Male pattern baldness does not seem to run in my family, from my knowledge. Now, to give you an insight of when my hair loss begun: it started when I was 14 after crash dieting. I was eating around 300-800 calories per day, and I was swimming around 3 or 4 times a week. I had also fainted 3 times during this process. This was in the summer of 2014. Furthermore, during December of the same year, my hear began to shed in a mass-amount. It wasn't noticeable, especially since I began getting my hair bleached white-blonde which plumped the strands. Back to my diet, I got so used to eating less so I never went back to my usual intake which was around 2500 calories daily. I was eating around 1000 calories daily; I was too scared to eat above that, in fear of gaining weight again. The diet persisted for years to come, and my hair was continuously shedding and losing density. But again, it wasn't noticeable to others since my hair was plumped by the bleach. But then, during September of 2016 (16 years old), I got my hair dyed back to its original dark-brown colour, and my hair looked T H I N. My hair still appeared to be plumped by the dyes, but the contrast between my hair colour and my scalp made my hair appear thinner. So then, I decided to let my hair grow out, whilst gradually getting the colour cut off. This took around 6 months; the colour was completely gone from my hair, and my hair went to its original fine texture (March / April 2017). Furthermore, my hair looked so thin all over now my hair went back to its original texture. But, I didn't think of it much because I was so overly focused on clearing my skin. And to keep in note, I was still on this low calorie diet but it was even worse and harder for me to eat because I had cut out dairy and sugar. I was quite limited on what I could eat, without fear of gaining weight or getting acne. Since then, my hair texture and density has kind of remained the same, the density has decreased slightly but my hair still looks horrible nonetheless. (I'm now 18).
Now, I'd like to move onto other symptoms which my body was having. I had chronic fatigue, having low energy, bad mood swings, heightened anxiety (especially when I would wake up, I would feel severe anxiety for like no reason), feeling cold all the time and a very low libido (I would feel asexual some days lmao). I do believe I also have quite low testosterone levels.
I have been to a doctor, she said it's 'diffuse thinning' after doing a scalp examination, and she said that it's most likely due to my calorie restriction. (Keep in mind, the thinning is on the top and sides equally. I have noticed an equal density between the two. My hair line has remained the same since I was 13 or 14; my hairline is disgusting nonetheless and looks worse because my forehead is at least 10 inches big.) She did a blood test, and everything was fine besides folic acid levels.
Now, I do take supplements and have been taking them for quite some time. The supplements include saw palmetto (160mg), biotin (3000 mcg), and other ingredient which are good for your hair. I also take omega-3 supplements, along with iron supplements and folic acid supplements. I have been on Accutane for a week too.
