Count the capsules! But so far so good
So far my eyelashes are growing like crazy and my hair stopped falling out. This is after one month. Still going to use it. But the bottle states it contains 120 capsules when in fact both bottles contained only 118. It’s supposed to be a 30 day supply so it leaves you short. I contacted Nutrafol customer support and they said they will mail me the missing ones. But I’m counting from now on. Hope this is a glitch and not on purpose to increase their profits.
I was hoping for a miracle !!!
I have been taking this product for 2 months and have not seen a noticeable change. I followed the instructions have taken 4 capsules each day and just nothing. It did not provide quick results, It didn’t stop thinning of hair or make my hair feel healthy. They don’t taste awful but also didn’t look forward to taking them. If I took them without food I wouldn’t feel so well and would get a headache. But now I am returning this product asap. I’d just rather go to my local pharmacy and grab some biotin pills. Deff not buying again.
It takes time to see results (or so I’ve read)
I have only been taking Nutrafol for close to a month, and I haven’t noticed any difference in my thinning hair yet. A couple of months isn’t long enough to see results either, as I’ve read it takes several months to a year before seeing visible results. The only thing that is a turnoff to me is that it is not a cheap product, and if I’m going to sink all this money into it I want to be absolutely sure I’ll see results. For now, I’m going to keep with it and try to be patient. It also has given me a headache at times, but not every time I take it. I take it with food as the instructions say to.
