Hair Care Market Africa – Trends and Insights

Consumers in sub-Saharan Africa have specific hair care needs and challenges connected closely to the characteristics of their hair, which is typified by tight coils and kinks and fewer cuticle layers than other hair types. The unique characteristics make the natural hair perceptibly more difficult to manage, necessitating tailored regimen to enhance its health and beauty.

To develop hair care solutions, relevant to the local consumer, it is imperative to understand their real needs, and aspirations, and keep updated on local trends.
With its local competence center in formulation design and marketing in Nigeria, BASF strengthened its Personal Care footprint in Africa, to better understand and serve the personal care market demands in sub-Saharan Africa. Based on own market findings, and a recently conducted consumer survey, BASF will talk about trends, consumer concerns and needs in the cosmetic hair care market in sub-Saharan Africa.

Talk Description

Investigating the Physical Properties of Mexican Hair – A Cautionary Tale.

Hair comes in a broad range of sizes shapes and color which can lead to very different appearance and maintenance issues. This leads to a tendency to try and group or classify hair into various pigeon-holes – for example, based on ethnicity. The historical literature contains a number of papers that describe differences in the physical shape of Caucasian, Asian and African hair; and our study initially involved comparing and contrasting the properties of Hispanic hair to this earlier work.

On the one hand, we obtained fiber dimension results for Mexican hair that were statistically differentiated from the aforementioned ethnicities; but, at the same time, the extreme variability of hair becomes apparent. There are huge differences in dimensions amongst individuals of any ethnicity; indeed there are huge differences on the head of a given individual. The presence of statistically significant differences implies dissimilarities; but, in reality, we see how “hair types” can be are far more alike than different. Superimposed on top of this is the things we do to hair – wherein, results will show how very different damage levels were observed within the same ethnic groups in different geographic regions.

Talk Description

Understanding the causes of damage in textured hair

African women have a complex routine; spaced out washdays with manipulation of hair fibers, which could have severe effects on hair and hairline.  Grooming practices play a major role in determining the level of hair breakage experienced. Tensile properties of hair with higher curl vary greatly. These hair types have many kinks and twists along the hair shaft resulting in hair with several fragile points, which leads to matting and breakage. Due to its intrinsic morphological properties, natural African hair is susceptible to hair breakage, with some grooming habits further exacerbating the hair loss. Management of natural African hair typically involves braiding, plaiting and combing. Braiding and combing imparts significant damage on the natural African hair fiber. Appropriate education on grooming practices can help women understand safer practices and minimize damage.

Talk Description

Practical formulation technologies for different curl types

One of the many challenges, which formulators are faced with is creating hair care products for different curl types. Specific hair morphologies of hair have distinct needs for health, maintenance, and protection. Moreover, this talk will address and map the specific curl types and the associated shampoo conditioner and hair oil categories. Challenges for the development of curly hair types do not only involve the product development phase but also the scale up process. Dr Henry Brew will be providing great insights and approaches about creating effective and relevant hair care formulations including lab bench and production considerations. The appropriate selection, handling and processing of raw materials for curly hair including the targeted consumer demographics will be discussed.

Talk Description

Straightening the Hairs. Chemical and Physical Ways.

Hair straightening is one of the cosmetic processes generally known as ‘hair shaping processes’, treatments developed for changing the original shape of the hair. The straightening deals with the fibre morphology that, ultimately, is going to be altered, as it happens also with the chemistry of the fibre.

There are various chemical and / or physical means developed for this process, and their use depends on how long it is required to last the new shape of the fibre.

This presentation surveys several chemical and thermal modalities to straighten the hair and looks into the way the fibre structure is affected and how to evaluate the impairments for possible optimisation of the process, knowing that any such treatment targets the hair fibre stability.
