How our checker rates it

ModeRatingWhy

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.

What water-soluble silicone ingredients do
