What is this study about, and what's involved?
This questionnaire is part of an ongoing research project into hairdressing and hair-care practices. The aim of the study is to get independent evidence of the effects of shampoo use on hair - more precisely the effect of reducing the frequency of shampooing on hair. To take part in this study it is necessary that you reduce the frequency of shampooing by at least one day for 2 weeks, so any differences in hair condition as a result of less frequent shampooing can be assessed. For example if you shampoo every day, then shampoo every other day, if you shampoo every 3 days, then shampoo every 4 days etc. Please don't  use any more amount of shampoo in the following wash - just the same as you usually do.  It is OK to just use water inbetween shampoos. Please make a note if the effects on hair after 2 weeks are any different to the effects on hair after just one week, as it may be the case that your hair will adjust to less frequent shampooing and effects may change over time. Preliminary results from the ‘no conditioner’ survey indicate that not using conditioner means hair needs washing less frequently, and looks less greasy, so if you are going an extra day without shampoo and are worried that your hair may look greasy, try using less/no conditioner, but if this doesn't apply to you then just stick to your usual routine, except for leaving the extra day.
 
We are exposed to constant marketing information from businesses whose aim is to get as many people using as much product as possible for commercial ends. It is therefore important to have independent sources of evidence, especially when using or over-using unnecessary products that can be damaging to hair, to our heating bills (heating water costs is typically the highest energy consuming activity that takes place in our homes) and to the environment.
