Sulfate-free, actually: how to read a shampoo label

The phrase on the front of the bottle is marketing. The truth is in the first five ingredients on the back.

What sulfates do

Sodium lauryl sulfate and its cousins are aggressive degreasers — brilliant for dishes, indiscriminate on hair. They remove sebum, yes, but also the lipids that keep the cuticle sealed and color locked in. Treated hair fades and roughens fastest.

The gentler families

Look for isethionates (sodium cocoyl isethionate), glucosides (coco-glucoside) and betaines (cocamidopropyl betaine). They cleanse by surrounding oil rather than blasting it, which is why a good sulfate-free wash lathers softer and rinses without that squeaky, stripped feeling.

Squeaky is not clean

That squeak is friction — a raised cuticle. Healthy washed hair feels slippery, not squeaky. If your current shampoo squeaks, your conditioner is doing repair work your shampoo caused.

Our approach

Every Frenzy Follicles wash — Molecular Silk, Reviver, Clarifying pH+ — is built on the gentle families, then loaded with the actives that matter: silk proteins for structure, humectants for moisture, chelators for buildup. Cleansing should be the start of treatment, not something hair recovers from.
