Shampoo cleans by stripping sebum from the hair. Sebum is an oil secreted by hair follicles that is readily absorbed by the strands of hair, and forms a protective layer. Sebum protects the protein structure of hair from damage, but this protection comes at a cost. It tends to collect dirt, styling products and scalp flakes. Surfactants strip the sebum from the hair shafts and thereby remove the dirt attached to it. While both soaps and shampoos contain surfactants, soap bonds to oils with such affinity that it removes too much if used on hair. Shampoo uses a different class of surfactants balanced to avoid removing too much oil from the hair. The chemical mechanisms that underlie hair cleansing are similar to that of traditional soap. Undamaged hair has a hydrophobic surface to which skin lipids such as sebum stick, but water is initially repelled. The lipids do not come off easily when the hair is rinsed with plain water. Shampoo applied to wet hair is absorbed into the oil/hair interfaces. The anionic surfactants substantially reduce the interfacial surface tension and allow for the removal of the sebum from the hair shaft. The non-polar oily materials on the hair shaft are solubilised into the surfactant micelle structures of the shampoo and are removed during rinsing. There is also considerable removal through a surfactant and oil ';roll up'; effect.Is shampoo scientifically proven to help your scalp?
IT only makes your hair smell pretty,,,,lol....... umm probably stops dandruff, not to mention other small CLEAN bugs,, HAHAHA
What exactly is your question?





Medicated shampoos clearly help your scalp. They use the same ingredients that dermatologists prescribe for things like eczema. I cannot get through a winter without Head and Shoulders and Selsun Blue. Other shampoos work differently depending on your skin/hair conditions and the water you are washing with. Your scalp is simply part of your skin, but the problem is that you have to have something that both cleans your hair and moisturizes your skin. Not easy. Water conditions make it even less easy.





For instance, I lived in 2 different apartments (one with well, one with city water from river), a trailer park (nasty well water) and a home (city water from well). My hair tends to be oily. I had to change shampoos at every location because it either left a scummy feeling to my hair or dried out my scalp resulting in itchy, itchy, itchy. Some shampoos include moisturizers that clearly help your scalp--unfortunately, most of those shampoos work for normal hair and not oily.





If you do not have hair or have buzz cut, then I think you could go with Irish Spring and not buy other shampoo. Using soap in your hair will make it icky over time, but if it works for you, go for it.
dude, that's nasty. it keeps yer hair from getting greasy and crap.
