This may be strange but does being on T have any impact on hair pigmentation? I am not sure what the problem is with me but I am having an increasing amount of white hairs and it's personally causing me to feel horrific and even nauseous. I wish there was a way to prevent it from happening somehow.
I am in my 20s so I don't know what the deal is. Other people in my family didn't have this. I was thinking it was from stress because I am also having mental breakdowns from other reasons.   I may lack nutrition but I don't eat that bad. I take vitamins but I don't even know if they help. 

I just thought I would ask since T does have a possible effect of hair line/loss.
I hope it's not from T though!

It did in my case. Early in my teens I developed lighter colored hair where my male pattern baldness would develop. I was fortunate that it didn't go very deep but 10 years was long enough to permanently remove the hair in that area.

Well, I can chime in until someone with better info comes along.

Going from T to E has affected my hair color and texture. There are men who start going gray or losing their hair in their teens. I had a neighbor in his 30s who had a full head of gray hair. Though your graying may not -necessarily- be T related. Sorry I can't give more definitive answers. Also, I think there's a hormone called DHT that does stuff to hair, but I don't recall any details.

Don't be scared, just grow it long and be anime

It may not be related to T. I developed a big gray patch in the front in my mid 20s, and nobody else in my family remembers anyone else in the family having that. My dad started going gray in his 20s, but it was the normal areas. Sometimes you just wind up with characteristics that no one else in your family has.

My hair does seem to be a little bit of a different texture since starting T, but I haven't noticed it changing color.

If it really bothers you, you can color your hair. That's what I did for a while because of the big gray patch. Now I keep my hair so short that most of the time it's not that noticeable.

May not be related. About 2 years ago I got temporary hypothyroidism as a result of quitting female birth control estrogen cold turkey. It put my whole body out of whack after 10 years use and grey hairs appeared almost overnight, uniformly distributed throughout all the hair on my head - and not grey but pure white hairs. It's not enough to notice until you're up very close, but it hasn't gone away.

If it's bothering me I just dye it....
