drying question about Foam

[mjd50]

How long do you need to wait for the Foam to dry before you can wash your hair.
Spectral DNC says to wait 3 hours before washing. Do you have to wait that long with the foam?

You have to wait just as long with the foam, I think it says 4 hours. Why would you want to wash your hair though? The foam feels like you don't have anything in it. Wash your hair before application then apply the foam. With these type of products, you would want it in your hair as long as possible for it to work.

It dries in minutes... but you should leave it on your scalp for at least 4 hours for it to be basorbed and take effect.

Why would you consider washing you hair after applying the foam? It does not make a mess and is easy to style your hair afterwood, even make you hair appear thicker, which is nice. If you had to wash it do that first, then wait until all is dry then apply the foam. I use it and it works great!
