All-natural hair products are hard to find. Especially mousse for some reason. What can be found is outrageously expensive. We didn't think there was any hope of us making our own, though, when we can hardly get dinner on the table. Until we discovered this recipe for homemade mousse:
1/4 tsp. plain gelatin
1 cup boiling water
Mix together thoroughly (that's the important part, it can take a few minutes for the gelatin to completely dissolve), allow to cool, and use on your hair.
That's it. We stored it in an old hair gel bottle and it works great. You don't get that fun foamy white stuff out of it, but it does hold hair steady very nicely. You can adapt the amount of gelatin if you want a bit stiffer mixture; DOB likes 3/8 teaspoon per cup of water.
