    Magical Miracle Hair Serum

    I’ve been using Plated Hair Serum since ‘23 and have been a loyal fan since. Let me preface this with losing all of my hair after chemotherapy in 2017 and working so hard at trying to grow it back ever since. I tried everything and it took so long for my hair to grow - my nurse mentioned Plated to me and said her husband had been using it and couldn’t believe his hair growth at 58, so I had to try. In about four weeks I had so much new baby hair growth and fullness, I was hooked.

    I now using Plated Hair Serum as part of my hair maintenance, only about 3x per week, a few drops around my scalp and gently massage it in and go to bed.

    IYKYK and if you don’t, then you MUST try it.

    This works!!

    I’m on my fourth bottle I think?? I’ve been struggling with thining hair around my temples. I’m a lady with crazy think hair but after a bout with anemia, b12 deficiency plus perimenopause, I needed help! I tried all the shampoos, pills and everything else but this returned my hair to is glory and I have zero complaints!! It’s pricey but so worth it!!

    Light weight

    The formula is light weight and easy to use. Just started a month ago but hope I get the same results as other plated products.

    Still early!

    I’ve only been using for a few weeks. I don’t love the dropper. Hoping it’s still effective!

    Reversed traction alopecia!

    I wish I would have done a before and after but I have used this for 6 months and it totally reversed my traction alopecia from years of wearing too tight a top knot. Love this product

    It seems to be helping

    A friend told me about this and she has been using for over 6 months from chemo and she says it’s amazing. Her hair is thick and crazy. I have scarring alopecia so I’m desperate in trying to save my hair. I’ve only been using for 3 months and I think I can see some benefits. I’m gonna keep using til year end for sure as hair don’t grow in a day and if it’s working I’ll be a regular customer.

    IT WORKS!

    I was skeptical because of the price, but the (plated) Skin Science Hair Serum actually works. The lightweight, invisible formula doesn't feel greasy or weigh my hair down. By week seven, my part looked visibly denser and fuller. It is an investment, but the exosome technology delivers real results

    Easy to use, not sticky, drys fast. Been using for a few weeks and noticed more coverage. Hoping to continue to see results.

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.
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
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.
