My hair has been falling out since 2005. I've been to many doctors, taken many meds, shots in my head, purchased every shampoo advertised, spent thousands of dollars trying to get my hair to regrow. It only lead to devastion, disappointment and less money in my pocket. I was eventually diagnosed with alopecia. I finally decided to give up and embrace my bald head, then my dermatologist said she needed to check my iron levels. I explained I had my iron checked the week prior by my primary doctor, and they were normal. She said she wanted to check my feratin levels. Turned out it was extremely low, and she recommended an iron supplement. I wasn't expecting any changes, but I was also feeling lethargic and fatigued regularly so I decided to research the best one to take. I came across this one on Amazon, saw the mixed reviews but decided to give it a try for a year to see if it worked- after all I had no expectations, but you have to give things time to work. This is my hair after 5mnts. Instead of spending thousands on my hair, I'm spending $60 every mnt to get this along with the elderberry drops. I'm not sure if the rest of my hair will regrow as it has been bald for so long, but I'm extremely impressed with the growth it has made so far. I am still hopeful though. Thank you Mary Ruth! You're the Truth!
