Does km thick again contain alcohol...or much alcohol? i have a sensitive scalp. i prefer to be able to read the ingredients. i don't like to itch!

Yes, it contains SD alcohol 40-B

why would i use this (Thick Again) versus the Body Mass spray?

It's supposed to thicken your hair, at least the appearance of thicker hair. I'll say that I've used this and the women's version & theirs might work a little better. Beware though, I'm not saying the one I got here on Amazon is a fake but it certainly didn't smell as strong (not that it's stinky stuff at all), it seemed a little thinner consistency, & not quite as effective as the ones I bought in a licensed salon. There's a very good chance these could possibly be watered down, perhaps to get more out of it before shipping. Caveat emptor.

No. You spray it in after towel drying hair. Adds thinkneds and volume. It’s fab!

Can I put Leave-in conditioner on top of this or does it condition as well?

Spray on hair while still moist after shampooing and work into hair follicles then blow dry as usual. I often work in conditioner and add the Kevin Murphy to the mix then blow dry. Does a reasonably good job of hiding sparcely covered scalp.
