Hair Thickening Serum

Is your hair thinning? Are you experiencing hair loss?

There are many factors that may be involved when looking at the causes of hair loss. Some of the more common causes are family history, hormonal changes, medical conditions, medications, chemotherapy, stress, hairstyles, poor nutrition, aging, or significant weight loss. 

NeoGenesis hair care products return to the adult those nutrients once created in abundance during our youth that slow down as we age. We deliver those nutrients in a way that works within your hair’s normal growth cycle.

NeoGenesis Hair Thickening Serum is specially formulated for those with fine or thinning hair. It uses the most advanced science to add noticeable body, shine, and density. NeoGenesis Hair Thickening Serum is the first to combine the benefits of the stem cell, S²RM® Technology with potent antioxidants, peptides, and other innovative stem cell nourishing ingredients to recondition the scalp and hair follicles.

Our patented exosome-based system delivers stem cell released molecules (SRM) from four adult stem cell types to hair follicles to produce noticeable cosmetic benefits. This potent combination of growth factors and other signaling molecules offers a non-invasive alternative, or complement, to conventional treatments by harnessing your body’s own naturally occurring regenerative mechanisms to make your hair look and feel healthier and stronger.

    “It’s my second purchase of this serum. I have thinning hair on the temples and this serum is definitely helping. There are more sprouts of new growth that wasn’t there before but it takes 1 1/2 or 2 months to see. One bottle lasted me 2 1/2 months and I mostly use it only on concerned areas, but some days I apply on bigger area of scalp because it’s very soothing. I’m excited to continue using it and see continuous results! Beautiful product ❤️” ~ Skin Beautiful RX

    “Yes. This Hair Thickening Serum works!! I am having the same result. Thicker, dense hair. On top of that, my itchy scalp (maybe was eczema) is not bothering me anymore.❤” ~ @nativisskincarecc

    I used the product daily and noticed a change in hair growth in the affected areas within five weeks. The bottle formula is easy to dispense and apply, with no side effects or unpleasant sensations. I noticed that my hair became softer and curlier on the product (I have curly hair though the last few years it has become straighter with hormonal changes), which delighted me. When the new hair began to grow in, I saw that it was per the areas I was treating – the temples on both sides and the middle of the head along the hairline. I would certainly use this product again and would be interested in continuing treatment with it. It has been the only product I’ve used that actually demonstrated hair growth, something I was skeptical of initially but then felt surprised and impressed when I realized that it was working. ~ MS

    It Works
    “I do not have hair loss, I purchased this product to reverse premature greying, which it did not do :( HOWEVER I was astounded by how much thicker, denser, and longer my hair got in a very short period of time. I will repurchase this product because of that. But like seriously I’ve had people ask if I got hair extensions, it was a dramatic improvement to my already healthy hair.” ~ B – Christine Byer Esthetics

    “It’s my second purchase of this serum, I have thinning hair on the temples and this serum is definitely helping. There are more sprouts of new growth that weren’t there before but it takes 1.5 or 2 months to see.

    New Growth
    “I have an “M” shaped hairline and noticed that it seemed to be receding on each side of my forehead. So far, I’ve used almost 1 entire bottle and already have new growth in the areas that looked bare. Also, I used it on dry hair (instead of wet as instructed) and it still worked!” ~ KR – Art of Skin Care

    Solved my Alopecia
    “I am a Black woman with lupus. As a result, I have experienced alopecia that exposed quarter-sized bald spots on my scalp. I also experienced general thinning. using this product has resulted in the bald spots filling in completely so well that I can no longer tell they were there. A lot of the thinness I had has vastly improved. I love this product and I would recommend it to anyone.” ~ T – Art of Skin Care

    Holy Grail

  22. Kelsey Butler

    “I have tried this product for just a short while but I have already noticed results. My hair is longer and most importantly for me, it’s definitely a little thicker. I like this product and will continue to use it. It’s on the high price end but it seems to be working just fine so far and in my opinion, it’s definitely worth it.” ~ S – Skin Beautiful RX

  23. Kelsey Butler

    “You guys … I believe in this product. I’ve used two bottles and feel that some of my very problematic areas (that crack in the hair on the back of my head in the morning, and at my sparse temples and front hair line are less of a problem. I’m about to purchase my third bottle. I go through a bottle pretty fast, and the price tag makes me absolutely cry, but I really think it’s good stuff. I will always have this.” ~ C – Skin Beautiful RX

  24. Kelsey Butler

    “I haven’t been using this long enough to see major results. That being said, I can see some baby hairs turning up which is new growth. So far, so good.” ~ S – Skin Beautiful RX

    “I use the hair serum every night…I went to my dermatologist a couple of months ago…My doctor said…You’ve got a lot of new hair growth…what are you doing? I told her about NeoGenesis Hair Serum…She asked me again when I left the name of the product…and wrote it down…I’ve used many products on my hair…This is one I can honestly say works.” ~ MP – Christine Byer Esthetics
