body{margin-left:12%}Product ReviewsRated 4.61 out of 5 stars119 ReviewsMost Helpful Positive ReviewPretty GoodThis is a pretty nice serum. The formula is fairly thin and not at all sticky. It can look a bit oily on the hair if you use too much, but that's easy to avoid once you play around with it. I did feel like it added a little shine to my hair, and it definitely made it feel softer and encouraged my curls (3a/3b). I took off a star because I really don't like the smell. To me it smelled like baby wipes. Maybe it just didn't mix well with my other hair products or something, but yeah, I wasn't a fan, though I could see how other people might like it.Most Helpful Critical ReviewAmazing but breaks outI love this product. My hair is soft and shiny; even after I wash my hair after using this you can still feel the difference. The problem is the fragrance. If you have sensitive skin at all you cannot use this. IT WILL DESTROY YOUR SKIN. I only use this for important events but I suffer the consequences after. It takes about 2 weeks for my skin to go back to normal. It makes my neck, chest, back, cheeks, anywhere my hair touches break out HORRIBLY! Really hoping they make a fragrance free version but I won't/can't purchase this product again. ;(Reviewed by 119 customersSmells HEAVENLY5Lainey from Roseburg, ORMakes my hair smooth and shiny and i LOVE the smellGreat hair oil4Tiff from WaI love this alot. Good frizz reduction. Smells so goodLightweight5brookeh68 from undisclosedI have fine wavy hair which means serums are a must in humidity but can easily weigh my hair down. This is proven to be lightweight and build able. It will continue to be one of my go tos.Not for extremely frizzy hair2Lola from MinnesotaMy hair is beyond frizzy (i use about 3-4 products for frizz and it still is horrible). This didnt do anything for me. I will say it smells AMAZING. If your hair gets somewhat frizzy i could see it potentially working for youReally nice for curly hair5Faithie from Atlanta, GAI like to use this after my curls are mostly dry and it makes it look reallt shiny and bouncy. I like the texture, has a strong hold for the end of curls, like if you were to use this oil to twirl the ends, it would lool great.Works well4Nikki from USAI have wavy medium thick hair. I dont use much products or color treat my hair. I use this typically after a shower and apply when damp. I think it works best like that. When i apply to dry hair it gives off an oily look im not a fan of. I am noticing that my hair is softer and less tangly then when i dont use it. I wish it did a little more for the frizz but overall i would recommend.Literally amazing!!5Annie from MarylandThis is my holy grail hair product! I have very fine, straight, color-treated hair that is usually flat and frizzy the next morning after sleeping on it. With this, I can wash and blow dry at night, and my morning hair is still soft, shiny, and sleek!I love it!5Sunshine from IndianapolisThis hair oil is so pleasantly light scented and is wonderful for my thin, dry frizzy hair. Love the pump bottle (one pump is perfect for me) and product isn't heavy as some oil tends to be. So glad I took a chance with this and will definitely purchase again.It does not weigh down your hair5cute_as_ducks from undisclosedI love this product it is very reasonable priced. It's not expensive like the Lanza healing oil is. I think it does just as great as a job for half the cost. A little goes a long way. I put it in my ends of my hair everyday. I love the smell too.Pretty good!4BD30 from undisclosedMy hair is so fine it gets touchy with really any kind of extra product. I've used other Kristin Ess products in the past and they have been pretty good for the price — this one just isn't right for my hair. For those with thicker hair I think it would work great!Best serum I've used in a while!5 from Greenwood DEMy ends tend to get dry but this leaves my hair so soft! I use it after I wash my hair (mostly on the mid-ends, little on the rest of my hair) before I dry it, then also after styling only on the ends to give shine and moisture.Soft & Smooth5Mos from Sacramento, CALove this serum for my dry hair. Put some life into my hair, add shine and smoothness.Great serum5Brenda from NJI just tried the serum for the first time and it's awesome! I've been having a dry, frizzy hair issue for a while and have tried many products without success. This works!!!! My hair is soft and shiny.Great benefits!4MissPrissTexas from Denton, TXI'm glad I tried this Kristin Ess serum. It's beneficial. I use it on wet and dry hair. It adds some shine to my hair. When using it on my wet hair, I don't quite like how it makes my hair feel. However, once I dried my hair, it feels normal. I like using it on my dry hair for my nonwash hair days of days 2 and 3. It helps smooth it out and adds some shine. It's a good consistency. It doesn't weigh my hair down or make it feel greasy. Doesn't really have a scent.Very smoothing5Magda from PAI use this serum on my damp hair from the middle to the tip. It is SO SMOOTHING. I blow dry my hair and the effect is amazing: shiny, healthy looking hair. And you don't need to use a lot of the product. Just few drops.Yes. I will used again again. My favorite5Lien from Grand Prairie TXGood productAffordable hair serum4T Marie from NYThe Kristin Ess Weightless Shine Serum is a good option if you're looking for an affordable hair serum and the scent is pleasant. My hair is fine and the serum was light enough to even use between washes to treat my dry ends.Wonderful light serum5Chaya from NyThis serum is wonderful. It's light and works gently on the hair, making it silky and soft without leaving a residue at all. I was looking for something to add moisture to my hair without adding an oily feel and this serum worked beautifully. I've used it on wet hair after a shower and also on dry hair when I'm ready to go out but my hair is just a bit puffy.Smooth Hair5KayC from GeorgiaI was able to try out this product for a sampling campaign and I am impressed. After blow drying my hair I put some of this in my hair before styling and it makes it so smooth. My hair looks great for days.Works great5Ironicfoxes from ChicagoThis serum is super nice and easy to work with. I like using it affer I curl my hair to keep it shiny. It's lightweight and doesn't feel so greasy or gross. It also works for keep your pony tail shiny and cuteLove!5Beej from Austin, TXMy hair LOVES this Weightless Shine Working Serum from Kristin Ess. I have quite thick, curly hair which is notoriously prone to frizz and dryness. After the first use with this Working Serum, I immediately noticed less frizz; after a couple uses, my hair is definitely more smooth, moisturized, and shiny. Couldn't recommend enough if you need a little moisture/shine/anti-frizz boost to your locks!Beautiful Hair4MomMommaMommyMa from TennesseeI really enjoy how light Kristin Ess Weightless Shine Working Serum feels when I put it in my hair. A lot of other brands are a lot thicker and heavier feeling which I hate. My hair always looks rejuvenated once I have used this serum.Super nice5Wagarific918 from Manahawkin, NJI received Kristin Ess Weightless Shine Working Serum to try. I love the box that this comes in, it is a very nice and good quality looking box. The bottle is perfect and a great size. I love this serum as it was easy to dispense and easy to apply. It left a very nice shine without making a heavy feeling.Beautiful shiny results!5lorloo from undisclosedThis shine serum works great for my hair. While my hair is still damp I apply a liberal amount to my hair and then blow dry. The results are spectacular. My normally fine listless hair has great volume and is very shiny.Adds Shine!5tinicflo from Portland, ORThis product is great. Especially for on-the-go/fast mornings. A little spray adds shine to your hair. Also makes it easy to create a good, quick wet look. Every time I use it, I get compliments on my hair. I have really wavy hair that can turn static/frizz in the mornings. This has really helped tame it without spending a lot of time. Have a feeling I will use this long after this bottle runs out.
