Hair Analysis Contamination Factors

• Yes, absolutely
• Shampoos and hair dyes can significantly alter mineral levels in hair tissue.
• Permanent hair dyes frequently contain high levels of lead, bismuth, and other heavy metals, which can drastically skew trace element test results.
• Medicated or specialized shampoos often contain zinc, selenium, or sulfur compounds that adhere to the hair shaft and falsely elevate laboratory readings.
• External contamination makes it extremely difficult to differentiate between true systemic mineral levels and surface deposits from hair products.
• Washing procedures in laboratories attempt to remove external residues, but chemical treatments like dyes permanently bind elements into the hair structure, rendering the analysis unreliable for certain minerals.
