New Research on Dandruff
Dandruff is a chronic scalp condition for approximately 50% of the population worldwide. Because its most visible symptom — flaking — is unattractive and dandruff can make the scalp uncomfortable, it’s no wonder that hair care scientists at P&G Beauty conducted extensive clinical studies into the cause of dandruff.
These studies led to breakthrough research, which has been published in prestigious medical journals, about both the cause and treatment of dandruff. “In addition to our scientific studies,” notes Dianna Kenneally, senior scientist at P&G Beauty, Cincinnati, Ohio, “we talked to sufferers to learn where they would go for help in controlling this chronic scalp condition. We learned that 58% of both men and women are likely to consult their hairstylist, barber or other salon professional for advice on dandruff control, proving the importance of the salon professional in educating clients about scalp, as well as hair care.”
What’s New About Dandruff?
Dandruff is a chronic scalp condition characterized by excessive flaking and associated with itching and irritation. Scientists now believe the leading cause for dandruff is a naturally occurring microscopic fungus called Malassezia (mal-uh-SEEZ-ee-uh), The fungus feeds on the scalp’s natural oils and creates by-products that cause irritation to the scalp. The body reacts to the irritation by accelerating the amount and rate of flaking of dead skin cells.
Symptoms and consequences of dandruff include excessive and noticeable white flakes on the scalp, as well as itchiness, dryness, tightness and irritation. If a dandruff sufferer scratches his or her scalp excessively, the unhealthy scalp condition can also lead to damage of the hair cuticle.
How to Treat Your Client’s Dandruff
An anti-dandruff shampoo can effectively treat the condition in over 90% of people who have flakes and itch, according to clinical studies. Before recommending an anti-dandruff shampoo to clients, salon professionals should review the ingredient listing for those most effective in treating the cause of dandruff- pyrithione zinc, selenium disulfide and ketoconazole. Of these ingredients, pyrithione zinc is the best-selling OTC anti-dandruff ingredient. In addition to treating dandruff, hair care products containing pyrithione zinc have also been shown to be as mild and gentle to the hair as the best-selling cosmetic shampoos and are safe for everyday use, even on color-treated hair.
It is especially important for salon professionals to encourage use of a quality anti-dandruff shampoo every time a client cleanses his or her hair.
By being aware of the symptoms and treatments of dandruff, and sharing their knowledge with clients who either ask about present the symptoms, salon professionals can strengthen the bond of trust with their clients, leading to increased loyalty as well as healthy, shiny hair that enhances the artistic work of the salon professional.
The study was conducted in 2003 among 800 dandruff sufferers in the U.S.
