Since this is a curl-defining gel aimed at both hydration and hold, specifically designed for curly hair types 2C to 4A, I prefer using Polyquaternium-11 over PQ-10 or PQ-7.

PQ-11 offers a stronger film-forming effect that helps with curl hold and frizz control, which the other two don’t provide as effectively.

For the conditioning aspect, I’m relying on Guar Hydroxypropyltrimonium Chloride, which adds softness and manageability to the hair at a low inclusion rate.

That said, I was wondering if Guar could be replaced with Xanthan Gum. I understand they don’t offer the same conditioning benefits, but would xanthan be a viable option in terms of texture and viscosity?

I agree with your suggestion regarding Aloe Vera extract and Panthenol — I’ll reduce both to 0.1%, since their benefits at higher concentrations are minimal in a leave-in gel and they’re mainly marketing claims.

I also decided to remove Sorbitol from the formula, but in doing so, I’m wondering whether I should keep Glycerin at 1% or increase it to 3% to maintain proper humectant function, without causing stickiness or frizz in humid environments.

As for the gelling system, since HEC is more readily available locally than AquaStyle SH-100, what do you think about combining both?
My idea is to use HEC for viscosity and smooth texture, while AquaStyle SH-100 provides film-forming and hold, supported by PQ-11.

Would love your thoughts on this combination.
