SLS downside to shampoo?
My shampoo have SLS on it, and I think it is the cause of the itchiness is this true? Is there any substitute to SLS or is there any ingredient that can remove the itchiness of the SLS? Thank you!

Potentially. SLS is not mild. What is your formula?

Synergistic with some capb you can make it milder

It depends on how much you use and what else is in the formula. @sven is right, cocamidopropyl betaine can offset irritation. Some people use SLES in conjunction with SLS for the same purpose (offset irritation).

I personally think it’s a really crap surfactant, the only things going for it are a lot of foam and cheapness.

Out of sulfate free I find olefin sulfonate the best option: also very cheap (funny enough repackers in the UK sell SLES and SLS at a higher price), a decent foamer, easy to use, reacts well to thickeners (and even to salt a little bit), milder than SLES. The only thing, it’s yellow.

SLS is added to improve SLES foam profile

If irritation persists, then you can try a sulfate free shampoo.
If irritation still persists then you can try a cocamidopropyl betaine based very mild shampoo, or conditioner wash (co-wash). -

I am making AOS based shampoo but hurdles to make it thick . AOS based shampoo is eye irritant where SLS +SLES +CAPB based shampoo is less eye irritant .

You’ll need a salt-resistant thickener
Something like Carbopol Ultrez, HEC, HPMC, xanthan gum or combinations of the above.
Anyhow, you’d better start a new thread to ask that.
