There are a number of cosmetic formulators, hair shampoo manufacturers, as well as manufacturers of hair dye and hair care products of various brands, would no doubt need to test their products on human hair. A rigorous scientific testing process like this can be a critical factor to the success of a product. It will help to reduce liability claims while also providing a much more robust scientific foundation for your product claims and quality.
Testing on hair
Conducting this type of tests requires a number of things. You’ll need to clearly articulate and summarize your product claims and benefits in different groups most of which may include improving hair strength, reducing hair fall or better still, improving hair color among others. You’ll be required to perform certain tests depending on your claims.
Some of the required tests may include testing for frizz control which may include humidity resistance testing for maintaining and managing styles, hair internal structure exams, and tensile strength testing among others. Many products require extensive testing for conditioning, fiber alignment or repeated grooming for checking detangling benefits.
Another area of testing is for dyes and this often requires measuring colour uptake and protection. The effect of these products is most suitably done on hair tresses. This could range from natural brunette colour hair tresses to hair tresses in grey or greyish white colours. It is usually difficult to find colour tresses uniform grey colours or those which have been completely cleaned, with no mix of dyed hair.
The rigorous quality of product requirements may require hair to be further tested on fiber performance with treatment in situations like twisting, torsion on a repeated basis, and testing for static build-up and dissipation. A series of products in areas like split ends and much more will also require hair tresses from natural virgin hair to undergo a variety of test for the mending of split ends after application of products. Other variety of tests could include style retention, fiber alignment, testing for shine, the volume rate of drying, etc.
This is a comprehensive but not an exhaustive list and each of these tests would require some necessary equipment.
Type of hair needed for testing
Tests like these require hair tresses for testing. Grey hair may be used to test for color or dyeing related tests. The challenge in grey or blonde hair is that you may end up with a dyed or bleached product whose consistency in test results is substantially compromised. You will also need a clear understanding of the country of origin of some of these tresses to better align your test to demographics. In summary, you need to know –
- The country of origin
- The consistency of hair tress – Coming from a single person
- Color requirements – Ensuring that hair is presented in its natural color and not in a bleached or treated form
- Length of hair – you may need to test your hair for different lengths and its impacts.
- Cuticle alignment – to ensure that you have a hair tress which is not cuticle free and that all the cuticles are properly aligned
For testing purposes, you need to get hair tresses of similar length and type, either tied in rubber where you can work with individual hair fiber or weft where you can take one strip of hair and work with it. The hair type for testing can be straight, wavy or curly. You will need this depending on the type of test you want to perform.
