Several things in your daily routine can set the tone for your day. It could be getting a good night\u2019s sleep, drinking your favorite caffeinated beverage or styling your hair like it\u2019s fresh from the salon. These small things may be overlooked sometimes as mundane rituals, but they can boost your mood every day. <\/strong><\/p>\n\n\n\n

In my experience, a good hair day can make all the difference in making me feel more confident and put\u2011together. And so, when COSRX\u2019s first\u2011ever hair care line hit the market, I couldn\u2019t wait to try it. With all the glowing reviews promising silky, shiny and frizz\u2011free locks, I had to see for myself if the brand\u2019s PEPTIDE-132\u2122 collection is worth the hype or just another gimmick.<\/p>\n\n\n\n

The PEPTIDE-132\u2122 hair care line includes the Peptide 132 Ultra Perfect Hair Bonding Shampoo<\/a>, Peptide 132 Ultra Perfect Hair Bonding Treatment<\/a> and Peptide 132 Ultra Perfect Hair Bonding Oil Serum<\/a>. Curious to find out whether these hair care products deliver on their promises? Read the full review below!<\/p>\n\n\n\n

What is PEPTIDE 132\u2122?<\/strong><\/h2>\n\n\n\n

K-Beauty<\/a> brand COSRX<\/a> has earned cult-favorite status among beauty fans, including the YesStyle Editors<\/a>, for its science-backed and result-driven formulas. Its patented PEPTIDE-132\u2122, touted as \u201cthe world\u2019s only keratin\u2011bonding solution<\/a>,\u201d repairs broken structure in hair and seals in long-lasting moisture. Unlike other hair care products that offer only temporary and surface-level care, COSRX\u2019s patented hair care ingredient contains low\u2011molecular\u2011weight tripeptide that deeply penetrates the hair shaft to\u00a0nourish and repair both the hair cuticle (outermost layer of the hair) and cortex (thickest, middle layer of the hair).<\/p>\n\n\n\n

Aside from PEPTIDE-132\u2122, the hair care line is also enriched with seven plant-based oils to enhance hair\u2019s shine, as well as ceramides and hyaluronic acid<\/a> to deeply hydrate locks. Hydrolyzed protein, low-molecular collagen and 18 types of amino acid strengthen weak tresses and minimize hair breakage.<\/p>\n\n\n\n

Peptide 132 Ultra Perfect Hair Bonding Shampoo<\/strong><\/a><\/h2>\n\n\n\n

Main ingredients: <\/strong>PEPTIDE-132\u2122, hydrolyzed vegetable protein, low-molecular collagen, 18 amino acids, biotin, panthenol, niacinamide, tocopherol, ceramides, hyaluronic acid, natural oils like macadamia seed oil<\/p>\n\n\n\n

The Peptide 132 Ultra Perfect Hair Bonding Shampoo<\/strong><\/a> instantly improved my hair\u2019s texture from the very first wash. I was genuinely amazed by how quickly the results showed up after rinsing off the shampoo. My hair felt noticeably softer and smooth, to the point where I could easily glide my fingers through it even while it\u2019s still damp.<\/p>\n\n\n\n

Whether your hair is chemically treated, heat-damaged or dry from frequent sun exposure, this low-pH and deep cleansing shampoo can restore your hair\u2019s strength and shine, while leaving your scalp clean, fresh and grease-free.<\/p>\n<\/div><\/div>\n\n\n\n

After shampooing, gently squeeze excess water from your hair before applying an appropriate amount of the Peptide 132 Ultra Perfect Hair Bonding Treatment<\/a> to your mid-length and ends. For deeper nourishment, leave the product on for about 10 minutes before rinsing off with water. This\u00a0wash\u2011off hair treatment\u00a0<\/a>pairs perfectly with the Peptide 132 Ultra Perfect Hair Bonding Shampoo<\/a>, as they\u2019re both formulated with hair-strengthening and nutrient-restoring ingredients like collagen, amino acids and biotin to reduce hair breakage and restore that glossy shine from root to tip.<\/p>\n\n\n\n

Peptide 132 Ultra Perfect Hair Bonding Oil Serum<\/strong><\/a><\/h2>\n\n\n\n

Main ingredients: <\/strong>PEPTIDE-132\u2122, Vitamin E, seven botanical oils (including olive, argan, camellia seed, jojoba, rice bran, macadamia seed and grape seed oils)<\/p>\n\n\n\n

The ultimate hair-bonding and repairing routine is not complete without the Peptide 132 Ultra Perfect Hair Bonding Oil Serum<\/a>. This is the hair product you reach for when you want to give your locks that effortlessly glossy and bouncy look. However, the shine-restoring hair serum comes in a thick and tacky formula, which may not be everyone\u2019s cup of tea. Nonetheless, it still feels lightweight without leaving any greasy residue. You can apply the hair serum on damp or dry hair to protect it from heat styling tools and lock in all-day hydration.<\/p>\n\n\n\n

Final Thoughts<\/strong><\/h2>\n\n\n\n

So is COSRX\u2019s PEPTIDE-132\u2122 hair care lineworth the hype or just another gimmick? I’m happy to report that the PEPTIDE-132\u2122 range absolutely lives up to the buzz! After using all three products together and letting my hair air dry (a.k.a. no styling), it gave my hair a naturally glossy and bouncy look. On days when I blow-dried my hair, the healthy, mirror\u2011like shine became even more noticeable.<\/p>\n\n\n\n

My hair is naturally wavy with lots of volume toward the mid\u2011lengths and ends, which can be both a blessing and a challenge. But with COSRX’s PEPTIDE-132\u2122 product lineup, my hair felt easier to manage. I was able to achieve smooth, soft and frizz\u2011free locks. I recommend using all three products together to achieve the best results.<\/p>\n\n\n\n

The only downside? The\u00a0price tag. It\u2019s a bit much for me, so I think I\u2019ll be saving the three products for\u00a0special occasions\u00a0when I want my hair to look its absolute best. That said, if budget isn\u2019t an issue, this hair care trio could easily replace your regular salon blowout and give you professional\u2011level results in the comfort of your own home. Glass hair<\/a>? Oh we absolutely know her, and that\u2019s all thanks to COSRX\u2019s PEPTIDE-132\u2122 hair care line!<\/p>\n","protected":false},"excerpt":{"rendered":"
