This morning I went to my local LUSH retail store (my first visit) where I have just replaced all my toiletries with solid alternatives.
JUNGLE hair conditioner - the description says to rinse it out of your hair, but I have always used a "leave-in" liquid product in the past which works just like a hair gel. The sales clerk informed me that you can just as easily take a small amount of JUNGLE and work it into your hair after you get out of the shower (while it is still wet). I just tried it and it works like a charm!!
The other products I was easily able to replace with solids - shampoo, body lotion, face cream, and deodorant. Tried them all - work beautifully. Really proud of myself cause I'm now back to carry-on only
