I've had good results with Biotin. It does take a couple of weeks to start working, or at least it did for me. :)
I'm constantly pulling out handfuls of hair after every brushing. I started taking biotin because I heard many women sing it's praises. I haven't noticed anything yet.
I recently started using Monat hair care products. I have seen a huge difference in my hair. I am seeing new growth and less dryness - which all started due to the PCOS
I started taking hair vitamins had to go through a few different ones before I found one that worked to help my hair grow thicker and fuller and it stopped me from losing so much hair it's called Hairfluence I bought it on Amazon.
Thanks
