I have experienced hair loss for about 4 years now. It began with a receding hairline, followed by overall thinning on top. I am interested in knowing which treatments help and which do not, so I can deal with my own hair loss in the most effective and convenient manner. There seem to be mixed opinions and controversy both in the medical community as well as those experiencing hair loss about the effectiveness of "low-level laser therapy" marketed for hair loss. As a result, I want to personally try out this treatment for myself. My rationale for testing laser therapy specifically: First, it is a non-drug treatment with no known side effects. It would be awesome if it actually works. Second, there is uncertainty and controversy surrounding its effectiveness, so I want to determine once and for all if it works. And third, there have been some studies suggesting it may have results for men with male pattern baldness (e.g., http://onlinelibrary.wiley.com/doi/10.1111/dsu.12200/abstract), so it may be worth at least looking into. I plan to use a laser device I bought (a laser cap with about 200 laser diodes) every other day for 30 minutes each time consistently for 6 months. During these 6 months, I will not be using ANY other hair loss treatment, except for ketoconazole shampoo, in order to isolate the results of the laser treatment only. Below, I have taken pictures of the CURRENT state of my hair, before beginning the laser treatment. You should be able to notice a receded hairline as well as a decreased density on top (though it is hard to see with the lighting). After using the laser for 4 months (so around March 10, 2017 - Update: May 10, as this will mark 4 months after the start of consistent use), I plan to post pictures at the same angles. I plan to do the same at the 6-month mark (around May 10, 2017 - Update: July 10) and one-year mark (around November 10, 2017 - Update: January 10, 2018). Hopefully, those pictures will give an idea how well the laser treatment is working, or if it is not working. I welcome any insight or suggestions as well. I have taken pictures from the front, both sides of my hairline, and a little closer to see the thinning. Update on April 3, 2018: Well, the experiment ended up lasting for 1.5 years from the beginning date! See final photos from the end of this period posted further down the page.
