You can find what you need by visiting this link: https://chemmanagement.ehs.com/9/947674d3-d158-49c3-b902-52ef45099bc9/ebinder/?nas=True **Q: I received product that is thin, runny. Takes 4 or 5 pumps to have anything of substance to apply to hair. Is that the way it is supposed to be?** A: I had only used this product 1 time. I always shake the bottle to “mix” the product. I now use the viviscal gorgeous growth densifying leave in elixir. It does not take a lot of the product and is a liquid serum. I have used viviscal for two years now on a daily basis. (I had lost almost 80% of my hair and being almost bald after I had Covid. I also take the hair vitamins, use the shampoo and conditioner. My hair is back to the pre Covid episode and I see new growth daily (I call them sprigs until they get some length to them!) And may I add you have to use this product daily to really see results. For me it was about 4-5 months before my scalp was not showing! I continue to use it because of the way my hair looks and feels. Sorry for the long answer but this product worked miracles for my hair loss situation. **Q: Does anyone see a difference between the old product and the new product?** A: Thank you for your question. Here is more information on the Viviscal Hair Thickening Serum:· Increased quality of the formula· Added marine collagen and seaweed extract· Increased the conditioning and film forming properties that added benefits such as density, softness, manageability and anti-frizz· NEW scent that is not as over-powering and has a watery floral fresh, it is a clean signature scent. It is delightfully radiant with its lush greens, dewy florals, juicy fruits, and hints of ocean breeze. **Q: how many times can you use 1 bottle till it runs out?** A: I really can't answer that question fairly but I have short, thinner hair and am surprised how a couple of squirts does the job and 1 bottle lasts me around 2 months ## Customer Reviews ### ⭐ Made my hair even more frizzier… *by A***R on 9 September 2024* Don’t advise for curly hair ### ⭐⭐⭐⭐⭐ Does what it says, thickens thinning hair *by A***R on 26 May 2026* This serum really helps to thicken my thinning hair, but you have to use it every time you wash your hair, although just a few drops does the trick. ### ⭐⭐⭐⭐⭐ It volumizes and makes my hair look Bountiful *by L***I on 13 August 2023* This works really well to make your hair look bountiful. After Covid. I lost a lot of hair. The hair that came in was baby fine and did not take well to styling. This product helped to volumize my hair. It does have a distinct scent, but it is not objectionable. It feels clean and does not weigh my hair down. I do not like having conflicting smells between body lotion, perfume and hair product. Once you blow dry your hair the scent significantly lessens. Moreover, most people don't come up to smell your hair and you can't smell it from standing distance. It does make my hair look and feel better which considering the amount of hair loss, this has helped my confidence. ## Frequently Bought Together - Viviscal Hair Thickening Serum, Instant Lightweight Hair Product, Leave-in Elixir for Thicker, Fuller Looking Hair, with Keratin & Biotin, 50ml (1.69 fl. oz.) - Viviscal Thickening Shampoo, Formulated With Biotin And Keratin, Fortified With Marine Collagen And Seaweed Extract, Strengthens And Reduces Breakage, Healthier Looking Hair 250ml (8.45 fl. oz.) - Viviscal Hair Strengthening Conditioner – Strengthens and Reduces Breakage for Fuller, Healthier Hair – With Biotin, Keratin and Marine Extracts – 250ml (8.45 Fl Oz) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/599099910-advanced-hair-thickening-leave-in-serum-with-keratin-biotin-marine](https://www.desertcart.hr/products/599099910-advanced-hair-thickening-leave-in-serum-with-keratin-biotin-marine) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-15*
