About Haven Rubus

Haven Rubus is a high-performance keratin straightening treatment built for dense, coarse, and resistant hair that refuses to behave. It delivers a strong straightening effect with serious discipline, taming heavy volume and stubborn curl while keeping strands soft and full of natural movement. The formula reduces porosity, smooths the hair fiber, and shields each strand from daily external stressors, leaving a sleek, polished, manageable finish.

At its core, raspberry extract works alongside nourishing oils and advanced conditioning agents to replenish lost moisture deep within the cuticle. Together they form a strong protective film that seals the smoothed fiber, locking in hydration and reinforcing the hair’s surface. The result is concentrated control: coarse curls relax, frizz stays suppressed, and the hair gains a healthier, more resilient quality with every pass.

What this treatment does

  • Relaxes coarse, resistant curls for easier daily styling
  • Tames excess volume and delivers long-lasting frizz control
  • Reduces porosity to help the hair retain moisture
  • Smooths the hair fiber for a sleek, polished finish
  • Builds a protective film that shields strands from external stressors
  • Restores softness and movement without compromising straightening power

How to use

  1. Wash the hair one to two times with a clarifying shampoo (Step 1) to remove buildup and prepare the strands.
  2. Blow-dry thoroughly until the hair is completely dry.
  3. Apply the keratin (Step 2) evenly in a thin layer over each strand, keeping product off the roots.
  4. Leave the product to process for 20–30 minutes so it penetrates the hair structure, adjusting time to the hair’s texture.
  5. Do not rinse.
  6. Blow-dry the hair 100% until fully dry.
  7. Seal the treatment with a flat iron at the appropriate temperature, adjusted to the level of hair damage.
