Thank you! This produces an oily substance called Low porosity hair tends to be tightly compacted and repels moisture when wet. Generally low pH up to pH 7 does not really change the cuticle but raising it to 8 and above causes the cuticle to lift up (see the diagram below) and this is when real damage can occur since the cortex is exposed to the elements.
