The shampoo is a hair care product, typically in the form of a viscous liquid that is used for cleaning hair. The typical reason for using shampoo is to remove the unwanted build-up of sebum in the hair without stripping out so much as to make hair unmanageable.
TYPES OF SHAMPOO:
- Clarifying shampoo: the clarifying shampoo also referred to as the deep cleaning shampoo contains heavy-duty surfactants. This is to remove any build-ups caused by using too many substantive products over a long time; heavy conditioners, hair sprays, silicone products, gels, etc. This is an occasional shampoo and most of them use the sulfate surfactants for that purpose. Consistent usage can strip the hair of its oils as such cause problems.
- Everyday shampoo: The everyday shampoo is the opposite of clarifying shampoo. Many people face the need to shampoo every day, either because their tolerance for sebum is low or by force of habit. Showering without shampoo doesn’t feel hygienic. For those people, a mild shampoo is required. The everyday shampoo doesn’t strip and cleans just enough. These are often equivalent to baby shampoos which also contain mild surfactants.
- Volumizing shampoo: As the name suggests, the shampoo is designed to add body and volume to hair. These shampoos usually do not deposit much conditioning quats, oils, or silicones on the hair. Instead, they clean the hair fairly well and often contain ‘special’ ingredients that can deposit on hair to add friction at the roots and build volume
- Oily hair shampoo: the oily hair shampoo is almost similar to the clarifying shampoo. These shampoos are designed to optimize sebum removal from the scalp and hair shaft. This is accomplished by the selection of strong detergents and the minimal use of conditioners. Unlike the clarifying shampoo, the oily hair shampoo doesn’t strip the hair completely. It often contains sulfates or sulfosuccinates detergents.
- Normal hair shampoo: It is for those who don’t need ‘special’ treatments for their hair. These shampoos will clean well and leave behind a slight layer of conditioning as well. They usually contain sulfates balanced with other surfactants. They are formulated to clean just enough for normal sebum production.
- Dry damaged hair shampoo: Dry and damaged hairs are usually lumped together because both require heavy conditioning. These shampoos are mild. Their goal is to cleanse gently and deposit protective layers to the hair. The detergents remove the environmental dirt and sebum from the hair in the water-soluble phase, but the oils, silicones and other conditioning agents stay behind as a thin coating over the hair shaft.
- Coloured hair shampoo: In terms of surfactants, these almost exclusively sulfate-free nowadays. They are mild and tend to add conditioning like the ones for dry damaged hair. Some of these shampoos will have colour boosters added to help revitalize the shades. Many have UV protecting ingredients and antioxidants to protect the colour.
- 2-in-1 shampoo: It offers both cleansing and conditioning in one bottle. They are slightly more conditioning than the other mild shampoos to the point that a conditioner is not needed. These are practical and work fine for hair that needs a gentle cleaning and a decent amount of conditioning. However, there are limitations to its usage and not everybody will benefit from this type of shampoo.
- Medicated shampoo: They are designed to deliver some other benefit to the scalp besides cleaning. The most common medicated shampoos are aimed at relieving scalp itch and / or scaling. 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. Medicated shampoos have several functions; to remove sebum efficiently, to remove scalp scale, to decrease scalp scale production, and to act as an antibacterial/ antifungal.
Of the medicated shampoo categories, are also those designed for thinning hair. Some will contain minoxidil to prevent further hair loss. Others will contain natural essential oils that help stimulate blood flow in the scalp. They are often designed to create more volume and give more body to thin hair.
- Swimmer’s shampoo: These shampoos are specifically formulated to remove pool chlorine and copper from the hair, they contain a chelating agent which can trap the copper ions, and often contain ascorbic acid which will break the chlorine interactions with the hair.
