## Questions & Answers

**Q: How to get the msds (material safety datasheet) for the product?**
A: Thank you for your question. 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
