Lighter in composition, the protein smoothing treatment does not leave hair extremely straight, it just leaves it frizz-free and very soft!<\/p>\n\n\n\n<p>Besides not altering the natural look of the hair, another advantage of this type of treatment is that it lasts a long time! It is usual that the effects become apparent 4 to 6 months after the protein smoothing procedure is done. Amazing, isn&#8217;t it?<\/p>\n\n\n\n<p>A wonderful example of protein smoothing treatment that can be done both at home and in the salon is the Real Brazilian Hair Protein line, by the Brazilian brand <a href=\"https:\/\/blog.metrobrazil.com\/en\/meet-riobelo\/\" target=\"_blank\" rel=\"noreferrer noopener\">RIOBELO<\/a>! Made of natural ingredients, it can be found in the <a href=\"https:\/\/metrobrazil.com\/collections\/hair-products\/products\/3-steps-professional-real-brazilian-hair-protein-kit-by-riobelo-acai-for-dyed-hair-1l\" target=\"_blank\" rel=\"noreferrer noopener\">a\u00e7a\u00ed version<\/a> (for blonde or dyed hair) and in the <a href=\"https:\/\/metrobrazil.com\/collections\/hair-products\/products\/3-steps-professional-real-brazilian-hair-protein-kit-by-riobelo-maracuja-for-normal-and-curly-hair-200ml\" target=\"_blank\" rel=\"noreferrer noopener\">passion fruit version<\/a> (for all hair types), the 3-step line guarantees soft and healthy hair in a matter of minutes!<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2598\/9598\/products\/200_fce57749-bba3-4dc9-8362-b2af240a700a_2000x.jpg?v=1616847010\" alt=\"\" \/><\/figure>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>KERATIN TREATMENT<\/strong><\/li><\/ul>\n\n\n\n<p>As the name implies, a keratin treatment is essentially composed of keratin, the most common protein in hair. With the goal of making the hair soft AND straight, this type of procedure makes use of formaldehyde in most cases, which can cause damage to your health.\u00a0<\/p>\n\n\n\n<p>Furthermore, a keratin treatment can be done both at home (usually using products with lighter formulas) and at the salon. In general, the process consists of creating a kind of keratin barrier around the hair, making it more resistant! In addition, to &#8220;activate&#8221; the keratin, it is necessary to use a hairdryer and a flat iron.&nbsp;<\/p>\n\n\n\n<p>The durability of the keratin treatment varies from product to product, but the average is around 3 months! In other words, you will have soft and straight hair for a considerable time.&nbsp;<\/p>\n\n\n\n<p>A tip for a keratin-based product line that can be used at home is the <a href=\"https:\/\/metrobrazil.com\/collections\/hair-products\/products\/nazca-professional-hair-care-kit\" target=\"_blank\" rel=\"noreferrer noopener\">Professional Reconstruction line<\/a> by the Brazilian brand Nazca! Safe and efficient, you will notice all the differences in your hair after using it.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2598\/9598\/products\/kit4_2000x.jpg?v=1624660185\" alt=\"\" \/><\/figure>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>INDICATION<\/strong><\/li><\/ul>\n\n\n\n<p>Both treatments are suitable for all hair types. However, you may find specific treatment lines on the market for a certain type of hair!
