Non greasy science backed ingredients all around 10/10
I was lucky enough to get a sample of the Marc Anthony Grow Long Scalp & Hair Serum in my Ipsy bag a few months ago, and I immediately fell in love with it, especially the price tag. As someone with fine, thin hair, I am always hesitant to use serums or oils for fear of it looking greasy, but this one is perfect. It adds a beautiful shine without weighing my hair down. Beyond the fact that it doesn't leave my hair greasy, it also smells absolutely divine! I've been using it for a couple of months now, and I can honestly say I've noticed a difference. My overall scalp and hair health has improved, and I've even seen some new growth around my hairline. I also love to use a little bit of this on my ends when they look a bit dry. It's so hard to find a product that works for my hair type, but this serum truly is a game-changer. I will definitely be repurchasing it!

My Everyday Hair Essential – Stronger, Healthier, and Never Greasy
I absolutely love this serum! I use it every single day, and it has truly made a difference in my hair. I have fine, thin hair, and this never makes it look or feel greasy—which is amazing. Instead, it absorbs quickly, feels lightweight, and leaves my hair soft, shiny, and full of life. Since I started using it, my hair has been better than ever. It feels stronger, healthier, and I’ve noticed far less breakage. I honestly can’t go a day without it—it has become a staple in my routine. The serum is easy to apply directly to the scalp, and a little goes a long way, so the bottle lasts a while. If you’re looking for a product that nourishes, strengthens, and keeps your hair looking its best, I highly recommend this one!

Absolutely IN LOVE with this hair product!!!
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.

Basic Hair Serum - no results yet
I recently started using this hair serum after I had severe hair loss from high-chlorine/hard water in my shower. I really like the smell of it, but it seems a little on the watery side instead of oily. I do one full squeeze on each side of my scalp followed by a basic scalp massage to get all the product spread out, but I don't feel like it's being fully absorbed by my scalp and hair. I've been using it for about two weeks now, and I apply it every other day. Haven't seen dramatic results yet.

If you overdo it, it can feel a bit heavy, so start light
I’ve been a fan of Marc Anthony products for years, and this Grow Long Scalp & Hair Serum has officially earned its spot in my Florida humidity-proof lineup. What I Love: Incredible value compared to high-end salon brands — seriously, it delivers at a fraction of the price. A little goes a long way. If you overdo it, it can feel a bit heavy, so start light and build if needed. My color-treated hair loves it — it feels stronger, smoother, and noticeably fuller from root to tip. Yes, it actually adds natural shine without feeling greasy. Florida-tested and approved: it holds up beautifully against frizz and humidity. Real Talk: No, it’s not a miracle potion, but for the price and performance, it might as well be. It’s like giving your hair a pep talk and a protein shake all at once. This one’s a small bottle with big impact. If you’re looking for strength, shine, and smoother days ahead, this might just be your new favorite serum in the fight against breakage and the frizzies.

Good product, not good for oily hair
Noticed growth within a month, 3 stars because consistency is off, very watery but still leaves my hair a little oily

I've only just started using this miracle oil, primarily to prevent breakage as I am suffering from heavy shedding in these dry Canadian winter months. I've only just received it within the last week or so, and with daily usage I can say it is life altering for me. If I go even one day without an application my scalp will revert back to feeling irritated and inflamed, with premature breakage and heavy shedding. This elixir leaves my hair soft, shiny, and healthy without that weighed down or greasy feeling. It is absolutely a protectant against breakage; my drain was clogging regularly before and I am noticing vast improvement in the shedding area. I absolutely adore this product and recommend as a topical treatment for scalp irritation or treatment, not merely for hair growth. It really is that potent.

Me regalaron una muestra y la use por no dejar y me sorprendió bastante, me crecieron bastantes cabellitos en zonas que casi no había y esos mismos siguen creciendo, llevo unos 4 meses usándolo regularmente y el crecimiento de esos cabellitos va unos 5 cm de largo además de continuan apareciendo "baby hairs" en varias zonas.

I can't say this actually makes your hair grow faster or longer quicker, but it definitely makes hair very, very soft, shiny, and silky. I'm actually surprised. The scent is a bit on the potent side, but does fade away after a while. I use this mostly on dry hair in the evenings and sometimes on damp, washed hair. So far, my hair feels strong and very soft and looks shiny and healthy after use. Overall, this product seems to me more artificial than a castor oil or some rice water sprays, but I have had good results when using, so I may purchase it again. For the price, it's definitely worth trying.
