Being a popular hair\nproduct, it is important to understand its shelf life so as avoid wastage or using\na harmful expired product.<\/p>\n\n\n\n<p>Read on to learn if hair shampoo does expire, how\nto tell it\u2019s out of date, how to check and read expiration date codes and the\nside effects of using it in a stale condition.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Does Shampoo Expire?<\/strong><\/h2>\n\n\n\n<p>Yes, similar to perishable and\nprocessed goods, shampoo as well expires. The only unfortunate thing is that\nsome of these products will not indicate to its customers on the due date. <\/p>\n\n\n\n<p><strong>Why?<\/strong><\/p>\n\n\n\n<p>Well, adding expiration dates is a\nmandatory requirement by the FDA, Foods, and Drug Administration, who only\nregulate food items. Beauty products, hair care essentials, and personal items\nand accessories are not therefore controlled by them, hence not mandatory to\nadd dates to the product. <\/p>\n\n\n\n<p>Luckily, some brands will add the\nmanufacturing and expiration dates out of courtesy. It could be in any of these\ntwo ways;<\/p>\n\n\n\n<ul><li>Period after opening (PAO)<\/li><li>Expiration codes<\/li><\/ul>\n\n\n\n<p>You shall read about these two methods shortly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is Shelf Life of Shampoo?<\/h2>\n\n\n\n<p>Shelf life refers to the <strong>period of use<\/strong> of a particular product &#8211; how fresh a product is before it turns stale. For food items like milk or bread,\u00a0 their shelf life could be one to five days.<\/p>\n\n\n\n<p>But for shampoo, they last even up to three years. This, however, means that the product has used a substantial amount of preservatives to make it stay that long. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"700\" height=\"449\" src=\"http:\/\/hairsentry.com\/wp-content\/uploads\/2020\/01\/hair-shampoos.jpg\" alt=\"Hair Shampoo photos\" class=\"wp-image-2383\"\/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">How to Determine the Shelf Life of Shampoo<\/h3>\n\n\n\n<p>As mentioned earlier, many brands\nwill add a <strong>period\nafter opening mark<\/strong> to indicate just how long the product can remain\nfresh and usable once it&#8217;s exposed to the environment. <\/p>\n\n\n\n<p><strong>How\nto Find the Mark<\/strong><\/p>\n\n\n\n<p>Look at the bottle on the lower side\njust under the instructions or next to the scan bar &#8211; you will see a picture of\na container with a number inside. The mark mostly lies in the right-hand corner\nof the shampoo bottle. <\/p>\n\n\n\n<p>The number indicated in the\ncontainer is the number of months it can remain usable until it goes stale. The\nnumber could read 3, 6, 9, 12, or 18.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What\nFactors Determine the Shelf<\/strong> <strong>life of the Shampoo?<\/strong><\/h3>\n\n\n\n<p>Several factors that could either\nfavor or expedite the shelf life of shampoo. They include;<\/p>\n\n\n\n<p><strong>Type of shampoo<\/strong> <\/p>\n\n\n\n<p> Not by a difference in brands but the nature of the shampoo. Is it natural or manufactured? Many people love to use natural products and remedies for their hair, but they tend to expire faster than the processed kind. This is because they have no added preservatives or additives. <\/p>\n\n\n\n<p><strong>Type of packaging<\/strong> <\/p>\n\n\n\n<p> creams like shampoos packed in bottles have a shorter shelf life than sprayed-on dry shampoos. Aerosol shampoos contain alcohol, which not only makes it stay longer, but being in a spray can &#8211; they also have minimal exposure to air.<\/p>\n\n\n\n<p>Bacteria will, therefore, not be spread by people touching the shampoo now and then, leaving it fresher for longer.<\/p>\n\n\n\n<p><strong>Environmental exposure <\/strong><\/p>\n\n\n\n<p> you will open the shampoo one time after you buy it. But what increases or decreases its shelf life is where you store it after it&#8217;s open. If you consistently leave it in the bathroom where there are high levels of humidity &#8211; it may go stale faster. Most manufacturers will indicate that it&#8217;s to be stored in a cool, dry place.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Do You Know If a Shampoo is Expired?<\/h2>\n\n\n\n<p>Here&#8217;s a scenario where your shampoo\nbottle doesn&#8217;t have any expiration code, no period after opening mark, or\nanything to indicate its shelf life. What next? <\/p>\n\n\n\n<p>In most cases, there&#8217;s always a way\nto smell a rat, literally. The shampoo will give off some signs to indicate\nthat its past due it&#8217;s usable time. Here are some ways you can know if your\nshampoo has expired;<\/p>\n\n\n\n<p><strong>1.\nThe smell of the Shampoo<\/strong><\/p>\n\n\n\n<p>When most products go stale, they\ngive off an unpleasant or strange odor. That&#8217;s also similar with shampoo. Many\nof you will opt for a shampoo that has a strong lavender scent so when your\ndone cleaning your hair, it maintains that scent. <\/p>\n\n\n\n<p>Well, to know if the shampoo has\ngone stale, the lavender scent will decrease or flatten completely. Meaning you\nwon&#8217;t even smell anything. Worst case, it might smell awful. <\/p>\n\n\n\n<p><strong>2.\nChange in Color<\/strong><\/p>\n\n\n\n<p>Next up, the color. Again with the\nsame example, your shampoo could have a green hue, probably because it&#8217;s fresh\navocado shampoo. After the due date, the shampoo could start changing color to\ndark green or even black. <\/p>\n\n\n\n<p>The bolding of color from its\noriginal hue indicates that the preservatives have outlived their shelf life,\nand now the shampoo is decomposing. It&#8217;s probably best to throw it out.