Why we like it
The Moda Team Review
The answer to ‘I want my waves to look defined but every curl product flattens my hair.’ The only Killer Curls product light enough for fine wavy hair to use without losing volume.
Read full stylist notes
The fine-haired client who has tried every curl cream and found them all too heavy, every mousse too stiff. Killer Waves is the one curl product fine wavy hair can use — her waves are defined and her volume is still there. Kevin Murphy designed the Killer Curls system to address every curl type from fine wavy to dense coily. Killer Waves occupies the lightest end of that spectrum — because fine wavy hair was underserved by the curly product category.

Moda stylist tipSoaking wet hair, scrunch upward once, hands down. Fine wavy hair dries faster than curly — the window to leave it alone is shorter, but the instruction is the same. Touching it while it dries breaks the wave forming inside the product.

Questions? We get them.
Good to know.
The questions we hear most about this product. If yours isn’t here, a real stylist will answer.
Ask ModaHow is Killer Waves different from Killer Twirls?
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.
Will I actually see the Killer Waves product in my hair once it dries?
No — 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.
My waves are fine but quite thick overall — is Killer Waves still right for me?
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 — Killer Twirls might be a better match. Start with Killer Waves and step up if more definition is needed.
Can I diffuse with Killer Waves?
Yes — 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.
Is Killer Waves colour-safe for fine highlighted hair?
Yes — 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.
