Why Dimethicone Hurts Hair
The word shampoo, derivative from words meaning "massaging," did not appear in the English language as a "soap formulated for clean the hair," until the mid- 1800s. Since then, scientists have developed products that can improve hair superiority in as slight as 30 seconds, or the amount of time most shampoos stay on hair. Shampoos consist primarily of three agents - surfactants, and cationic polymers - along with preservatives, perfumes, and, sometimes, dyes and anti-dandruff ingredients. Surfactants contain together hydrophobic ingredients, those attracted to oil, and hydrophilic ingredients, those involved to water, allowing shampoo to bind to and emulsify dirt, sebum and styling goods in the hair and then remove them when rinsing. Silicones are reliable for lubricating the hair, allowing for easier brushing and a smoother like and feel to the hair when dried. Cationic polymers provide single wet-conditioning and delivery benefits, allowing various consumers to forgo a separate conditioner if their hair is already in excellent condition.
Conditioners contain several of the same ingredients found in shampoos but in concentrations and amounts to provide unusual benefits. In conditioners, cationic polymers are attracted to injured areas on the hair's cuticle surface and fortify weak areas while adding structure and body to the hair. Higher levels of conditioning are found in conditioners designed to silky, reduce frizz or provide higher moisture.
A further form of conditioner is the leave-in treatment, which is designed to stay in the hair and be focused in areas (i.e. ends) that require additional hydration and protection. Some styling products such as ointment, lotions/milks and pomades not just provide style achievement reimbursement with their polymer holding ingredients, but also offer moisture and shine enhancement during the addition of conditioning ingredients such as dimethicone.
The similar hair, treated and untreated, highlights the benefits that conditioning agents can offer. Trends in current years have moved towards a wide range of shampoos and conditioners specifically targeted for particular types of hair, from color-treated to dry, fine or curly.