<\/p>\n\n\n\n<p>This, however, is not a 100% sign\nbecause some products tend to change color upon exposure to air or sunlight, so\nif you&#8217;ve not stayed long with the shampoo, it&#8217;s probably still okay to use. <\/p>\n\n\n\n<p><strong>3.\nNature of Reaction<\/strong><\/p>\n\n\n\n<p>Soap, shampoo, and other cleaning\nagents are meant to lather when water is added. If your shampoo fails to create\nfoam, it could be another sign. This also goes hand in hand with the need to\nuse the shampoo more often than usual because the results are unsatisfactory.<\/p>\n\n\n\n<p>When the shampoo goes bad, it means\nthe active ingredients in the product no longer work. Hence, it may not clean\nyour hair as effectively as it used to. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Read Shampoo Expiration Date Codes<\/h2>\n\n\n\n<p>Another way you can determine the\nshelf life of shampoo is through the expiration date codes. These are\nalphanumeric models written or engraved on the bottle to indicate how long the\nshampoo will stay fresh. The cryptic code will contain batch codes that\nindicate when the product was manufactured, so you can not only test the\nauthenticity of the product but also estimate it&#8217;s due date.<\/p>\n\n\n\n<p><strong>1.\nCode One<\/strong><\/p>\n\n\n\n<p>The first type of code is the <a href=\"https:\/\/sunridgefarms.com\/wp-content\/uploads\/2017\/04\/Julian-Code-Sheet.pdf\">Julian date code<\/a>. This is a seven-digit code found at the back of the box\nthat is used to trace back the manufacturing date of the product. <\/p>\n\n\n\n<p>A sample of this code is 0801424 &#8211; the first three numbers (080) point to\nthe day of the year it was produced. That is around March 20th\/ 21st. The next\ntwo digits will indicate the year, and the final two for the batch number. This\ncode then translates to March 21st, 2014, batch number 24.<\/p>\n\n\n\n<p><strong>2.\nCode Two<\/strong><\/p>\n\n\n\n<p>Another method used by brands is\nsubstituting alphabets for months. For example, A stands for January, B for\nFebruary and so on. The next numbers following the letter will indicate the\nyear. For example, D14 &#8211; April 2014.<\/p>\n\n\n\n<p>No matter how often this code is,\ndeciphering the code may be difficult than you presume. This is because, in\nsome cases, C doesn&#8217;t automatically mean March. There&#8217;s an insequential pattern\nwhere F is for May, H &#8211; June, K &#8211; July, M &#8211; August, R &#8211; September, T &#8211; October,\nV &#8211; November, and X &#8211; December.<\/p>\n\n\n\n<p><strong>3.\nCode Three <\/strong><\/p>\n\n\n\n<p>In some cases, there&#8217;s six-digit\ncode, which denotes MMDDYY. This is also a prevalent code used even by the FDA\nto add to food items. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">FAQs<\/h2>\n\n\n\n<p>Now let&#8217;s see some of the commonly\nasked questions. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is it Safe to Use Expired Shampoo?<\/h3>\n\n\n\n<p>Safe is rather a far fetched word to\nuse. It&#8217;s not safe to use the expired shampoo because the added preservatives\nand additives could change course for worse. The chemical compound could\nchange, causing adverse effects to your hair and scalp.<\/p>\n\n\n\n<p>However, the effects of using\nexpired shampoo may not weigh anything. Meaning it simply won&#8217;t do its work on\ncleansing the hair. Even so, its is unsafe and unhealthy to use expired shampoo\non your hair&nbsp; <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can Expired Shampoo Cause Hair Loss?<\/h3>\n\n\n\n<p>In rare cases, you may experience\nhair loss. This is greatly attributed to the chemicals used to manufacture the\nshampoo. You may know that&#8217;s there are different types of shampoo &#8211; for deep\ncleansing, getting rid of oils, or light pooing kinds. <\/p>\n\n\n\n<p>For the strong kinds like deep\ncleansing, the chemicals may cause you to experience severe effects on your\nhair from a change in hue to even hair loss. It is, however, not guaranteed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does Expired Shampoo Cause Itchy Scalp?<\/h3>\n\n\n\n<p>Yes, it does. Most shampoos are calming,\nwhich is why they can also condition the hair. But when you use the shampoo\npast its dates, the ph balance will be off-balance making it more basic or\nacidic. This then causes you to have more dandruff on your scalp, and\nconsequently, an irritated or itchy scalp.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does Shampoo Expire If Unopened?<\/h3>\n\n\n\n<p>It depends on the type of shampoo,\nbut the clear answer is no. For most period-after-opening kinds of\nshampoos,&nbsp; the chemical elements in the\nproduct remains balanced and safe as long as it has not yet been exposed to the\nenvironment. So if left unopened, then it&#8217;s expiration isn&#8217;t even a factor to\nconsider.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does Shampoo Go Bad in Heat?<\/h3>\n\n\n\n<p>Yes, heat tends to cause reactions to chemicals. They\ndecompose, degenerate,&nbsp; and even rot with\nextended periods of exposure to sunlight. This is why some shampoos will turn\ncolor, smell, and also expire due to oxidation that limited the abilities of\nthe preservatives. Either wa, store in a cool, dry place for better results.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A shampoo is one of those beauty items that most ladies cannot stay without.
