3.1.2. Effect of humidification/bleaching on UV irradiated hair
Fig. 2 shows how the average values of s3 and I3 change on subjecting
UV irradiated hair to humidification (relative humidity
>95%) in water vapor, and a single bleaching treatment of 1 h duration.
Humidification at 200 h UV irradiation has not altered much
the value of s3 (an increase of about 30 ps; compare UV200h and
UV200hW);
