I have been struggling with hair thinning for a while now, since my early 20s. I found out later on that i had PCOS, which was causing my hair to thin out. I was also experiencing a lot of hair fall out, which makes it even more obvious that I was thinning at the top of my scalp. I became very self conscious and obsess with my hair, trying to grow it back. After reading many reviews about irestore laser, I decided to give it a chance. I mean why not, if it doesn't work you can always return it within 6 months. It would be a good investment if it did work because I was wasting money on a lot of hair growth serum and hair grow supplements that didn't seem to make a difference. While using the helmet, there were times I wanted to expedite the process and use it almost every day (6-7 days a week). After 3 months, I did notice less shredding in the shower. My hair looks fuller at the top compared to before.
