Here's a study me and my colleague authored in November 2002 exploring the relationship between porosity and tensile strength of hair fibers.

Over the years, many individual studies have been conducted regarding the extent of damage imparted to hair. These studies deal with the damaging effects of various chemical processes such as permanent waves, permanent colors and hair bleaches.

The most commonly employed method to quantify this damage is the measurement of change in tensile properties of the hair. This method takes two to three days in the preparation of samples of hair fibers. It also requires a minimum of 30 to 40 fibers for statistical analysis. Therefore, there is a need for other simpler methods that are equally valid and less time-consuming.

One such method could be the determination of hair porosity or water uptake of hair fibers as described by Valko et al and by Menkart et al. However, to the best of our knowledge, no study so far has correlated the tensile strength method with the water uptake (swelling/porosity) method following chemical treatments such as permanent
waves, permanent colors, hair bleach, and permanent hair relaxers.

Therefore, we have conducted a study whose purpose was to validate the porosity method against the tensile strength method. Another purpose of this study was to use these two methods to compare the magnitude of hair damage between permanent waving, permanent coloring, hair bleaching, and permanent straightening processes. Finally, this study ranked the various chemical processes in terms of their hair damage potential. We believe this is the first comparative damage ranking for various chemical processes in the hair care field.

I guess I might as well get the obligatory and shameless plug about Avlon out of the way with this post.

If you haven't already heard about what we do, here's a simple 1-page company profile that GCI did for us:

Global Approach


Although ethnic hair care has recently become a growing focus in the industry, Avlon Industries has been specializing in the category for 18 years, due to the foresight of its founder, Ali Syed. As an intern in 1974, Syed realized that there were not many people interested in formulating for excessively curly hair. That's when he decided to specialize in ethnic hair. "I like hair anyway because it uses more chemistry than color cosmetics. So, I decided if I specialize in this area, I'll have less competition and can probably do well in life," explained Syed.

From the begining, when Syed was performing literally every duty in his company himself, to today, where Avlon is a multinational corporation, Syed credits its success to his equal knowledge of both business and chemistry. "I was able to go from chemistry to the management world, allowing me to see things from many different angles," said Syed. As the head of such a flourishing organization, however, Syed still spends 15 percent of his time in the lab; it is still his first love. But with eight different laboratories that comprise Avlon's state-of-the-art research center, Syed also can rely on his team's skills to make the company thrive.

And thrive, it is. When Syed first conceived Avlon, he pinpointed several problem areas in existing business methods for salon-based ethnic hair care products. First, he set out to truly educate the hair stylist about the product chemistry, and undertaking that wasn't popular. Even more significant, Syed saw lack of integrity in ethnic hair care business practices, especially in promises made to hair stylists regarding products remaining in the professional market and not merging into the consumer market. "From a business standpoint, integrity is crucial," emphasized Syed. "I felt there was an oppurtunity to make sure the product stays professional. The hair stylists didn't believe us right away - it took five or six years for them to come around."

Logically, Syed saw the global marketplace as the perfect venue for Avlon's products, because many countries include people with excessively curly hair. The company first conquered Europe, where its products have been top sellers for the past 15 years, and is now on five continents and in about 25 countries. Although Avlon's top market is the United States, following closely are Europe and South America. Born in India, raised in Pakistan and educated in Africa and the United States, Syed maintains the importance of global understanding. "I always have the global approach and luckily the I work is like a mini-United Nations," he explained. "We have all nationalities, all religions, all kinds of people working together."

Avlon's employees and customers both benefit from Syed's emphasis on the importance of integrity in the products he endorses. "The customer comes first and along with that, we treat our employees with respect. If they're not taken care of, they're not going to take care of the customer that well," explained Syed.

Because Syed doesn't believe in retirement, there seems to be no obstacle in the way of his dream becoming a reality - for Avlon to become a true multinational organization and a force to be reckoned with. "We are getting there. We are well on our way," said Syed. "Work hard and you'll be successful."

I got lucky circa 1997 when some guy somewhere decided to publish a book regarding hair care. I cooked up a section for him regarding various popular solutions in the ethnic haircare industry. Have a look:

The "ethnic hair and hair care" is served by products and services devoted to the care of excessively curly hair. Primarily, it is the African-American segment of the population that has the type of hair for which ethnic products are designed, although some Caucasians with naturally curly hair can also use these products. Worldwide, this same industry is devoted to many others with similar hair textures, such as Africans, African-Caribbeans, and segments of South American and Middle-Eastern populations...
