Dreadlocks not consistent, thin locs - Needs help!

[beezus]

Hey guys!
I am seeking help with my locs!
They are driving me crazy and I need unbiased opinions on them 
For 15 months I have been getting my hair done around once a month by a hair stylist, she crochet locks and washes my hair. 

After theses 15 months I am unhappy with how my dreads look and believe the dreads on the right side need to be larger. Since they are so small the area is always frizzy. I also believe that since they are not large enough hair is not shedding inside of the dread, which is causing the to stay small and not be as long as the dreads on my left side. This causes a difference in the overall structure in the dreads when you compare the sides, but it is debatable my hair type is different in this area. The woman that does my hair insisted that the dreads on the right would get larger, and said I shouldn't try to combine them because it will make the dread too heavy. 

I am now really concerned that the initial partings were not done correctly. 

I have been looking around most people do not have dreads as small as I do on my right. 
Should I cut my hair because of the difference or will it look fine eventually... 

P.S. Sorry for the ugly mug

I think there are a few things here to think about. I’m assuming your hair texture is kinky?

Here’s what we know - and others please feel free to weigh in (looking at jxbx)

Are you washing them only once a month and are you having them crocheted every month?

For hair to lock, it needs to be able to move and create friction. This is also the part of the process where shedded hair will add to the body of the dreadlock. If you’re crocheting every month, you are essentially interfering with the knots that may have naturally formed since the last crochet. And I also feel like this is what is making your dreads so small.

We typically recommend keeping you hair super clean - oily hair can’t knot! - and letting it move and do it’s own thing.
