    Seems to be making a difference

    As a postpartum mom, losing my hair was extremely jarring and I lost a ton of confidence. As someone with fine hair, even after it started to grow back I still never felt like my hair looked the same. I started plated hair serum in August and am on my second bottle. It seems to be making a difference as I’m seeing more growth in the areas I lost a lot of hair postpartum. Hopeful that the progress continues!

    Plated Hair serum

    This is magic in a bottle. Since I started using plated hair serum my hair is incredibly healthy. The serum helped with shedding & my hair is growing so fast within just a few weeks. The change in my hair since I started the serum is unbelievable. It truly is magic in a bottle!

HAIR Serum

Frequently Asked Questions

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

HAIR Serum is a groundbreaking scientific achievement in hair and scalp science. Developed by Mayo Clinic physician-scientists and based on 20+ years of research, HAIR Serum is a breakthrough for at-home hair renewal.

HAIR Serum uses powerful platelet-derived exosome technology, fortified with antioxidants, phosphoproteins, and a proprietary blend of nurturing ingredients, to help improve the appearance of hair density, thickness, volume, and strength.

Who was ( plated ) HAIR Serum formulated for?

HAIR Serum is ideal for individuals experiencing hair-related concerns such as thinning hair, shedding, or lack of volume or density, as it helps improve the appearance of these issues. It's appropriate and effective for all genders, ages, and hair types.

How do ( plated ) platelet-derived exosomes support the scalp?

HAIR Serum harnesses the power of platelet-derived exosomes in a shelf-stable formula to regenerate the hair's look. Our exosomes come directly from platelets, the body's first responders for hair renewal.

Studies show that the platelet-derived exosomes in HAIR Serum can aid in helping the body set the stage for strong, healthy-looking hair. Our proprietary formula has been shown to improve the appearance of scalp coverage while increasing the look of volume, fullness, density, and thickness.

What is the key ingredient and mechanism of action in ( plated )?

The hero ingredient of HAIR Serum is platelet-derived exosomes, which deliver potent renewal technology to support the scalp and visibly improve hair density, volume, and thickness, while improving the appearance of scalp coverage. Other science-backed ingredients, including biotin, sea moss, hyaluronic acid, and turmeric, fortify HAIR Serum.

Are there any clinical studies supporting the efficacy of ( plated ) HAIR Serum?

Yes. In a double-blind, placebo-controlled clinical study of HAIR Serum, participants experienced remarkable results:

  • 100% of participants showed improvement in scalp coverage appearance
  • 96% reported improved appearance of volume and fullness
  • 3x improvement in the appearance of hair density
  • Visual improvement across 10 key hair health indicators
  • No side effects or downtime

How long does it take for exosomes to help renew hair? How quickly will I see results?

The platelet-derived exosomes in HAIR Serum get to work immediately on the scalp, but when it comes to hair, patience is key. Here's what you can expect:

  • 1–3 months: Exosome technology goes to work, reprogramming the look of the scalp and hair.
  • 4–6 months: The appearance of scalp coverage improves, and patchiness decreases.
  • 6+ months: Enjoy the look of your new fuller, thicker, healthier hair.

With regular use, the HAIR Serum helps maintain its benefits, making hair appear fuller, stronger, and thicker.

After I see results, should I continue to use ( plated ) HAIR Serum?

Yes, continued use of the HAIR Serum is recommended to maintain your hair's appearance. Regular application can help sustain the benefits and improvements over the long term.

Because platelet-derived exosomes support continuous renewal at the scalp, the longer you use HAIR Serum, the greater the benefits. In clinical studies, participants continued to see improvements in the appearance of thickness, volume, fullness, strength, and scalp coverage with continued use.

What are the ingredients in ( plated ) HAIR Serum, and how do they benefit my hair?

HAIR Serum is formulated by combining platelet-derived exosomes with an innovative blend of science-backed ingredients designed to boost the appearance of the hair's density, thickness, volume, and overall appearance. Check out the detailed ingredient list here:

  • Platelet-derived exosomes are nanosized vesicles that unlock the scalp's innate ability to renew for thicker, fuller hair.
  • Our innovative antioxidant blend helps reduce the appearance of hair and scalp damage due to emotional stress, sun exposure, and environmental pollutants.
  • Biotin inspires stronger-looking hair.
  • Hyaluronic acid conditions and hydrates your scalp.
  • Turmeric provides skin-calming properties.
  • Lindera strychnifolia root extract primes the skin on your scalp.

Is ( plated ) HAIR serum suitable for all hair types?

Yes, HAIR Serum is formulated to benefit all hair types. In fact, in clinical studies, 100% of patients of different ages and genders reported an improvement in the appearance of scalp coverage.

Why is ( plated ) better than other hair products on the market?

HAIR Serum is the first and only at-home cosmetic treatment to use the breakthrough power of platelet-derived exosomes. HAIR Serum is different in a few important ways:

  • Inclusive skincare for everyone: In clinical studies, HAIR Serum improved the appearance of scalp coverage for 100 percent of people across all ages, genders, and hair types.
  • Zero side effects: Participants in our clinical studies reported no adverse events. That's a stark contrast to other treatments that can have serious side effects for men and women.
  • Continuous exosome renewal: Platelet-derived exosomes work continuously to renew the hair and improve the appearance of density for fuller, thicker-looking strands.
  • The invisible-dry formula leaves no detectable residue, so you can style and go without heavy oils or foams weighing down your hair.
