I found a review of Vitamin B5 on Amazon. This woman experienced extreme hairloss/shedding and was able to stop it. I am going to see if she can give us the list of supplements she used but she says she used Barlean's Organic Oils Essential Woman which contains Evening Primrose Oil and noticed a decrease in shedding after that. Here is here testimonial: I was really excited to start this supplement, as I am very much into a more natural approach to combating my acne. I have have acne since about 13 years old. Everything short of accutane, everything. So.. I started this supplement about 6-7 grams a day. About a week in, i noticed a good amount of hair loss. I would say I am losing a little over double what I would normally lose. I have fairly thick, long, undyed hair that I rarely ever style or apply heat.I did notice that my acne did seem to calm down, I definitely saw a reduction in oil production. I would normally blot every single time I used the restroom, and now when I test, there is barely any oil! This is huge. The hair loss though is scaring me. I take a variety of supplements in addition, I decided to add biotin, and extra B complex. I have only been taking B5 for about 2 weeks .I intend on continuing though greatly reducing how much I take. Probably only 3G as opposed to 6-7. If it helps anyone.. I am 125lbs, eat a healthy, pescatarian diet, hardly and dairy, lots of coffee (this could be a contributor?) I drink heavily usually once a week.I will update in a month or so regarding the hair loss. I really hope I still see the oil reduction on a smaller dose, and for my hair to come back!---9/22/14after just two days of going from 6-7g to 2-3g the oil has seemed to return. I am ordering some other supplements to help with hair/skin. MSM, read about it.9/2Well I am still losing an alarming amount of hair, and have spent over $150 on supplements to slow/reverse the hairloss. PLEASE USE CAUTION. Look into the link between b5 and hairloss. I even read about it first and thought it wouldnt happen to me.. it has. I really hope the new supplements etc I am waiting for help this issue. Try other remedies first.... I dont really understand how this is happening considering this isnt a fat soluable vitamin and you are said to excrete what you dont need/use..--update 11/11/14I continued to lose a lot of hair, especially in the shower. It definitely was apparent to me. I recently started taking a supplement called "essential woman" by barleans greens because I read that Evening Primrose Oil can slow hair loss. I dont know if its the mixture in the supplement or just the EPO but my hairloss has dramatically decreased. I am finally feeling like i might have a handle on this situation. I still lose hair, but i would say its more like 50-70 strands a day as compared to the maybe 200+ i was loosing before.Update 12/1/14My hair seems to have stopped shedding. I cant say I know what exactly it was.. maybe the loss ran its course, I still regret this though. I spent SOO much money trying to combat the hairloss. I am still taking EPOIf you are experiencing hair loss please feel free to contact me. I feel like I tried everything... I know how scary it can be.
