If you're noticing hair shedding, thinning strands or abnormal hair loss, the first step is to call a board-certified dermatologist to rule out any serious health issues. After that, know that you're not alone. Hair loss can be triggered by a variety of factors such as hormonal swings, stress and medications or even harsh hairstyles and products. I've got good news though: there's no shortage of over-the-counter treatments and supplements that are expert-approved and backed by rigorous clinical testing (in some cases for decades) to help, and many of them are conveniently available on Amazon.

We researched which hair growth products on Amazon are getting the best ratings and reviews by real users. Ahead, the ones that have impressed them the most and why.
