SO GOOD!
Perfect for growing out your hair or lashes! I really started to see a difference in as quickly as a week or two. Make sure you do eat with them to avoid stomach ache.

Ideal capsule size
The capsules are the perfect little size! They're very convenient to take, especially if you're taking other vitamins and don't want to take a huge handful.

The Secret to Hair That’s Basically Made of Unicorn Magic
Let me tell you something: Thorne Biotin 8 is not just a supplement. It’s the key to unlocking your inner glam god/goddess. If you've ever wondered why your hair isn't flowing like a shampoo commercial model or why your nails keep breaking after just one casual wave, THIS is the answer. After taking these magic little pills for a couple of weeks, my hair is now so thick, shiny, and luxurious, I swear it’s got its own gravitational pull. I step outside, and it practically starts waving to people on its own. If Rapunzel had these on hand, she would’ve been out of that tower in no time—and her hair would have been way healthier. And don’t get me started on my nails. Before Biotin 8, they were brittle, sad little things that could barely handle opening a bag of chips. Now, they’re practically indestructible. I could probably use them to scrape ice off my car, open a coconut, or fight off a bear at this point. They’re that strong. My skin? Let’s just say I no longer need a ring light to look like I’ve got perfect, glowing skin. I’m literally glowing in real life, no filter required. I’ve never looked so fresh, I’m convinced I’m secretly a 22-year-old model, and this is my skincare routine, but I won’t tell anyone my secret (you’re welcome). So, if you're ready to give your hair, skin, and nails the level-up they deserve, do yourself a favor and try Thorne Biotin 8. Your reflection might not even recognize you after a few weeks. Just be prepared for the constant compliments and questions like, "Did you just walk out of a beauty ad?" Because yes. Yes, you did.

Noticing new hair growth
I started noticing new hair growth about half way through this bottle. I only took one a day. Actually skipped it for several days here & there. My hair tends to grow super slow so any new growth is exciting. It’s not in the place I want but I guess beggars can’t be choosers. It’s coming in on front side area and in the back. I’m going to order another bottle today and see what happens with it. Nails seems to be stronger as well. Haven’t noticed hair growing anywhere else it shouldn’t be. Overall good product I would recommend it.

No difference in nail health
I like Thorne vitamins. I didn't see any benefit from this particular one though.

WOW... this works
I've been using this for 2 years and my hair is amazing. One note is that my hair is curly now. Beautiful wavy curls. But, I can straighten if I want, but I've never had such fullness. I get compliments daily. I also use Thorne's collagen. My neice finished chemo for the 4th time in 7 years and I started her on it...it is growing like crazy and thick AF!! also curly lmao

Complément efficace pour les cheveux en cure de 2 mois minimum

I started taking Thorne Biotin 8 to help with weak nails and dull hair, and I’m finally seeing results after a few weeks. My nails feel sturdier, and my hair has a noticeable shine. It’s easy to swallow and doesn’t upset my stomach, which is a plus. That said, it’s not an overnight fix—you need to be consistent to see real improvements. Also, if you’re expecting major changes to your skin, the effects are subtle at best. Overall, it’s a solid choice if you’re looking to boost your hair and nail health with a trusted brand.

Another hit from Thorne. SO good. I notice a marked difference when I take versus weeks of not taking.
