I have been taking them for 2 weeks and I am excited to say that I see growth already. I have braids, the last set I took out I had a lot more growth than I had seen in the past. I think it was because I had increased the amount of raw veggies and protein I was eating. But Hairfinity is the reason I notice growth in two weeks.
I had already started drinking tons of water in preparation of the vitamins so I haven't yet noticed any side affects like acne.
To combat the smell I take 2 vitamins out and leave them on my dresser to air out for the next day. It makes taking the vitamins bearable.
So far I love it and as long as I don't have any problems I am going to keep taking them.
