The use of conditioners on oily hair is not necessary due to ample sebum production. A newcomer to the shampoo market is the everyday shampoo. Many persons feel that they do not have good hygiene unless they bathe daily. Technically, it is not necessary to shampoo the hair daily unless sebum production is high. Shampooing is actually more damaging to the hair shaft than beneficial.
Everyday shampoos have been designed to meet the needs of the daily bather and generally contain mild detergents. They typically do not incorporate the conditioners found in the dry or damaged hair shampoos, and an instant conditioner can be used in combination with these products. Instant conditioners are applied immediately after shampooing in the shower and completely rinsed from the hair prior to drying.
Deep cleaning shampoos, also known as clarifying shampoos, are at the other end of the spectrum from everyday shampoos. They are designed to thoroughly remove sebum from the hair shaft, but are typically used to remove retained styling products, such as hair spray, gel, and mousse. Everyday shampoos and dry hair shampoos are not good at removing the polymer film created by hair care products designed to keep the hair in place. These polymers can build up on the hair shaft after seven days use and leave the hair feeling harsh and appearing dull.
In order to remove the polymer, a strong detergent in the form of a deep cleaning shampoo is used. These shampoos are typically used once weekly to keep the hair free of hair styling product build up. These shampoos, like the oily hair shampoos, use lauryl sulfates as their primary detergent. Baby shampoos are non-irritating to the eyes and designed as mild cleansing agents, as babies produce limited sebum.
These shampoos use detergents from the amphoteric group, such as the betaines. Thus, eye damage can still occur if the baby shampoo is accidentally introduced into the eye, but the injury is not painful unless the anesthetic effect of the shampoo is no longer present.
Medicated shampoos are designed to deliver some other benefit to the scalp besides cleansing. These products are classified as over-the-counter drugs, as they contain active agents such as, tar derivatives, salicylic acid, sulfur, selenium sulfide, polyvinylpyrrolidone-iodine complex, chlorinated phenols or zinc pyrithione. The shampoo detergent removes the sebum, while mechanical scrubbing removes the scalp scale.
Tar derivatives are commonly used as anti-inflammatory agents. Salicylic acid is added as a keratolytic and menthol is added to some shampoos to produce a tingling sensation that some patients find esthetically pleasing, and to provide a secondary stimulus, which neurologically decreases the perception of scalp itching. Professional shampoos are sold through beauty supply houses and are designed for special salon use. There are two types of professional shampoos: those intended for hair washing prior to cutting or styling and those intended to precede or follow a chemical process.
Professional shampoos for hair washing are the same formulation as the over-the-counter varieties except that they are more concentrated and must be diluted eight to ten times before use. Otherwise, they contain the same formulation and variety of specialty additives discussed earlier.
There is a perception among beauticians that salon shampoos are superior to mass market shampoos because they offer hair benefits not otherwise obtainable. It is hard to evaluate this opinion, as hair salons derive a significant profit from product sales. However, it can be stated that there are no ingredients present in salon shampoos that have not been incorporated into those sold in the general market. A special subset of professional shampoos that are not sold to the general public or are sold only in conjunction with home hair dyeing products are the anionic, acidic professional shampoos used after bleaching to neutralize residual alkalinity and prepare the hair for subsequent dyeing.
These shampoos perform a vital function in preventing irreversible hair damage during the bleaching procedure. When the hair is exposed to an alkaline pH, as discussed previously, the cuticular scale swells and makes the hair shaft more porous. The use of an acidic shampoo restores the normal cuticle configuration and prevents excessive dye damage to the hair shaft.
Another category of special professional shampoos are those designed for use after completion of the dyeing procedure. These are cationic, acidic shampoos used after dyeing to act as a neutralizing rinse. These products also decrease cuticular swelling to prevent the new color moieties from exiting the hair shaft, resulting in color fading.
These special shampoos designed for use with hair coloring procedures are generally only available to licensed cosmetologists, as they are not appropriate for daily cleansing. Adverse reactions to shampoos are rare, as the product is rinsed away from the skin quickly allowing insufficient time for the development of allergic or irritant contact dermatitis. Probably the most common problem with shampoo is accidental contact with the mucous membranes, such as the nose and eye.
