RESULTS: ALL HAIR LOSES PROTEIN<br />
• Protein loss can be detected<br />
after just 5 minutes of exposure<br />
<strong>to</strong> water<br />
• Protein loss increases with time<br />
• Chemically <strong>damage</strong>d <strong>hair</strong> loses<br />
more protein than virgin <strong>hair</strong><br />
• Measuring protein loss provides<br />
early detection of <strong>damage</strong>,<br />
before it’s <strong>to</strong>o late<br />

Extraction Time (min)<br />
• Protein loss at 60 minutes is equivalent <strong>to</strong><br />
approx. 0.1% of <strong>to</strong>tal protein from virgin<br />
<strong>hair</strong> <strong>and</strong> 0.4% from bleached <strong>hair</strong><br />
(measured by Modified Lowry assay)
