much greater multiplicity of surfactants being used in individual baby shampoos than in other shampoos, and the detergency or foaming of such products may be compromised thereby. The monoanionic sulfonated surfactants and viscosity-increasing or foam stabilizing alkanolamides seen so frequently in other shampoos are much less common in the better baby shampoos.

   Shower gel
  
  Shower gel (also shower cream or body wash) is a specialized liquid product used for cleaning the body during showers. Not to be confused with liquid soaps, shower gels, in fact, do not contain saponified oil. Instead, it uses synthetic detergents derived from either petroleum or plant sources.
  
  Body washes and shower gels holds a lower pH value than the traditional soap, which is also known to feel less drying to the skin. In certain cases, sodium stearate is added to the chemical combination to create a solid version of the shower gel.
  
  Section::::History.
   BULLET::::- adjusting pH to that of "non-stress tears", approximately 7, which may be a higher pH than that of shampoos which are pH adjusted for skin or hair effects, and lower than that of shampoo made of soap
  
  BULLET::::- use of surfactants which, alone or in combination, are less irritating than those used in other shampoos
  
  BULLET::::- use of nonionic surfactants of the form of polyethoxylated synthetic glycolipids and/or polyethoxylated synthetic monoglycerides, which counteract the eye sting of other surfactants without producing the anesthetizing effect of alkyl polyethoxylates or alkylphenol polyethoxylates
   Surfactants can make up as much as 50 percent of the shower gel content, with the remaining proportion being made up of a combination of water and ingredients to thicken, preserve, emulsify, add fragrance, and color. Multiple surfactants are often used to achieve desired product qualities. A primary surfactant can provide good foaming ability and cleaning effectiveness, while a secondary surfactant can add qualities of mildness to prevent irritation or over-drying of the skin. To prevent shower gel ingredients from separating, emulsifiers such as diethanolamine are added. Conditioning agents may also be added to moisturize the skin during and after product use. They are also available in different colours and scents. Ingredients, like scent in the form of essential oils or fragrance oils and colorant in the form of water soluble dyes are common in shower gels. 
   The distinction in 4 above does not completely surmount the controversy over the use of shampoo ingredients to mitigate eye sting produced by other ingredients, or the use of the products so formulated.

   Shampoos that are especially designed to be used on pets, commonly dogs and cats, are normally intended to do more than just clean the pet's coat or skin. Most of these shampoos contain ingredients which act differently and are meant to treat a skin condition or an allergy or to fight against fleas.
   The typical reason of using shampoo is to remove the unwanted build-up of sebum in the hair without stripping out so much as to make hair unmanageable. Shampoo is generally made by combining a surfactant, most often sodium lauryl sulfate or sodium laureth sulfate, with a co-surfactant, most often cocamidopropyl betaine in water.
   Sodium laureth sulfate, or sodium lauryl ether sulfate (SLES), is a detergent and surfactant found in many personal care products (soaps, shampoos, toothpastes, etc.). It is an inexpensive and effective foamer. Sodium lauryl sulfate (also known as sodium dodecyl sulfate or SDS) and ammonium lauryl sulfate (ALS) are commonly used alternatives to SLES in consumer products.

  Hair gel is a hairstyle product that is used to stiffen hair into a particular hairstyle. The end result is similar to, but stronger than, those of hair spray. Hair gel is most commonly used in the hairstyling of men, but it is not gender specific. Hair gel can come in tubes, pots, small bags, or even in a spray form.