The possible causes of allergic contact dermatitis are listed in Table 4. However, it should be recognized that false positive reactions due to irritation may still occur. A better assessment may be obtained by patch testing individual ingredients separately.
Shampoos are a complex formulation of ingredients selected to clean the scalp, as well as beautify the hair. This is a complex task leading to the wide variety of shampoos currently in the market. Selecting the proper shampoo for a patient with a given dermatologic hair disorder means understanding the various ingredient functions and the unique attributes of each shampoo type. This article has presented some fundamental knowledge in this regard. Source of Support: Nil. Conflict of Interest: None declared.

Open in a separate window. Table 2 The most common shampoo detergents. You can try DKoye's The Conditioner, which helps replenish the lost moisture from shampooing.
It is specifically designed for chemically treating hair, so your colored locks will benefit so much from using this product. It also smells good and with continued use, it will help bring back your hair's original strength and luster.
While choosing a good conditioner is important, it's still best to choose a good shampoo that will nourish and clean your hair at the same time. DKoye's The Shampoo contains seaweed, algae and kelp extracts that can help retain your hair's moisture and demineralize your locks. The result? Other surfactants that are primarily used for lathering include Cocamidopropyl MEA and Cocamidopropyl betaine.
Pearling Agents : These are used mainly to create a beautiful appearance of the product for aesthetic appeal. Without these ingredients in shampoo and most cosmetic products the appearance of the shampoo or product may not be appealing. This is why pearling agents are utilized to give shampoo and most cosmetic products a nice appealing presentation.
Pearling agents are most times inert and do not interfere with the active ingredients in shampoos surfactants. Examples of pearling agents include Glycol Distearate.
Conditioning Agents: Typically, after the shampoo has cleansed the hair of dirt and oil sebum , the hair shaft becomes dry clean and dry because of the cleansing process. This can cause the cuticle on the hair shaft to become brittle and rough which causes the hair to break easily.
To prevent the cuticle on the hair shaft from becoming dry and brittle, ingredients that are conditioning agents are included in shampoo formulations. These components normally coat the hair shaft to make it smooth and prevent it from getting dry and brittle. This is another good importance of shampoo. Examples of conditioning agents in shampoo include Dimethicone, Guar Hydroxypropyltrimonium Chloride.
PH Adjuster: PH adjusters are generally used in keeping the ph level of any medium stable. Shampoos have PH adjusters too because of the chemical ingredients that are used. PH adjusters keep shampoo ph very stable and safe for your hair. Preservatives : This shampoo ingredient does not really play an active role in cleansing your hair but it is important all the same. Preservatives prevent microorganisms from growing in the shampoo medium keeping it clean and germ-free.
Fragrance: The role of fragrances is quite obvious. It masks out the unpleasant odors that some of the ingredients can have with pleasant good odors. Shampoos are typically available in various nice smelling fragrances. Can jeans be altered and why would you want to alter a jeans outfit? Denim jeans are undeniably a staple in the closets of people all over the world.
If you wash with conditioner only, be sure to avoid any hair products with silicone, as they may leave your hair feeling weighed down, dull, and lifeless. Avoid products containing ingredients like cyclomethicone, dimethicone, and amodimethicone, as these are some of the most commonly used silicones. If you do use conditioners with these ingredients, you may need to use a clarifying shampoo every 2 weeks to clear buildup.
If you have very coarse or curly hair, you can also try a condition-shampoo-condition regimen, as coarse hair tends to lose moisture very quickly. Traditionally, shampoos are used before conditioners to ensure that enough dirt and oil are removed from the hair. While there are no scientific studies to support reverse hair washing, some stylists recommend it for people with very dry or fine hair who still want the hydrating benefits of conditioners without the added weight and excess moisture.
The dirtier your hair gets and the more oil you produce, the more often you have to wash your hair with shampoo first. On days you use a mild or clarifying shampoo, follow with a conditioner. How often you wash your hair will depend on your type of hair, styling preference, and lifestyle. Despite what shampoo commercials lead you to believe, washing your hair can be a key contributor to a bad hair day. Though it may seem like a purely cosmetic treatment, daily conditioner is recommended for all people to help maintain healthy and strong hair.
