A must-have daily treatment if you’re searching for the best hair growth serum to support thicker, stronger hair.

PeptiBoost contains peptides for hair growth and copper peptides. Copper peptides help stimulate hair follicle stem cells and support collagen and elastin production, strengthening the scalp and encouraging hair regrowth. By improving follicle health and circulation, they also help reduce hair thinning and promote fuller, thicker-looking hair.
Caffeine stimulates blood flow to the scalp, rosemary oil supports scalp health and reduces inflammation, and hydrogenated castor oil helps hydrate hair while reinforcing the hair shaft for stronger, healthier strands.

After a full year my hair has grown in and is about 4 inches now
The peptide hair serum has helped me grow hair all over my head!! Everywhere i put the serum, every morning & night, has started new growth. It's taking a little while for the new hair to grow to a length that looks good, but it's constantly growing longer!!
My hair started growing in after 6weeks. It's still growing in, I just have to make sure and use it evenly and everywhere everyday. I hope once it all grows in, i don't have to use it everywhere and everyday to maintain it.
Seriously! Ive left many reviews for this product and I STILL absolutely LOVE it. Its amazing! Definitely worth the price and it lasts a long time! I have a LOT of hair and it lasts me at least a month and a half using it every other day! Definitely definitely worth it!
I tried this product when I received it in my Ipsy bag. I had to buy it!! It makes such a difference with my baby fine hair. I am so glad I found this brand and highly recommend it.
i shaved an undercut months ago and regretted it immediately. got this in a subscription box, and LOVED IT so i got the full size 50 ml bottle. my hair has grown an inch in 2 weeks, my curls are softer and easier to separate, and my scalp DOES NOT ITCH. [i also ordered another product that did not arrive and i was refunded so easily and they responded so quickly so 10/10 5 stars 4eva]
I got the mini version from Ipsy and ran out if it super quick so I knew I had to get the big one and it’s amazing!! It makes my hair so shiny and healthy 💗💗💗
This Serum is the best starting with the non grassy part. I just apply a small amount and massage my scalp with it and just do my blow dry as fast as I can and I barely notice frizz. I feel that does my routine faster that usually takes. Is my 2nd time used so far and very good Serum. Love it!
Ok I picked this product as my choice in my IPSY bag. I came to this page to find it. I placed a drop on my scalp and it just felt like changing. The way it made my scalp feel as though all the bad stuff was removed and only clean and fresh tingling was left. I had to keep my hands from using more than it said. I honestly felt if I dumped the entire bottle on my head it would remove all the trauma. How can I make my scalp and hair feel like this all the time. I don't see much change yet in volume, but I have only used 3 times counting today. I have seen less frizz. Please let me know if you have a product that feels this amazing to my entire scalp
