Description

A weightless invisible curl enhancer for fine wavy and curly hair β€” Baobab Seed Extract and Biotinoyl Tripeptide-1 add moisture and strength while a light hold formula defines waves without weighing them down.

The Moda Team Review

Fine wavy hair has a styling problem that most curl products make worse. Anything too heavy pulls the wave flat. Anything with too much hold makes fine hair feel stiff and stringy. Killer Waves is formulated specifically for this gap β€” it is the lightest styling product in the Killer Curls family, designed to enhance the wave pattern that is already there without adding enough weight to compromise volume or movement.

The invisible formula means there is no residue, no crunch and no visible product in the hair once it dries. Biotinoyl Tripeptide-1 strengthens the hair shaft and reduces the breakage that fine wavy hair is prone to. Baobab Seed Extract provides lightweight moisture that prevents the dryness that causes frizz on fine textures. The wave sets as the hair dries and the result is natural, bouncy, defined movement that looks like your wave pattern at its best.

Why Moda Carries This

As a White Haven Kevin Murphy salon, we reach for Killer Waves when a fine wavy client tells us every curl product she tries either kills her volume or makes her hair feel coated. Killer Waves solves that problem specifically β€” it is the answer to β€˜I want my waves to look defined but I cannot use a curl cream.’

Key Active Ingredients

  • Baobab Seed Extract (Adansonia Digitata): Lightweight moisture that penetrates the shaft without coating the surface β€” keeps the wave pattern hydrated and flexible without adding weight.
  • Biotinoyl Tripeptide-1: A biotin-peptide complex that strengthens the hair shaft and stimulates the follicle, reducing breakage on fine wavy hair during manipulation.

Moda Pro Tip

Apply to soaking wet hair immediately after conditioning β€” work through lengths with fingers, scrunch upward once, and leave completely alone. Fine wavy hair air-dries faster than curly hair and the temptation to check it is high. Any manipulation while the wave is forming breaks the pattern. Leave it until one hundred percent dry and the waves set themselves.

Not the Right Fit If...

Not the best choice for medium to coarse curl types that need structured definition and hold β€” Killer Curls cream or Killer Twirls will give more result. Killer Waves is specifically for fine wavy and fine curly hair where every other curl product is too heavy. If your hair is fine but you want more definition, Killer Twirls used very sparingly is the next step up.

How To Use

  1. Apply to soaking wet hair after conditioning.
  2. Work through lengths with fingers, scrunch upward.
  3. Leave completely alone until one hundred percent dry.
  4. Scrunch gently with dry palms once fully dry if needed.
COMMON QUESTIONS

Product FAQ

Weight and hold intensity. Killer Waves is specifically for fine wavy and fine curly hair where anything heavier kills volume. It has a lighter hold and an invisible finish. Killer Twirls is a leave-in crème with more hold and more moisture — better for medium to coarse curl types.
No β€” it is an invisible formula. Once dry, hair should look naturally defined with no residue, no cast and no product coating visible. If hair looks coated or feels heavy, the amount applied was too much for the hair density.
It depends on the individual strand. Killer Waves is for fine strand diameter specifically. If you have many fine strands and a dense overall head of wavy hair, Killer Waves may not provide enough hold β€” Killer Twirls might be a better match. Start with Killer Waves and step up if more definition is needed.
Yes β€” on low heat, diffuser held still over each section. Killer Waves is very light so the wave definition under heat will be softer than Killer Twirls or Killer Curls cream. If diffusing and wanting more definition, Killer Twirls is the better match.
Yes β€” colour-safe and sulphate-free. The Biotinoyl Tripeptide-1 also helps with the strand fragility that highlighting can cause on fine hair, which makes it a particularly good match for fine highlighted wavy clients.
