Shampoos are viscous formulations used to cleanse hair, remove oil and dirt build-up and product build-up from scalp to ends. Shampoos typically include detergents like sodium lauryl sulfate or sodium laureth sulfate along with cosurfactants like cocamidopropyl betaine for an efficient cleanse and adjust pH level while preservatives extend shelf-life and fragrance add an aromatic element to their formulations.
Some shampoos are designed specifically for particular hair types and conditions, such as those designed to address dandruff. Others support hair growth or thickness.
They clean your hair & scalp
Shampoos are used to clean away daily soil build-up from hair fibres and the scalp, such as sebum (natural oil) and styling products such as sprays or gels used to style hair. Furthermore, shampoos help clear away seborrheic dermatitis on the scalp by cleaning away debris that accumulates over time.
Shampoo’s primary cleaning agents are surfactants, which bind with hair fibres and dissolve them. Modern shampoos contain different combinations of surfactants tailored specifically for various hair and scalp types; additionally they contain preservatives to maintain germ-free conditions as well as fragrances or colours to give an after-the-salon experience.
Medicated shampoos are designed to offer additional benefits beyond cleansing the hair and scalp, such as relieving itching. Common ingredients in medicated shampoos include tar derivatives, corticosteroids, salicylic acid, sulfur, selenium sulfide, polyvinylpyrrolidone-iodine complex, chlorinated phenols or zinc pyrithione; they’re often used to treat conditions like psoriasis, dandruff and others; other functions may include keratolytic, antiseptic or astringent properties depending on their use based on type or condition such as antiseptic or astringent properties;
They are made for dry hair & oily hair
If your scalp produces more sebum and you experience greasy hair, a shampoo specifically formulated for oily hair could be beneficial. They’re lighter in consistency to remove excess oil without stripping the natural moisture out of your locks; plus they may help control dandruff or balance out scalp conditions by using ingredients such as tar derivatives, corticosteroids, salicylic acid or selenium sulfide which contain treatments such as these to address conditions like psoriasis.
Shampoos typically include a mixture of surfactants (surface active agents or detergents), co-surfactants such as cocamidopropyl betaine, pH regulators like citric acid and sodium hydroxide, pH adjustors like polyvinylpyrrolidone-iodine complex or ethylenediaminetetraacetic acid as chelating agents; sequestrants like calcium carbonate; fragrance or other cosmetic or medicinal ingredients plus water as ingredients – The INCI list provides an insight into what makes up your shampoo.
They are sulphate free
If your scalp is sensitive, or if you use leave-in conditioners or styling products frequently, sulfate-free shampoo may be the right solution for you. These formulas do not produce excess suds — which could potentially strip away hair color or natural protective oils — potentially leaving behind lasting damage in your locks.
Sulfates such as sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES) are detergents used to produce foam. Shampoos that use these sulfates include sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES), used widely in many shampoos and shower gels to remove grime, dirt, oil from hair and skin; they’re often harsh on scalps and can dry out hair, leaving itchy or flaky feels. Sulfate-free shampoos do an equally effective job while being gentler on eyes if any drops end up getting into them; plus they’re better for the environment!
They are good for your hair
Shampoos contain various ingredients designed to cleanse and condition your locks, such as surfactants that dissolve oil and dirt on your scalp and preservatives to stop mold growth, while they may even include moisturizers like shea butter or glycerin to soften and nourish strands.
If you have colored hair, finding a shampoo that won’t strip it of its hue is of paramount importance. These gentle surfactants won’t strip your strands as effectively than conventional shampoos do.
If you have fine or thin hair, a volumizing shampoo can add body to it. These lighter formulas typically include keratin protein to open hair cuticles for better growth; silicones lubricate hair and reduce friction to protect it; while their uncharged fatty alcohols make detangling simpler as less likely interactions between negatively charged surfactants exist in their composition.
