Pack Cheveux et Ongles - 1 pot + 3 éco-recharges | Apporte force et brillance | 4 x 21 jours

The 5000 μg of biotine per gummy is exactly what my hair needed—three weeks in and my nails are noticeably harder and my hair feels thicker when I brush it. The 4 x 21 days format means I never run out mid-cycle, which is perfect since I hate repurchasing constantly.

I was skeptical about gummy supplements, but the 5000 μg biotin dose here is hard to beat. The eco-refills are a clever touch too—less waste, which I appreciate. My nails feel noticeably harder already, and that's after just the first pot.

After three weeks of taking these gummies along with my usual routine, the little ridges on my thumbnail are finally smooth and my hair doesn't snap off when I brush it. The eco-recharges are a genius move too—I just refill the jar and skip the plastic waste.
