    A beautiful change

    Since starting the Plated Hair serum I have started to feel a texture change, softer less frizzy hair. I’m seeing and feeling stronger strands and new growth. All the Plated products are amazing and so easy to use. With consistent use all the products will make a beautiful difference.

    LOVE THIS. VERY IMPRESSED

    I have been incredibly impressed with Plated Hair. I am 44 years old and I have always had thin hair. As I am again i need some help. My hair feels healthier, stronger, and noticeably more vibrant since adding it to my routine. My hairdresser is in shock! What stands out most is the overall improvement in the quality of my hair—it feels softer, its shinier, and has that healthy, resilient feel that is difficult to achieve with styling products alone.

    I appreciate that Plated focuses on hair health rather than temporary cosmetic fixes. The difference feels real and cumulative, with my hair looking better week after week. Even my fine hair appears fuller, with more movement and life.

    Like the rest of the Plated line, the quality is exceptional. The science, formulation, and results have made me a loyal customer. It's rare for a product to exceed expectations, but Plated Hair absolutely has. One of the most exciting additions to my hair care routine, and I look forward to continuing to use it.

    Worth it

    I had severe hair loss from some surgery. Within a week of using this my hair fall was significantly, noticeably reduced in the shower. It took about 3 months to start seeing the new growth, but now that is also very significant. I am on month 4 and continuing to see the same improving results. Will definitely keep using if just to prevent the hair fall in the shower!

    My hair had started to thin a bit around my crown and in my part, but my hair is noticeably thicker, denser, and healthier after using this serum every wash night for the past two months. Even though the price point makes me wince, this hair serum is now a forever product for me!

    It’s helping!

    Recommended by my dermo, now on month 3 of Plated Hair Serum (alone) for inherited female MPB/thinning and those thinnest spots are filling in! Took a couple months but it works better for me by itself, without finasteride or minoxidil. Plus so pleasant & easy to use and leaves a great hair texture behind, wet or dry. This science is the end of bald spots and the future of hair care, far as I’m concerned. Next best thing to using my own stem cells.

    Too early to tell

    It’s easy enough to apply but too early for me to see results

    It really works!

    I had been slow to buy this even after knowing how great the intense serum works and let me tell you, this hair serum is amazing!! It says give it 90 days however even after 60 days, I’ve got new growth! My stylist even asked “Where’s all this new growth coming from?”. I shared my secret! It’s pricey but worth it!!

HAIR Serum

Frequently Asked Questions

What is ( plated ) HAIR Serum and how does it work?

( plated ) HAIR Serum is a groundbreaking scientific achievement in hair and scalp care, the first platelet-derived exosome technology designed to deliver powerful nutrients to the scalp.

The proprietary blend of platelet-derived exosomes found in Renewosome® technology is formulated into a serum clinically proven to help make hair look fuller, stronger, and thicker.

The ( plated ) HAIR Serum supports the scalp by delivering a growth factor complex and powerful antioxidants to the skin, setting the stage for your hair to look and act at its absolute best.
Who was the HAIR Serum formulated for?

The HAIR Serum is ideal for individuals experiencing hair-related concerns such as thinning hair, shedding, lack of volume, or those seeking to improve their hair's overall health and appearance.
How quickly will I see results from using ( plated ) HAIR Serum?

By using the HAIR Serum, you should start noticing improvements in the appearance of your hair, including density, strand thickness, shine, moisture, reduced breakage, and overall healthier-looking hair within weeks.

Consistency is key to seeing results as quickly as possible, and full results typically develop over 3-6 months with continued use.

With consistent use, the HAIR Serum helps maintain its benefits, making hair appear fuller, stronger, and thicker.
How long should a bottle of HAIR Serum last?
  • Each bottle of ( plated ) HAIR Serum contains 90 pre-measured dropperfuls, enough for a 3-month supply when using one dropper per day.
  • Depending on the size of the area you're targeting, you may need more than one dropper per day; in that case, the bottle may last approximately 2 months.
  • The dropper is intentionally pre-loaded to about half full as you unscrew the cap; there's no need to pull up more. That's plenty of product to spread across several targeted areas.
  • For optimal results, apply directly to the scalp rather than the hair, as this promotes easier distribution and improved absorption.
Why is ( plated ) better than other hair products on the market?
  • Our HAIR Serum is the first platelet-derived exosome technology designed to deliver a powerful growth factor complex and nutrients to the scalp. The serum works like a fertilizer by priming the scalp, creating an ideal environment and providing the essential antioxidants necessary for thicker-looking hair. This innovative approach targets hair challenges at a cellular level, unlike many other products that focus on superficial treatment.
  • ( plated ) HAIR Serum is the first-time patients have been able to use platelet-derived exosomes at home for hair. There are a few botanical exosome serum products on the market for hair, but we know the source of exosomes is the most critical element. Our Renewosome® technology is a patented process that ensures only ( plated ) offers platelet-derived exosomes in our at-home, prescription-free products.
  • The technology found in our skincare serums and increases the concentration of platelet-derived exosomes to the highest concentration of any of our products. We then combine that with natural ingredients that can help to further reduce the appearance of hair and scalp damage.
