Sleek Two Straightening Conditioner by Sidlab Hair is the second step in the brand’s cult-favorite Haute 1-2-3 smoothing system. Infused with panthenol, hydrolyzed wheat protein and an antioxidant essential-oil blend, this lightweight yet powerful conditioner relaxes natural wave patterns, polishes the cuticle and forms a humidity-proof shield for ultra-straight, glassy hair that stays silky for days. Color-safe, paraben-free and sulfate-free, it delivers runway-level shine while strengthening even fine or over-processed strands—proving that “straight is the new black.”

Benefits

  • Breaks down wave & curl memory for poker-straight styling.
  • Seals the cuticle to lock-in mirror shine and fight frizz for up to 72 hours.
  • Adds strength, flexibility and thickness—ideal for fine, damaged or chemically processed hair.
  • Shields against humidity and thermal tools up to 425 °F / 218 °C.
  • Color-safe, paraben-free, SLES-free; maintains vibrancy of salon color.

Active ingredients

Panthenol (Vitamin B5): Binds moisture, thickens individual strands, boosts elasticity, improves overall strength.

Hydrolyzed Wheat Protein: Small-molecule protein plugs microscopic holes in the cuticle, adding body, smoothness and heat resilience.

Dimethicone + Amodimethicone: Dual silicones that create a humidity-proof, high-gloss sheath for “stick-straight” results without heavy buildup.

Essential-Oil Complex (Sage, Cedar Leaf, Sweet Grass, Lavender, Citrus): Botanical blend that provides antioxidant protection, scalp balancing, light natural fragrance.

Behentrimonium Methosulfate & Cetearyl Alcohol: Plant-derived conditioning pair that detangles instantly and leaves hair soft, not greasy.
