As an international CRO with over 17 years of experience in hair care tests, CIDP, has developed different methodologies to substantiate innovative claims for hair care products. With a highly qualified and GCP and GLP trained team of biologists, dermatologists, and hairdressers, CIDP proposes various ex vivo and in vivo tests on hair care. In addition, owing to its strategic location in cities like Rio de Janeiro and New Delhi, CIDP has access to the biggest cosmetics and hair care consumer markets in the world thereby easing the recruitment of volunteers of skin phototype II to V with different types of hair and particular lifestyles and habits.
Amongst the Ex vivo models, CIDP proposes various assays on natural hair of different ethnic origins (Asian, African, Indian and Caucasian) to substantiate claims such as fiber resistance, brushing efficacy, shine, color lasting, hair growth or fall. Furthermore, the hair strands can be exposed to external stressors such as UV, air, and water pollution and assessing different biomarkers such as Malondialdehyde (MDA), free fatty acids, the melanin and protein content, and Tryptophan degradation.
In terms of In vivo or clinical evaluation CIDP proposes :
- various medical scales (dandruff, hair fall, hair breakage, hair shine),
- experts grading (elasticity, resistance, color efficacy, damage, repair, shine, straightening efficacy) and
- consumer’s evaluation including quality of life questionnaires.
High-definition imaging with standard repositioning components is another tool that hair care specialist routinely incorporates in the study designs for substantiating clinical claims and providing images that can be used for marketing purposes.
CIDP has also set-up new Innovative involving real life sun exposure, real-life sea exposure, swimming-pool exposure, or even real-life sports activities to better support pioneering cosmetic claims. It allows offers the possibility for clients to combine both the ex vivo and in vivo techniques in a single study to derive the best results for their active ingredients or end products.
There are various testing services offered by CIDP for hair and cosmetic products and all the tests are tailored as per the client’s needs to focus on specific claims of products and/or product kits such as anti-pollution, damaged hair from chemical aggression, color protection, hair shine and volume, breaking and hair fall, straightening procedures but also focus on upcoming claims requested by consumers such as “hair faint” (great straightening efficacy).
