Shiny Optical Illusion

Q: My boyfriend says that whenever I wear shiny clothes, such as a silk or satin blouse or dress, my hair looks shinier too. Is this a coincidence or could it be optical illusion? The length of my hair is just below the shoulders.
A: The honest answer to your question is that it could be both. When the hair is healthy, it has a naturally, satiny sheen and this can be enhanced by wearing an equally shiny fabric. You can also create an equally vibrant enhancement by wearing a matte finish fabric, such as a wool or felted cotton.
However, it is unlikely that your hair would be made to appear "shiny" by the presence of a complimentary or contrasting fabric finish alone.
So, because your hair needs to be healthy and have its own shine already, the result of wearing a shiny fabric is "coincidental" in that sense. It wouldn't be possible were the hair not already shiny.
However, it is an optical illusion that the hair appears even more shiny and satiny when paired with a shiny finished fabric. The type of fabric you wear on your body has no bearing on the condition of your hair. However, silks and satins offer low-friction and therefore are less likely to cause damage to the hair from rubbing and brushing against the hair.
