I have been taking wellbel since January 2022. My hair is very fine, and hard to grow as my ends split easily. My hair was about shoulder length when I started and it is now past my collarbones (had multiple cuts in this time frame as well). This product definitely works. I have noticed baby hairs framing my face have grown out significantly, and my hair is definitely stronger. Even if I barely put product in my hair, air dry, and then style the next day, my hair actually looks good! I plan to continue taking these pills for at least another year for my wedding. I am so excited to see how it looks!
