Hair cleaning is a difficult problem from the point of view of trace analysis. The aim is to separate the elements of endogenous origin from surface contamination. This is scarcely possible since some of the endogenous elements are readily eluted [42] and substances can also be incorporated under optimal conditions [43,44]. Human hair can be very soiled on account of intrinsic contamination (such as sebum, shed epithelial cells), environment, workplace, personal hygiene (hair care agents). Hair sprays can envelope the hair follicle and the ultrasonic bath only effects partial removal of the coating. 

The polymer polyhydroxybutyrate (PHB), a polyester of 3-hydroxy-butanoic acid, is completely biodegradable as it is an ideal food for microbes. By copolymerization with another hydroxyacid, such as 3-hydroxypentanoic acid, the polymer can be tailored to take it suitable either for molded articles such as shampoo bottles or thin films for plastic envelopes or carrier bags. PHB is tradenamed Biopol by ICI. Most of the polymer that the company makes is used for packaging, agricultural products, and items of personal hygiene. Wella, the German hair-care company, sells its Sanara brand of shampoo in bottles made of Biopol and has reported increased sales as a result.
