Essential Source Biotin (Biotina Vitaminas) - Hair Skin Nails Vitamins for Women & Men - 5000 mcg - Hair Growth Support Supplements - 90 Tablets - with Revytalyz 5, Vitamin A, C, B12 - Made in USA

I never write reviews, but I have to share how truly amazing the product is. I struggled unexplained hair shedding for over a year, and no hair vitamin made a difference. I’m talking like a handful of hair every time I brushed it. Now I brush my hair and only a few strands fall out. It made a HUGE difference. I am also seeing so much new growth. I highly recommend you try this vitamin! I will say, it took 2 months of taking the vitamin every day to see a difference. I’m so glad I stuck it out to see these amazing results.

Love love love this! My hair is growing tremendously and it feels great.

Going on 10 weeks and yes I recommend!!!!! I do take 5000mg along with Collagen and I am pleased!

I thought it was effective when I first starting taking it but not as good as other hair vitamins that I’ve tried.

As I've had so much hair loss from taking medications, I've tried several hair-growth supplements over the past 5 years. This one is definitely the most effective. After 6 months, my hair is thickening even though I'm still having some hair loss from use of meds. This was recommended to me by a health food store worker in Vermont as the best available. He was right! Make sure to purchase the one with 5000 mcg of Biotin, not 3500.

I purchased specifically for nails and hair. Since Covid, I let my nails grow out. I had gel powder for over 20+ years and since they no longer have gel, they split and chip and just won't grow. I'm on my third bottle and my hair seems fuller and a bit thicker but it hasn't done anything for my nails. I will continue taking it, as sometimes it takes longer than a few months to notice a difference.

I take this every day for yearsMy hair is thick and niceMy nails are strongI’m 62 and my hairdresser said she didn’t know how my hair has stayed this nice 👍

Only product that I've tried which strengthen my nails and get them to grow. I've struggled with weak and peeling nails my whole life, Bonita V is the only other product that has worked for me. I've tried paint on nail protein, 6 pills of collagen, prenatal vitamins after pregnancy, nothing works as well as this product. I have a farm so my nails get a workout daily. This product allowed me to finally have nice nails without them being broken down to the skin, or peeled off trying to do up a horses bridle or girth.
