First time mom... wasn't aware how bad postpartum hair loss could get. 3 months in... and it was a lot and it wasn't letting up, so glad I found Baby Blues but I’m a bit of a vitamin nerd so I decided to do my research.Pros: Baby Blues vitamins have 6000mcg of Biotin, that’s a healthy dose and kinda guarantees this isn’t a placebo effect. If this doesn’t get your hair growing you may need to see a Doctor regarding thyroid issues etc (many blogs I've read suggest thyroid issues can be common after delivery) . Biotin (aka B7) stimulates keratin production and will increase the rate at which your hair grows. Not only is there biotin, but there’s collagen too. Collagen is the protein that serves as one of the main building blocks for hair. Baby Blues is different in that they use marine collagen which is the highest bioavailable collagen. That’s great, but if you’re vegan, this will be a con. Folate for healthy hair growth, pantothenic acid for anti-stress hormone regulation, zinc for hair tissue growth and repair. I was really impressed with the other vitamins present in Baby Blues. It's a team of vitamins rather than just a biotin gummy. It’s a pectin gummy made from the cell walls of fruit, so none of the chemicals that come with gelatin. It’s “candy good”, that might be a con too, because I’d like to take more than 2 of these a day. I like that these are made in an FDA certified facility in the USA. Amazon is full of gummies from China that don’t have the same standards. Many of the ones outside the US are cheape,r but as a new Mom i'm not taking the risk -- I only purchase US made vitamins.Cons: Ok, it’s a bit pricey, but getting my hair back on track is worth it. This vitamin saves me from having to buy 3-4 different vitamins and boosts my skin and nails at the same time. I’m not complaining. Again price comes with the made in USA tag typically. It’s not vegan. I’ll forgive this too, because I want it to work, and again marine collagen is known to absorb the best.All in all, this is one of the best vitamins I’ve taken which is why I’m giving it 5 stars. I’m weeks in and I’m starting to see baby hairs sprouting again. I get it will be a few months before I really start to see the benefits (vitamins take time to show results) and they recommend at least 3 months to see significant change but I can already tell with my hair. I’m relieved and very happy I found Baby Blues and will recommend them.
