Wash day, in order

Follow the three-step sequence printed on every bottle to get the full benefit of our formulas on wash day.

1

wash the hair

Cleanse the scalp and strands with shampoo to remove buildup so the hair cuticle is ready to take in the treatment.

2

apply the mask

Work the deep treatment through clean damp hair from mid-lengths to ends, let it sit, and rinse thoroughly with water.

3

seal and dry

Distribute a small amount of leave-in evenly through damp hair before blow-drying or setting under the dryer.

Silicon Mix

Made in the Dominican Republic

Laboratorios Rivas makes every bottle of Silicon Mix in Santo Domingo. Our line grew out of Dominican salon culture, where stylists treat natural, relaxed, and colored hair with rich masks under heat to keep strands soft and manageable.

We pour our formulas into plain jars and bottles that run up to one gallon. Dominican stylists use generous amounts of mask during every wash day, so we focus on dependable ingredients like ceramides, keratin, and silicones rather than fancy packaging.
