Glans, kracht en volume: het complete ritueel

My hair stylist actually asked what I'd changed after I used this through a week of beach vacation and pool swims. The biotin dose is strong enough that I noticed my nails getting harder too, which was a bonus I didn't expect from a hair routine.

After two weeks of taking the biotin every morning, I've noticed way less breakage when I brush, and my hair feels thicker at the roots, which is a big win after all those beach days.

I was skeptical about combining internal and external care, but the biotin dose is solid and my hair feels less brittle after the summer pool season. Only reason it's not 5 stars is the packaging could be more practical for travel, though the results are definitely there.
