Cyclohexasiloxane
Evaporating silicone CG: use with caution
A slightly heavier volatile silicone that evaporates more slowly than D5. Used in serums and heat protectants.
Curly Girl note: Evaporates slowly; often paired with non-soluble silicones.
How our checker rates it
| Mode | Rating | Why |
|---|---|---|
| Curly Girl | Caution | Evaporating silicone — mostly evaporates, but strict CG followers avoid all non-soluble silicones. |
| Relaxed hair | Good | Silicone — coats the strand and helps protect relaxed hair from heat and friction. |
| Low porosity | OK | No concerns for this mode. |
| Protein-sensitive | OK | No concerns for this mode. |
Ratings assume it is listed near the top of the label. After the first preservative or fragrance (likely 1% or less) most cautions soften.
