Our Approach

As a science-led brand, isima meticulously vets every ingredient for safety and efficacy to align with our TriModal Method™. Through rigorous clinical and consumer trials that span diverse hair textures, types and damage levels, we test and confirm each formulation’s performance with real people like you.

A young woman with long, voluminous curly blonde hair and natural makeup looks at the camera with a neutral expression, wearing an orange top against a plain white background.

Throughout our development process, we collaborate closely with trichologists, dermatologists and clinical research organizations [CROs] to test every product—instrumentally, clinically and in real-world conditions with both hairdressers and consumers. Each formula is blind-tested over a minimum of four weeks to assess its performance and consumer satisfaction, ensuring that our products deliver exactly what we promise.

Every product is thoroughly tested to confirm both safety and efficacy.  Depending on the formula, this may include: 

Dermal + Ocular Safety 

  • Dermatological patch tests to verify scalp compatibility 
  • Ocular irritation assays to assess tolerance around the eye area 

Hairdresser Evaluations 

  • Throughout formulation, professional stylists assess each product to guarantee it meets the performance standards expected in a salon setting 

Consumer In-Use Studies 

  • Independent trials with 30–70 volunteers over at least four weeks 
  • Post-trial questionnaires capture real-world feedback on usage qualities, effectiveness and tolerance

Blinded Clinical Trials with Expert Grading
[Iconic Densifying Scalp Serum and Súperbomba Triple Repair Peptide Mask] 

  • Trained clinicians assess key parameters such as scalp health, hair density and strand quality 

  • For example, our Iconic Densifying Scalp Serum underwent six months of blinded evaluation

Objective Instrumental Testing 

  • Laboratory assays on hair swatches [think shine quantification, breakage testing, cuticle imaging, bond repair analysis and more]

All studies are performed by independent, industry-recognized organizations under standardized protocols, ensuring every claim is underpinned by rigorous testing data.
