Your ends ARE split. Just because you can't see it doesn't mean it isn't there. Splits start at a microscopic scale. Like this split in the image below is 1/10 the size of this line -. So by the time splits grow to where you can see them, little pieces of sizes you can't see have been falling off like dust. And just coz a hair doesn't look split doesn't mean parts of it haven't fallen off and so you're looking at a partial hair. The only reason hair would break if you're not being rough with it is because it's weakened...and one way strands weaken is if parts of them are shaven off either by the elements or just regular styling or just simply, growing old like all organic matter does.
Clearly these pieces of the strand will break off and the same effect will happen further up the strand. If we could see damage this small, we could cut off at 1/10 of a millimeter and stop it. But we can't.
This is why it's futile to LOOK for splits. You can't possible see them when they are small nor can you scrutinize each one of the 100,000 strands. What's more, unless you have a caliper that measures the strand from base to end, your eyes would not tell you if the cuticle has been shaven off. So why bother when it's not really telling you anything?
To prove how silly it is to trust your eyes on whether splits are there or not, I posted this image:
No one could argue that the strand to the right is split coz we can see the branched out arm. It also looks thinner than the one to the left which is another give away that it has had some damage. But if that arm had broken off, would you tell if what you were looking at was a damaged lock? If you say yes coz it's thin, then you are claiming that you always compare the thickness between stands...which we know isn't easy considering our strands are kinda flat so depending on what side your looking at and that it isn't twisted they may look different.
Now here comes the interesting point: you know the strand to the left that we agreed looks whole? News flash: it's a damaged strand too! I cheated by erasing the arm that had peeled off just to make the point that looking at strands cannot tell you whether they are split or not. Below is the true image with the missing arm back in place:
The sensible thing would be to dust regularly. Don't wait for breakage to tell you that your ends are damaged or very large splits to happen whereby you have to cut your hair. KNOW that organic things wear regardless and know that it's inevitable and just maintain your ends in good shape by dusting regularly. And if you haven't been dusting for a while, you do need to do a good sized trim and then from now on dust on a schedule. If you dust early enough, you can get away by taking off very little and stopping breakage.
I don't think there's any way to eliminate breakage completely (especially if you have fine strands) but you can minimize its ability to rob you of good retention by keeping your ends whole by dusting early before splits grow to where you can see the breakage.
. Hair breakage is not normal right? Can it be totally avoided?
. So that means I have to get the right shears... and learn how to trim it 
erplexed. So when my hair is healthy it wont break at all??? and Thank youuu 
. But I am thinking if I can find a way to cleanse my hair better and give it a nice trim my problem would be solved. I never even thought about the products causing breakage even though my hair feels good. It does not feel dirty or anything....
