I experienced chest pressure abit heavy breathing, and a pressure on my thyroid like if someone poked a finger on your neck and held it there for 10 minutes, and my hair thinned out crazy in 2 months, basically gave me thin spots. Like alopecia areata, my thick crown hair in one area got double as thin in 2 months I was shocked when I saw it and it happened graduelly, then saw another small thin spot of the size of a coin, after this I had to quit it, Happaned to another guy on this forum and his thin spot that ru caused never grew back and he has trouble covering it up now. After this I got desperate and bought ru from purity prod. After only one application, I went outside from my home and stopped, I felt like my body was suddenly shutting down it felt like I was dieing, the worst feeling and weirdest feeling I have ever felt in my life, I went back home and sat on my bed and it took like 5 minutes to feel normal again, 2 weeks after this immense shock to my system I got telogen effluvium, and lost 1,000 hairs daily for 2 weeks. Clumps of hair came out in the shower, litteraly clumps of hair. I counted all hairs and it came up to total of 1,000 hairs daily no f*****g joke it was crazy, im not even sure if all the hair even grew back but did see some short hairs in one spot only...... This is why im afraid to try ru again from another company btw this Happaned when I was 27. Im 34 now.
