  • A new favorite?!
Style: Serum
I have only recently started using this scalp/hair serum but it is quickly becoming one of my favorite parts of my hair care routine. I have very thick, coarse, curly hair with some heat damage that is prone to breakage and I'm now on a healthy hair growth journey so a good serum is a must for me. The serum contains rosemary and caffeine, both ingredients that I look for in a scalp/hair serum. It has a pleasant smell that isn't overwhelming. The formula isn't sticky and doesn't make my hair feel greasy or weigh down my curls. Even after short term usage, my hair looks shinier and is noticeably softer already. My hair tends to get very frizzy, especially right after washing it and this has helped to maintain the frizz. I love the hot pink packaging and the applicator is convenient and very easy to work with. I look forward to seeing how this serum boosts my hair and scalp health and affects my hair growth/retention over the next few months! ... show more

My hair feels extremely soft!!! I have been using this line for some months now, all the products smell soooo great! And hair looks sooo shiny and beautiful! I love that they're vegan and cruelty free! Quality is superb! Price super on point! This one I can take with me on the go whenever I need it! Such a cute size! Excellent product! It is not sticky, it’s like silky, I am in love! 100% recommended! ... show more

  • Great product
Style: Serum
The bottle is relatively small but it comes with a convenient Pipette to apply the serum to the scalp. It’s smells really good and I had no trouble applying it. My scalp was itch free and moisturized. It will take a while to see if it helps with hair growth. So far so good

  • Unique Texture, Great Results
Style: Serum
This scalp serum has quickly become a staple in my nightly routine!! The texture is interesting and unlike any other hair serum I’ve tried, it’s slick but not oily, and it kind if reminds me of a skin ampoule. The scent is nice, though it is a bit too “cheap perfume-y” for my taste. The ingredients are outstanding for hair growth, and it feels great to massage into the scalp. Overall, I’ve really enjoyed incorporating it into my routine and look forward to seeing continued results! ... show more

  • Great for hair growth!
Style: Serum
I have noticed a nice change in my hair volume and length since using this product (I also use the other products in this line and I love them all!) I like how when I massage it into my scalp I can feel it and I don't see it and there is no build up even tho I put other products in my hair after this one and my scalp has never looked or felt greasy. The smell is pleasant but not over bearing! It's very easy to use but make sure you massage it into your scalp to get it deep into your hair follicles so it will show its true performance and best results! I'm not sure on leakage because I have mine upright In the cabinet behind my mirror but the quality is great and for the price you can't beat it! ... show more

  • ❤️❤️❤️
Style: Serum
I am thrilled with the Marc Anthony Grow Long hair serum! After using it for a few weeks, I’ve noticed a significant improvement in the condition of my hair. It has become smoother, stronger, and started growing faster. The pleasant scent and convenient dropper bottle make using the product a real pleasure. I recommend it to anyone dreaming of long and healthy hair! ... show more

  • Absolutely IN LOVE with this hair product!!!
Style: Serum
I use Grow Long Shampoo and Conditioner, with Grow Long Restoring Anti-Breakage Mask, and then occasional Marc Anthony Hair & Scalp Detox purify & refresh Shampoo. About every 3 weeks or so I would always oil my scalp and hair, and place a bonnet on to leave it all on overnight. I would always use Vitamin E oil, Tea Tree oil, Biotin Oil, Growth Oil, black castor oil, DooGro Mega Thick Formula Hail Oil, and African’s Pride Strengthen & Protect 5 Essential Oils with Vitamin E Oil. Then occasionally if my hair feels oily, or “dirty” waiting for my next wash, Creme Of Nature Argan Oil Strength & Shine Leave-in-conditioner is AMAZING and after it dries, it makes your hair look and feel like it was just washed. I also occasionally use African’s Pride Moisture Miracle Rose Water & Argan Oil Curl Mousse, African’s Pride Moisture Miracle Coconut Milk & Honey Leave-in-conditioner/ or Mielle Oats & Honey Soothing Leave-in-conditioner. So I was looking for a good oil/ hair treatment of Marc Anthony, since I absolutely love the way it helps my hair/ makes my hair feel using their Shampoo, Conditioner, and Hair Masks, and I stumbled across this, wanting to give it a try. I am IN LOVE with this product and so happy I purchased it. The hair serum is so “light” feeling that it not only looks amazing in your hair and will bring out the shine while helping any frizz, it FEELS AMAAZING!!! Anyone who uses any oil products know how it will make your hair look wet, and you can feel it all on your scalp and hair, that anytime you touch your hair, your hand will look and feel extremely oily. This DOESN’T do any of that. It makes your hair feel extremely soft immediately and you can’t feel it on your scalp or hair what so ever, that it’s like you didn’t even use an oil/serum. If you rub it on your hands before applying it to your hair, it also makes your hands feel very soft and doesn’t even make them feel like their is anything on them, to where you feel like you need to wash your hands immediately before doing anything else. I started using this as well as Marc Anthony Argan Oil ultra lightweight Exotic Oil Treatment, together, and I will never go back to anything else. They both are amazing in the way your hair will look, but also in how it will feel, as it makes your hair extremely soft, shiny, takes away any frizz, and it feels like you never even put anything on it, and just washed it that day. HIGHLY RECOMMEND giving it a try, if you never have and are wanting a really good hair serum/oil. To help make it even more over the top, I HIGHLY RECOMMEND using M. A Aragan Oil treatment at the same time of using this. ... show more

  • Hair serum
Style: Serum
The product smells good and I can’t wait to try it. But the box itself was like what looked to be ripped open or damaged as shown in the picture but the other stuff I got weren’t damaged and they were in the same bag. But the bottle its self was ok so that’s good.
