Dominant Arm Smaller Than Weaker Arm

I have a muscle imbalance problem here. Not to sure how common it is but here goes...
I've heard of loads of muscle imbalances where the weaker arm is smaller but mine is the other way round.
My dominant (right) arm is almost half an inch smaller than my weaker (Left) arm. Mainly tricep difference but some slight difference in biceps peaks....
I've only been training for 8 weeks and seeing good results apart from this imbalance thing.
When I started there was only a 7mm (0.27inch) difference between the 2 arms now after 8 weeks there's a 10mm (0.39inch) which is worrying me that I'm making the imbalance problem worse.
Strange because after 4 weeks it progressed then on week 8 just totaly went another direction as can be seen below:

(L=Left arm R=Right arm)

Started: L: 397mm R: 390mm (7mm difference)
4 Weeks in: L: 403mm R: 398mm (5mm difference)
8 Weeks in: L: 413mm R: 403mm (10mm difference)

I've stuck to the exact same routine throughout the 8 weeks which mainly consisted of barbells, EZ bars and machines for arms. Kept the volume pretty low for isolation arm exercises though.
About to start my new routine which is going to consist of more dumbbell work for arms.

So my question is, if I go to failure for each arm seperatly, like seated concentrated curls and single arm over head extensions, will this imbalance thing sort itself out? I'm worrying that it will make it worse, but it's different to what I've been doing so I'm hoping not, thanks.
 
I've been training for years and years now and my dominant arm is still about a 1/4" smaller than my nondominant arm. Not sure why but I don't really care. It's not noticeable to anyone but me and only me when I have a measuring tape around my arms.

If I were you I wouldn't worry about it. There is much more important stuff to worry about. Like improving my deadlift lol

Yeah I hear u there mate I'm not worrying about how they look rite now I'm worrying that it will get worse. I'll end up looking like some chronic masterbater by Summer if it keeps goin in wrong directon lol.
 
Lmfao AllKinds chronic masterbater.. I got this issue also.. some people recommend going 5lbs heavier with the smaller arm or even starting off with the weaker one and then the stronger one

I was thinking the same , could possibly try squeezing them out with the non-dominant arm, as a plus would feel like someone else was doing you.
