This treatment usually lasts from three to four months &#8211; but depending on your aftercare it can last a little longer.&nbsp; In the same way, the lack of specific hair care might remove the protein treatment from your hair sooner than you expected.<\/p>\n\n\n\n<p>And we don\u2019t want that to happen, right? If you want to keep your shiny strands and protein therapy to last longer, there are some tricks that might be really helpful. Among them, one of the most effective is to use a sulfate-free <a href=\"https:\/\/metrobrazil.com\/products\/professional-step-1-shampoo-ph9-and-step-3-hair-mask-kit-by-sao-lindas?_pos=2&amp;_sid=d3d768f98&amp;_ss=r\">shampoo<\/a>.

Although several forms of sulfates are utilized in different industries, the two most commonly used sulfates in the hair care business are sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES).<\/p>\n\n\n\n<p>Petroleum and plant sources such as palm and coconut oil are used to make these chemicals.<\/p>\n\n\n\n<p>Sulfates are thought to be effective cleaning agents. When compared to other cleansing substances, they are claimed to offer the deepest cleansing capabilities. Sulfates are a type of cleaner that belongs to the anionic surfactant family.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"why-to-avoid-sulfate\"><strong>Why to avoid sulfate?<\/strong><\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/metrobrazil.com\/products\/professional-step-1-shampoo-ph9-and-step-3-hair-mask-kit-by-sao-lindas?_pos=2&amp;_sid=d3d768f98&amp;_ss=r\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/blog.metrobrazil.com\/en\/wp-content\/uploads\/sites\/3\/2022\/02\/1-3-1k_2000x-1.jpg\" alt=\"\" class=\"wp-image-3642\" srcset=\"https:\/\/blog.metrobrazil.com\/en\/wp-content\/uploads\/sites\/3\/2022\/02\/1-3-1k_2000x-1.jpg 1024w, https:\/\/blog.metrobrazil.com\/en\/wp-content\/uploads\/sites\/3\/2022\/02\/1-3-1k_2000x-1-300x300.jpg 300w, https:\/\/blog.metrobrazil.com\/en\/wp-content\/uploads\/sites\/3\/2022\/02\/1-3-1k_2000x-1-150x150.jpg 150w, https:\/\/blog.metrobrazil.com\/en\/wp-content\/uploads\/sites\/3\/2022\/02\/1-3-1k_2000x-1-768x768.jpg 768w, https:\/\/blog.metrobrazil.com\/en\/wp-content\/uploads\/sites\/3\/2022\/02\/1-3-1k_2000x-1-600x600.jpg 600w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<p>Sulfates make a very effective cleanse. On the other hand, this type of cleansing is too strong for some hair types and makes them drier. Plus: sulfates not only remove the dirt from our scalp, but also chemical treatments, such as coloration and protein\/keratin treatments.&nbsp;<\/p>\n\n\n\n<p>We got to the right point: sulfate <a href=\"https:\/\/metrobrazil.com\/products\/professional-step-1-shampoo-ph9-and-step-3-hair-mask-kit-by-sao-lindas?_pos=2&amp;_sid=d3d768f98&amp;_ss=r\">shampoos<\/a> remove more keratin than sulfate-free shampoos (that have a milder cleanse). As a result, it lasts much less when you wash your hair with strong sulfates.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"benefits-of-using-it\"><strong>Benefits of using it<\/strong><\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"626\" height=\"417\" src=\"https:\/\/blog.metrobrazil.com\/en\/wp-content\/uploads\/sites\/3\/2022\/01\/lock-hair-shampoo-purple-background_185193-72096.jpg\" alt=\"\" class=\"wp-image-3174\" srcset=\"https:\/\/blog.metrobrazil.com\/en\/wp-content\/uploads\/sites\/3\/2022\/01\/lock-hair-shampoo-purple-background_185193-72096.jpg 626w, https:\/\/blog.metrobrazil.com\/en\/wp-content\/uploads\/sites\/3\/2022\/01\/lock-hair-shampoo-purple-background_185193-72096-300x200.jpg 300w\" sizes=\"auto, (max-width: 626px) 100vw, 626px\" \/><\/figure>\n\n\n\n<p>As we told you, sulfate-free <a href=\"https:\/\/metrobrazil.com\/products\/professional-step-1-shampoo-ph9-and-step-3-hair-mask-kit-by-sao-lindas?_pos=2&amp;_sid=d3d768f98&amp;_ss=r\">shampoos<\/a> will preserve your hair and keep your treatment for longer. These are already great reasons to start using them, but if you don\u2019t think that is enough, know that they also provide several other benefits. Take a look at some of them!<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"maintains-moisture-and-repairs-hair\"><strong>Maintains moisture and repairs hair<\/strong><\/h3>\n\n\n\n<p>If your hair has been coloured or chemically treated, use this shampoo to bring it back to life. Sulfate-free <a href=\"https:\/\/metrobrazil.com\/products\/professional-step-1-shampoo-ph9-and-step-3-hair-mask-kit-by-sao-lindas?_pos=2&amp;_sid=d3d768f98&amp;_ss=r\">shampoos<\/a> help your hair retain its natural hydration, so it retains its natural luster and smoothness.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"maintains-hair-color\"><strong>Maintains hair color&nbsp;<\/strong><\/h3>\n\n\n\n<p>Sulfate-free shampoos are a godsend if you have colored hair. These are gentler than their competitors and won&#8217;t strip your hair of its color as quickly. Sulfate-free shampoos are gentle on your hair, not only because they include hydrating agents, but also because they make your hair shine. Using a shampoo like this in conjunction with a conditioner can make your hair lustrous.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"reduces-itchiness\"><strong>Reduces itchiness&nbsp;<\/strong><\/h3>\n\n\n\n<p>Sulfates are harsh on the scalp and can cause itching and inflammation. Sulfate-free shampoos are gentler on the scalp and can help reduce inflammation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"tearless\"><strong>Tearless<\/strong><\/h3>\n\n\n\n<p>&nbsp;Sulfate-free shampoos are very soothing on the eyes. If you get a dab of shampoo in your eye, it doesn&#8217;t cause a painful burning sensation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"environmentally-beneficial\">E<strong>nvironmentally beneficial<\/strong><\/h3>\n\n\n\n<p>&nbsp;Sulfate-free shampoos are produced primarily from plant derivatives, making them environmentally friendly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"adds-moisture-to-the-hair\">A<strong>dds moisture to the hair<\/strong><\/h3>\n\n\n\n<p>&nbsp;Sulfate-free <a href=\"https:\/\/metrobrazil.com\/products\/professional-step-1-shampoo-ph9-and-step-3-hair-mask-kit-by-sao-lindas?_pos=2&amp;_sid=d3d768f98&amp;_ss=r\">shampoos<\/a> are great for hair with poor porosity, which means it has a hard time absorbing moisture. They keep your hair moisturized and frizz-free. Sulfate-free shampoos protect you from potentially harmful chemical compounds over time.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>After all this information, we can conclude that protein treatments and sulfate-free shampoos are a perfect combination.
