My hair is past my shoulder blades, and trying to wrap a full section around a barrel meant for someone with a bob has always resulted in the same outcome: the bottom half of my hair dangles loose, the top kink-curls weirdly, and by the time I&#8217;m done with the back of my head the front has already drooped. Then the <strong>Bio Ionic Long Barrel Styler<\/strong> showed up on my doorstep with a 6.5-inch barrel, and the entire problem disappeared.<\/p>\n\n<h2 class=\"wp-block-heading ww-advertorial__heading\"><a href=\"https:\/\/www.amazon.com\/Extended-Moisture-Technology-NanoIonic-Versatile\/dp\/B01J248HWM?tag=hyphen-brit-base-20\" rel=\"sponsored nofollow noopener\" target=\"_blank\">Meet the Bio Ionic Long Barrel Styler<\/a><\/h2>\n\n<p class=\"ww-advertorial__para\">It&#8217;s a 1.25-inch curling iron built specifically for people with long or thick hair. The barrel is roughly two inches longer than a standard iron \u2014 enough room to actually wrap a real section in one pass. It uses Bio Ionic&#8217;s NanoIonic MX heat technology, which infuses negative ions into the hair while you style (read: it&#8217;s gentler on the cuticle). Six temperature settings up to 430\u00b0F. Heats up in about 22 seconds. Long 9-foot cord.<\/p>\n<aside class=\"ww-advertorial__product ww-advertorial__product--single_hero\"><img decoding=\"async\" class=\"ww-advertorial__product-image\" src=\"https:\/\/media.ulta.com\/i\/ulta\/2576060?w=600&amp;h=600&amp;fmt=auto\" alt=\"Bio Ionic Long Barrel Styler 1.25&quot; Curling Iron\"><div class=\"ww-advertorial__product-body\"><h3 class=\"ww-advertorial__product-name\"><a href=\"https:\/\/www.amazon.com\/Extended-Moisture-Technology-NanoIonic-Versatile\/dp\/B01J248HWM?tag=hyphen-brit-base-20\" data-merchant=\"Amazon\" rel=\"sponsored nofollow noopener\" target=\"_blank\">Bio Ionic Long Barrel Styler 1.25&#8243; Curling Iron<\/a><\/h3><p class=\"ww-advertorial__product-description\">Extended 6.5-inch barrel, NanoIonic MX heat technology, six heat settings up to 430\u00b0F.

The waves came out even \u2014 the same shape at the top as at the bottom, which is somehow a thing I had stopped expecting. They also held. Through a full day. Through an evening dinner. The next morning I still had loose, soft bends in my hair, which is unheard of for me.<\/p>\n<blockquote class=\"ww-advertorial__quote\">My hairdresser told me about this gem and it&#8217;s worth every dime. I&#8217;ve never been good with curling irons in the past but this one gives the best beach waves that last.<cite>Emily, 5-star reviewer<\/cite><\/blockquote>\n\n<h3 class=\"wp-block-heading ww-advertorial__heading\"><a href=\"https:\/\/www.amazon.com\/Extended-Moisture-Technology-NanoIonic-Versatile\/dp\/B01J248HWM?tag=hyphen-brit-base-20\" rel=\"sponsored nofollow noopener\" target=\"_blank\">And my hair actually feels okay after<\/a><\/h3>\n\n<p class=\"ww-advertorial__para\">This is the part I really didn&#8217;t expect. Curling irons usually leave my ends feeling crispy, but after six weeks of regular use my hair feels exactly like it did before I started \u2014 soft, shiny, intact. NanoIonic MX is apparently doing something real, not just selling words on a box.<\/p>\n<blockquote class=\"ww-advertorial__quote\">It makes my hair feel super soft and it glides right through the barrel.<cite>Katie, 5-star reviewer<\/cite><\/blockquote>\n\n<h2 class=\"wp-block-heading ww-advertorial__heading\"><a href=\"https:\/\/www.amazon.com\/Extended-Moisture-Technology-NanoIonic-Versatile\/dp\/B01J248HWM?tag=hyphen-brit-base-20\" rel=\"sponsored nofollow noopener\" target=\"_blank\">A few things to know<\/a><\/h2>\n\n<p class=\"ww-advertorial__para\">It&#8217;s not the cheapest curling iron on the market \u2014 Bio Ionic sits in the salon-tier price bracket. And the 1.25-inch barrel is built for soft, voluminous waves, not tight spiral curls. If ringlets are your thing, you want a smaller gauge. If you&#8217;ve been Googling &#8220;beach waves that actually last,&#8221; this is the one.<\/p>\n\n<h2 class=\"wp-block-heading ww-advertorial__heading\"><a href=\"https:\/\/www.amazon.com\/Extended-Moisture-Technology-NanoIonic-Versatile\/dp\/B01J248HWM?tag=hyphen-brit-base-20\" rel=\"sponsored nofollow noopener\" target=\"_blank\">Bottom line<\/a><\/h2>\n\n<p class=\"ww-advertorial__para\">If you have long hair and you&#8217;ve been making excuses for the curling iron you already own, this is the upgrade. Two inches of barrel is the whole difference and somehow it&#8217;s the entire difference.<\/p>\n<aside class=\"ww-advertorial__methodology\">\n<h2 class=\"ww-advertorial__methodology-title\">Why trust Brit+Co<\/h2>\n<p>The Brit+Co editorial team curates each pick based on hands-on testing, expert input, and reader feedback.
