Nourish your scalp. Strengthen your roots. Support healthy, fuller-looking hair!

Our EternalTW Hair Growth Serum is powered by a blend of advanced peptides, natural extracts, and vitamins designed to give your hair the care it needs from the root up.

Key Benefits:

  • Stimulates and strengthens hair follicles with Myristoyl Pentapeptide-17 & Biotinoyl Tripeptide-1
  • Supports thicker, fuller hair with Saw Palmetto (Serenoa Serrulata) extract
  • Deeply hydrates scalp & strands with Glycerin, Sodium Hyaluronate, and Vitamin E
  • Helps reduce thinning appearance and promotes a healthy scalp environment
  • Lightweight, non-greasy formula — perfect for daily use

How to Use:

  1. Apply daily — Apply dropper of serum directly onto dry scalp, focusing on thinning or target areas.
  2. Massage in — Use your fingertips to gently massage for 1–2 minutes to boost absorption and stimulate circulation.
  3. Leave on — Do not rinse. Style your hair as usual.
  4. Use twice daily for best results. Once a day for steady growth. 

Timeline to Expect

Consistency is key. Results may vary by individual, but here’s a general timeline of what most users experience:

Weeks 1–4:

  • Scalp feels more nourished and hydrated
  • Reduced dryness and flaking
  • Early support for healthier roots

Weeks 4–8:

  • Hair begins to feel stronger and less prone to breakage
  • Thinning areas look fuller as new growth cycles begin
  • Improved overall scalp environment

Weeks 8–12+:

  • Noticeably thicker, healthier-looking hair
  • Increased density and volume in targeted areas
  • Long-term support for stronger, more resilient hair

I do believe this product is helping me fill my hair back in. It has been a struggle the past 5 years from getting covid and being postpartum at the same time I love this formula as it does not give your hair an oily feeling . Cant wait to watch my hair keep feeling in!

Customer video review of Hair Growth Serum

I’m on a glp and started noticing my hair thinning. I’m also in post menopause so it can be a side effect of aging as well but I’m on my second bottle of the hair serum and LOVE it! I’ve already noticed a difference in the top of my hair and I love how the serum doesn’t make my hair oily and I even use it right after washing to boost hair growth.

I am loving my Eternal Hair Serum. It’s easy to apply, one full dropper once a day on dry hair. I love that this product does not leave my hair greasy after applying. I have seen a difference where my hair starts looking like a V it actually looks fuller.

My hair was very thin at the temples so I decided to try the Hair Growth Serum. Week two I swear there were tiny hairs growing in! Now after several months I can tell a big difference in the thickness on both sides. I use it once a day now and truly love this product!

I have noticed some you know quite a bit of a hair growth. I had breast cancer and head radiation therapy and that is one of the side effects of hair loss. So it is helping me substantially regain that back thank you Carrie Gibson.

Customer photo review of Hair Growth Serum

After one month, I'm shocked. I have an autoimmune disorder that causes hair loss. And to see my hair looking fuller after just one month is incredible. But more so than anything else, I have sores on my scalp. I've had dandruff my whole life. I haven't had that in 2 weeks. After 2 weeks of using Eternal Hair Growth Serum, the sores on my scalp cleared up and I haven't seen a flake! Eternal, you've done it again! And it's clean and nontoxic so I don't have to worry about what I'm absorbing through my scalp. 10/10 RECOMMEND!!!!

ETERNAL is an amazing Christian, family-owned company with outstanding customer service. I love supporting a company that honors Christian values while creating such high-quality products. My favorites are the toothbrush and toothpaste, lip balm, lash growth serum, eyebrow gel, and SPF moisturizer, which is perfect for the Florida sun. My teeth have never been so white, and I loved the toothbrush so much that I bought one for everyone in my family! Highly recommend ETERNAL—10/10!

Did not work for my hair thinning problem. I like that this is waterbased and lighter than other oils that are supposed to promote hair growth. So I really wanted this to work for me, but after 8 months I haven't seen any new hair growth where my hair was thinning on the top of my head. I used it twice a day every day.

Hair Growth Serum

Second bottle!! Love the results AND my hair stylist asked what i am using and she order some too!!
