Hi, Perry.

Hello, Valerie.

Good to see you.

Last time I saw you were on the other coast.

We were in New York together, which we'll get to talk about.

On today's show, we're also going to cover lots of

questions, including do low p-8 shampoos preserve color? Can a supplement provide you sun protection?

What effects does hard water have on hair color? How significant are the health risk with taking

topical tretinoin? And what's the difference between aerosol and non-arisol

sprays but first that inane chit-chat. Valerie how was your trip back on eventful hopefully?
