Visibly thicker after 2 months — stylist noticed

I'm on my fourth pack and my hair is visibly thicker and growing faster. My stylist noticed new growth at my 3-month appointment. The Capilsana Complex with MSM and horsetail seems to add something extra beyond plain biotin. Nails are stronger too. One thing to know: hair grows faster EVERYWHERE — underarms, legs — so be prepared for that.

Growing back where it's supposed to

After almost 4 years of trying to grow my hair back from thinning, Hairfinity is the supplement that actually showed results. I can see hair retention and growth in the areas where I'd given up hope. The collagen + biotin combination in one pill means fewer supplements to juggle. Been taking these consistently for 6 months and I'm not stopping.

Made me break out and feel constantly hungry

Two unexpected side effects: my face and chest broke out in acne (the biotin was too strong for my skin), and I felt ravenously hungry all the time — gained about 8 pounds over a few months. The hair growth was real — I could see it — but the side effects weren't worth it for me. My mom tried the same pills with zero side effects and great hair results. Depends on your body.
