FACTORS THAT MAY AFFECT HAIR ANALYSIS TEST RESULTS

Hair dyes contain lead acetate. Results may show an elevated lead level, which should not necessarily be considered as representatives of the body's lead content.

Bleached can cause an artificial elevation of calcium. Samples submitted for analysis should be taken from the area of new growth closest to the scalp or the result for calcium disregarded.

Perming may artificially elevate magnesium levels and the result may not be representative of the body's magnesium content.

Shampoos that are medicated may contribute to elevated levels of selenium and zinc.

Swimming pools contain many water purification systems that use copper sulphate. As a result, high levels of copper may be found.
