How often should one get a trim?

I chopped all my hair off (from just a few inches above my booty to my shoulders) back in early July. My hair was a bit damaged, so I figured I'd just go ahead and cut the majority of it off in an attempt to start the repairing process.

I'm currently working on growing it back.

So, now that we're in September...I was just wondering if I'm due for a trim? And about how often I should get one?

 But I do tend to use the flat iron somewhat regularly. I try not to use it every day. Like when I'm home, I usually don't use it since I won't be going out anywhere. And usually, I'm home five days a week. But sometimes when I'm bored at home, I'll get there and straighten it.

I'm also planning to dye my hair next week. So, I'm not sure if should trim it or not... (but if I do, should I trim before I dye it or after?)

Oh and I'm also curious about the full moon thing. Hope someone can answer that question!

Thanks Shary!

 

Let me know what iron you are using, and what products (if any, you are using with them)

 

Much love, Shary

     My flat iron is one of those big Con Air (Ceramic) ones. I've been keeping the heat around 13 to 15 as oposed to 20 to 25 like I used to.
 
 The shampoo and conditioner I use is just regular V05...and as I said I use the Pantene deep conditioner at least once or twice a week.

The detangler (actually the only one I could find at the time) is by Suav (it seems to be made for kids...but works just as well on my hair).

I've also been using the Biosilk Silk Therapy on my hair for a few months now. Although I haven't used it too much in the past two months.

And the comb I use on my hair when it's wet is a wide-toothed comb.

I have a round boar bristle brush that I rarely use (today was the first time I used it in a long time). I usually use a regular plastic brush with the flexible plastic bristles.

What exactly are protein treatments? Are those something like deep conditioning?

Any products you guys could recommend for good deep conditioners (if the Pantene isn't enough), the protein treatments and any other products I need to be using ...etc. would be greatly appreciated. :)
