Bumble and bumble. Grooming Creme Styling Cream | Smoothing + Subtle Hold | For Fine to Medium Hair, 5 Fl Oz

when I use this it makes my hair a bit flat! How much should I be using for wavy hair ( Male 37 )

Does this protect hair from heat damage from a blow dryer? Does it work okay if I put it on after blow drying hair?

Can this product help to tame grey coarse hair

Is this similar to kiehl's creme with silk groom? i love that product but apparently it's been discontinued & i'm trying to find a replacement.
