Okay, so I've been using this biotin-collagen-keratin supplement for about 2 months now, and I have THOUGHTS.
First off - the convenience factor is great. Just two capsules with breakfast, no weird aftertaste or chalky texture like some other supplements. Big win there.
Now for results: My nails? Definitely stronger. I used to break nails opening soda cans (embarrassing but true) and now they actually survive daily life. My hair feels thicker too - less shedding in the shower which is a major relief.
The skin benefits surprised me most though. I didn't expect much here but my complexion looks... glowier? Like that 'just got back from vacation' look without actually going anywhere.
Only downside - the first week I took it, my stomach was NOT happy. Had to switch to taking it with dinner instead of breakfast and that solved it. Maybe start slow if you're sensitive.
Overall? 4.5/5 stars from me. Not magic (still waiting on that unicorn hair growth serum), but definitely noticeable improvements where it counts.
